NO SOUND FROM MY SPEAKER SYSTEM. EVRYTHING ON THE RECEIVER SEEMS NORMAL. SUB WOOFER INDICATES IN A STANDBY MODE WITH NO DIGITIAL INPUT FROM MY RECEIVER. MY DOG CHEWED THE SUBWOOFER CABLE INTO. REPLACED THE CABLE AND THE FUSE IN THE SUBWOOFER. STILL NO SOUND. ANY IDEAS?

It sounds like you overloaded the Denon avr with too much resistence from the speakers. Please check the total resistence of the speakers before you connect them all. Also check that the speakers or their wires are not shorted!
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 DenonAVR-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
I have a very similar problem with the same exact Panasonic sub. I went to Best Buy and Radio Shack looking for an adapter, and they basically told me that one does not exisit. Apparently, Panasonic designed the home theater system specifcally so that it could not work if any part of the entire system was ever seperated.
If your tv is putting out mono you will only get the center and sub speakers. This can be because the tv is only mono, or the output is set to mono in a menu of the tv. If you have cable or sat run the digital audio out to you receiver; it usually sound better that way anyhow. Set your receiver to Dolby mode for best sound.
