The JDK Audio R20 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 microphones 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.
The MP-R20 provides 2 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.
