NAD T743 listening modes is missing. Receiver need to have 9 listening modes, but I can`t see it nowhere. Its shows only stereo mode. Speakers settings, input signals is not at fault. All other functions are working, but when pushing surround mode button it nothing happens.

Some info from the manual:
The Dolby Digital and DTS listening modes can only be selected if your Blu-ray Disc/DVD player is connected to
the AV receiver with a digital audio connection (coaxial,
optical, or HDMI).
• The listening modes you can select depends on the format of the input signal. To check the format, see "Displaying Source Information"
• While a pair of headphones is connected, you can select the following listening modes: Mono, Direct, and Stereo.
• While Speakers A and B are on, you can select only the
Direct, Stereo, Mono, or T-D (Theater-Dimensional) listening mode.

Plus this Bit of info on the speakers A and B buttons.
While Speakers B is on, channels are reduced to 2.1 in the
main room.

If you can access the speaker configuration it should provide test tones to each speaker. If you can't the speaker A and B are not set right.
If you have pressed the stereo or mono button no sound will be heard except from the front two or the sub.

Have you looked at the manual? There is no internal source that would produce 7.1 audio other than the test tones. Attach a multichannel source according to ITS manual.

LCD will display which speakers are active. And this depends on 2 things: the source signal and decoder mode.
If source signal is stereo, only front L+R speakers are used. For 5.1 signal (for example DVD over HDMI / optical/coax spdif) all speakers installed (which are not set to None) are used.
To listen to stereo input signal using all speakers, switch decoder to enhancer mode.

Restoring your T 747 to its factory defaults: At FM mode, press and hold front panel’s LISTENING MODE button until the VFD shows “Factory Reset”.

Cheers!

You will need to go to audio set up and make sure it is set up to play with a center chanel if you have one as well as the surrounds. You can also only have side a speakers selected when trying to use surround. If you have b selected it will play in stereo only

mine got fixed by replacing the front panel PCB with control processor. Only 350€...

try to calibrate the speakers from audessy rom menu,i did it and it lokes like it just needed to register all the channels,hope it helps.

To reset the the T743 hold down the video 6 and the source up buttons for 3 seconds. then power up from the back button

Hi Linda,

It is showing two because the source of the sound that you are listening is probably stereo only thus only two sound comes out. You could try to change the mode to 5 channel stereo or prologic or dts-6channel mode in the surround mode to hear your sound in all 5 speakers. best thing to do is watch a dvd which would use all 5.

Regarding a/b yes if your receiver supports it which i think it does there should be place for it in the back of the receiver.

good luck

smeags.

Press the "Listen Mode" button to put unit into the surround mode of choice. Pictogram will show which speakers are active.
