• The ADE-51 is a highly-specced Envelope Generator (EG) with a full Control Voltage (CV) implementation.
• Linear and exponential envelope types are easily selectable via a dedicated front panel button.
• 5-stage AHDSR envelopes (see Page 8) can be generated via the Gate input and 3-stage AHD Envelopes
(see Page 8) can be generated via the Trigger input.
• 5-stage AHDSR envelopes offer both Trigger and re-Trigger functionality by combining the Gate and
Trigger inputs.
• Two simultaneous outputs are available offering a standard ‘rising’ envelope and an inverted ‘falling’
envelope - with no need for additional inversion or biasing stages.
• The Envelope Time control allows manual or CV control over all envelope stages simultaneously.
• The ADE-51 is capable of fast, precise envelope stages - each with a rise/fall time minimum of
1 Millisecond and a maximum of 10 Seconds for the Attack, Decay and Release stages and
a 2.5 Second maximum for the Hold stage.
• The pot responses are tapered to allow for greater precision when dialling in faster envelope times.
• There are two user-selectable pot taper responses - ‘Smooth’ and ‘Sharp’ - which are selected using
a jumper connector on the rear PCB.
• The ADE-51 works with a standard 0-5V CV range on all CV inputs. CV outside of the 0-5V range
will be blocked by the CV input conditioning - but please try to ensure that the CV signals used are
generally within the Eurorack standard.
• The ADE-51 has reverse-voltage protection built in - but please pay attention to the power supply
and connection guidelines on Page 3 of this manual.

3) Rear Connections
RED STRIPE
POWER CABLE
PRECAUTIONS: Only connect the power cable to the power connection as shown.
DO NOT CONNECT THE POWER CABLE TO ANY OTHER PORT!
The ADE-51 uses the Doepfer standard for power connection and cable orientation.
The RED stripe on the supplied power cable connects to the NEGATIVE (-12V) rail
on the ADE-51 with the RED stripe facing DOWN. This is marked on the back of
the ADE-51 PCB as “– RED”.
The ADE-51 has diode and polyfuse protection built in but an incorrectly connected
cable may still cause permanent damage to the module or the power supply.
The rear panel of the ADE-51 has exposed parts and connections. Please ensure
when handling the ADE-51 that the unit is held by the sides of the front panel or
the sides of the PCB (Printed Circuit Board).

1) GATE INPUT
Use a Gate, Trigger or Clock Signal as a Gate input to IN:GATE
2) ENVELOPE OUTPUT
Connect OUT:1 to the Control Voltage (CV) input of a Voltage Controlled Amplifier (VCA) or to some
other CV modulation input.
3) ENVELOPE CONTROLS
Set the ENVELOPE TIME knob to fully counter-clockwise (shortest envelope time) and all other
knobs to approximately 09:00 (pointing left).
The LED at OUT:1 should now be showing that the envelope is triggering.
Adjust the individual controls for each stage of the envelope to achieve the desired envelope
time, shape and sound.

1) IN: ATT. CV
A CV signal at this input enables external control over the time of the Attack stage of the envelope.
ADE-51 CV inputs are designed to take a 0-5V CV signal. CV signals outside of the 0-5V range
(<0V and >5V) will be blocked by the final output of the CV circuit - but please try to ensure that
the CV signals used are generally within the Eurorack standard.
ADE-51 CV inputs work with their associated pot to provide an initial CV bias level. Positive CV
signals are added to and negative signals are subtracted from the initial CV bias level allowing the use
of attenuated, AC and (Low Frequency Oscillator) LFO signals to provide a full range of modulation.
2) IN: HOL. CV
A CV signal at this input enables external control over the time of the Hold stage of the envelope.
3) IN: DEC. CV
A CV signal at this input enables external control over the time of the Decay stage of the envelope.
4) IN: SUS. CV
A CV signal at this input enables external control over the level of the Sustain stage of the envelope.
5) IN: REL. CV
A CV signal at this input enables external control over the time of the Release stage of the envelope.
6) IN: ENV. CV
A CV signal at this input enables external control of the overall time of the entire envelope.
7) IN: GATE [AHDSR]
The Gate input will accept a Gate, Trigger, Pulse, Clock or any positive-going signal with a fast,
rising edge. Any signal of this type at this input will cause the 5-stage AHDSR envelope to generate.
The ADE-51 Gate input uses the standard envelope generation method where the Release stage is
triggered as soon as the input signal goes low.
8) IN: TRIG [AHD]
The ADE-51 Trigger input has dual functionality. When used in conjunction with Gate triggering of
5-stage AHDSR envelopes - it acts as a re-Trigger input, causing the envelope to start
generating again from the Attack stage (see Page 8).
Any re-Trigger signal received after the Attack and Hold stages have completed while the Gate signal
is still ‘High’ will cause the Envelope to re-Trigger from the CV level the envelope was at when the
re-Trigger was received (see Page 8).
Used by itself - it will Trigger a 3-stage AHD envelope that operates independently of the Trigger length.
Here - the Attack time operates normally, the length of the ‘Sustain’ stage is determined by the Hold
control at a full +5V and the ‘Release’ stage of the envelope is set by the Decay control (see Page 8).
9) OUT: 1
Standard envelope output in a 0-5V range.
10) OUT: 2
Inverted envelope output in a 5-0V range.

Linear envelope response is characterised by smooth, even rise and fall times and Exponential
envelope response is characterised by a curved response that ‘speeds up’ over time.
AHDSR is the ADE-51s standard, 5-stage envelope type, generated by a gate signal. A 3-stage AHD
envelope can also be generated using the Trigger input where the time of the total envelope is set by
the length of each stage and is independant of the Trigger/Gate length.
The AHDSR envelope type can be re-Triggered at any stage after Hold. The envelope stages start
again from the Attack stage at whatever level the envelope it is at when re-Triggered. When the initial
Gate signal ends - the envelope enters the Release stage as normal. The AHD envelope type operates
independently of Trigger/Gate length with all stage times set by the relative front panel controls.
