    Hey everyone.

    I have a Yamaha Subwoofer at the moment. I am going to be buying a new Receiver for my setup.

    On my subwoofer, the way it connects to my current receiver: which is a DVD/Receiver all in one, It connects using a subwoofer cable, and another cable: A 3.5mm headphone type of cable from the sub to the receiver.

    Now, I have seen the back side of the receiver I am going to be getting. It has 2 subwoofer connections. One called "Subwoofer Output" and another with other connections called "Multi Channel Input" . Those connections do not look like you can plug the 3.5mm cable into them, Only the standard subwoofer cable.

    I'm saying this because when I unplug the the 3.5mm headphone looking cable from the subwoofer, the receiver shuts off, or no sound goes to the subwoofer. But once I plug the cable back in, sound goes to the sub. I'm afraid that my subwoofer will not work with the new receiver.

    That may/may not sound confusing, but I worded it the best I could!

    Any help is greatly appreciated!!

    sounds like it pulls power from your current receiver, is that correct?

    In which case if the sub does not have it's own power it will rely on the receiver for power, if the new receiver does not have that power, it will not function. Another thing is they way you say unplugging the sub shuts off the receiver, you might have a sub that has a built in cross over. Does the sub have the speaker outs on it?

    My subwoofer does have its own power supply. The way it connects to the receiver is with 2 cables. A standard subwoofer cable, and also that 3.5mm headphone type cable. The receiver shuts off when I unplug the 3.5mm cable. Not the Subwoofer cable.

    So yes it does have its own power supply.

    The connections on the sub are in a little white outlined box with the following 2 connections saying:

    System Connector <-- This is the cable that shuts off the receiver when its unplugged.

    So I'm not sure if it will work with the new receiver.
