A different kind of dynamics processing
 The S com4 provides four channels of dynamics processing with an expander/gate and compressor/limiter on each channel. The four channels operate independently or in stereo pairs.
 The compressor/limiter section of the S com4 includes variable threshold, ratio and output levels. The expander/gate section features a continuously variable threshold control as well as a switch for fast or slow release times. An enhancer switch restores high frequencies that are sometimes diminished by heavy compression.
 Multi-segment LED metering on the S com4 displays input/output level, as well as gain reduction. Balanced inputs and outputs, with +4dB or -10dBV operation allows the unit to interface into any professional environment.
 Features
 - Four channel compressor/limiter, expander/gate with enhancer
