Mono Class A Microphone pre-amplifier/DI/EQ
The DRS-Q4M is a 4 Band Gyratory-based Eq with 11 selectable frequencies, and Mic, Line, and DI inputs. We know you will be as pleased with it’s sonic qualities as we are. The DRS-Q4M has the advantages of more than 25 years experience in audio engineering, today’s component and manufacturing technology, but still retaining “that sound” uniquely achievable through Class A design. Phoenix Audio International (UK) is dedicated to the development of Class A discrete technology used within high build-quality equipment. The DRS-Q4M uses our well proven and loved Class A output stage (DSOP-2), but also has our latest breakthrough in transformerless Class A, Discrete, truly-balanced Mic Input Technology which gives a "valve-like" sound. It also incorporates our high input impedance DI circuitry.
