About this listing
The Purple Audio Biz MK 500-Series Preamp is a unique sounding, three amplifier, discrete microphone preamp module designed to work in standard 500-Series 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 Purple Audio's Class A, discrete 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. The Biz uses two KDJ3 opamps and one KDJ4 opamp.
