Overview:

The Samson S com4 is a compact and versatile single-rack space device that provides four channels of high quality dynamics processing with an Expander/Gate and Compressor/Limiter on each channel.

• The four channels operate independently or in stereo pairs. Its multi-segment LED metering displays input/output level as well as gain reduction.
• The Expander/Gate section features a continuously variable Threshold control as well as a switch for fast or slow release times.
• The Compressor/Limiter section includes variable Threshold, Ratio and Output levels. S com 4's Enhancer switch restores high frequencies that are sometimes diminished by heavy compression.
• This wide-ranging combination of features makes the S com 4 an efficient and versatile audio tool for a wide variety of applications. Its clean and quiet audio characteristics make it ideal where high sonic integrity is imperative.
