Module Size: 2 unit space The M 511ac QUAD GATE DELAY combines four voltage controlled gate delay circuits in one module, which delay the incoming gate signals in a range from ca. 1 ms up to 20 seconds. Each delay unit hat its own pair of display LEDs. The four gate in/outputs are internally connected like this: Output 1 goes into input 2, output 2 goes into input 3 and output 3 goes into input 4. This allows complex delay combinations without external patching. The ‘Manual Gate’ button affects delay input 1. The time control voltage inputs are “chained“: i. e. a control voltage in the input 1 jack controls the inputs 2/3/4 as well, if there is nothing else patched. (Input 1 is internally connected to +10 volts if nothing is patched). Control range 0-10 volts, higher control voltages give longer delay times.
