This is a 1046 which is basically a 1003 + 1033.
Used to produce repeatable CVs of 0 to +10V & 0 to -10V.
ARP 2500 EGs have both Gate & Trig inputs (G & T).
The G & T inputs can be found at both the top & bottom of the module.
The Gate is an on/off signal with duration.
The Trigger is more of an sharp impulse with no duration.
This is a really cool feature. If you apply another trigger signal while the gate is still present the cycle
will restart. ..a good way for creating multi-peak envelopes.
There are 4 main adjustable parameters : Attack Time, Initial Decay, Sustain, Final Decay (Release).
and two Delay time pots that are used when in multiple mode (arranged in four vertical rows
of 4 pots, 5 pots, 4 pots, 5 pots).
The Delay time feature permits the user to delay the attack of an envelope (3 milliseconds to 3 seconds).
When the Trigger Mode switch is in the Multiple setting you need both gates & triggers to activate an envelope. In the single mode, only a gate is required (T not needed).
If the gate is suddenly removed in the middle of a cycle the voltage returns to 0V
