Following on from the huge success of the DRS-2, 2 – channel microphone pre-amplifier/DI, Phoenix Audio have released the single channel, half rack-width, mono Pre/DI. The DRS-1 Mic-Pre/DI uses our well proven and loved Class A output stage (DSOP-2), but also has our latest breakthrough in transformerless Class A, Discrete Mic Input Technology which gives a “valve-like” sound. It also incorporates our high input impedance DI circuitry.Specifications1U half rack space unit: With 240V/110V mains voltage input selector switchClass A (DSOP2) Output specs.
