Just a positive feedback with the CQ12T who ran again during 4 days of show with absolutely no issue.
Setup was simple, just a stereo music track, a HF mic and monitor (dance show).
We ran 4 lines with a 50 meters RJ45 cable with splitter from sound management desk to stage, 2 lines for L/R FOH, 1 line for HF mic and the last line for stage monitor.
Hot and dusty conditions but all went very well.
Easy inside cleaning of the CQ after the show, just a few screw to remove to access the board and genteelly clean all dust with air and light brush.
