Features

  • PT2399 Delay/Echo
    • The PT2399 is a CMOS single-chip echo processor IC
    • A high sample rate ADC converts the analog data into a bitstream, which is then stored in internal 44Kbit RAM
    • After processing, the bitstream is de-modulated by DAC and lowpass filter
    • The internal VCO clock frequency determines the overall delay duration
    • The user can easily modify the VCO frequency by changing the external resistance
  • Eurorack 3U, 6HP card
  • Built on ER-PROTO-02 card
  • PT2399 has a maximum current of 30mA
  • Jacks
    • J5 IN
    • J6 OUT
  • Controls
    • RV1 In/Out mix
    • RV2 Delay Length
  • 10 pin Eurorack power jack
