Subwoofer is not playing


It is hard to say. The sub-woofer has its own amplifier, although it is supplied the sound data from the main amplifier. It could have a problem with the battery power circuit (Sub-Woofer Amplifier Connector Pin 6, LIGHT GREEN/VIOLET) or it could have a problem with the GROUND circuit (Pin 2, BLACK/LIGHT GREEN) Or it could possibly not be receiving the signal from the main amplifier (Pin 7, BROWN/ORANGE "+"), (Pin 8, RED/BLACK "-"). Or it could be that either the sub-woofer speaker is blown, or the sub-woofer amplifier is defective.
There is also a "High Audio Mute" circuit that connects between the main amplifier and the sub-woofer amplifier.

I recently purchased a new Denon AVR-391 receiver and am having a problem hooking up my subwoofer. It seems that the Denon has a pre-out RCA looking output and my subwoofer uses conventional speaker wire. ...


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

How to hookup


hi,
if u want to hook up the sub with ur av receiver the connect the sub woofer output of ur AVR to any one (left or right) input of ur sub woofer. then connect its power . set the frequency range between 90 and 120Hz. set the volume of sub woofer to 40% of its total. also check the av receives speaker setting. goto speaker setup and make ON the sub woofer out.

if want to connect the sub to a stereo amp without sub out. then connect the amps speaker line to the speaker input of sub woofer and connect the speaker out of sub to left and right speaker ( make sure to connect the red to red and black to black). set the volume and frequency as above
ok
