QUICKSTART GUIDE
Meet the Black Lion Audio B173 mkII — the most portable 1073 British sound around! The B173 mkII uses the same Cinemag input and output transformers as our B173 Quad for a whopping 70dB of gain, a revamped gain stage, and a lower noise floor for cleaner, lower distortion sound. A front panel D.I. delivers a harmonically rich tone to guitars, keyboards, and synthesizers, and stepped input gain and variable output attenuation allow for perfect control over transformer saturation.
- Power Switch: This turns the unit on and off. (Note: there’s a 2-3 minute “warm up” time for lowest distortion)
- Gain: This control operates the amount of gain provided by the preamp.
- 48V Button: Engage to turn on 48V phantom power.
- Phase Invert Button: Engage to adjust input signal polarity by 180°.
- 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).
- Hi-Z Button: Engage this to use the Hi-Z Input as the input source.
- Hi-Z Input: Input jack for use with high-impedance, unbalanced sources (Output Level knob adjusts signal amplitude).
- XLR Inpu t: Balanced mic-level input.
- TRS Output: Balanced line-level output.
- Ground : Optional internal chassis ground.
- Power Input: 24VAC input jack (Note: only use a BLA-specified power supply).
