The Behringer 55 Eurorack modules are authentic reproductions of a legendary modular synthesizer, with all of the quirkiness and analog vibe of the original system. A point-to-point reproduction sized for Eurorack, the Behringer 904B Voltage-controlled Highpass Filter delivers the smooth frequency sweeping, gritty character, and squelching high-end that made its predecessor highly coveted by vintage synth collectors. The module consists of two controls ? Filter Control Voltage and Frequency Range. Bearing its historically accurate name, the Filter Control Voltage knob sets the filter’s cutoff point, and the two-position Frequency Range selector lets you choose between a Low (4Hz to 20kHz) band and a High (10Hz to 50kHz) band. Not only does the 904B remove low frequencies, but it also accentuates the high-frequencies for ear-blistering leads that slice through a mix. And, when paired with the Behringer 904B voltage-controlled lowpass filter, it can create brain-bending bandpass effects. The 904B is equipped with signal inputs and outputs and three summed control voltage inputs for blending modulators that affect the filter’s cutoff point. Eurorack enthusiasts at Sweetwater are hyped about the Behringer System 55 modules, including the 904B highpass filter. If you’re ready to step into the world of modular synthesis or add to your existing Eurorack system, you can’t go wrong with these affordable, killer-sounding modules.
