Give Your Mics the Biz

Need a 500 Series mic pre with big-time versatility? Sweetwater has an excellent suggestion: the Purple Audio Biz. 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.

Purple Audio Biz 500 Series Preamp Module Features at a Glance:
  • Discrete signal path
  • Output level control; input and output tri-color LED metering
  • Mic/Line switch for rack input
  • Bridging line input for high output mics or line level sources
  • Load switch for front panel DI: 33kohms or 100kohms for a more open tone
  • Auto-resetting fuse shuts down individual module without affecting entire rack or console
Purple Audio's Biz: great-sounding and amazingly flexible!
