Ok so while Im not a total newb I am by no means an expert. Im having an issue with a Behringer FBQ6200 that Im hoping someone here can help with. Said issue is that Im only getting one of the channels to output equalized sound. Ive swapped output connections, and Ive swapped input connections and the same eq channel has no equalized output which is leading me to believe that there is a problem with the eq internals, but there are a handful of switches and buttons that i may not have the right ones pressed or not pressed, except I put them to match the channel that provides equalized output but still nothing not to mention that the same wires input and output work on a different eq.....Thanks in advance for any and all input......And yes the attached pic is what the eq is used on......and yes they all play at once in my living room, but theres more not pictured........
