The Purple Audio Biz Mk is a unique sounding, three amplifier, discrete microphone preamp module designed to work in standard "500" racks.

The smooth Gain control helps you dial in the sound you want. If the output level is too high (the Class A/B output opamp can pump out up to +27 dBu), you can ride the level down with the separate Level control. Pressing the "Dual" switch splits the gain between two of our Class A opamps, enabling up to 75 dBu of clean gain, making the Biz a perfect match for ribbon microphones.

With different Gain, Level, and Dual settings the Biz can produce an infinite variety of tonal variations with the same amount of output level. The front panel DI helps you record instruments and line level sources with unrivaled clarity and punch. Two LEDs clearly indicate signal level for the gain and output stages at a glance, turning green to indicate signal present, yellow for 10dB below clipping, and red for clipping.

For easy serviceability and tweaking, the Purple discrete opamps can be replaced with any standard discrete opamp or a DIP-8 IC. The Biz uses our custom output transformer which provides two isolated outputs (when supported by the chassis).

The Purple audio Biz Mk, the same Biz you love with two new features:
  • Mic / Line switch for rack input
    Bridging line input for high output mics or line level sources Use with our Moiyn 8x2 mixer module in the Sweet Ten rack for mic or line mixing
  • DI Load switch for front panel input 33kohms as in the original Biz or 100kohms for a more open tone
