Re: 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.

All 5 speakers work on test mode but on surround sound the left and right rear speakers are not working. How can this be?

Hello Ruby,

This is because your receiver is not in the correct surround sound mode for the number of channels being sent from the audio source, i.e. your TV or DVD player. It is likely your receiver is set for Dolby Digital (DD). You will need to switch your receiver to a Dolby Pro Logic (PL or PL II) setting to get audio from the rear speakers using your current audio source.

If you are unsure how to do this, please reply to me with the brand and model of the receiver. Some receivers have a "Surround Mode" button on the front of the unit or the remote. If you want to include further details of your setup, I can also give you some advice on attaining the best audio quality with the equipment you are using. You may be able to get Dolby Digital surround by changing some audio settings on the audio source or using a different connection.

Hope this helps. Please let me know if you need further assistance.

I am having trouble getting my surround sound to output my foxtel dvd using standard av cords is there anywhere i can get a diagram

Hi, I'm not too sure what you're asking - do you mean that sound is only coming out of 2 of the speakers? A lot of foxtel shows aren't meant for surround sound - usually only box office movies.

For best results, use a digital optical cable (not the one with a round end, one that's fibre optic, say that to a store and they will give you the right one) - connect to the optical/toslink input of your surround sound system.

You may have to turn on "dolby pro logic 2" to get all speakers working on some shows. Or you can try just plugging in the 2 red/white stereo cables into the amp, and using pro logic that way. Pro logic creates surround sound, even when your show is only stereo.

I guess that will do it .

Have a nice day.

My receiver switched from dolby digital to pro logic, but I cannot seem to get it to switch back. It is connected through optical audio to a motorola qip7100 hd receiver. i know that the channels are...

Check the settings in the Motorola to make sure it's outputting Dolby Digital instead of PCM stereo.

Indicators on the receiver can tell you if you're receiving mutlichannel audio or not.

Kenwood 107VR rec and No vol from Sub Output w/ menu Opt On

In the setup menu are the speakers set to large or small? On some receivers if you have it set to large all the bass is directed to the right-left fronts.
On my pioneer receiver if the speakers are set to large the sub-pre-out only works if the receiver is in a surround mode, if its in stereo mode and the speakers are set to large the sub-pre-out is dead. If the speakers are set to small the sub-pre-out works all the time.
Also, some receivers won't send a signal to the sub-pre-out if there is no LFE discreet signal info from the dolby digital or dts bitstreem.
For example I have several older dvd's that light up the L C R SL SR icons on my receiver, but don't light up the LFE icon. I have other older dvd's that just light up the L and R icons meaning they are only recorded in stereo like a vhs tape recorded in dolby surround.
In my basement I also have a kenwood dolby digital receiver.
I've noticed that when a dvd only lights up the left and right icons the pioneer will automatically switch to dolby pro logic surround. The kenwood will only send the signal to the left and right fronts (stereo). If I manually switch it (kenwood) to dolby pro logic I'll get sound from all the speakers just like the pioneer, but it does'nt do it by itself.
Most receivers that have a tape monitor won't work in surround mode with the tape monitor on. The pioneer will let me use the tape monitor with dolby pro-logic but won't pass through a dolby digital signal with the monitor on.
Hope this helps.

Can i plug in my i-pod and listen to it?

All you need is either a dock, which will keep the I-Pod powered up, or a 3.5mm plug to two RCA phono leads, which will also be needed for the dock, this plugs into your headphone socket of your I-Pod and the two RCA's into an aux socket on the JVC. You can then listen to it in Dolby Pro-Logic. You won't be able to listen in Dolby Digital, unless the I-Pod has Dolby Digital output, which will require a different lead.
Of course the sound source (music) would have to be recorded with Dolby Surround, to get the full benefit, but many are, they just don't say in the imformation given.

No dolby digical in DVD mode.

PCM mode will not output dobly digital, use the digital cable connection, not RCA cables, set DVD audio output menu to Dolby digital or DTS. On DVD software menu setup select audio then Dolby Digital 5.1 or Dolby Surround.

Does not decode Dolby Digital 5.1 from my cable box

If you have an HDMI cable plugged into the cable box it may only output 2.0 on the digital audio output. Set the HDMI audio to off or 2.0 and then set the cable digital out to Dolby.
