(Attn: @electricmotion)
Whelp to update this I put a noise filtering splitter into the mix but could still hear PC noise. Went on a frantic, sweaty hunt for the culprit and nothing made any bit of sense. So I said fuck it, put a DI Box (ART RDB) on the outs of the RNC and
Gone. All the noise problems (hum, pc mouse etc) I’ve been plagued with for so long just disappeared. I’ve never heard my system so quiet.
Maybe it works without a DI for some people but it sure as shit wasn’t working in my system.
