ARSENAL AUDIO R20 2 CHANNEL MICROPHONE PREAMP The Arsenal R20 is a meticulously detailed and solidly constructed dual-channel microphone preamplifier. Designed from the ground up by API's design team, the R20 features low-noise, high-quality inputs for both mic and instrument in a rack-mount chassis with internal power supply. Each channel includes rotary gain control plus individual toggle switches for phantom power, phase, pad and mic/instrument input selection. The dual mic preamps each offer up to 55dB of gain, while each front panel, high-impedance instrument input provides a maximum of 31dB of gain. Each channel's pad switch attenuates the mic input by -20dB, or the instrument input by -10dB. A pair of traditional analog VU meters with separate peak indicators is used for output metering. Both XLR and 1/4" outputs are fully balanced.
