1. INTRODUCTION
Audiophile Circuits League. -ENVELOPE X3 contains 3 very fast independent ADSR-Envelopes.
There are 2 different time ranges that are switchable. Every Envelope has got an inverted output.
The Gate-Inputs 2 and 3 are normalized to Gate 1.
(For details about normalization, see section 5. CHARACTERISTICS)

3. INSTALLATION
△WARNING
*Always turn the Eurorack unit off and unplug the power cord before plugging the Eurorack power cable.
*When attaching the Eurorack power cable, please be careful not to touch the terminal part.
Connect to the Eurorack's system power supply (+12V) using the supplied Eurorack power cable.
Connect the 16-pin connector to the Eurorack power connector. Connect the red mark on the power cable so that it matches the pin on the (-12 V) side of the power connector.
Connect the 10 pin connector to the shrouded header on the back of the module. The header is protected against reverse-plugging.

ENVELOPE X3 ATTACK DECAY SUSTAIN RELEASE 1 234 2 3 GATES EG 1 OUT EG 2 OUT EG 3 OUT 1. 2. 3. 6 SHORT SHORT SHORT POS POS POS LONG LONG NEG NEG NEG NCLFIG.2 : Front Panel
① "ATTACK" knob
Adjust the attack time.
② "DECAY" knob
Adjust the decay time.
③ "SUSTAIN" knob
Adjust the sustain time.
④ "RELEASE" knob
Adjust the release time.
⑤ "GATE" input jack
Inputs a GATE signal. When using only GATE 1, it is possible to control EG 1, 2, 3 using one GATE signal without inserting cables into GATE 2, 3 (Normalize). (For details, see section 5.CHARACTERISTIC)
⑥ "EG/POS" output jack
It outputs standard envelope.
⑦ "EG/NEG" output jack
It outputs inverted envelope.
⑧ "SHORT/LONG" switch
It is possible to select the operation speed of the envelope from two ranges.
5. CHARACTERISTIC
GATE input 1 is normalized (internally connected) to GATE 2, 3. "Normalization" means that if you are not using GATE 2 and 3, the input to GATE 1 will be automatically duplicated to GATE 2 and 3. In other words, you can control three ADSR from one cable input(See FIG. 3). This feature economizes the need to duplicate signals using external multiple modules.

FIG.3: When using only GATE 1 input (Normalized)
Conversely, when inputs of GATE 1, 2 and 3 are individually plugged in, it is possible to control EG 1, 2, 3 by an independent GATE signal (See FIG. 4).
