Analog Preamp, everything has been said before, compressor, feedback suppression.

Config general condition of having a simple notions of cuts. Anti feedback filters of 12 frequencies a bit too much for my taste.

Compression is natural but rather the anti feedback tends to sound too crushed or rather eat one of the sound spectrum. against by the preamp is very good (surprisingly better than the new consoles behringer).

For six months, but with the experience I would choose a rather good anti-feedback and a compressor, and preamps separate and much better quality for only 20 X more. C ca the great strength of behringer.

produced generally good for those who have no means great sound engineers ...
