Figure 5.
The rear panel of the Expander Module
has four slide switches that select the voltage
ranges of the inputs and outputs.
Normally, set all four switches to up position for
compatibility with standard +/-2.5 V control
voltages.
Try the 0..5 volt range when connecting to MIDI-CV
converters and tabletop analog gear (including
Grendel Drone Commander classic and Grendel
RA-9 Grenadier)
If SW.3 is down, the AUX IN gain is + 6dB.
If SW.4 is up, the MAIN OUT level is + 6dB.
It is OK to experiment. All jacks are protected
against short-circuit and overvoltage.
Never apply
more than +/-15 volts to any patch point.
The VCO CV inputs work with signals in the range of 0 to +5 volts only. Voltages outside this range are limited
by internal protection circuitry. That means:
Ÿ
VCO CV inputs work ideally with MIDI-CV converters or CV-Gate keyboards that use the 0-5 volts range.
Ÿ
To connect a bipolar LFO for vibrato or FM effects, its output should to be offset by +2.5 volts with a utility
module (not included). This can be accomplished with a DC-coupled CV mixer and bias voltage source.
