    I recently got one of these, but it seems to have a noise issue. Every few seconds or so it booms loudly, like an extremely loud metronome. I have tried adjusting levels, changing cables, etc. but with no change in the behavior.

    Any suggestions or ideas would be greatly appreciated.

    If it is new, take it back and exchange it. If it's used take it to a tech and have the filter caps looked at.

    Thanks for your reply. It is used. Any idea how much the cost is to replace the caps? Thanks!

    I would suggest you contact Behringer support, even if it is used. If it's a common problem they might be able to tell you.

    Walking into a tech and saying you think it needs new caps, is bound to cost the cost of new caps. :bag:
