Module Installation

  • To install your 2hp module, locate a space with the appropriate HP in your rack for installation.
  • Next, connect the module’s power cable to your power supply.
  • The cables on this end are keyed, though you should make sure to align the red stripes on both connectors to ensure safe and proper connection.
  • Our illustration uses a flying bus cable, though the same action applies for busboards/alternate power solutions. See the figure below for reference:
  • Next, make sure your module’s power cable is properly connected to your module.twohp-2hp-ADSR-4-Stage-Envelope-Generator-fig-3
  • For 2hp modules, confirm that your cable’s red stripe aligns with the white marker line on the module’s PCB, just above the power header.
  • You may notice that even though there is only 1 row of 5 pins on your 2hp module, but 2 rows on the power cable.
  • You can use either row of 5 pin connectors on the cable with your module, so long as the red stripe is properly aligned. See figure below for reference:
  • Finally, mount your module to the rails using appropriate mounting screws. Your module is now ready to be powered on and patched!

FAQs

Q: How do I trigger the envelope event?
A: Use the Gate Input to trigger the envelope event. The Sustain stage is held while the gate signal is HIGH. Increase the gate length for longer sustains!
