: Do i need to use TRS cables or can I use TS cables?
TS should be fine.
Routing: I am leaving it on Insert as I am not (yet) doing a stereo send/return to my QC (which would require cables be run to/from those I/O’s)
Insert should be fine.
Should I see signal activity on the Input Level Indicator?
With a signal in input jack 1, you should see activity on the channel 1 meter above the display, yes.
Is it ok to keep it set to Instrument vs. Line for the Input?
This depends on how the QC is configured, but for the moment Instrument level should be OK.
There are some further things you can do to troubleshoot your design:
– Does your H90 work correctly when set up stand-alone (i.e. without the QC involved)?
– Does the QC return channel get audio when the H90 is relay bypassed?
