Samson S.Com 4 Compressor

Get the exact sound you need, time and time again. Using the Com4 gives you a wide range of tools to affect your sound source. Featuring expander/gate and compressor/limiter on each of the four channels, the S Com4 allows you to control the final sound of your audio with precision. Effortlessly target specific qualities, and attenuating or boost them as you see fit. The expander/gate boasts continuously variable Threshold controls, as well as a switch for fast or slow release times. The compressor/limiter section includes variable threshold, ratio, and output level, whilst the Enhancer switch allows you to restore those precious frequencies that are often lost when heavily compressing material. In short, you’ve got total control of every nuance of your sound.


  • Refine your sound with 4-channel compressor/limiter and expander/gate with enhancer
  • Easy to link in two stereo pairs
  • Go from subtle to obvious effect thanks to an expander/gate with variable trigger control and switchable fast/slow release
  • Prevents distortion with independent threshold and ratio controls on each channel
  • Monitor your levels with precision thanks to a 5-segment LED meter for input, output, and gain reduction on each channel
  • Low noise operation from an advanced circuit design
  • Pristine signal integrity courtesy of servo balanced inputs and outputs on XLR and ¼” connectors
  • Amplifiers and high-quality VCAs
  • Go from soft to hard knee based on the level of the input signal with the Smart Knee Detector
  • Universally fits standard 19” rack units
  • Robust construction prevents damages from knocks and scrapes
