By default the max. gain is 1. But the VCAs can be modified so that they
amplify (one resistor has to be changed: R17 for both A-130 and A-131). But
with typical A-100 signal levels (e.g. from a VCO) you will reach clipping
very soon as the maximum output swing is about +/-10V with the 12V power
supply of the A-100.
