Behringer Surges Multi-Mode Filter for Eurorack

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.
