ART Pro Channel II - Professional Tube Microphone Pre-Amplifier / Compressor / EQ

Manufacturer ART Applied Research and Technology

Buy this from the A.C. Audio Online Store. Request more information or contact us now for purchasing information.


The ART Pro Channel IITM 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 IITM '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.
