The Tube MP / C (PreAmplifier / Compressor) is a multi-purpose tool for audio engineering and recording. 2 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. ART's Tube MP / C circuitry is a hybrid design utilizing the latest, most advanced, solid-state and tube technology.

The preamplifier's active balanced solid-state input provides extremely low noise and excellent common mode rejection. The 14" 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 20 dB of gain.

The compression circuit features a VCA-less design and utilises optical electronics (Vactrol) coupled with a 12AX7a vacuum tube gain stage for superior musical performance
