Quick Start Guide
CP3A-M MIXER
Legendary Analog Mixer/Utility
Module for Eurorack
Controls
(1) CHANNEL INPUTS connect the incoming signals via
cables with 3.5 mm TS connectors.
(2) CHANNEL GAIN knobs adjust the input volume for the
CHANNEL INPUTS.
(3) MULTIPLE connections act as a patchbay so that copies of
the input signals can be routed out to other modules for
further processing.
(4) OUTPUTS connections send out the mixer module’s nal,
summed signal. The OUTPUTS section features two sets of
output jacks with negative and positive polarity.
(5) MASTER GAIN controls the nal volume at the
OUTPUTS jacks.
Power Connection
The CP3A-M MIXER 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.
