Gyraf Audio Gyratec III Stereo Electro-Optical Compressor

Gyraf Audio Gyratec III Stereo Electro-Optical Compressor is a true tube stereo compressor based on the opto VCA principle.

Gyraf Audio Gyratec III Stereo Electro-Optical Compressor Details

Gyraf Audio Gyratec III Stereo Electro-Optical Compressor is a true tube stereo compressor based on the opto VCA principle. This method - controlling the gain by the means of a light dependent resistor - is not as fast as the vari-mu method, but much more subtle sonically. This principle is known from eg. the classic Universal audio LA2, LA3 and LA4 compressors.


Gyraf Audio Gyratec III Stereo Electro-Optical Compressor is floating, transformer balanced in and out. Input impedance is greater than 10 kilo ohm while output impedance is less than 1 kilo ohm. Gyraf Audio Gyratec III Stereo Electro-Optical Compressor is based on SRPP gain stages with no feedback, using selected 5814 dual triodes for both input and output stages. These tubes are still fairly easily available today.


Although semiconductors and opamps are used in Gyraf Audio Gyratec III Stereo Electro-Optical Compressor, they're confined to powersupply and sidechain functions. At no time will your audio pass through anything but transformers, tubes and passives.


Gyraf Audio Gyratec III Stereo Electro-Optical Compressor Features


  • A true tube stereo compressor based on the opto VCA principle
  • Floating, transformer balanced in and out
  • Based on SRPP gain stages with no feedback, using selected 5814 dual triodes for both input and output stages
  • Audio passes through transformers, tubes and passives only
  • Input level pot is positioned right after the input transformers, thus allowing you to control the input level, the "drive" for the compressor
  • Threshold pot controls at what level the compression will set in
  • Ratio pot controls the amount of compression in relation to changes in the input level
  • Attack pot controls the time the compressor takes to react to a rising input level
  • Release pot controls the amount of time it takes from the input signal falling below threshold, to the gain reduction being returned to unity
  • Output level pot controls the signal level to the output driver stage and the output
  • Bypass switch bypasses the unit completely
