Purple Audio Biz Microphone Preamp
This demo Biz is fully functional and in excellent condition.
This unique three-amplifier, discrete preamp sports a Class AB opamp that can muster 27dB of gain, plus a gain pot that lets you get it just right. Hit the "Dual" switch, and your gain splits between two Class A opamps, giving you up to 75dBu of clean gain - ideal for your ribbon mics. If you want tasty coloration, you can dial up quite a palette using different Gain, Level, and Dual settings. There's even a great-sounding front-panel DI on the Purple Audio Biz.
