Unable to get my sub to work with my Denon AVR 1506 Receiver

Does the receiver, Have a (RCA) Jack on the back of the unit ,Where it is written sub out,If it does, You need what is called a sub conecter patch cord to hook up the sub.If it is a powered sub, If the receiver does not have a sub jack you can not hook up a sub to it.

Look for TONE CONTROL

Sure, just get an RCA splitter and share the Sub Pre-Out with the two self-powered subs or one amp powering two of them.

You have to let the Denon know it has a sub or it won't send anything to it.

I can't find the manual but I'm sure you could dig through yours and find the area concerning speaker set up.

In the setup menu on your denon receiver make sure the subwoofer setting is set to ON or YES.

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.

Most receivers only handle one sub at a time. If you are deadset on connecting two, you might want to consider how much power your receiver will give to each if you split the signal then determine the power of each sub. If the subs aren't the same you can be sure they will sound strange.

If they are identical and your receiver has enough power to handle them both, examine the connection the subs use to connect to the receiver and split the connection by buying a splitter at a local radioshack.

You will probably be better off using the better of the two subs instead of having both connected. Your sound quality will be more balanced and clear when it comes to bass.

why don't you both return these units and call Denon for replacements without these problems?  Sqeaky hinges get the oil.

There is a setting under your speaker setup to turn the subwoofer on. If speakers are set to small it auto matically sets the subwoofer to ON. If the speakers are set to large it turns the subwoofer off but you can manually adjust.

Yes on B Connect Left+ Right+ Equals Mono And Turn on B Side with A
