The BCL20 from LA Audio is a dual channel, broadcast quality compressor/limiter, that can function in link mode for stereo processing, or as two separate mono compressors. Each channel features complete control over threshold, ratio, attack, release and gain make-up, and provides instant de-essing with the press of a button.
The de-essing function adds a filter into the side-chain, making the compressor "frequency conscious" at the frequency where sibilance occurs. Sidechain access is also provided per channel, in the event where additional EQ dependent compression is required.
A unique feature of the unit is the ability to change the detection characteristics of the compressor, with a choice of Peak and RMS levels, together with a blend of both. Although not a fixed rule, RMS detection is generally used on individual tracks, while Peak detection is more suitable for program compression.
Each channel has two high resolution twelve segment LED meters, one that displays gain reduction, while the other can be switched to display input or output level. The I/O meter can be switched between Peak or VU response.
The BCL20 is equipped with high impedance balanced inputs and transformer balanced outputs. The transformer based outputs feature Active Distortion Cancellation circuitry that reduces to negligible levels, the LF distortion inherent in passive transformer designs. The unit is well suited for broadcast applications, disc mastering, studio and live PA use.
