Got another one for you . . .

On my last normalled patch bay config, I had my compressors set up with the outputs directly over the inputs. I don’t remember there ever being a feedback problem . . . but how would I know? When I plugged a cable in so I could have actually heard something, I would have broken the loop. I was about to do the same thing with a Korg Kaoss Pad processor in my new config, and realized that might be a dumb way to do it with the feedback loop risk.

So . . . in a normalled configuration, is it unwise to go top to bottom with processing gear? Does feedback happen without signal present? I would think even cycle hum in the system would eventually cause it to feedback even if I couldn’t hear it as it was happening . . . yet I never observed that happening in my rig.

Please let me know. THANKS!

Hey Chris,

The rule for outboard gear and effects is never use normals because the output is returning to the input and will, in fact, cause a feedback loop. So just de-normal the top-row from the bottom-row and you will be fine. No advantage for normals on your effects anyway.
