Morning all,
My son has just bought a new headphone amp and headphones for use with his pc.
The amp has arrived and is very good with his MacBook Pro:
MacBook (3.5mm jack) -> (RCA) Amp -> Headphones
There is no noise at all using this setup.
However, if used on his desktop PC you can hear ‘static’/interference (e.g. can hear when mouse is scrolled on screen, etc.), again using 3.5mm on PC to RCA on the back of the amp.
We’ve tried using separate wall plugs instead of both being plugged into the same power strip, but this didn’t work.
Our thoughts are that this points to static being picked up on the internals of the PC and fed through the jack and being amplified by the amp. Without the amp, there is no noise through the headphones. Could this be fixed by using an external DAC (would have to be USB), or is there something else at fault in the setup somewhere?
(By the way there’s no noise at all when used off an IPad too).
Very grateful for any help with this problem.
Thank you,
Phil.
