The 511 D DUAL ENVELOPE GENERATOR module in typical ADSR-Style with four parameters: attack time, decay time, release time and sustain level.

The time parameters range from 1 ms to approx. 20 seconds. A gate button allows for manual triggering both envelopes. Trigger threshold of the gate input is ca. 1 volt, positive edge.
Two LEDs serve as indicator lamps
for ’gate pulse present‘. 2 x 4 more LEDs light up during each stage of the envelope.
The envelope outputs serve as normal (0 to 10 volts) and inverted
(0 to -10 volts) outputs.
Both envelopes are switchable from “Normal” to “Retrig” Mode
