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 al 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 T742 integrated power amplifier for that channel 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. NOTES + Never connect the 1742‘ 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 tumed down to a low level, switch power on only after all connections have been made. SUBWOOFER OUT - Unlike for the full range five channels as described above, there is no power amplifier bult-in for an additional subwoofer The Subwoofer pre-out allows for connection to à sub-bass speaker system with its own external or integrated power amplifier (’active” subwoofers).

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 heawy 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 NOTE This unit is designed to produce optimum sound quality when speakers with impedance within the sets 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 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. Connect the centre speaker in the same way as described with front speakers above SURROUND SPEAKERS - This connects the Surround loucspeakers 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 ‘SL’ and the right surround speaker to the_terminals marked *SR' 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.

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 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.

This input is connected to an output of an infrared receiver. This This remote control input is usually used in custom installations. Ask your dealer or custom isnstaller for further details.

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 à CD player, power amplifier, etc. which are also equipped with à 12V trigger input. This can also be an AC outlet power tip equipped with à 12V trigger input. The 12V trigger output is activated whenever the T742 is switched to normal operational mode from Stand-by or Off. 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 à standard 3.5mm Mini-lack plug (“mono”): The tip is the live or + connection, the shaft of the jack is the 12V trigger - or ground connection. NOTES + Check the specifications of the trigger input terminal on the other component to ensure it is compatible with the T742'5 12V trigger output. + The T7425 12Vtrigger output voltage is 12V DC. The total maximum current must not exceed 200mA. Tpicall, NAD 12V input triggers draw less then 10mA of current. + NAD components equipped with 12V input triggers are fuly compatible with the 17425 12V trigger output. Before making any connections to any 12V trigger input or output, make sure all components are disconnected from the AC mains. Failure to observe the above may result in damage to the T742 or any andillany components attached to it. If in doubt over the connections, installation and operation of the 12V trigger output consult your NAD dealer.

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 T7425 FM tuner supports RDS PS and RDS RT. With stations carrying RDS information, "RDS" will light up in the display panel, and the station's 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: a) In the default mode, the station's RDS name is displayed, Program Service (PS; normally the station‘ 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. d 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 à non-RDS station the display will show “NO NAME" for three seconds before reverting to the default display.

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.

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 à 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 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 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.)

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 Refer to the separate chapter “Storing and recallng Presets” for more information

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

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 W (down) button to scroll to a lower number Preset; press the À (up) button to scroll to a higher Preset number. This is à “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 b) Tune mode: Press the W (down) or À (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 tappingthe W (down)or À (up) buttons you can engage 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 à radio station which is too weak for the auto search mode. When tuned accurately to a station, “ > TUNED < will light up in the display. Very weak radio station signals however may be suppressed by the muting circuit. f such a very weak station is in stereo it will have à 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 wil cancel most or all of this background noise Refer to the separate chapter “Storing and Recalling Presets" for more information:

Vacuum Fluorescent Display. The display area will show all vital information when the unit is operational.

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 T742' 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. 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

If no digital audio signal is detected, “DVD” or “SAT* indicator will cease blinking and extinguish VCR & VIDEO 4 - VCR & 4 select the signal from à TVSatellte/Cable receiver, DVD player or VCR connected to VCR or VIDEO 4 as the active input. "VCR" or “VIDEO-4" is shown in the Display Panel when selected. The VCR & 4 inputs also have video and analogue audio outputs specificall for recording video devices The Digital Input VCR is linked to_the VCR input (marked Digital In on back panel; No. 5). Digital Input VCR allows for connection of à digital source with a Coaxial (RCA Jack) digital output. Wheneer the corresponding digital input is activated, Digital Input VCR will also be selected; in the display the “VCR" indicator will start to blink. If à digital audio signal is detected, the “VCR" indicator will stop blinking and remain lit. If no digital audio signal is detected, “VCR" indicator will cease blinking and extinguish

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-S). However, when one of the audio-only sources is selected (FM, AM, CD, Tape Monitor or Ext. 5.1) the lest selected video signal from one of the video inputs will be present on these outputs. This way you can watch à DVD player or video whilst listening to the CD player. The display indicates which video signal is routed to the MONITOR OUT sockets (No. 7 on back panel).

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 à 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 wil stop blinking and remain lit. If no digital audio signal is detected, the "DIGITAL" indicator will cease blinking and extinguish.

Press the TAPE MONITOR button once to select it and again to return to the normal input selection: 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

Selects the multi-channel output signal from the DVD player or external decoder source (such as MPEG, for instance) connected to the 5.1 Ch Input as the active input. The 5.1 Input is à direct pass through with only the volume control in the circuit. Bass management settings and tone controls are not available on this input. NOTE No Ext. 5.1 audio signal is available from headphones socket, the Tape, VCR and Video 4 out-puts when the Ext. 5.1. input has been selected.

With the Surround Mode buttons the available surround sound modes can be selected. The selected Surround mode is permanentiy indicated in the display Area. The Surround Mode buttons scroll through the available surround sound modes: With any of the Digital nputs DVD, SAT, VCR or CD (press DVD, SAT, VCR or CD respectively to select), the T742 automatically recognizes if the selected source caries à Dolby Digital" or DTSTM signal. When no Dolby Digital or DTS signal is available, the Surround Mode buttons scrolls through the other available surround sound modes ENHANCED STEREO > PLII MOVIE > PLII MUSIC > PLII PAN > PLII MATRIX > PROLOGIC > EARS > back to ENHANCED STEREO With either Dolby Digital or DTS surround mode engaged, the Dolby Pro Logic and Ears surround modes cannot be selected. Dolby Digital and DTS has six independent channels available in total: Left, Centre. Right, Surround left, Surround Right and an “Effects Channel” (Subwoofer) The Dolby Digital signal allows for several channel configurations. DTS digital suround 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 correct, the source must be à Dolby Surround or Dolby Stereo soundtrack. In the EARS (Enhanced Ambiance Retrieval System) Surround Mode, à realistic level of ambience of surround sound is added to à normal stereo source such as à CD or FM radio. Dolby Pro Logic is the latest decoder for Dolby Surround. It enhances the spatialty and directionaliy of those existing Dolby Surrond programs. Dolby Pro Logic Movie is actually an improvement over Dolby Pro Logic by ghing an extra stereo surround channel and without a frequency filter on the speaker signal. 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, ecxept mono signals are processed to seem "wider" In the Enhanced Stereo Mode, the T742 delivers Right & Left channels to Surround Left & Surround Right and (-6 dB) to the Centre Channels

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.

The DYN. R button, which can be used only in combination with à Dolby Digital source, incrementally reduces the audio tracks dynamic range in four steps (100%, 75%, 50% and 25%) to allow for comfortable listening under à variety of conditions. The normal or default position is 100%. To adjust the dynamic range, each consecutive press of the DYN. R button will reduce the value in 25% increments, as shown in the alpha- numeric display section NEXT DISC functions with a DVD Changer (NAD T571) to select the next disc loaded in the carousel. Each press of the button advances by one disc. Refer to the NAD DVD player Owner's Manual for more detailed information on this function. NOTE Although we usually prefer to reproduce à sources full dynamic range (the difference between very loud and very soft soundé), it may occasionally be desirable to reduce the dynamic range. For example. when playing à movie late at night, loud explosions might wake sleeping family members. Simply turning the volume control down would probably make à whisper in the next scene inaudible. The DYN. R button soles this dilemma by progressively lowering the volume of loud peaks while increasing the level of softer sounds

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. f an adjustment in setting is made for one of the speakers, scrolling will stop until 2 seconds after the adjustment was made.

SETTING UP THE SURROUND SYSTEM

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” The setup procedure is broken down in three sections: 1 Speaker Settings (by Front Panel controls)

2. Channel Delays (by Front Panel controls)

3 Level Settings for correct Channel Balance (by Remote Control handset)

SPEAKER SETTING OPTIONS

EXT TO ACCESS THE SPEAKER AND DELAY SETTING ADJUSTMENTS Pressing the front panel SET UP button (fist press) the display will show SPK SET. Rotating the VOLUME/SETUP knob alternately cycles the setting between SPK SET, DELAY , EXIT, and then “wraps” back to SPK SET. Speaker Settings - First you need to indicate which speakers are connected to your T742. Besides the Main speakers (Left & Right), these can include à Centre, two Surround Speakers and à Subwoofer. To Adjust Speaker Settings - When Front Panel Display shows SPK SET, pressing the SET UP button on front panel again (second press) wi enter the SPEAKER SETTING menu. Rotate VOLUME/SETUP knob to cycle between MAIN > CEN > REAR > SUB > EXIT. First stop at MAIN and display shows LAR (current setting for FRONT or MAIN speakers). Press the SET UP button again to change the size. Each press of the SET UP button will change the setting for that speaker: MAIN (Front Speakers) can be selected as LRG or SML Now rotate the VOLUME/SETUP knob until CEN LAR (current setting for the CENTER speaker) appears in the display window. Press the SET UP button again to change the size. Each press of the SET UP button will change the setting for that speaker: CEN (Centre Speaker) can be selected as LAR, SMA or OFF.

Now rotate the VOLUME/SETUP knob until REAR LAR (current setting for the SURROUND speakers) appears in the display window. Press the SET UP button again to change the size. Each press of the SET UP button will change the setting for that speaker: REAR (Surround Speakers) can be set to LAR, SMA or OFF. Now rotate the VOLUME/SETUP knob until SUB ON (eurent 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 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 TIPS ON WHICH SPEAKER SETTINGS TO USE The four modes available to the T742' 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, Using à separate centre channel speaker wi allow the dialogue to cut through even the biggest sound effects and musical scores. Having the sound spread across three front speakers also stabilzes the stereo image, making the usable listening area much bigger. For best results, you should consider using a centre speaker. Ideall it should be the same type as the left and right speakers Installing surround speakers will greatly enhance the surround experience as these add considerably to the overall “ambience” 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 à 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. 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 à 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 specficaly to drive à subwoofer system. Dolby Digital uses à dedicated Low Frequency Effects (LFE) channel. If à 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. 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 slightiy 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. Each milisecond cormesponds approximately with 1 foot or 30.5 centimeters. NOTE 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. First stop at CEN OmS (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 OmS to 5mS.. Press SET UP button again to exit Centre delay adjustment. Now rotate the VOLUME/SETUP knob until REAR OmS (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 OmS 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

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 miliseconds or ms. The 1742 can delay the centre channel output up to 5 millseconds and thus compensates for centre channel speakers that are up to 5 feet (15m) doser to the listening position than the front left and right speakers. 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 OmS. The centre channel delay time adjustment is only available in Dolby Digital surround mode. 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 OmS if the rear channels are further from the listening position than the front speakers. In Dolby Digital surround mode, the rear channel delay time can be set from Oms 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 à 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 à 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 scrols 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, scroling wil 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 difficult to adjust the level in test mode. The Subwoofer level can be adjusted in the setup menu with musical input.

The Channel Balance for each speaker can be adjusted in 1d8 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 Press the TEST button again to leave or cancel the Test mode, any changes will be memorized automaticalh 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 OdB 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 NOTE no level adjustments were made, press TEST again to retum to the selected source. Any changes in the Channel Balance Setting, under the test mode, will be memorized automatically. The Delay time for the Surround speakers also needs to be correctiy set for your normal listening position. Refer to the section “Channel Delay” in this chapter for more information.
