Quad ADSR A-143-2

3. Controls, Inputs and Outputs

G :

gate input

Rt :

retrigger input

Socket ! is the ADSR’s gate input, socket

the retrigger

input. The detailed function of these inputs is described on
page 2.
The gate inputs of the units 2…4 are normalled to the gate
input of unit 1. If one common gate signal has to be used for
all four units this signal has to be patched into the gate input
of unit 1. As soon as a plug is inserted into the gate input 2,
3 or 4 the default connection is interrupted for the unit in
question.
The retrigger inputs are not normalled.

Range :

range switch low – high – medium

Attack :

attack control

Decay :

decay control

Sustain :

sustain control

Release :

release control

These controls define the ADSR shape. The rotary controls

and

are used to adjust the attack time, the

decay time, the sustain level and the release time. The
range switch

is used to select one of three time ranges

for the time controls attack, decay and release. The
meaning of attack, decay, sustain and release is described
in detail on page 2.

ADSR Out:

envelope output

envelope display (LED)

Socket

is the output of the envelope generator. The

envelope voltage ranges from 0 to about +8V. The envelope
signal is displayed with the LED

End of A :

end of attack output

End of D :

end of decay output

End of R :

end of release output

These are three digital outputs that indicate the end of the
attack, decay or release phase. As soon as the criterion in
question is valid, the corresponding digital output turns
"high". The three digital outputs are described in detail on
page 2. The output levels are about +10V.

These outputs can be used to trigger other A-100 modules
(or another unit of the A-143-2) synchronized to the ADSR
envelope generated by the A-143-2.
