Inspired By Neve's Legendary 1073 Design - The Black Lion B173 Single Channel Mic Preamp

The B173 is Black Lion Audio’s homage to the highly revered Neve 1073 mic pre. The Black Lion B173 is a single channel mic pre-amp with input and output transformers, stepped gain, output level control, phantom power, and phase. It features a DI, 80dB of gain, and is housed in a 1U, 1/2 rack chassis. Don’t let the price tag fool you. This is not only a serious contender for the most “bang for your buck” preamp in existence, but sonically stands on its own at any price point.
