RP220 Dual Tube Mic Preamp

Bellari » Signal Processors »

Our most popular tube mic preamp. It has been included on several album credits and is present in most major studios in LA, Nashville, and New York. It has the smooth yet punchy characteristics that drive vocal tracks to the front, warm up any digital mix, and yields up to 6 dB more gain before feedback for the live user. The pristine sound is achived by running the tubes at a high 250 volt plate voltage.
