REAR PANEL CONTROLS (FIGURE 1)  
4. DVD - SAT - VCR - VIDEO 4 (AUDIO & VIDEO)  
1. FM & AM ANTENNA  
Apart from the audio signal, these inputs will also accept a video signal  
which will be routed to the Monitor Out sockets (No. 7) for a television  
or video projector. The DVD - SAT - VCR inputs also have the option of a  
an S-Video connection (using the Mini-Din connector) or the standard  
Video Composite connection (using the yellow RCA socket).  
AM ANTENNA - An AM loop antenna is supplied with the T742 and is  
required for AM reception. Open the clip terminal lever and insert the  
wire from the antenna. Closing the lever will lock the wire in place  
(Fig. 5). Test various positions for the antenna, but always ensure the loop  
is placed vertically for best reception. Placing the antenna close to large  
metal items such as metal shelves or radiators may interfere with  
reception.  
The S-Video standard allows for higher quality video signal transfer when  
compared to the Video Composite standard. If your video components  
have an S-Video connector use dedicated S-Video leads to connect them  
to the T742 in the same way as described with the Video composite  
equivalents.  
NOTE  
When reception is not satisfactory using the supplied AM loop  
antenna alone, connection of an external antenna is recommended.  
Do not connect anything other than a loop antenna to the AM  
ANTENNA terminal. Do not remove the AM loop antenna. The  
antenna cable to the loop antenna must not exceed 3 meters.  
A video signal fed to an S-Video input socket will be available on both  
the S-Video Monitor Out and Video composite Monitor Out.  
DVD & SAT - Inputs for the audio playback and video signal  
from a video device such as a stereo TV, DVD player, satellite cable TV  
receiver or a Laser Disc. Using twin RCA-to-RCA leads, connect to the left  
and right ‘Audio Out’ of the video device to these inputs. Using a single  
RCA-to-RCA lead (Video Composite) or S-Video lead, also connect the  
video output of the video device; refer also to the description of S-Video  
and Video Composite above in this section. DVD & SAT can be  
used for video playback only. Use VCR or VIDEO 4 if you want to  
connect a VCR for recording and playback through the T742.  
FM ANTENNA - A ribbon wire FM antenna is included and should be  
connected to the FM connector at the rear of the unit (Fig. 4) using the  
‘balun’ adapter supplied. The ribbon aerial should be mounted on a  
vertical surface and placed so that it forms a ‘T’.  
Experiment with placement of the antenna to find the position that gives  
the best signal strength and lowest background noise. An inadequate FM  
signal normally results in high levels of hiss, especially in stereo, and  
interference from external electrical sources. In areas of poor FM  
reception, the tuner sections performance can be improved by using an  
externally mounted FM antenna. A qualified aerial installer will be able to  
advise and fit a recommended aerial for your reception conditions.  
The optical Digital DVD (No. 5) is linked to the DVD input. Select  
DVD to hear a source connected to Digital DVD.  
2. TAPE 1 & CD INPUT  
The coaxial Digital SAT (No. 5) is linked to the SAT input. Select  
TAPE 1 - Connections for analogue recording and playback to an audio  
tape recorder of any type, such as a cassette, reel-reel, DAT, MD or DCC.  
Using twin RCA-to-RCA leads, connect to the left and right ‘Audio  
Output’ of the tape machine to the TAPE 1 IN connectors for playback.  
Connect the left and right ‘Audio Input’ of the tape machine to the TAPE  
1 OUT connectors for recording.  
SAT to hear a source connected to Digital SAT.  
VCR & VIDEO 4 - Connections for the audio recording and playback  
to a VCR or other video recorder. Using twin RCA-to-RCA leads, connect  
to the left and right ‘Audio Out’ of the VCR to the VCR or VIDEO 4  
IN connectors for playback. Connect the left and right ‘Audio In’ of the  
VCR to the VCR or VIDEO 4 OUT connectors for recording. Using a  
single RCA-to-RCA (Video Composite) lead or S-Video lead, also connect  
the video output of the VCR to Video In for Video playback. Connect the  
Video Input of the VCR to Video Out of the NAD T742 receiver for  
recording of video signals. Refer also to the description of S-Video and  
Video Composite above in this section.  
CD INPUT - Input for CD player (analogue audio signal) or other line-level  
signal source. Use a twin RCA-to-RCA lead to connect the CD players left  
and right ‘Audio Outputs’ to this input.  
3. 5.1 CHANNEL INPUTS  
The coaxial Digital Input VCR (No. 5) is linked to the VCR input. Select  
VCR to hear a source connected to Digital Input VCR  
Inputs for the multi-channel audio signals from an external decoder, such  
as an MPEG decoder or a DVD player with integrated decoder. Use two  
twin RCA-to-RCA lead to connect the decoders front left and right  
“Audio Outputs” to the Front left and right inputs, and the decoders  
Surround left and right outputs to the Surround left and right inputs. Use  
a third twin RCA-to-RCA lead to connect the decoders subwoofer  
output to the Subwoofer input and the decoders Centre channel output  
to the Centre channel input. Make sure you to follow color coding of the  
plugs to ensure that both Centre and Subwoofer are connected correctly,  
for instance, use the red plugs at either end to connect the centre  
channel and the white plugs for the subwoofer channel.  
The coaxial Digital Input CD (No. 5) is linked to the CD input. Select  
CD to hear a source connected to Digital Input CD.  
5. DIGITAL AUDIO INPUTS  
The T742 has four digital audio inputs to allow for connection of DVD,  
CD, Satellite receiver or other digital sources:  
Digital AUDIO DVD and SAT allows for connection of a digital source  
with an Optical output. Use a cable terminated with a TOS Link connector.  
These Digital inputs are linked respectively to the VIDEO DVD/SAT inputs.  
Digital AUDIO VCR & CD allow for connection of a digital source with a  
Coaxial digital output. Use a cable with the right impedance, specifically  
designed for the transfer of digital signals. These digital inputs are linked  
respectively to VIDEO VCR and CD.

6. AUDIO PRE-OUTS / SUBWOOFER OUT  
NOTE  
This unit is designed to produce optimum sound quality when  
AUDIO PRE-OUTS - The NAD T742 receiver has five power amplifiers  
built-in to power all the speakers connected to it (Left, Right, Centre, Left  
Surround, Right Surround). It is also possible to use the T742 as a pre-  
amplifier to drive external power amplifiers. This way, you use all the  
control functions the T742 provides, such as input select, surround  
mode, volume, tone controls, etc., but the external power amplifier  
actually powers the speaker connected to it instead of the T742s  
integrated power amplifier for that channel.  
speakers with impedance within the set’s ranges are connected.  
Please check the following information and choose speakers with the  
correct impedance for the connections.  
FRONT SPEAKERS A: 8 ohms min. per speaker;  
CENTER SPEAKER B: 8 ohms min.  
SURROUND SPEAKERS: 8 ohms min. per speaker  
Connect the RCA-to-RCA leads from the Front left and Right, Centre,  
and/or Surround Left and Right Audio pre-out connectors to the external  
amplifiers. Connect speakers to the external amplifiers.  
CENTER SPEAKER - The terminal marked ‘C’ connects to the centre  
loudspeaker that is used when the T742 is operated in Dolby* Digital,  
DTS, Dolby Pro Logic, EARS surround sound mode or with the 5.1 Ch.  
input selected.  
NOTES  
Never connect the T742’s speaker outputs and the speaker outputs  
of an external amplifier to the same speakers. When headphones are  
inserted the signals from all audio pre-out outputs will be muted.  
Before making any connections, check that the T742 and the power  
amplifiers it will be connected to are switched off. With volume  
turned down to a low level, switch power on only after all  
connections have been made.  
Connect the centre speaker in the same way as described with front  
speakers above.  
SURROUND SPEAKERS - This connects the Surround loudspeakers that  
are used when the T742 is operated in Dolby Digital, DTS, Dolby Pro  
Logic, EARS Surround sound modes or with the 5.1 Ch. input selected.  
Connect the surround speakers in the same way as described with  
FRONT SPEAKERS above; connect the left surround speaker to the set of  
terminals marked ‘SLand the right surround speaker to the terminals  
marked ‘SR’.  
SUBWOOFER OUT - Unlike for the full range five channels as described  
above, there is no power amplifier built-in for an additional subwoofer.  
The Subwoofer pre-out allows for connection to a sub-bass speaker  
system with its own external or integrated power amplifier (“active”  
subwoofers).  
NOTE  
The Centre and/or Surround speakers must be selected as Large or  
Small in the Set-up menu “SPK SET” when speakers are connected to  
these outputs.  
7. MONITOR OUT  
Composite Video and S-Video outputs for connecting a TV or Video  
Monitor to view video sources connected to DVD to VIDEO 5. Usi  
ideo RCA-to-RCA lead, connect the “Video Line In” on the TV oVr  
monitor to the MONITOR OUT.  
9. SOFT CLIPPING  
When any amplifier is driven beyond its power output capabilities, a  
hard, distorted sound can be heard on very loud sounds. This is caused  
by the amplifier cutting off or ‘hard clipping’ the peaks of sound that it  
was not designed to reproduce. The NAD Soft Clipping circuit gently  
limits the output of the system to minimize audible distortion if the  
amplifier is overdriven.  
Note that an S-Video signal will also be available as a Video Composite  
signal on Monitor out, if the corresponding source is selected. The  
composite video input signals (No. 4; yellow sockets) will also be available  
as S-Video signal on the Monitor Out socket. If you use both S-Video and  
Video composite sources, you will only need to connect the S-Video  
Monitor Out to the television or projector.  
If your listening involves moderate power levels you may leave the Soft  
Clipping switch off. If you are likely to play at high levels that exceed the  
amplifiers power capability, then switch Soft Clipping on.  
8. SPEAKERS: FRONT, CENTER & SURROUND SPEAKERS  
FRONT SPEAKERS - Connect the right speaker to the terminals marked  
‘FR’ ensuring that the red terminal is connected to the ‘+’ terminal on  
your loudspeaker and the black terminal is connected to the  
loudspeakers -’ terminal. Connect the terminals marked “FL” to the left  
speaker in the same way.  
Always use heavy duty (16 gauge; 1.5mm or thicker) stranded wire to  
connect loudspeakers to your T742. Unscrew the speaker terminals  
plastic bushing. Insert the bare cable end into the hole of the terminal and  
then secure the cable by tightening down the terminals bushing (Fig. 6).  
To avoid any danger of bare metal from the speaker cables touching the  
back panel or another connector, ensure that there is only 1/2” (1.27cm)  
of bare cable and no loose strands of speaker wire.

completely. The NAD T742 receiver uses a memory back-up system to  
store surround sound trim settings and Preset station information for the  
tuner section. This information is retained for several weeks, even the  
unit is switched off completely or unplugged.  
11. AC POWER CORD  
After you have completed all connections to the amplifier, plug the AC  
line cord into a “live” wall socket.  
12. 12 VOLT TRIGGER OUT  
The 12V trigger output allows to remotely switch on or off ancillary  
equipment such as a CD player, power amplifier, etc. which are also  
equipped with a 12V trigger input. This can also be an AC outlet power  
strip equipped with a 12V trigger input. The 12V trigger output is  
activated whenever the T742 is switched to normal operational mode  
from Stand-by or Off.  
REMOTE CONTROL  
Power button - Press this button to switch the unit from operating to the  
Stand-by mode and vice versa. Press this button again to switch to unit on  
from Stand-by; the last selected source will be indicated in the display.  
NOTE  
For switching Stand-by/Power On of the external component, connect  
the 12V trigger output of the T742 to the remote components DC input  
jack. The plug required is a standard 3.5mm Mini-Jack plug (“mono”):  
The tip is the live or + connection, the shaft of the jack is the 12V trigger  
- or ground connection.  
Stand-by mode is indicated by the Stand-by indicator (No. 2) just over  
the green Power button on the front panel (No. 1).  
In Stand-by mode the T742 uses very little power. However, it is  
recommended that you switch the unit totally off if it is not going to be  
used for more than a couple of days. Switch off completely by pressing  
the Power button on the front panel (No. 1), all lights will extinguish.  
NOTES  
Check the specifications of the trigger input terminal on the other  
component to ensure it is compatible with the T742’s 12V trigger  
output.  
2. STAND-BY INDICATOR  
This green LED will light up when the receiver is switched On, but in  
Stand-by mode. Refer to section 1 in this chapter for more information.  
The T742’s 12V trigger output voltage is 12V DC. The total maximum  
current must not exceed 200mA. Typically, NAD 12V input triggers  
draw less then 10mA of current.  
3. DISPLAY  
NAD components equipped with 12V input triggers are fully  
compatible with the T742’s 12V trigger output.  
Before making any connections to any 12V trigger input or output,  
make sure all components are disconnected from the AC mains.  
The T742s FM tuner supports RDS PS and RDS RT. With stations carrying  
RDS information, “RDS” will light up in the display panel, and the  
stations RDS name is automatically displayed (RDS PS).  
Some radio stations, which support RDS, also transmit additional  
information, known as Radio Text (RDS RT). To view this information, use  
the Display button. With stations carrying RDS information, the DISPLAY  
button scrolls between three different display modes, each successive  
push of the button engages the next one of the three modes:  
Failure to observe the above may result in damage to the T742 or any  
ancillary components attached to it. If in doubt over the connections,  
installation and operation of the 12V trigger output consult your NAD  
dealer.  
a) In the default mode, the stations RDS name is displayed, Program  
Service (PS; normally the stations calling letters, BBC R3, for instance).  
b) From the default mode, press the button once to view Radio Text (RT).  
This can be additional information such as the presenters or  
programs name; what song is playing, etc. This text scrolls  
continuously over the 8 alphanumeric display segments. It takes a  
few seconds for the tuner to gather the RT information, so  
immediately after tuning to a station and selecting to view RT the  
display will indicate “NO TEXT” and default to the station name. If no  
RT information is available, the display will also show “NO TEXT” for  
three seconds before reverting to the default mode.  
c) Press the button from the display RT mode to display the station  
frequency. Press again to return to the default mode (a).  
When the DISPLAY button is pressed when tuned to a non-RDS station  
the display will show “NO NAME” for three seconds before reverting to  
the default display.

4. FM/AM  
8. DOWN / UP  
AND  
The FM/AM button switches the tuner section from the AM band to the  
FM band and vice-versa. The Display Panel shows the frequency of the  
tuned station and which band is selected. The FM tuning is in 0.05 MHz  
increments, AM tuning is in 9 kHz or 10kHz increments, depending on  
the version (9 kHz for the 230V version or 10 kHz for the 120V version).  
To change the AM increment tuning steps, press the FM/AM and CD  
buttons at the same time.  
The function of these buttons depends on the tuning mode selected with  
the Preset/Tune button (No. 7). The Preset/Tune button toggles between  
the two operation modes:  
a) Preset mode (indicated in the display area): Press the  
(down)  
button to scroll to a lower number Preset; press the  
(up) button  
to scroll to a higher Preset number. This is a “wrap-around” function,  
so that going from the highest number Preset, the tuner will go to  
the lowest Preset number or vice-versa when tuning either up or  
down.  
5. FM MUTE / MODE  
This button combines two functions; it switches the tuner from FM  
Stereo to Mono mode and disengages the muting circuitry at the same  
time. The muting circuit will mute the tuner in between radio stations  
when searching or tuning. This way the tuning noise is avoided.  
Very weak radio station signals however may be suppressed by the  
muting circuit. if such a very weak station is in stereo it will have a high  
level of background hiss. Switching to Mono and disengaging the  
muting circuit by depressing the FM MUTE/MODE button will allow the  
station to be heard and will cancel most or all of this background noise.  
b) Tune mode: Press the  
(down) or  
(up) button for more  
than 1/2 second to engage automatic tuning respectively up or down  
the frequency band. The tuner will search automatically for the first  
reasonably strong radio station, where it will stop. Press the Down/Up  
button again for 1/2 second to start searching again.  
NOTE  
Automatic tuning is available on both FM and AM.  
By briefly tapping the  
(down) or  
(up) buttons you can engage  
In normal operation the mute circuit is engaged, the display indicates  
“FM MUTE”. Press the FM Mute/Mode button to disengage the muting  
circuit and switch from stereo to mono reception. “FM MUTE” will  
extinguish in the display. Also, “FM STEREO” will extinguish if a stereo  
broadcast was received. Press the FM Mute/Mode switch again to return  
to Auto Stereo FM operation.  
manual tuning respectively down or up the frequency band for precise  
tuning to a specific frequency. With each successive tap of the keys, the  
tuner will take 0.05 MHz steps on FM so you can accurately tune into the  
desired frequency.  
This tuning mode can also be useful when trying to receive a radio  
station which is too weak for the auto search mode. When tuned  
In combination with the MEMORY button (No. 6) and DOWN/UP buttons  
(No. 8) a preset number can be emptied. (Refer to the separate chapter  
“Storing and Recalling Presets” for more information.)

TUNED  
” will light up in the display.  
Very weak radio station signals however may be suppressed by the  
muting circuit. If such a very weak station is in stereo it will have a high  
level of background hiss. Switching to Mono and disengaging the  
muting circuit by depressing the FM MUTE/MODE button (No. 5) will  
allow the station to be heard and will cancel most or all of this  
background noise.  
6. MEMORY  
The Memory button is used to store stations into the Preset Memory (1-  
30 Presets on FM, 1-10 Presets on AM), used in conjunction with the  
Down/Up (No. 8) buttons on the front panel. In combination with the FM  
MUTE/MODE button (No. 5) and DOWN/UP buttons (No. 8) a preset  
number can be emptied. When Memory is active, the Preset number  
flashes and the red “MEMORY” indicator is shown in the Display Panel.  
If no other button is pressed within 10 seconds “MEMORY” will stop  
flashing and the receiver will default to its previous state.

7. PRESET / TUNE  
In the default function, this control acts as a Volume control, adjusting  
the overall loudness of the signals being fed to the loudspeakers and  
headphones. Unlike conventional controls, the T742s volume control  
doesn’t have a start or end position. Volume can also be adjusted from  
the remote control handset using the Master Volume Up or Down  
buttons. The Volume control does not affect recordings made using the  
Tape, VCR and Video 4 outputs but will affect the signal going to the  
Pre-amp output (Audio Pre Out). The volume level is indicated in the  
display panel when it is being adjusted. After three seconds the display  
defaults to its previous status. Volume setting can range from  
' to +18dB.  
The Preset/Tune button toggles between the Preset and Tune mode.  
When Preset mode is selected, “PRESET” lights up in the display area.  
Up to 40 Presets, either AM (10 Presets) or FM (30 Presets), can be stored.  
Refer also to separate chapter “Storing and Recalling Presets” for more  
information.  
On the remote control handset, press the Mute button to temporarily  
switch off the sound to the speakers and headphones. Mute mode is  
indicated by “MUTING” flashing in red in the display area. Press Mute  
again to restore sound. Mute does not affect recordings made using the  
Tape,VCR and Video 4 outputs but will affect the signal going to the  
Pre-amp output (Audio Pre Out) and headphones.

VIDEO OUTPUT - The video signal available on the S-Video and Video  
Composite outputs is dependent on the selected video input (DVD,  
SAT, VCR, VIDEO-4, VIDEO-5). However, when one of the  
audio-only sources is selected (FM, AM, CD, Tape Monitor or Ext. 5.1) the  
last selected video signal from one of the video inputs will be present on  
these outputs. This way you can watch a DVD player or video whilst  
listening to the CD player.  
The control is also used to adjust various set-up settings and levels for the  
T742. In conjunction with the SETUP button (No. 17) the speakers size  
and delay can be adjusted; in conjunction with the Tone Control button  
(No. 18) the Bass and Treble levels can be adjusted. Refer also to sections  
“SETUP” and “Tone controls” in this chapter.  
11. HEADPHONE SOCKET & VIDEO 5 INPUT  
HEADPHONE SOCKET - A 1/4” stereo jack socket is supplied for  
headphone listening and will work with conventional headphones of any  
impedance. The volume and tone controls are operative for headphone  
listening. Use a suitable adapter to connect headphones with other types  
of connectors such as 3.5mm stereo ‘personal stereo’ jack plugs.  
The display indicates which video signal is routed to the MONITOR OUT  
sockets (No. 7 on back panel).  
13. CD  
Selects the CD as the active input. The Digital Input CD is linked to the CD  
input (marked CD on the back panel, No 5) Digital source with a  
coaxial (RCA jack) dgital output. Whenever the corresponding  
digital input is activated, Digital Input CD will also be selected,  
in the display the " DIGITAL" indicator will start to blink. If a  
digital audio signal is detected, the "DIGITAL " indicator will stop blinking  
and remain lit. If no digital audio signal is detected, the " DIGITAL"  
indicator will cease blinking and extinguish.  
Inserting a headphone will automatically turn off all speakers and signals  
from the Audio Pre-Out sockets and switches the T742 to the stereo  
mode. Surround sound modes are not available when headphones are  
inserted in the headphone socket.  
The sound from the EXT. 5.1 CH input is not available on the headphones  
socket.  
NOTES  
In the VFL display “Speaker settings”, be sure to have selected and  
adjusted a preset with “MAIN SPEAKERS” set to “LARGE”. If set to  
“SMALL”, bass response will be limited.  
14. TAPE MONITOR  
Listening at high levels can damage your hearing.  
Selects the output from a tape recorder when playing back tapes or  
monitoring recordings being made through the Tape sockets. Press the  
TAPE MONITOR button once to select it and again to return to the  
normal input selection.  
VIDEO 5 INPUT - For easy and temporary connection you can connect a  
camcorder (playback only) or video game console. If the game console or  
camcorder is mono, connect the audio lead to the R (Right) audio socket.  
The Tape Monitor function does not override the current input selection.  
For example, if the CD is the active input when Tape Monitor is selected,  
the CD signal will continue to be selected and is sent to the Tape Out,  
VCR and Video 4 Out sockets. But it is the sound from recorder  
connected to Tape that will be heard on the loudspeakers when the TAPE  
MONITOR function is selected. When Tape Monitor is selected, “TAPE  
MONITOR” will remain lit until Tape Monitor is disengaged again.  
12. AUDIO & VIDEO INPUT SELECTORS  
DVD & SAT - DVD & SAT selects the signal from a TV/Satellite/Cable  
receiver or DVD player connected to DVD or SAT as the active  
input. “DVD” or "SAT" is shown in the Display Panel when selected.  
The Digital Input DVD or SAT is linked to the DVD or SAT input (marked  
DVD & SAT on back panel; No. 5). Digital Input DVD or SAT allow for

The Dolby Digital signal allows for several channel configurations. DTS  
digital surround is an Encode/Decode system that currently delivers six  
discrete channels (5.1) of “Master-Quality” up to 24-bit audio. Dolby Pro  
Logic decodes the centre and surround sound signals embedded in stereo  
movie sound tracks from e.g. video, Laser Disc or TV. To decode correctly,  
the source must be a Dolby Surround or Dolby Stereo soundtrack.  
In the EARS (Enhanced Ambiance Retrieval System) Surround Mode, a  
realistic level of ambience of surround sound is added to a normal stereo  
source such as a CD or FM radio.  
Dolby Pro Logic is the latest decoder for Dolby Surround. It enhances  
the spatiality and directionality of those existing Dolby Surrond programs.  
Dolby Pro Logic Movie is actually an improvement over Dolby Pro Logic  
by giving an extra stereo surround channel and without a frequency filter  
on the speaker signal.  
DIMENSION (Dolby Pro Logic II Music Mode only  
This allows teh gradual adjustment of the sound field either towards  
the front or the rear. This can help achieve the desired balance from all the  
speakers with certain recordings that may contain either too much or  
too little spatial effect. Step '0' is the recommended setting of which has  
no effect on the sound. Steps " +1" , " +2" , and " +3" gradually  
move the sound forward, and Steps " -1" , " -2" , and " -3" moves  
the sound towards the surrounds.  
Dolby Pro Logic Music is especially for music but not movies.  
Dolby Pro Logic Panorama is a mode for extention of teh front stereo  
image to include the surround speakers for an exciting  
" wraparound" effect with side wall imaging.  
Dolby Pro Logic Matrix is mor or less the same as Music mode,

17. SET UP  
This button is used to configure the T742 to match with the specific  
speakers in your system. This setup procedure should be done when you  
first install your system, and subsequently when new or different  
speakers are attached, or when the speaker positions are changed.  
Refer to section SETTING UP A SURROUND SYSTEM below for more  
detailed information on making these adjustments.  
The SET UP facility uses a “menu” system that is 3 layers deep to  
accomplish the speaker setup. The Front Panel display will give you  
feedback on where you are in the menu system at any given moment.  
By first pressing the SET UP button and then turning the VOLUME/SETUP  
knob all menu items can be accessed.  
18. TONE CONTROLS  
This button is used to adjust Bass and Treble response to suit personal  
taste, or to compensate for less than optimal program sources. Each  
press of the TONE CONTROLS button cycles through BASS > TREB  
> and back to the previously selected input. Adjustment of Bass and  
Treble response is accomplished by turning the VOLUME/SET UP knob.  
Adjustment can be made in 2 dB increments up to +/- 10 dB. After a 5  
sec default time, if no adjustment is made, the T742 will automatically  
exit the TONE CONTROLS mode and return to the last selected input.  
CENTRE WIDTH (Dolby Pro Logic II Music Mode only  
This allows centre-channel sounds to be positioned between the centre  
speaker and the left/right speakers over a range of eight steps. Step '3' uses  
a combination of all three front speakers to give the best vocal imaging  
and most seamless soundstage and is recommended for most recordings.  
Step '0' places all centre sound in the centre speaker. Step '7'  
places all centre sound equally in the left/right speakers, as in  
conventional stereo.

STORING AND RECALLING PRESETS  
TO STORE A PRESET  
DELETING A STORED PRESET  
You can empty a Preset by deleting the stored information:  
Tune to the radio station you wish to enter into a Preset (refer to  
chapter “Front Panel Controls”; section 8). If the station is  
transmitting RDS information, the RDS indicator will light up and  
station initials will be shown in the Display Panel. If a non-RDS station  
is found, then just the frequency will be shown.  
Press MEMORY button (No. 6).  
Press DOWN/UP buttons (No. 8) to select the preset number to be  
deleted.  
Press the FM MUTE/MODE button (No. 5). The Preset will then be  
deleted and ‘—’ appears as the Preset number.  
To store that station as a Preset, press MEMORY (No. 6). “MEMORY”  
and the preset section in the display panel will start to flash. If no  
other button is pressed within 10 seconds, “MEMORY” will stop to  
flash and the receiver will default to its previous state.  
You can also store a new station into a used Preset, by simply going  
through the Preset storing process and placing a new station over the  
existing one.  
Press either the  
(down) or  
(up) button to select which  
Preset number you wish to assign to the station (from 1 to 30 on FM  
and 1 to 10 on AM), shown as a flashing number in the Display Panel,  
and then press MEMORY (No. 6) again. The Memory light in the  
Display Panel will go out and the station is now stored in your NAD  
T742s memory.  
REMOTE CONTROL AVR 2 (FIGURE 3.)  
The T742 is supplied with the NAD AVR 2 Remote Control. Apart from  
all the primary operating functions, the AVR 2 Remote Control handset  
also gives access to functions not available on the front panel of the  
T742. It also has additional controls to remotely operate NAD T550, L55,  
T531 and T571 DVD Players. The function of the buttons will change  
between the T742 Receiver and the NAD DVD Player depending on the  
position of the RCVR/DVD switch (See 25 below). Shared buttons  
(buttons that function with the switch in either position) have the  
receiver function printed on the button itself, with the secondary DVD  
function printed on the body of the remote handset  
To exit the Memory mode without storing a station, leave all the tuner  
controls untouched; the Memory mode will automatically cancel itself  
after 10 seconds. The Memory Presets have a memory back-up, so they  
will remain stored for several weeks even if the Receiver is switched off or  
unplugged from the mains supply.  
NOTE  
You can enter a new station into an unused Preset or over-write an  
existing programmed Memory Preset. By doing this you will replace  
the radio station previously held on that Preset number.  
Alkaline batteries are recommended for maximum operating life. Two  
AAA (R 03) batteries should be fitted in the battery compartment at the  
rear of the Remote Control handset. When replacing batteries, check

6. DYNAMIC RANGE / NEXT DISC  
The DYN. R button, which can be used only in combination with a Dolby  
Digital source, incrementally reduces the audio tracks dynamic range in  
four steps (100%, 75%, 50% and 25%) to allow for comfortable listening  
under a variety of conditions. The normal or default position is 100%.  
9. VOLUME / ARROW  
Volume + or - respectively increases or decreases the volume setting for  
all speakers. The display panel will indicate the level set. The Volume  
control does not affect recordings made using the Tape and Video, or

both the DVD player and DVD Video discs. Refer to the NAD DVD player  
Owners Manual for more detailed information on this function.  
NOTE  
10. MUTE / ENTER  
Although we usually prefer to reproduce a source’s full dynamic  
range (the difference between very loud and very soft sounds), it may  
occasionally be desirable to reduce the dynamic range. For example,  
when playing a movie late at night, loud explosions might wake  
sleeping family members. Simply turning the volume control down  
would probably make a whisper in the next scene inaudible. The  
DYN. R button solves this dilemma by progressively lowering the  
volume of loud peaks while increasing the level of softer sounds.  
Press the MUTE button to temporarily switch off the sound to the  
speakers and headphones. Mute mode is indicated by “MUTING”  
flashing in red in the display area. Press MUTE again to restore sound.  
Mute does not affect recordings made using the Tape out-puts but will  
affect the signal going to the Audio Pre-outs and headphones.  
NOTE  
When the unit is in mute mode, any adjustment of the VOLUME  
CONTROL on the front panel (No.10) or Remote Control (No. 9) will  
release the muting, i.e. the original volume level will be resumed.  
7. TEST / TITLE  
Pressing the TEST button, engages the Test signal generator to allow for  
adjustment of all speaker levels, so that each channel can be adjusted for  
equal loudness at your listening position. The test signal scrolls  
automatically with 2 second intervals from Front Left, Centre, Front Right,  
Rear Right, Rear Left, to subwoofer in continuous cycles. If an adjustment  
in setting is made for one of the speakers, scrolling will stop until  
2 seconds after the adjustment was made. The display panel shows  
which speaker is being fed with the test signal. Use the VOLUME +/-  
buttons to respectively increase or decrease the level for the current  
speaker. Press the TEST button again to leave or cancel the Test mode,  
any changes will be memorized automatically.  
11. TUNE UP / TUNE DOWN AND ARROW

DVD Players) and DVD2 (codes for T531 and T571 DVD Players).  
SETTING UP THE SURROUND SYSTEM  
In DVD mode this buttons function is determined by the individual DVD  
disc title being played. Refer to the NAD DVD Player Owners Manual for  
more detailed information on this function.  
To obtain the best results in any of the Surround Modes it is important  
that the T742 is carefully set up. The Dolby Surround system requires  
that you specify the parameters of your speaker setup so it can properly  
direct the decoded surround sound signal in the correct proportion to  
create the most accurate theatrical effect. Dolby also allows for the  
redirection of bass frequencies to the most appropriate speaker(s). This  
is also known as “bass management”.

UP button again to change the size. Each press of the SET UP button will  
change the setting for that speaker:  
Many film soundtracks rely heavily on very low frequency sound effects  
which are difficult for normal or smaller hi-fi speakers to reproduce. To  
faithfully reproduce these low frequencies you can use a specially  
designed low frequency loudspeaker with its own built-in amplifier  
(“active subwoofer”). Because it is difficult to hear which direction very  
low frequencies are coming from, you only normally need one sub-  
woofer and this can be placed virtually anywhere in the room. The  
Subwoofer output of the T742 is designed specifically to drive a  
subwoofer system.  
REAR (Surround Speakers) can be set to LAR, SMA or OFF.  
Now rotate the VOLUME/SETUP knob until SUB ON (current setting for  
the Subwoofer) appears in the display window. Press the SET UP button  
again to change the setting. Each press of the SET UP button will change  
the setting for that speaker:  
SUB (subwoofer) can be set to ON, OFF.  
Dolby Digital uses a dedicated Low Frequency Effects (LFE) channel. If a  
subwoofer has been selected, the LFE channel will be fed to the sub-  
woofer output. If no subwoofer is selected the LFE channel is redirected  
to the front left and right speakers.  
Now rotate the VOLUME/SETUP knob until EXIT appears in the display  
window. Press the SET UP button again to exit SPEAKER SETTING MENU.  
Press the SET UP button again to exit the SET UP MENU. Your speaker  
settings are now complete. If in the future you add or change speakers,  
this setup procedure should be repeated.  
CHANNEL DELAYS  
For the best surround sound performance it is important that sound from  
all speakers reach the listeners ears at the same time. Because the  
surround/ rear speakers are usually closer to the listener than the front  
speakers, there is tendency for the ear to localize sounds to the rear,  
because the ear takes most notice of the sounds that arrive at the head  
first. Similarly, the centre speaker is often closer to the listener than the  
front left and right speakers. To compensate for this, the T742 can  
slightly delay the audio sent to the centre and rear (closer) speakers. In  
this way, when playing Dolby Digital or Dolby Pro logic soundtracks, the  
sound from all speakers arrives uniformly at the listening position as  
intended by the films producer.  
TIPS ON WHICH SPEAKER SETTINGS TO USE  
The four modes available to the T742s setup are: LARGE or SMALL and  
ON or OFF.  
The LARGE mode is used when the speaker is full range and capable of  
reproducing the entire audible frequency spectrum 20Hz to 20kHz. The  
SMALL mode is used when the speaker is not capable of reproducing the  
deepest bass portion of the audio frequency 20Hz to 100Hz.  
The ON mode is used when the speaker is active and receives the audio  
information intended. The OFF mode is used when the speaker is  
inactive. Audio signals intended for speakers set to the OFF position are  
redirected to the main speakers.  
Each millisecond corresponds approximately with 1 foot or 30.5  
centimeters.  
NOTE  
Using a separate centre channel speaker will allow the dialogue to cut  
through even the biggest sound effects and musical scores. Having the  
sound spread across three front speakers also stabilizes the stereo image,  
making the usable listening area much bigger. For best results, you  
should consider using a centre speaker. Ideally it should be the same type  
as the left and right speakers.  
The channel delay option is not available in DTS surround mode.  
TO ADJUST DELAY SETTINGS  
When Front Panel Display shows DELAY, pressing the SET UP button on  
front panel again (second press) will enter the DELAY SETTING menu.  
Rotate VOLUME/SETUP knob to cycle between CENT > REAR > EXIT.  
Installing surround speakers will greatly enhance the surround experience  
as these add considerably to the overall “ambience”.  
First stop at CEN 0mS (current delay setting for Centre Speaker). Press  
the SET UP button again to change the delay setting. Rotate the  
VOLUME/SETUP knob to change centre delay adjustment in 1mS  
increments from 0mS to 5mS. Press SET UP button again to exit Centre  
delay adjustment.  
Dolby Pro Logic encoded material is deliberately limited in dynamic range  
and frequency bandwidth for the surround channel and thus only  
requires speakers of far lesser specification compared to the front  
channels. Dolby Digital however is a full range system, with two  
independent surround channels and with dynamics equal to that of the  
front channels. For this reason it is advisable to choose loudspeakers  
which are similar in power handling and performance capability to those  
of the front channels. For best results, the Surround loudspeakers should  
not beam the sound directly at the listener. One way of achieving this is  
to use ‘dipole’ Surround speakers which aim the sound down the walls  
rather than directly into the room.  
Now rotate the VOLUME/SETUP knob until REAR 0mS (current delay setting  
for Surround Speakers) appears in the display window. Press the SET UP  
button again to change the delay setting. Rotate the VOLUME/SETUP knob  
to change centre delay adjustment in 1mS increments from 0mS to 15mS  
in Dolby Digital mode, or 15mS to 30mS in Dolby ProLogic mode. Press SET  
UP button again to exit Rear delay adjustment.  
Now rotate the VOLUME/SETUP knob until EXIT appears in the display  
window. Press the SET UP button again to exit DELAY SETTING MENU.  
Press the SET UP button again to exit SET UP MENU. Your speaker  
settings are now complete. If in the future you add, change, or move  
speakers, this setup procedure should be repeated.

TIPS FOR SETTING DELAY  
The Channel Balance for each speaker can be adjusted in 1dB  
increments. Continue to calibrate the level for each speaker until equal  
loudness is achieved at your listening position. A more accurate  
adjustment can be made using a sound level meter, if available. Set the  
meter to “Slow” and “C-weighted” modes and re-check the settings  
with the meter placed in several different positions in the general  
listening area.  
Measure the distance from the listening position to the centre speaker  
(dC) and to one of the front speakers (dFL or dFR). Subtract the centre  
channel distance from the front L or R channel distance. For example, if  
the front speakers are 12 feet (3.7 m) from the listening position and the  
centre speaker is 10 feet (3.0 m), the difference is 2 feet (0.6 m). For this  
example the centre channel delay is set to 2 milliseconds or ms.  
The T742 can delay the centre channel output up to 5 milliseconds and  
thus compensates for centre channel speakers that are up to 5 feet  
(1.5m) closer to the listening position than the front left and right  
speakers.  
Press the TEST button again to leave or cancel the Test mode, any  
changes will be memorized automatically.  
Select the channel for which you wish to adjust and set the level so that it  
matches the other speakers. For best results it is best to start with the Left  
channel set at 0dB and to match the other speakers to it. Normally, if the  
Right speaker is located at the same distance from the listening position to  
the Left speaker it should be set at the same level as the Left speaker.  
NOTES  
In rare system setups, the centre channel speaker is actually further  
away than the front left and right speakers. In these cases, set the  
centre channel delay to 0mS. The centre channel delay time  
adjustment is only available in Dolby Digital surround mode.  
NOTE  
If no level adjustments were made, press TEST again to return to the  
selected source. Any changes in the Channel Balance Setting, under  
the test mode, will be memorized automatically.  
Measure the distance from the listening position to either the left or right  
rear speaker (dLS or dRS). Subtract the rear speaker distance from the  
front speaker distance (dFL or dFR). The resulting distance is equivalent to  
the delay in milliseconds for the rear delay setting. For example, if your  
rear speaker distance is 6 feet (1.8 m) and the front distance is 12 feet  
(3.7 m), the correct rear channel delay setting is 6 milliseconds. Again, set  
the rear channel delay to 0mS if the rear channels are further from the  
listening position than the front speakers.  
The Delay time for the Surround speakers also needs to be correctly set  
for your normal listening position. Refer to the section “Channel Delay”  
in this chapter for more information.  
In Dolby Digital surround mode, the rear channel delay time can be set  
from 0ms to 15ms with 1ms increments. In Dolby Pro logic surround mode,  
the rear channel delay time can be set from 15ms to 30ms and 1ms per  
step. In DTS surround mode, the channel delay time cannot be adjusted.  
LEVEL SETTING (CHANNEL BALANCE)  
The output levels of each of the speakers connected to the T742 may  
need to be adjusted so that there is an even balance of sound from all  
the speakers in the system. If, for instance, the relative volume level to  
the Left and Right speakers and the centre speaker is set too low, most  
of dialogue may be difficult to follow. If, on the other hand it is set too  
loud, the over-all balance will sound unnatural.  
To adjust the channel balance, the T742 is equipped with a TEST button  
(No. 7) on the Remote Control to help assess the loudness levels of each  
speaker. Before adjusting the channel balance level, make sure the  
master volume is turned down to a normal listening level.  
Pressing the TEST button engages the Test signal generator to allow for  
adjustment of all speaker levels, so that each channel can be adjusted for  
equal loudness at your listening position. The test signal scrolls  
automatically with 2 second intervals from Left, Centre, Right, Rear Right,  
Rear Left, to sub-woofer in continuous cycles. If an adjustment in set-ting  
is made for one of the speakers, scrolling will stop until 2 seconds after the  
adjustment was made. The display panel shows which speaker is being fed  
with the test signal. Use the VOLUME +/- buttons on the Remote Control  
to respectively increase or decrease the level for the current speaker.  
NOTE  
There is no output in the Subwoofer during noise sequencer operation;  
therefore it is difficult to adjust the level in test mode. The Subwoofer  
level can be adjusted in the setup menu with musical input.
