Hi Everyone – completely new to forums so please excuse if I don’t follow protocols properly. I have used mixers for many years although my main involvement with sound has been the design and installation of systems. Have just bought a QU16 and feel that the inclusion of some form of automatic feedback suppression would be a definite advantage. While system knowledge and proper training goes a long way towards eliminating most problems, we must remember that in the real world, room acoustics, budget constraints, operator experience, and the time and position constraints involved when using portable systems can all play an overriding part in the end result. Although the QU16 does have variable Q parametrics which are great for notching out the one or two dominant feedback frequencies which sometimes occur, most users of a QU16 size mixer aren’t trained to the degree that they can immediately recognise what those frequencies are. The RTA puts you in the right area but how much easier if the desk just did it for you – or at the very least, gave a readout of what the loudest frequency was. The last three mixers I have installed have been QSC touch-mix’s. While automatic feedback removal was not a primary consideration in their selection, given the skill level of the users, it was a factor.
