PreSonus MP20 2-Channel Mic Preamp

Condition: Very Good

The PreSonus MP20 is a professional-grade two-channel microphone preamplifier that combines Class-A discrete circuitry with Twin Servo technology for clean, transparent signal amplification. Built with Jensen Transformers—widely recognized as the industry standard—this unit delivers the sonic clarity and low noise floor expected in high-end studio applications.

The MP20 features a fully equipped rear panel with XLR balanced input/output connectors, TRS line inputs via Neutrik combo connectors, and dedicated send/return jacks for integrating dynamics processors. The low-impedance stereo mix bus provides precise control over stereo imaging, while separate XLR and TRS mix outputs accommodate both balanced and line-level connections to audio interfaces and mixing consoles.

Housed in a single-rackspace steel chassis with a professional blue anodized front panel, the MP20 shares the same technical specifications as PreSonus's renowned M80 preamp. This is solid engineering at an accessible price point—built by a team with over 60 years of combined studio and live sound experience. There are some light scratches on the bottom but overall it is in very good shape.
