Black Lion Audio B173 Quad
The B173 Quad (four channel mic pre) packs a massive punch, delivering the muscular lows, assertive mids, and glossy highs characteristic of a vintage 1073 in a budget-friendly 2RU unit. The B173 Quad features high-end parts and discrete Class A circuitry with transformer-coupled input and output stages. With 70dB of gain on tap, the B173 Quad serves up heaping portions of low-noise headroom. Now you'll finally be able to use your low-output ribbon mics on quiet sources! The B173 Quad imparts a bold sonic assertiveness that beefs up any signal you pass through it.
