Sorround Back Speakers not giving proper output

Well isn't this just a find how do you do!!
It appears that on this set there is no headset or other audio connection other then the optical?

It appears the only way to a traditional RCA audio jack is via a special adapter. See image. Inexpensive not sure of the quality of audio.

The best way would be to purchase a sourround sound speaker amp system with 5 speakers plus base woofer. These surround sound systems are usually have optical connected and for best results this would be my first choice.

Some have wireless back speakers to allow for easier installation.

RCA RT2781BE 1000W Home Theater System with Bluetooth This unit has two optical inputs and one digital input.

This is an inexpensive surround sound speaker system that should connect to your Panasonic TV optical output. Very available and I wanted to give you at least one option. Wires etc are a mess but the surround sound can be amazing. I would check all the reviews if you decide to go with this type of audio system. They can be confusing and in your case you need to have input control of volume with optical.

The following link is the manual for this particular Home theater System.

These audio systems can be very expensive. Less expenesive sorround can still provide great listening results.

Hope this helps?

dude
the logitech sound system only can work on better sound cards
u can purchase creative sound card or logitech sound card
than install the sound card on ur com
and u can listen ur all speaker

Hi,
Your sub-woofer apparently does not have an amplifier built into it. This type requires you to use your front left and front right speaker output to got through it to your regular speakers. It is called a passive sub-woofer for that reason.
To set it up, Connect your front speakers to the "output" of the sub. It should say "to speakers" on it.
Then connect the Speaker Outputs for the left front and right front on your Denon AVR-391 directly to the Sub. It should say on the back of the Sub "to amplifier".
Here is some theory you should know, if you don't already know it, that will help you get a satisfactory result in setting up this system.
There is a condition on setting up all speakers and subs that not everyone know. It's call "phase alignment". Phase alignment (A Good Thing) refers to all of the speakers in a system moving in the same direction (in and out) at the same instant in time. This gives you much clearer sound and better response from your sub-woofer.
Phase Cancellation (a bad thing) is when some of the speakers are moving out and other moving in during the very same instant in time. It causes problems in sound.
IN A SUB-WOOFER, IT CAN CANCEL OUT THE LOW NOTES.
Here is how to handle it:
On the back of the receiver the speaker terminal outputs are colored Red and Black. Black is considered negative and Red is considered positive. On the back of the Sub woofer and on the speakers the same colors apply. MAKE SURE THAT ALL OF THE CONNECTIONS GO BLACK TO BLACK AND RED TO RED WHEN CONNECTING UP THE SPEAKER WIRES.
The system will work either way. But you will have severe bass loss if the woofer wiring is out of phase because of phase cancellation.
Hope this helps,
Best Regards,
Mark


"Phase Cancellation"

hi,
select tv input on ur theater system. u can hear audio fro the frond left and right speakers. if u want to hear the audio from the surround speakers, then press the A-MODE button on ur remote to select different type of sound modes. press again and again to select different sound field. select one which suits u.
ok

Check speaker wireing make sure all positive and negative connections are correct. What cable are you running from tv or DVD player.check to see that wireing is correct on receiver for sorround speakers. Run audysee sound calibrator set up. Make sure correct settings for sorround sound in bluray player/DVD player

There is nothing wrong with it, it is set to only play in the region it was purchased from. That is how all DVD players are made, with regional settings. No repair is going to help, you just need a DVD player from the proper region to play those disc's.

this is something a tech expert on electronics can handle. even replacing parts has to be attended by a pro-technician. something is wrong with your DSP processor or system components. it could be the switch only or it could be the processor.

Try installing an old creative driver for digital audio but use system restore to take a backup of your settings first. Also, you may have to update the bios and unselect the AUTO mode for sound.

I would bypass the speakers from the projector and connect the audio output from the DVD to a sorround sound system or to computer speakers.

surround speakers will only function when the video that is being played is encoded with surround sound. like 5.1. otherwise it will only play in regular stereo mode.
