Pulling from the tech of fully-balanced transformerless circuitry found in a variety of other lauded recording consoles, the Black Lion Audio Auteur is a 2-channel mic preamp that uses a similar high-speed configuration. Each channel comes equipped with accoutrements like polarity inversion, +48v phantom power, and a 10dB output signal pad. This half-rack mic pre is powered by a Triad wall-wart power supply and can be linked up with another of Black Lion's half-rack pres to get a full-sized rack.
