Associative Envelope

Associative Quadruple Envelope

Product description

A-envelope is a four independent channels ADSR envelope, with association capabilities.

Association between channels

A-envelope allows to define channel groups, that shares configuration.
This capability makes possible to define polyphonic configurations on the go up to 4 voices, in a simple way.

Each channel allows:

  • Modulate every of the ADSR stages in time or shape (Exp, Lin, Log) independently.
  • Adjust the amount of modulation using the stage knobs when acting as attenuverters.
  • Controlling the duration of each stage from 0 to 20 seconds using the stage knobs.
  • Controlling the shape of attack, decay and release stages.
  • Controlling the level of the sustain stage.
  • Configure the input activation mode as Gate, Trigger or Re-Trigger.
  • Configure the channel in single, loop or auto-loop mode.
  • Configure the BEOS (Begin and/or End Of Stage) outputs for each stage.
  • Trigger the channel manually using the test button.

User interface

The user interface is meant to give a fast and direct access to every feature.

  • Instant visualization of each channel group thru the scale indicators and LED arches.
  • Direct monitoring of the signal and BEOS outputs thru specific LEDs.

Characteristics

Time ranges

Attack:
- The minimum amount of time is 750 microseconds, under this value the stage is omitted.
- The maximum amount of time is 20 seconds.

Decay:
- The minimum amount of time is 750 microseconds, under this value the stage is omitted
and therefore, the maximum voltage for the attack becomes the one defined by the sustain.
- The maximum amount of time is 20 seconds.

Sustain:
- The minimum amount of time is 750 microseconds, under this value the stage is omitted
but the voltage level remains as a reference for the other stages.
- The maximum amount of time is 20 seconds.

Release:
- The minimum amount of time is 750 microseconds, under this value the stage is omitted
- The maximum amount of time is 20 seconds.

Inputs

The ADSR modulation inputs

The ADSR modulation inputs accepts signals from -10 to 10 volts and a bandwidth from DC up to 20kHz.
The attenuverters associated to the inputs can amplify/attenuate the input signal from 0 to x2.

| Parameter | Value |
| ------ | ------ |
| Input impedance | 100kOhms |
| Maximum input voltage | +/- 10 Volts |
| Bandwidth | DC to 20kHz |

Trigger/Gate inputs

The trigger/gate inputs react to pulses of at least 2.5Volts and 20us.

| Parameter | Value |
| ------ | ------ |
| Input impedance | 100kOhms |
| Minimum input voltage | 2.5 Volts |
| Minimum pulse duration | 20uS |

Outputs

The ADSR envelope outputs

The ADSR envelope outputs have a voltage range of 0-10 volts, and a minimum period time of 750 milliseconds using only the Attack stage.
The ADSR envelope outputs are doubled to offer both direct and inverted outputs. Both sets have the same characteristics.

| Parameter | Value |
| ------ | ------ |
| Output impedance | 1kOhms |
| Output voltage | 0 - 10 Volts |

The BEOS outputs

The BEOS (Begin-End Of Stage) outputs have a voltage range of 0 volts when inactive and 10 volts when active.

| Parameter | Value |
| ------ | ------ |
| Output impedance | 1kOhms |
| Output voltage | 0 / 10 Volts |

Power consumption

The power consumption it is been measured with all LEDs on.

The +5V jumper selected (Recommended)

  • +5v = 170 mA
  • +12v = 35 mA
  • -12v = 23 mA

The +12V jumper selected

  • +5v = 0 mA
  • +12v = 245 mA
  • -12v = 23 mA

Protection

  • Protection for human body model electrostatic discharge (ESD) of 2kV.
  • Power connector reverse protection.
  • Protection against power polarity inversion.

Working Temperature

  • Working ambient temperature from -20ºC to 70ºC.

Accuracy

  • The accuracy for all specified values is < 1%.

Dimensions

  • 22HP
  • 3U
  • 38mm depth from the back of the panel to the power connector, including the connector.
