Behringer 923 Filters

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. Modular synths were a landmark development in electronic music and today, it’s about to get better. Enter the Behringer 923 FILTERS. 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 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 10Hz to 10KHz 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.
