Become A Master Of Time With The 4ms Company QCD Quad Clock Distributor Module

Four channel voltage controlled Clock Divider/Multiplier with master Tap Tempo. Each channel can be synced to the tap tempo, to the channel above, or to an external clock. Each channel also has a reset jack. With a Tap Tempo button and five sync'ed clock outputs, the QCD is a versatile head-of-the-chain "Master" clock module, and/or a complex rhythmic pattern generator.



  • Four CV-controlled Clock Divider/Multipliers
  • Tap tempo button and five sync'ed clock outputs make the QCD perfect for head-of-the-chain "Master" clock module
  • Tap clock output runs at the tapped tempo (even if other channels are being clocked externally)
  • Create complex rhythmic patterns by patching multiple channels into each other's Div/Mult CV and Reset
  • Each of the four channels has an independent clock IN, OUT, Reset and Div/Mult CV
  • Divide or Multiply incoming clock from /32 to x16 on each channel:
  • Detented knob to snap to integer division/multiples
  • CV jack to modulate Div/Mult amount
  • Reset jack (per channel) restarts the clock when a trigger is received (alters phase of clock)
  • Clock input jacks are normalized downwards: Tap->Red->Black->Blue->Green
  • Clock outputs stop automatically when incoming clock stops
  • LEDs blink to output clocks' tempos
  • 5V clock output pulses, fully buffered. Default is square-wave, and PW is controllable with expander
  • Daisy chain multiple QCDs or other clock modules using Tap Out jack
  • Header on the PCB to connect to Quad Pingable LFO (QPLFO) to provide four CV Skew-able, CV Div/Mult-able envelopes
  • Interfaces with QCD Expander for more features (Pulse Width, Inverted Gate, attenuverters for CV inputs)


MODULE SIZE:

  • The QCD is 10HP and 1.0 inches (26mm) deep.
  • All pots have a metal shaft and nut.

POWER CONSUMPTION: A jumper selects using +5V from the power supply, or generating +5V on-board from the +12V rail.

  • +12V rail: 48mA with jumper selecting external 5V, 88mA with jumper selecting internal 5V.
  • +5V rail: 41mA with jumper selecting external 5V, not used (0mA) with jumper selecting internal 5V.
  • -12V rail: 40mA
