6.2. Application of A-190-2 and Precision Adder A-185-2
In this application the A-185-2 is used to add up several voltages that are used to control the pitch of all VCOs that are
connected to the same bus board as the A-185-2:
• CV Note is connected to one of the inputs of the A-185-2 without attenuator
• CV Pitch Bend is connected to the input of the A-185-2 with attenuator to be able to adjust the pitch bend width
• CV Ctr is connected to the control input of a VCA (e.g. A-130) and controls the level of the triangle signal of the LFO
A-145. The output of the VCA is connected to one of the inputs of the A-185-2 without attenuator. That way the Midi
controller (e.g. modulation = control change #1) is used for the modulation depth. If the A-145 is replaced by a
VCLFO A-147 the CV Volume of the A-190-2 may be used to control even the modulation frequency of the LFO.
• The CV output of a sequencer A-155 can be connected to the remaining free input of the A-185-2. Then the CV
Note of the A-190-2 is used to transpose the sequence of the A-155 via Midi.
Attention: In this application the bus CV jumper of the A-190-2 has to be removed and the bus CV jumper of the A-185-2
has to be installed ! Otherwise a short circuit between both CV outputs is made !
