Purple Audio Biz Mk 500 Series Mic Preamp / Line Driver Module

The Purple Audio Biz Mk is a 500 Series mic preamp, DI, and line driver. This is an update to the original Biz of the 2000s which did not have the switchable line section. It features a discrete signal path and a "DUAL" switch, which splits the signal to two separate Class-A amplifiers for up to 75dB of gain.
