Doepfer

For each output a scale control is available to adjust the scale of the
output in question. It also limits the max. voltage. With the controls fully
CCW the max. voltage is close to +12V. To limit the voltage to +5V the
controls have to be adjusted to about position 4. I'm not familiar with the
Model D but I don't think that voltages beyond +5V can damage the unit
(without obligation).
