Module A-185-1 was designed in 1997 and at this time there were no other (or only a few) other module manufacturers on the market.
The gate section of the A-185-1 is only a buffer (nothing but a so-called emitter follower) but does not increase the gate voltage.
Rather the emitter follower lowers the voltage a bit (by about 0.7V). The A-185-1 was designed to be used with A-100 modules only
and for A-100 modules there was this rule for gate voltages: <1V means low and >3V means high. All A-100 modules that process gate
signals (especially envelope generators, clock divider, trigger delay and so on) have usually a transistor at the gate input that
requires about 1.5-2 V to trigger. But I'm aware that things have changed and we will redesign the A-185-1 so that the gate output
voltage can be set to +5V or +12V (probably by means of a jumper) and that it does no longer work as a buffer.
