Processor Loop

A processor input on a lot of pre-amps just passes the signal directly from the input jacks to the pre-amp's outputs. ARC's in particular are wired that way. That arrangement is the very rational for the input! But Swampwalker is right---the inclusion of the word "loop" implies the input is NOT a straight pass-through one.

Thank you all very much!

If its a loop and not just a processor input then I THINK it will control volume.

Man...are we getting old, or what.

The processor input does not provide any gain, however, so your cassette deck will need enough output voltage to power your amp.

yes. In the old days before processors, they called it a tape loop.
