Stereo Class A Microphone pre-amplifier/DI
Phoenix Audio International (UK) is dedicated to the development of Class A discrete technology used within high build-quality equipment designed for both the professional and the home studio environment.

The DRS-2 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.

The DRS-2 is the culmination of over 40 years experience designing Class A circuitry within the Audio Recording Industry.

The DRS-2 was the first bespoke product to be launched by Phoenix Audio (UK) in the U.K. in November 1999, and has enjoyed an almost cult following ever since. The Class A output stage (TF1) was originally designed by David Rees, the designer of the famous Nevetm 2253 Limiter and 2254 Limiter/compressor (amongst many other designs), as a retrofit for Nevetm modules, and the TF1 has now been superseded by the DSOP2 output stage.

The Class A, discrete, truly balanced, transformerless microphone input stage was designed to out-perform any transformer input for frequency response, yet has all the characteristics expected in a high quality Class A design, while the discrete, Class A, high input-impedance DI stage delivers a clearer, stronger and more defined and open sound that captures all the nuances and subtleties of your instrument.
