500 Series Stereo Toolbox

The ultimate 500 Series stereo bus compressor that does so much more than any of its competitors.  Dual mono!  Stereo linked!  Mid/Side compression!  Stereo Width control!  Sweepable Side-chain filter!  Cinemag Steel Core Output Transformers!

 

This is the flexible toolbox of 500 Series compressors that can track when required to, fantastic across the 2-buss, and all the way into mixdown and mastering duties.  Perfect for those needing a high end compressor for all stages in the recording and production process.

 

Check out the great features below.

Physical

  • Size : API™ 500 Series dual module compatible (76mm wide by 133mm high by 150mm deep)
  • Weight : 1.14kg (2.5lbs)
  • Power requirements : ±16 volts dc at ±230mA to the standard API 500 Series pin-outs.
  • Fusing : On board 'auto reset' polyfuses protecting the ±16V rails

 

Main processor audio path

  • Frequency response : -0.25dB at 10Hz, -0.5dB at 70kHz
  • Distortion (on board selectable to low or high coloration)

       Low color : 0.06% up to 500Hz, < 0.02% at 1kHz and above

       High color : 0.2% to 1% up to 500Hz, typically 0.04% at 1kHz and above

      (level and frequency dependent)
