Pack your rack with the sound of '73
With its design inspired by a legendary vintage British console microphone preamp, the 1073, the Black Lion B173 Quad packs a huge punch, delivering the muscular bass, assertive mids and bright highs characteristic of a vintage 1073 in an affordable 2RU unit. The B173 Quad features high-quality parts and Class A discrete circuitry with transformer-coupled input and output stages. With 70dB of gain on tap, the B173 Quad delivers large helpings of low-noise headroom. Now you'll finally be able to use your low-output ribbon microphones on quiet sources! The B173 Quad conveys a bold sonic assertiveness that reinforces any signal you pass through it. This is the sound that launched a thousand hits.
Big iron upgrades and more
The B173 Quad is a 4-channel version of the company's single-channel model. More than just another 1073 clone, the B173 Quad combines vintage-inspired sounds and modern features in a rugged 2RU chassis with a smart feature set that will satisfy the most discerning audio engineers. A revised gain stage and lower noise floor deliver cleaner sound with less distortion, while CineMag input and output transformers keep things warm, creamy, and robust. Two front-panel DIs bring harmonic richness to guitars, basses, and synths, while stepped input gain and variable output attenuation give precise 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 its ranges. Here we dig the Black Lion B173 Quad. It's an incredible value and sounds great. Mount one or two of them on your rack and get to work.
