- Custom analog VU meters for monitoring output level
- Front panel, high-impedance instrument input with 45 dB of gain
- Peak indicator
- Pad switch attenuates the microphone signal by 20 dB, or the instrument signal by 10 dB

The MP-R20 provides two channels of premium analog microphone pre-amplification designed to provide a low noise, solid front end for all audio applications. Meticulously detailed and solidly constructed, the R20 features custom analog VU meters and hands-on analog control of the gain level. Individual toggle switches control the selection of 48v, polarity, pad and a mic/instrument switch.
