Befaco Crush Delay v3

Circuit-bent PT2399 delay meets VC noise generator

11 HP Eurorack module

Crush Delay is a PT2399-based echo-delay Eurorack module with a special talent for generating noisy, degraded textures through circuit bending techniques. It offers up to 400ms of clean delay at faster rates, but transforms into an advanced voltage-controlled digital noise generator as the time is slowed toward the crush zone. The module features dual VCA inputs, a send/return loop, and three independently gateable crush modifiers for a vast palette of sounds from pristine echo to chaotic drone.

Features

  • PT2399 IC-based echo-delay with up to 400ms clean delay
  • Circuit bending techniques applied to PT2399 for noise generation
  • Three independent Crush modifiers with manual switches and gate inputs
  • Gate input threshold of 3V for each Crush modifier
  • Dual audio inputs: IN (routed to delay and dry/wet) and Return (routed to delay only)
  • Dedicated VCA for IN input with manual In Vol knob and CV input
  • Dedicated VCA for Return input with manual Ret Vol knob and CV input
  • Both VCA CV inputs normalled to 10V so knobs act as attenuators when CV is patched
  • Feedback VCA with manual knob and CV input for controlling delay repetitions
  • Dry/Wet control with manual knob and CV input
  • Time CV input summing to pot position, accepts +/-10V
  • Feedback CV input summing to pot position, accepts +/-10V

Controls & Jacks (22)

  • Crush Gate 1— Gate input for first crush modifier. Threshold 3V.
  • Time
  • Feedback
  • Dry/Wet
  • In Vol— Volume of the main input signal. Acts as attenuator when CV is patched.
  • Ret Vol CV— CV input for return volume control. VCA modulation input normalized to 10V.
  • IN— Main audio input. Signal is routed through input VCA to both delay and dry/wet circuits.
  • In Vol CV— CV input for input volume control. VCA modulation input normalized to 10V.
  • Time CV— CV input for delay time control. Sums incoming voltage to knob position. Expects +/-10V.
  • OUT— Main audio output. Contains the mix of dry input and wet processed signal controlled by dry/wet knob.
  • Dry/Wet CV— CV input for dry/wet balance control. Sums incoming voltage to knob position. Expects +/-10V.
  • Ret Vol— Volume of the signal present in Return input. Acts as attenuator when CV is patched.
  • Send— Outputs the fully wet (processed) signal from the delay circuit.
  • Crush Switch 1— On/Off switch for first crush modifier. Can be activated manually or via gate input.
  • Return— Secondary audio input. Signal is summed with main input and routed only to delay circuit.
  • Feedback CV— CV input for feedback control. Sums incoming voltage to knob position. Expects +/-10V.
  • Crush LED 1
  • Crush Switch 2— On/Off switch for second crush modifier. Can be activated manually or via gate input.
  • Crush Gate 2— Gate input for second crush modifier. Threshold 3V.
  • Crush LED 2
  • Crush Switch 3— On/Off switch for third crush modifier. Can be activated manually or via gate input.
