ProChannel II Class-A Tube Microphone PreAmp 2U"

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.
