Question about NAD T753 Receiver

Receiver surround not working - only downmix audio

Whenever I try to use a digital input with DD surround sound, I can only get Downmix stereo audio. Also, when listening to FM stereo, none of the simulated surround options are availlable (accessed through the surround button on the front). I would rather not bring in my unit to a repair shop as it will probably cost me more than what my T753 is worth. However, I would like to repair it and keep it myself. (I am an EE). Anyone have this problem before or have an idea of what to look at (Surround sound board), schematics, replacement boards? Thanks.

Why is there no sound when playing CD, but sound works when playing DVD?


Under settings in the DVD player go to the Audio.
Older CD's have formats that may not have the same digital format as newer DVD's. Set the audio output to PCM
Set the down mix mode if available:
To have the player downmix to normal stereo
Mark down the settings that you change. You may need to change them back for best DVD playback.

Loving the HD tv...have noticed a problem with my surround sound though. My kenwood amp auto sense's dolby digital 5.1 and some BD do work in DD 5.1 but most don't. It says DD5.1 on the package and the...


Your A/V Receiver must have the decoders for the source on the BD and for the newest audio surround sound you should be using a HDMI cable to the A/V receiver because the SPDIF optical or digital coaxial cannot handle the Dolby TrueHD and other newest codecs. Probably you are getting the down-converted audio because of this.

It sounds like the BDP unit is set to downmix PCM to the Optical Digital Audio output (the default). You need to change it to something like Dolby Digital. Crack the manual and look at all the digital audio settings you need to choose.

Got a Kenwood vr405 surround receiver, a Sanyo plasma TV, hd cable box and an insignia blu ray player. Both the cable box and the blu ray player are connected via hdmi to the TV and the TV is connected to...


If you would like to use high definition audio decoding, connect the HDMI from the blu ray player to the receiver. If that it not an option for you due to lack of equipment such as an additional HDMI cable to go from the receiver to the television for the video portion of the signal, then connect your optical cable again. After the optical cable is connected, make sure the Dolby Digital decoding is enabled on the receiver, and that the media you are playing also has a version of 5.1 surround sound. Then, enter the setup menu of the player (which I suspect this is actually where the problem might reside in your case) and make sure that Dolby Digital and DTS are not set to "downmix." Dolby Digital should be set to output Dolby Digital and so on and so forth...hope this helped.

Different Audio options from an older receiver


If your receiver has a multichannel input and the player has the multchannel output then that is the only way you can get surround sound from it with source inputs that it cannot decode, such as DTS. The player will then do it alone.
However, in the setup menu of the blu ray player you should be able to change the audio output to downmix to 2ch audio...at least you'll get to watch the movie.

Emerson dvd player - background sound lauder than dialogue


Greetings surfjax,

If you will allow me to make an assumption, you do not have a 5.1 surround system connected to your DVD player. This is a common experience with users of a standard TV or stereo receiver if a movie is being presented in 5.1.

In a surround sound system the center channel speaker provides almost all the vocal tracks while the side channels will provide music and some background noises. You'll still be able to hear the voices in your side speakers, but it will be muted and over powered by music or sound effects.

Some DVD players allow you to "Downmix" the surround signal to stereo. You might want to look around your sound setup on the DVD player or check your owners manual.

Hope this helps.
Jon

Dolby surround output


Make sure that you use digital inputs between source and your receiver and the input is seen as digital in selector. If you use analog connection, no DD signal could be transmitted.

Surround sound problems.


Dolby 5.1 is not supported via either of the Aux inputs. Be sure to check your main menu/audio setup screen to ensure that "stereo" is not selected. If it is, DVD's will not downmix, giving you only 2.1 stereo.
