Combining a CineMag input transformer, a circuit design with less noise, and more API style gain, the Black Lion Audio B12A MKII Microphone Preamplifier is inspired by the original API 312A. The single-channel mic pre features an Edcor output transformer, a Hi-Z input, switchable phantom power, a switchable 10 dB pad, and a switchable phase reversal switch. The preamp is housed in a 1U, 1/2 rack chassis, and offers up to +70 dB of gain. Input is provided by a balanced XLR microphone input and output is provided by a balanced TRS line connector.
