The B12A Quad from Black Lion Audio is a four-channel microphone preamplifier with 70dB boost including solid vintage sound. Packaged in a robust 1U housing, the user has features such as phantom power, polarity reverse, 18dB pad circuitry and hi-Z switch. The redesigned gain stage and lower noise level provide cleaner sound with less distortion, while CineMag input and output transformers keep signals warm and punchy. Two D.I.'ss on the front give guitars, basses and synthesizers harmonic richness, while the stepwise input gain and variable output attenuation allow precise control over transformer saturation. The metering per channel indicates how hot your output signal hits the parallel TRS/XLR outputs, while an external power supply keeps the noise away from your tracks.
