The B12A MKII 500 packs the same punch as its 1⁄2 rack cousin, but in the convenient and flexible 500 series format. The API®-style design features a delicious Cinemag input transformer, serves up huge portions of low-noise gain, and has the same classic American rock sound that the original API® 312A is known for! Get ready to fill your lunchbox®, ‘cause once you go Black Lion Audio, you never go back!

Front
GAIN: clockwise rotation yields an increase in output signal amplitude, counterclockwise rotation yields a decrease in output signal amplitude
48V: engage to turn phantom power on, disengage to turn phantom power off
PHASE (Ø): engage to adjust input signal polarity by 180°, disengage to leave input signal polarity unchanged
PAD: engage to reduce input signal amplitude by 18dBu, disengage to leave input signal amplitude unchanged
Hi-Z: engage to use front panel Hi-Z IN as preamp source, disengage to use 500 series rack’s XLR input as preamp source
Hi-Z IN: input jack for use with high impedance, unbalanced sources (GAIN knob adjusts signal amplitude)
