Description

The JDK Audio MP R-20 is a dual channel, high quality microphone preamp, designed from the ground up by API's design team to offer a versatile high quality input for Mmicrophones as well as instruments.

Each channel features both a mic and an instrument input, with switched phantom power, phase and pad.  Metering is traditional analog VU.

Features:

  • Dual mic preamplifiers with 54 dB of gain
  • 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
  • Switchable 48v phantom power
  • Low distortion, low noise circuitry
  • Fully balanced output, both 1/4" and XLR

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.
