About This Listing

Up for sale, a Black Lion Audio B12A half rack preamp in excellent condition and in perfect working order. Based off the legendary API 312 preamp heard on countless classic studio recordings, the Black Lion B12A delivers that recognizable bold punch. Sporting transformer balanced inputs and outputs, this B12A “MK I” will impart your signal with a harmonically rich character that compliments virtually any source.

The straightforward layout consists of buttons for 48V, Phase, and Pad, on the faceplate, while a single red Gain knob controls the Input signal. A Hi-Z button engages the 1/4“ Hi-Z input, while the back of the enclosure features a balanced XLR input and TRS Line Output.

Cosmetic wear is limited to light rack rash on the sides of the enclosure, while the faceplate is quite clean with just a few scratches and bold silkscreen graphics.
