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
