JP,

You will need to systematically go through your setup to determine where the noise is getting into the system.

Is the noise there if you use different (hopefully known good) mic cables into the TRP? if yes then:

Is the noise there if you use different mics into the TRP? If yes then:

Is the noise there if you use different cables between TRP and ULN8? If yes then:

Is the noise there if you connect mics directly to ULN8? If yes then:

Is the noise there with nothing connected to the ULN8?

Answering these questions will get you along the way to identifying the source of your problem.

Regards,
