Black Lion B173 Quad Four-Channel Microphone Preamp


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.

 

The B173 Quad is a four-channel mic pre-version of the single-channel model. More than just another 1073 clone, the B173 Quad combines vintage-inspired sonics and modern features in a rugged 2RU chassis with a smart feature set that will satisfy the most demanding audio engineers. A revised gain stage and lower noise floor deliver cleaner sound with lower distortion, while CineMag input and output transformers keep things warm, creamy, and beefy. Two front-panel DIs impart harmonic richness to guitars, basses, and synths, while stepped input gain and variable output attenuation give you exacting control over transformer saturation. Per-channel metering displays how hot your output signal is hitting the parallel TRS/XLR outputs, while an external power supply keeps noise out of your tracks.
