INPUT - Route the incoming signal into the filter bank
(1)
via the dual parallel INPUT jacks by using cables
with 3.5 mm TS connectors.
LOW PASS - This knob controls the level of the
(2)
fixed-frequency low pass filter. The low pass filter will
interact with the lower-frequency bandpass filters.
BANDPASS FILTERS - These 12 knobs control
(3)
the output level of the fixed-frequency, high-Q bandpass
filters. The level controls can reduce the level of frequencies
centered around the marked frequency. All 14 filters,
including the low and high pass filters, are in parallel
and will interact with each other to allow control
of musical timbre and resonance.
HIGH PASS - This knob controls the level of the
(4)
fixed-frequency high pass filter. The high pass filter
will interact with the higher-frequency bandpass filters.
OUTPUT - Route the filtered signal back out of the module
(5)
via the dual OUTPUT jacks by using cables with 3.5 mm
TS connectors.

Power Connection
The 914 FIXED FILTER BANK 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 off
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 fixed 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 final position has been established,
tighten the screws down.
