Quick Start Guide
110 VCO/VCF/VCA
Legendary Analog VCO/VCF/VCA
Module for Eurorack
Controls
(1) PW MOD – Accepts a voltage from another module
to control the pulse width. When a jack is inserted the
MOD MANUAL control acts as a MOD input level control.
(2) VCO OUT – Send the VCO signal to another source via
3.5 mm TS cable.
(3) WAVEFORM – Select triangle, sawtooth or pulse
waveforms for the VCO.
(4) MOD MANUAL – Sets the ratio between the upper and
lower portions of the pulse wave.
(5) RES – Boosts the resonance frequencies selected with the
CUTOFF FREQ slider, potentially causing VCF oscillation.
(6) CUTOFF FREQ – Adjusts the cuto frequency of the
low-pass lter.
(7) RANGE – Sets the pitch range of the VCO in octave steps.
(8) PITCH – Fine tunes the pitch.
(9) VCF/VCA SIG IN – Connect incoming signals via 3.5 mm
TS cables.
(10) SIG LEVEL – Adjust the level of the signals connected to
the inputs.
(11) VCA OUT – Sends the VCA signal via 3.5 mm TS cable with
either high or low signal levels.
(12) INITIAL GAIN – Adjusts the initial gain level when there is
no control voltage present. The adjacent LEDs will light to
indicate signal (green) and overload (red).
(13) MOD LEVEL – Adjusts the level of the signal connected to
the associated MOD IN jack.
(14) MOD IN – Accepts voltages that control or modulate the
VCO, VCF or VCA.
Power Connection
The module comes with the required power cable for connecting
to a standard Eurorack power supply system. Follow these
steps to connect power to the module. It is easier to make
these connections before the module has been mounted into
a rack case.
1. Turn the power supply or rack case power o and
disconnect the power cable.
2. Insert the 16-pin connector on the power cable into the
socket on the power supply or rack case. The connector has
a tab that will align with the gap in the socket, so it cannot
be inserted incorrectly. If the power supply does not have
a keyed socket, be sure to orient pin 1 (-12 V) with the red
stripe on the cable.
3. Insert the 10-pin connector into the socket on the back of
the module. The connector has a tab that will align with the
socket for correct orientation.
4. After both ends of the power cable have been securely
attached, you may mount the module in a case and turn on
the power supply.
