I have a QU16, im upgrade the firmware to version 1.6 without problems.
During a live show, when the console just passed 0db on the Master, the sound goes inward like as if limiting itself. or as if he had a lit limiter.
after doing tests before the show, im downgrade the firmware to version 1.5 and the problem did not exist more, I had no problem with sound,
The point is that, with version 1.5 can not use my ipad app.
I will try filming a video showing them promptly detail to which I refer.
Any of you has the same problem?
