    Great video evidence!

    The only suggestion I can offer is to thoroughly clean the 1/4″ 2Trk output jacks with something like DeOxit on a nylon brush. I use baby bottle nipple brushes from the drugstore..

    If a cleaning doesn’t fix it, it’s time to file a support ticket and procede from there.

    You’re right and your proposal is OK. But if you need to clean exit. Mixer was purchased on 01 February. Now the dealer tells me that you need to send an authorized service. I do not understand a new mixer expensive 15 days old and already in service

    These things happen. It could be as simple as a poor solder connection to that jack or possibly something coming unseated during shipping. These things travel thousands of miles via multiple carriers.

    I think you’re lucky to have found the problem early, actually. I’m sure it will be a warranty claim. And the video is good enough for any A&H personnel to get right to work on it.

    Best of luck.

    This is the response from the service. The reason was that the mixer and amplifier were switched to a different stage and I’ve gotten feedback current through cable carrying audio. Will I protect mixer if using Palmer Line Isolators. greeting

    So was there an electrical current applied to the mixer via the 2-track connection?

    If you are interfacing the Qu mixer to another or other systems, then yes, I would place isolation transformers in between. For me that is Standard Operating Procedure…SOP.
