Hi all, I posted a little while ago about an issue with a Topping A90 and received a lot of very helpful tips and info. I’m hoping to get some assistance with a new issue.
After doing some research, I recently picked up a Motu M4 to use as a DAC for some headphone amps, as well as for ADC. However, I’m having some confusing buzzing issues which I can’t really understand.
For extra context, the setup I'm trying to use involves running the MOTU into my THX 887 via RCA so that I can connect another SE amp into the SE passthrough on the 887. I’m using RCA outputs 3+4 since they run at line level.
The interface seems to have a buzz at higher gain levels when connected to my amps solely via RCA. However, I can get rid of this noise in the RCA outputs completely by adding a single TRS-XLR cable between the M4 and the 887. HOWEVER, I have to plug this cable into either output 1 or 2 on the MOTU, otherwise I can hear bad distortion in the signal coming out of RCAs 3+4.
So… what is going on here? Does this sound normal, or is there something wrong with my interface / amp?
Really appreciate any insight I can get on this. Thank you in advance.
