Soundtronics ADSR 3310

The ADSR 3310 is based on the AS3310 chip with the following features:

  • 1mS to 30 second Attack, Decay, and Release times.
  • Re-trigger input permits retrigger of the attack phase during the decay period
  • Supply voltage +/- 12V as standard, change 6 resistors for +/- 15V operation
  • Range switch offers finer adjustment for short timing periods
  • Comparator on gate input making it suitable for gate pulses >2.5V
  • Manual gate switch
  • Twin ADSR outputs
  • PCB suitable for 4 types of power supply connector - Soundtronics, Eurorack, Dotcom and MOTM
  • Full 10V swing on ADSR output
  • Optional JST leads for all connections although you can hardwire if you prefer

See the 'Build Guide' tab on the PCB product page for build guidance.
