The Kopul BOOST-MATE-20 is a compact inline microphone preamp and signal booster made for low-output dynamic and ribbon microphones. It adds continuously variable gain from 0 to +25 dB, strengthening the microphone signal before it reaches an audio interface, mixing board, or microphone preamp.

A stepless output-level knob provides precise control over the amount of boost, making the unit suitable for vocals, podcasting, streaming, interviews, broadcasting, studio recording, mobile production, and live performances.
