Doepfer A-171-4 Quad Voltage Controlled Slew Limiter
Module A-171-4 is a fourfold voltage controlled slew limiter. It's intended purpose isĀ polyphonic portamento but can be used also for other applications where several slew limiters are required. The common slew time can be adjusted manually and in addition controlled by an external control voltage. The moduleĀ uses light-sensitive resistors (LDR). Therefore the slew times are not exactly the same for all units due to the tolerances of the LDRs and the LEDs, which are used to illuminate the LDRs. Inputs and outputs of the slew limiters are buffered to avoid voltage drops. This is especially important for polyphonic portamento applications. Each output can drive several VCOs without the need of exernal buffers. In addition the slew limiter inputs and outputs are available at internal pin headers for internal pre-wiring of polyphonic patches. As the switching contacts of the sockets are used for the internal pre-patching the internal patch can be overridden by using the sockets at the front panel.
- Width: 4HP
- Depth: 45mm
- Power:Ā 40Ā mA +12V / 40 mA -12V
