A-140-2 Dual Mini ADSR

A-140-2 Dual Mini ADSR

Doepfer A-140-2 - Dual Mini ADSR

The A-140-2 contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge / discharge curves of a capacitor) behind a front panel with 8hp only.

Each ADSR provides these controls and inputs / outputs:

•           LED: displays the envelope output

•           A: manual Attack control

•           D: manual Decay control

•           S: manual Sustain control

•           R: manual Release control

•           Gate Input: min gate level: +5V, max gate level: +12V

•           Retrigger Input: min retrigger level: +5V, max retrigger level: +12V

•           CVT Input with attenuator (CVT = CV Time)

•           Envelope Output 1: normal envelope output

•           Envelope Output 2: selectable between normal and inverted envelope by means of an internal jumper

The output voltage range for each envelope is 0 - 10V (10V = attack peak). The time range of Attack / Decay / Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question). Another jumper is used to set output 2 to normal or inverted envelope. And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR #2 is also triggered by Gate 1). Two more jumpers are used fr the optional bus access to the gate signal of the bus for each ADSR.
