Pops from Layer D Only

[TD_IPFW]

I am getting severe [clipping] pops through my D layer on the SC48. I have a IO16 Digital card and FOH Card both feeding layer D.

I've seen similar posts regarding outputs, but not inputs. Whether something is plugged in or not, and muted or not, the PreAmps clip and pop, and pops do come out of the outputs on the IO16.

System is SC48 Remote, all 48 Analogs in the stage box, IO16 in the back of the desk along with AO16 analog output and FOH IO card.

At first I thought it was just the IO16 having a clock problem, but then the Talkback input started doing the same thing.

Thoughts or is this a Tech Support/Repair call?

Yep.
