ART Project Series: Tube MP/C - Tube Preamp with Compression

This killer preamp is perfect for adding a high quality preamp to your existing recording or live sound rig, the compression features on this model are the most extensive for any compressor in the 'Project Series' so if your looking for compression and the warmth of a tube in a preamp then this is your pre!

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. 

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.


  • Tube-based mic/line preamplifier with up to 80 dB of gain
  • Hand-selected 12AX7a tube
  • Optical (VCA-less) compressor circuitry = transparent dynamics control

    so good I bought a second one

    very good value, great home studio D/I, Preamp, Compressor. Sounds much better than it should at this price. great with my tube mic, amazing "black-face" clean guitar, great vintage bass tone, ran my roland drums through it as an experiment[wow] and had to get a second unit so I could use the stereo output from the drums. Compressor is subtle and user friendly.
