Black Lion Audio has introduced the B12A MKII, a single-channel microphone preamp in the style of an API 312A.
The MKII version offers an upgraded input transformer, higher gain, and lower noise than the original B12A. It also includees an output transformer, a Hi-Z input, phantom power, pad, phase, and is housed in a 1U, 1/2 rack chassis.
“The original B12A was very popular, but we were continually being asked by customers to modify them for more gain,” commented Nate Bierdeman, director of marketing for Black Lion Audio. “So we created the MKII with higher gain and lower noise. This revision also gave us the opportunity to integrate a nicer input transformer, and has resulted in an incredible-sounding preamp with lots of API-style gain.”
