The ART Pro Channel II Tube Channel Strip uses second-generation discrete Class-A microphone preamp to provide clean quiet gain while maintaining incredible transparency. The Pro Channel II is a powerful dynamics processor subtly controls transients and noise of the most demanding sources.
The ART Pro Channel II Tube Channel Strip‘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.

Full feature mic pre.
Oct 31st 2010This tube mic pre has most of the pro features of a mic pre. Though you have to be careful with how much level you send to the tubes. I try to keep the levels for the tube character to be within the "clean" indicators at ALL times coz I find the mic signal becomes kinda distorted at the "warm" range and above. The unit does what it advertises which adds warmth to your signal. Upon switching to different brands of the three tubes inside the box, I still was not able to get a very clean mic sound. But for its price, it's worth looking at if tube sound is what you're looking for.

ART Pro Channel
Apr 12th 2006This piece just begs you to experiment with it! My recording rack has 2 of these in it, and I'm using them to record bass and snare drum, vocals, and guitars. I find them to be very versatile, clean and toneful. They have tons of gain, and have 3 tubes in them for the mic pre, compressor, and EQ sections. I swapped these tubes out in mine with 12AT7's to make them sound a little cleaner and better to my ears, and this is an easy mod. I especially like the variable-mu compressor settings and find that they can be very transparent or aggresive-sounding, while still sounding very musical. It's nice that the Pro Channel has two types of compressor circuits to tweak. You can get the mic pre to be very clean or give a raspy distortion if that's what you're after, too. All in all, I'm glad that I have a pair of these ART Pro Channels and would recommend them to anyone to try out. Plus, they do work very well for recording bass guitar direct!
