Question

Recently my AR8 mixer has started giving off a high frequency whine, which I assume is a coil whine, sometimes it can be really loud or be soft enough to be drowned out by everything else. Mixer still works perfectly fine otherwise; it's just really annoying. Have tried putting the mixer on a different circuit to see if that would eliminate the problem but nada. Is this something I, with no knowledge of electronics, can fix or send it off.

Another follow up - I'm having the same issue.

Answer 3

contacted my local PreSonus distributer and organised  to ship it to them for repairs. Unfortunately the postal service lost the package; compensated for the unit. Sorry guys, won't get an answer from me.
