I have a Zapco PEQ along with a Zapco Reference 150 along with some other stuff. Anyways, the Zapco amp has balanced inputs and I dont really understand.
You need the symbilink cable to use the balanced inputs. But does this require a special HU to take advantage of these? Amd what is the real benefit to balanced inputs?
I see a Symbilink cable on ebay, but it has RCAs on one end, so what is the point?
The only point to running balanced is the possibility of reduction of induced noise. The balanced signal will eliminate any noise picked up throughout it's run. So the short story is that if you have no audible noise now, you won't hear a difference between balanced and unbalanced.
To actually utilize the balanced signal transmission, you would need a device capable of accepting unbalanced inputs and outputting a balanced signal (unless your headunit has balanced outputs, which not many do). Zapco ofcourse makes a unit that can do this (I don't know the model # off hand), and I'm not sure whether or not your PEQ already has this capability.
