Question

Using my RML 32ai mixer in my Homestudio.

I have Hardwaresynthesizers connected. I've noticed unacceptable noise. I can deal with white noise-ish type of interferences but theres also a quite loud humming.

I plugged the mixer in another powersource (different phase). Didnt help.

I disconnected all inputs. Didnt help. I even still was able to see the meters of the Main-OUTs showing me "the" noise.

Whats that? Help

Load scene #1 (factory settings) and check, if the problem is still there. Use a microphone first, then check a line signal. If there is no change, call your dealer, if the RML is brand new, or open a support ticket in your PreSonus account.
