ART Tube MP/C - Preamp / Compressor Direct Box
Superb Tube Sound
The Tube MP/C (PreAmplifier/Compressor) is a multi-purpose tool for audio engineering and recording. Two independent circuits featuring a tube-based analog preamplifier and a VCA-less compressor with optical gain reduction control are housed in one, convenient desk-top chassis. Used as a mic/line preamp or as a DI (direct) box, the Tube MP/C is designed to work seamlessly with any recording, sound-reinforcement, or electronic instrument setup. A R T's Tube MP/C circuitry is a hybrid design utilizing the latest, most advanced, solid-state and tube technology.
Fully Featured Input Strip
The preamplifier's active balanced solid-state input provides extremely low noise and excellent common mode rejection. The 1/4-inch high impedance input prevents loading of any connected device making the Tube MP/C perfect for DI or line level applications. The preamplifier's second stage 12AX7a tube runs on a regulated DC voltage providing an additional 20dB of gain.
The compression circuit features a VCA-less design and utilizes optical electronics (Vactrol) coupled with a 12AX7a vacuum tube gain stage for superior musical performance.

By: Patrick on 20 July 2014Best price around for this item. I'm using it as a bass guitar pre, feeding into the mixer and PA at band practice, which saves lugging a bunch of heavy gear around. Result is *far* better than the unprocessed bass. The tube gain stage does a nice job of warming up the sound, enhancing the lows and low-mids. The compressor is reasonably versatile despite the few controls, and can be very light and transparent or aggressive if that is desired. There are no equalisation controls though, but assuming the mixing desk has decent EQ then this is not a problem. Haven't tried it on acoustic guitar yet, but I can imagine it would be a great DI box substitute. Haven't tried using it as a microphone pre either so can't comment.
