The Tube MP/C (PreAmplifier/Compressor) from ART 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.

The preamplifier’s active balanced solid-state input provides extremely low noise and excellent common mode rejection. The ¼-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.
