I have a Phonic 740 powered mixer with two Phonic S715 speakers and a Gemini GVX SUB15P powered subwoofer. I know this is a terrible combination of PA equipment but it'll have to do because I am on a strict budget. I connected the two S715 speakers into the mixer from the back main. Then ran a TS to XLR cord from the back of one of the S715 speakers into the subwoofer. This was working great for awhile then one day the subwoofer stopped working. I don't know what caused it as a lot of different people use this equipment. I know this setup worked with the 'tape in' input with the RCA to 3.5mm hookup.

But the prongs got stuck in the 'tape in' input so I have begun using the AUX in input. Could this be the issue? Please could someone tell me why the subwoofer has stopped working?

Is it the fact that I am using the AUX input? Any help would be appreciated. Basic drawing of setup: Mixer and speakers: Subwoofer: Subwoofer cord that was working: AUX input.

You seem to have been running a speaker signal into a line input. The sub is expecting a line signal and the signal coming of the back of the speaker is many times greater than a line signal. Therefore, I would guess the sub is now in a very bad mood. As mentioned above, the proper way to feed that sub in your situation is with an aux. Your mixer does not appear to have an aux, but if you don't use FX, you could use the EFX send for the sub.

If you are using the FX, then use the front panel main out. It's a line level signal and you can plug your TRS right in. OK, I deliberated a bit and realized something. You are running a signal into the aux in, correct? You first need to turn up the aux using the Aux In fader.

This will route the signal to the mains. Check that you can hear the signal in the main speakers. On the front of your mixer, you have a Main Out jack. This is a TS, unbalanced, mono signal. You can plug your TRS to XLR cable in here for your sub feed. Technically, you are sending a unbal signal to a balanced input, but the sub should be able to deal with it.

If that doesn't work, we may need more details. EDIT: I looked at the GVX SUB15P's specs, and its combo jacks do accept balanced OR unbalanced input. So with your current cable, you should be fine with a send from the Main Out. Spotlight on unix crack.
