"Recording artist and musician and Robert Lanois designed the BL99 4‐channel Mic Preamp with the professional user in mind. As a result, the performance of the BL99 is unmatched. The unit is virtually hiss‐free while harmonic distortion is almost too low to measure. The sound is very robust and holds up under wild equalization. There is no mid‐range fog or harshness, as with other pre‐amps, while the entire mid‐range is well defined and allows for a whole new experience in the studio. The top end is smooth with “air” but no roughness and extends easily beyond hearing range. You’ll experience no bumping at around 8k or lack of air and headroom is exceptional."
