Behringer 110 VCO/VCF/VCA User manual

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.

Installation
The necessary screws are included with the module for mounting
in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of xed holes
spaced 2 HP apart along the length of the case, or a track that
allows individual threaded plates to slide along the length
of the case. The free-moving threaded plates allow precise
positioning of the module, but each plate should be positioned in
the approximate relation to the mounting holes in your module
before attaching the screws.
Hold the module against the Eurorack rails so that each of the
mounting holes are aligned with a threaded rail or threaded
plate. Attach the screws part way to start, which will allow
small adjustments to the positioning while you get them all
aligned. After the nal position has been established, tighten the
screws down.
