Product Description

The ART Tube MP/C Microphone Preamp / 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 microphone/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.

ART Tube MP/C Microphone Preamp / Compressor Features:

  • Tube-based mic/line preamplifier with up to 80 dB of gain
  • Hand-selected 12AX7a tube
  • Optical (VCA-less) compressor circuitry = transparent dynamics control
  • 1/4 inch unbalanced inputs and outputs
  • XLR balanced inputs and outputs
  • Transformer isolated XLR output
  • Selectable output range for Line/Instrument interface levels
  • LED meters for Tube Warmth, Gain Reduction and Output level
  • +48V phantom power
  • Phase reversal switch
  • Selectable release time settings
  • > 90dB dynamic range
  • Custom extruded aluminum chassis

The ART Tube MP/C 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 ART 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.
