Robots Are Red Sump Pump

Stereo gate, noise suppressor, compressor, and expander.

6 HP Eurorack module

A stereo dynamics processor that uses envelope detection and an adjustable attack/release envelope for gating, suppression, compression, expansion, and unconventional level shaping.

Features

  • Envelope-controlled stereo dynamics with adjustable Attack and Release.
  • Threshold spans approximately 0 V to 8 V.
  • Floor ranges from extreme suppression through unity to gain expansion up to approximately +10 dB.
  • Level provides overall output adjustment and makeup gain.
  • Stereo input and output with left-input envelope detection and mono sidechain operation.
  • Engage accepts a gate for manual envelope activation.
  • Dedicated CV inputs offset the Threshold and Floor knob settings.
  • Duck derives an inverted level-control envelope from pulses, triggers, audio, envelopes, or other modulation signals.
  • ENV OUT provides the full-voltage envelope independently of the Floor setting.

Controls & Jacks (15)

  • IN-L— Left audio input; it also feeds the envelope follower that controls the stereo dynamics response.
  • Engage— Gate input that manually engages the attack/release envelope.
  • Floor CV— Control-voltage input that offsets the Floor knob setting.
  • Floor— Sets the engaged gain from approximately -100 dB through unity to +10 dB, enabling suppression or expansion.
  • Threshold CV— Control-voltage input that offsets the Threshold knob setting.
  • ENV OUT— Outputs the full-voltage attack/release envelope independently of the Floor setting.
  • Level— Sets the overall output level and can provide makeup gain.
  • Threshold— Sets the detection threshold from approximately 0 V to 8 V; Gate mode responds below it and Comp mode responds above it.
  • Attack— Sets the rise time of the dynamics-control envelope after it is engaged.
  • Release— Sets the fall time of the dynamics-control envelope after it is released.
  • IN-R— Right audio input; use this input for the mono program signal when IN-L is serving as a sidechain input.
  • OUT-L— Processed left-channel audio output.
  • OUT-R— Processed right-channel audio output.
  • Gate/Comp— Selects Gate mode, in which the envelope engages when the input falls below the threshold, or Comp mode, in which it engages when the input
  • Duck— Envelope-follower input that applies an inverted envelope to the signal level for ducking; it accepts pulses, triggers, audio, envelopes, an
