Black Lion B12AQUAD 4 Channel American Console Microphone Preamp/DI w/ CineMag Its design inspired by a legendary vintage American console mic preamp, the API 312A, the B12A Quad four channel microphone preamplifier packs a massive punch. With its transformer-coupled input and output stages and 70dB of gain on tap, the B12A 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 B12A Quad imparts a bold sonic assertiveness that beefs up any signal you pass through it. The B12A Quad is a 4-channel version of the legendary single-channel B12A Mk2. More than just another 312A clone, the B12A Quad combines vintage-inspired sonics and modern features in a rugged 1RU 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.
