A really useful bit of kit------for miking up quiet sources.

22.01.2016
OK not often used in Rock & Roll... But for difficult mic jobs, people who whisper to a microphone- or people stay too far away or the mic is too near the speaker-.-.-.- and feedback is inevitable if you try to turn up to a good level.----- Then having this in the signal path can get you some more Dbs. The benefit varies with the different setup of each venue. Maybe about 6 Db more gain before feedback. And best of all the tendency to jump into sustained howling is reduced. You get warning colouration before full on howling while working at a louder level than otherwise possible. Also has an excellent auto mixer, really a switch between two mic inputs silently switching to the loudest. So fabulous for two mics on a lecturn without phasing but still the freedom to wave the head about. BUT if you have time do ring out the worst frequencies with a 31 band first for best possible Gain Before Feedback

Do what he is supposed to do

ZJCMB, 30.05.2015
We had constant feedback, as the ceiling speakers (unfavorable) were installed near the stage. So we installed behind the mixer (and before the amplifier) ??the feedback suppressor. A few settings at the rear, and everything works ABSOLUTELESS feedback-free, even if one would have it really loud. The language reproduction is great, with music does not sound nice any more, then one should do without it - a pushbutton on the front side, and already everything 1: 1 will give back.
