Not to be confused with the TMC, the TSC uses optical gain control and has 4 tubes for gain staging and amplification. This makes it very flexible and can be made to sound clean or warm and remain gentle either way. It's fast, certainly mastering grade and can be ordered with Elma gold switches (which I like a lot).

The Fairman TSC Tube Stereo Compressor is a very high quality and warm sounding Tube Amplifier, were the gain is controlled by the light-sensitive input potentiometer.

The circuit design is based upon an LED illuminated high-speed resistor. This light-sensitive resistor is in fact part of an optical controlled potentiometer rather than a VCA. The result is absence of any distortion in the gain-controlling device at any compressor/limiter level. The Tube amplifier does not change gain, and therefor does not change Sound during compression. Compare it to as the compressors “moving Fader”.

The unique developed detection circuit delivers a clean and very fast control voltage to the optical device. This avoids the often seen problem of many comps, where the compressed low frequencies are “modulated”, especially when fast attack and release times are used. The benefit therefor is the extremely high linearity and thigh sound also at the lowest compressed frequencies.

Besides being a Compressor, the Fairman TSC is also a very high quality Tube Amplifier recommended as Recording Input Amplifier.

With its gain range of +/- 15 dB and when the Threshold is set at zero, the Fairman TSC provides the Level Adjustment Facility for many different analog sources before going on track. The Fairman TSC will also with excellent result “Warm Up” on all ready-recorded material.
