Quad signal or CV switch
This module is designed to replicate the (slightly obscure) Roland 100m Signal Gate module, M-173.
The module comprises four analogue switches, each having a positive and negative control input.
The circuit keeps the original Roland circuitry for processing the control signals, but uses a DG412 analogue switch IC for the signal switching, replacing and simplifying the discrete circuitry in the original Roland unit.
The module includes two multiples. The lower multiple is commoned to the upper multiple if the lower left jack socket is not used.
Specification (measured values):
- Positive switch voltage: 1.2 Volts
- Negative switch voltage: 1.05 Volts
- Feedthrough, input to output with switch off (±5V 1kHz sine input): ±1.5mV
- Crosstalk, input to other outputs, with all switches on (±5V 1kHz sine input): ±0.25mV
Black FR4 or silver aluminium panel options.
