I have done some pretty detailed trouble shooting on this and just want to know what additional equipment or things to try to eliminate the electronic buzzing noise I get.
- PC Line In Jack
- Behringer Xenyx802 8 channel Mixer
- Behringer MDX4600 Audio Compressor/Limiter
If I connect ONLY the mixer to line in jack no interference is heard and recording audio sounds just fine.
Connecting ONLY the compressor to the line in jack with the POWER OFF and the power plug connected in any socket or surge protector... the buzzing/chirping noise is heard when 'listening' to line in input on my USB headphones.
If I connect the same compressor and/or mixer with the power ON or OFF, but to a DIFFERENT computer... there is no problems and recording audio sounds just fine with the compressor doing it's thing.
So I am left with feeling it is something unique to the computer I want to connect to, which has nothing out of the ordinary and is a brand new PC. It uses the onboard motherboard audio jack with the same audio driver as the other PC.
Any ideas? I am not sure if since it is obviously something to do with the power or grounding connection, if a line power filter or something would help.
