Each channel combines an Expander/Gate, a Compressor/Limiter and a fully adjustable
Enhancer. This unique circuit reduces noise, increases loudness and recovers high
frequencies that might otherwise be compromised when audio is heavily compressed.
The Spectra switch adds a mid-band boost to the detector circuit to help smooth
out harsh vocals. The Expander/Gate features a variable Threshold control and switchable
(fast/slow) Release time. The Gate's operation is easily visible with twin (open
and closed) LEDs. The S com's Compressor/Limiter controls include Threshold, Ratio,
Attack, Release, and Output. The Auto function continuously analyzes the audio input,
and automatically adjusts the attack and release parameters based on the changing
level. A Key input and Key Listen feature provides for external triggering, or EQ,
of dynamically processed signals.
