In the REVO SC-2 preamplifier, a pure and elegant style combines with the most refined technology. Completely remote-controllable in all its functions, the REVO SC-2 model uses the exclusive P.D.D.A. (Programmable Digital Analogue Attenuation) volume control. It a system that attenuates between 0.0 dB and -127.0 dB in steps of 0.5 dB, with a  typical precision of +/- 0.01 dB.
