Chicago-based Black Lion Audio started off as modifiers of vintage audio equipment. They decided to channel their knowledge and experience into producing their own boutique hardware, becoming one of the hottest names in the business. The B12A offers the burly yet dynamic American rock sound in a single-channel enclosure. Heres what Black Lion say: What happens when you take the stately B12A and add some extra special sauce? You get the B12A MKII! With a titillating Cinemag input transformer, less noise, and more API-style gain than ever before, the B12A MKII will sweeten your preamp collection for years to come! Inspired by the classic American rock sound of the original API 312A, the B12A MKII delivers the high-end sound and rugged quality youd expect from B.L.A., at an amazing price! The B12A MKII is a single-channel microphone preamp in the style of an API 312A, and features an upgraded input transformer, higher gain, and lower noise than the original B12A. It also features an output transformer, a Hi-Z input, phantom power, pad, phase, and is housed in a 1U, 1/2 rack chassis.
