Peavey XR 684, adding subwoofer

Our Church currently has a Peavey XR684 Stereo Powered Mixer which is currently configured in monitor/main mode, the mains are 2 custom built 3-way speakers and there are 2 monitors also. The system has a great sound and has performed well for us.

Our question: Is it possible to add a subwoofer to this setup, and if so, what would be the proper proceedure. (Rewiring the speakers, crossovers, series/parallel wiring?)

Thank You for your input!

dware,
Welcome to the forums and hopefully, your interest in sound reinforcement will keep you here for awhile....there's plenty of material to soak up.....

I am not sure about the 684 model, but I would think that you have pretty much maxed out your system. You might be able to add a powered sub through an out of some sort. I do not know if the "outs" on the front ALSO disable the link to the internal power amps. If they do not, then you could hook up a powered sub with a low pass filter (like a PV-118D) to the Left or Right out.

Cheers,
Steve

Steve is on the right track.

You can use the MAIN out on the front of the XR684 to drive a powered sub or to drive another power amp to power a sub. The MAIN out is not balanced, so if you are locating the amplifier/sub more than 20 feet away you will want to use a direct box to convert the signal to low-z. A great thing on the XR684 is that the outputs are non-interuptive (they don't stop the signal from getting to the internal power amps).

The PV118D is a good sounding sub that powerwise, would be a good match for you system. If size and concealment is an issue, you could check out the SSE110 or SSE210. I've installed a few of these in churches and the SSE210 is particularly impressive for its size. Use the appropriate IPR or PV series amplifier and engage the sub crossover in these amps.
