existing equipment is PEAVEY XR 800F 9channel console which currently connects to cassette recorder via 2 white line ins and 2 red line outs
Gotcha. So it looks like that mixer has a "Tape Out" that you're probably running into your cassette recorder. I don't know what your price range is, but what you're going want is something like this: (http
