Description: A feedback-type compressor/limiter based on a vintage design.
Notes: Compressor gain is continuously adjusted as a function of the level of the compressed signal
itself, resulting in a response quite unlike that of more recent feedforward-type compressors that
monitor directly the level of the source. Has adjustable lookahead delay (a feature uncommon in
feedback-type compressors) and sidechain EQ.
I/O Characteristics: Stereo-in, stereo-out.

Description: Multiband, adjustable-knee compression. A three-way crossover splits a stereo source
into low, mid, and high frequency bands. Each band gets compressed separately, with its own
threshold, ratio, knee-width, attack, release, and output-level controls. Crossover points are fully
adjustable.
Notes: The crossover is designed such that the sum of the three bands exactly equals the source when
there is no compression and output levels are at 0 dB.
I/O Characteristics: Stereo-in, stereo-out.
