The Behringer SURGES is a voltage-controlled multi-mode filter for Eurorack, providing high-pass, band-pass, and low-pass outputs. Based on Mutable Instruments Ripples, it offers a "liquid" and musical tone coloration reminiscent of classic SH/Jupiter filters, along with versatile CV inputs and a wide frequency range.

• Voltage controlled multimode filter which provide high-pass, band-pass and low-pass. The slope of the band-pass and low-pass output is switchable (2-pole or 4-pole).
• Based on Mutable Instruments Ripples.
• “Liquid” and musical tone coloration reminiscent of SH/Jupiter filters.
• Loudness compensation with increased resonance.
• Wide frequency range from 18 Hz to 18 kHz.
• Purely analog circuitry based on legendary 2164 and 13700 semiconductors.
• Audio inputs – signals from input 1 and 2 are mixed together with input 1 having a dedicated level knob that can result in an overdriven sound when pushed.
• CV inputs – resonance and cutoff modulation.
• Voltage controlled gain for low-pass output – externally control the level of the LP signal.
• Eurorack specs: 8 HP, 35 mA +12 V, 35 mA -12 V.
