Black Lion Audio's B12a was inspired by the classic 'American' tone of the API 312a and delivers similar high-end rock sound. Since the original Mk1, Black Lion Audio have upgraded the B12a's internal transformer to provide more gain and even lower noise.

Sporting 48v of phantom power, pad, phase reversal and a even hi-z input, the B12a Mk2 is a great pick for both mics and instruments.
