Quick Start Guide
914 FIXED FILTER BANK
Legendary Analog Fixed Filter Bank Module for Eurorack
Controls
- INPUT – Route the incoming signal into the filter bank via the dual parallel INPUT jacks by using cables with 3.5 mm TS connectors.
- LOW PASS – This knob controls the level of the fixed-frequency low pass filter. The low pass filter will interact with the lower-frequency bandpass filters.
- BANDPASS FILTERS – These 12 knobs control 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 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 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.
- Turn the power supply or rack case power off and disconnect the power cable.
- 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.
- 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.
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 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 is aligned with a threaded rail or threaded plate. Attach the screws partway 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.
