Dynamics Toolbox

A fantastically flexible dual channel/stereo linkable compressor with a choice of compressor sidechains for tracking, mixdown and mastering.  Built in 'New York' style parallel compression for thickening up stereo subs, especially drums or guitars.  Full sweepable side chain filtering on board plus balanced sidechain insert points.  Illuminated VU meters.  A truly flexible compressor for studio or live use.

 

Use it in peakride mode when tracking vocals or anything else which needs the best tracking compressor available.  Switch to dynamics tracking for mixdown and mastering.

Compressor

  • Threshold range : 18dBu to -30dBu
  • Attack Time ('peakride'): 60ms to 1ms

  • Lo pass filer : 1.3kHz to 15kHz, 12dB per octave

 

Blend Function ('New York' compression)

  • Blends output signal between unprocessed (dry) and processed (wet) audio

 

Metering

  • Switchable between audio input, audio output and gain reduction.
  • 0VU switchable between +6dBu and +18dBu

 

Bypass function

  • Relay switching of audio input jacks to audio output jacks bypassing all unit electronics. Auto-bypass when power is off.
