Specifications

The disting mk4's specifications are as follows:

• Panel width: 4HP
• Module depth: 42mm
• X & Y inputs, A & B outputs
  • Sample rate: 75kHz
  • ADC: 24 bit, THD+N -93dB, Dynamic range 99dB, SNR 99dB
  • DAC: 24 bit, THD+N -94dB, Dynamic range 105dB, SNR 104dB
• Z input sample rate: 75kHz
• CPU: Microchip PIC32MX at up to 50MHz
• Current draw: 51mA on the +12V rail, 19mA on the -12V rail

The front panel is drilled for both Doepfer and Analogue Systems mounting holes (using a 'slot' rather than a single round hole). The power connector is a Doepfer standard 16 way IDC, with -12V furthest from the top of the board.
