AM1046 Quad Env Gen

16 HP | AM1046 QUAD ENV GEN | User Manual (PDF) | ModularGrid | You Tube

The AM1046 is a 16HP module that replicates the original Quad Envelope Generator module from the ARP 2500. 

DESCRIPTION The module contains two DADSR and two ADSR envelope generators, just like the original. The DADSR are in the middle positions, and have TRIG and GATE inputs, as well as the normal output (0V to +10V). The ADSR's has front panel space for the inverted output in addition (0V to -10V). 

The duration of the envelope times can be adjusted with the blue locking switch from the standrad time to one 6x times slowwer. The time switch is shared between the left DADSR and ADSR. 

The envelope generators are activated either by a Eurorack gate signal connected to the GATE input jack socket or by pressing the momentary push button. A red LED within the button indicates when the envelope generator is active (prior to the Release cycle). 

The Trigger input for each Env Gen is normalised to the respective Gate input, which makes the originals single/multiple toggle switch redundant, which saves panel space. Normalisation was not possible on the ARP 2500, as it used matrix switches.

CONNECTIONS There are fourteen 3.5 mm jack sockets on the AM1046, with each channel having these outputs and inouts.

• GATE - Eurorack friendly gate ON/OFF signal 
• TRIG - Eurorack friendly pulse (5V p-t-p) 
• OUT - control voltage (0 to +10V) 
• INV - inverted control voltage (0 to -10V) ADSR ony

High quality Alpha potentiometers, and Rogan RB67 knobs have been used to ensure control voltages can be easily set and adjusted.

The module comes with a set of M3 mounting screws and washers, and a standard 16-way Doepfer power cable.
