Behringer Xenyx 1204USB

Developed intermittent connections in the first stereo channel, that disappears when a sufficient high voltage is present. Usage has been five events per year, mounted permanently in a 19" rack in a flight case.

Features I miss the most is a peak level meter to monitor the level at the channel inputs. When the only indicator is the red "Clip" LED, it gets harder to optimise the gain setting, i.e. setting gain under a rehearsal/sound check and taking into account that musicians inadvertently play louder during a concert.

The extra hiss produced when turning faders up over 0 dB, makes the usable fader travel smaller. It also makes it more difficult to set a 'gain structure' that gives a good SNR and some headroom before clipping.

Great for training people in getting the best out of analogue mixers.

USB audio interface works fine with Linux, Windows 10/7 and probably OSX (playback was tested).

The mixer worked as expected, primarily for spoken vocals and music playback (in a pinch for a live band), except for the channel that became defective.
