ART ProChannel II Microphone Preamplifier and Compressor

Need one awesome ART preamp/DI? Get tons of clean gain, a powerful optical compressor, fully parametric equalizer, and both analog VU and LED metering.

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.

I have the rode k2 tube mic going into this bad boy. And for the price your crazy not to get it. I love it and I haven't even changed the Chinese tubes out but I got a couple jjs on stand by. I researched a lot before I got this and I'm happy with my decision. Just wish it was 2 channel.
