Overview
The ART Pro Channel II™ uses second-generation discrete Class-A microphone preamp to provide clean quiet gain while maintaining incredible transparency. A powerful dynamics processor subtly controls transients and noise of the most demanding sources.
The ART Pro Channel II™ ‘s semi-parametric EQ offers wide tune-ability and can be patched before OR after the dynamics processor. Separate rear-mounted insert points allow patching in external signal processing gear immediately after the Mic preamp and before the EQ and dynamics processor. Both analog and LED meters provide a detailed indication of audio levels.

UPDATE: Changed the Pro Channel II to a Furman AR regulator and the buzz is gone, noise floor is very low now, I was using a cheap-ish regulator to test it and the buzz was there but with the Furman it's working as it should at 120v, dunno if I should try snipping one...
