Question about Sony STR-DE897 Receiver

1 Answer

My dad has a 7.1 home theater speaker system, and I've toyed with the STR-DE897 receiver to get all of the channels to work, but I can only get the 5.1 to work, any idea how to get the 7.1 to work?

It needs to be encoded on the media such as a DVD movie or CD - it should say 7.1 surround recorded. I'm assuming you have all seven speakers and sub-woofer hooked up, too?

I have a sony STR-DE897 and my rear speakers dont get sound when plugged into the surround back ports..Is there a certain setting in order for the rear surround spreakers to work? or does that mean the...

There are a few things required for the rear surround channels to operate;

1. The surround back channels must be enabled in the surround setup menu.

2. The media being played through the receiver must have audio encoded for the rear surround
channels. There are only a few exceptions to this but I'll exclude the explanation for simplicity.

3. The audio level of the speaker channels must be set high enough to be audible.

Enter the surround setup menu with your remote. Use the center button on the remote to toggle through the selections, press down on it to enter the selection.
You will navigate to a selection in the surround setup menu that says "surround back" or S/B with a selectable yes or no indication. Press on the center button to enable them.

Media like DVD or Blu-ray that has 6.1 or 7.1 channel audio has separate, or often referred to as "discrete" or "matrixed" audio intended for playback through surround rear speakers, depending on the music or movie. If your media is encoded for 5.1, then there will be no audio sent to these speakers. However, with the different modes of on-board digital processing of this receiver you can still have audio through these speakers.

Last but not least is the actual playing level of these rear surround channels. They may simply be adjusted to quietly. Enter the setup menu with remote, choose "level" and navigate to the rear surround channels. You can adjust the level up or down in 1/2 dB level increments by toggling left or right with the center button. Each surround channel can and should be adjusted independently and equally.

Rear speakers L and R not working

if its a 5.1 channel home theater,it means you have to hook up the subwoofer or maybe a center speaker to its terminal to have them all working. 2 front speaker,2 rear speaker and 1 center speaker or subwoofer =5 and amplifier is 1 so it is a 5.1 channel.hope this help..

No sound

It looks from the picture that this thing has a built in tuner. Try that first. If you are not getting sound from the tuner then inspect your speaker connections. Does this receiver have A/B channels for different speakers or different modes for surround sound? Did you try adjusting those? It is highly unlikely that it is broken, good luck!
