Proudly own a QU16 for 2 weeks now. Soundquality great etc. but Last week during band rehearsal couple of times stereo channels went down, twice the drum machine and once a keyboard stereo channel. So faders down and also no sound. Clearly very noticeble … Setup very straightforwerd: QU16 with some mics, guitar (line6), bass, keyboard/synth, drum machine. With USB drive connected for direct recording (no computer connection)
Anybody same sort of experience, suggestion what goes wrong ?
