Doepfer A-140-2V Dual Mini ADSR Envelope Generator (Vintage Edition)

Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.Each ADSR provides these controls and in/outputs:

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).Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.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 for the optional bus access to the gate signal of the bus for each ADSR.Changing the positions of the mentioned jumpers allows to modify the factory settings.
