The Behringer SURGES multi-mode filter brings liquid, musical tone coloration to your Eurorack setup. Based on the iconic Mutable Instruments Ripples design, the SURGES offers high-pass, band-pass, and low-pass filtering with selectable 2-pole and 4-pole slopes for band-pass and low-pass outputs. Whether you're shaping dynamic basslines or ethereal pads, the SURGES filter delivers rich, analog tone with precision and flexibility.

Flexible Filtering for Any Patch

With its wide frequency range of 18Hz–18kHz, the SURGES filter is perfect for a variety of sonic applications. The high-pass, band-pass, and low-pass outputs can be configured to add subtle nuances or dramatic shifts to your sound. The slope selector allows you to switch between 2-pole and 4-pole filtering, offering versatile tonal options to suit your creative needs.

Inputs and Modulation Options

SURGES provides two audio inputs, with input 1 featuring a dedicated gain knob that can drive signals into saturation for a warm, overdriven character. Modulate the filter's resonance and cutoff frequencies with external CV inputs, or control the low-pass output level using voltage-controlled gain. The 1V/octave input ensures precise tracking, making the SURGES ideal for melodic patches and advanced modular setups.

Eurorack Ready

The SURGES module is designed to integrate seamlessly into any Eurorack system. At just 8 HP and with power requirements of 35 mA on +12V and -12V, it's compact yet powerful. Whether you're building a portable rig or expanding an existing setup, the SURGES filter fits effortlessly, giving your patches a new dimension of analog warmth and flexibility.

Legendary Analog Sound

Built with 2164 and 13700 semiconductors, the SURGES delivers a "liquid" tone reminiscent of classic SH/Jupiter filters. Its loudness compensation ensures consistent output even at higher resonance settings, maintaining clarity and fullness in your sound. With purely analog circuitry, the SURGES filter is a vital tool for any modular enthusiast seeking rich, musical tone and versatile modulation capabilities.
