404 buz problem

[shakey_hands]

hi

buzzing sound lasts for about 2secs (ive attached sound sample). this loops every 4 secs. it comes from every output. happens regardless of any volume knob setting. does not increase with increase in volume knob. the buzz happens through sample play back, its looping rhythm unaffected. samples distort during the buzz.

i havnt had the 404 long. it just started happening tonight when i turned it on


thanks
shakey

weird.. sounds like a synthesiser

Are u certain its not like an accidental looping sample that keeps playing over n over on a bank you didnt check? (or a pattern) I know it sounds stupid but double check..

Do you have the microphone or aux input on and are playing a synth ? (again.. sorry its stupid i know )

Do you have any effects turned on?

If its none of those stupid things then take it back.
