voltage standards for euro?

terribly n00b question here:

what are the AC and DC signal level standards (inc. triggers) for euro?
i couldnt find it on the doepfer page. thanks!

it's hiding in the "technical details" section:

"Audio Signals are produced by the sound source Modules (such as VCO or NOISE), and lie in the range from -5 V to +5 V (10 VSS). The System A-100 can also let you use external Audio Signals (e.g. Microphone, Electric Guitar, Keyboard).
To interface satisfactorily, the level of external Audio Signals must be brought up to the A-100’s operating level.
Module A-119 (External Input), is ideal for this job, having among other things an internal pre-amp, and two inputs of different sensitivity.
Control voltages, as produced by modulation sources like the LFO and ADSR, are from -2.5 V to +2.5 V (5 VSS) for the LFO, and from 0 V to +8 V for the ADSR.
Trigger or Gate Signals, which start a process or function, are typically from 0 V to 5 V, with the trigger occurring as the leading edge of the waveform shoots up from 0 V to 5 V.
These definitions of the various signals, and the distinctions between them - sound sources and modulation sources - are right in principle, but a modular system like the A-100 often makes a mockery of them. In a modular set-up, all of the modules produce voltages, and can be used as control voltages or triggers, thus blurring the distinction between the various types.
For example, the output from an LFO can be used as an audio signal, as a control voltage for a VCF or VCA, or as a trigger signals for a sequence.
It’s just about true to say that anything can be modulated by anything else, so that a modular system gives the musician extraordinary flexibility and individuality."
