Behringer System 55 923 Filters Eurorack Module

The Behringer System 55 923 Filters Eurorack Module is an authentic reproduction of the circuitry from the “Modular 35 and 15” series filters used by the world’s most famous pop, rock and jazz musicians. Now you can build your very own, unique synthesizer that can fit in a standard Eurorack case for a very affordable price. Mix and match with specific modules to customize your synth and complement the genre of music you play or go all out and have a room filled from floor to ceiling with modules that’ll fulfill any synth geek’s wildest dreams.

The first System 55, 35 and 15 synth modules came out in the early 70s and tended to be extremely expensive. They were mainly all discrete transistor designs as op-amps at the time were very high cost. The discrete circuitry gave the modules a very distinctive sound and were used by artists like Keith Emerson, Stevie Wonder, Tangerine Dream and so many more, giving us some of the greatest records we’ve ever heard.

Controls

The 923 features separate Low and High Pass filters each with their own dedicated frequency cutoff controls. The Low Pass filter control will roll off all frequencies above the set threshold frequency from 10 Hz to 10 kHz while the High Pass filter control will roll off frequencies below the set frequency. Each filter comes with their own 3.5 mm ins and outs giving you the ability to route incoming signals through the IN jack, through the filter and back out the OUT jack.

Have it Pink or White

For you to shape an endless number of tones, the 923 comes with a white and pink noise generator. Use the parallel jacks for each of the noise sources to send out a white or pink noise signal and start sweeping frequencies to build tension and excitement in your songs, or use them to create some percussive sounds for a real groovy drum beat.

Eurorack Ready

Installing the 923 is simple as it was designed to fit into a standard Eurorack case. Just connect the power cables to the power supply and screw in the module using the included screws. This allows for the 923 to be mixed with other synth modules for a truly unique set up.
