Black Lion Audio B173, Preamplifier - 1 Channel
The B173 is Black Lion Audio’s homage to the highly revered 1073 mic pre. The B173 is a single channel mic preamp with input and output transformers, stepped gain, output level control, phantom power, and phase. It features a DI, 80dB of gain, and is housed in a 1U, 1/2 rack chassis.
- POWER: flip switch up to turn preamp on (there’s a 2-3 minute “warm up” time for lowest distortion), flip switch down to turn preamp off
- MIC GAIN (stepped, 12-position switch): clockwise rotation yields an increase in input signal amplitude, counterclockwise rotation yields a decrease in input 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
- OUTPUT LEVEL: clockwise rotation yields less attenuation, counterclockwise rotation yields more attenuation (for beginners, it’s best to leave the output level fully clockwise and increase Mic Gain as needed so as not to saturate the input transformer)
- DI: engage to select front panel TS jack as input source, disengage to select rear panel XLR jack as input source
- OUTPUT: balanced, line-level TRS output
- INPUT: balanced, mic-level XLR input
- GND: internal chassis ground
- POWER: 24VAC input jack (only use a BLA-specified power supply)
