Introducing the SoundForce Dual Filter Module, a 12HP Eurorack module that brings classic filter design to your modular setup. Based on one of the most iconic OTA circuits ever created, borrowed from a classic synthesizer, this module utilizes a two-stage cascaded OTA design expanded with improved resonance control, complete with a resonance CV input. With its two-channel design, you can choose each channel’s filter type, allowing you to toggle between 12dB/oct (low-pass) and 6dB/oct (high-pass) settings.
Classic filter design with expanded resonance
The SoundForce Dual Filter Module bases its design around one of the most iconic semi-modular synths ever created, utilizing a two-pole cascaded OTA design that expands on the original design with extended resonance control. With the resonance CV input, you have advanced modulation options, and with the trimmers located on the rear of the module, you can fine-tune your resonance control with maximum precision. The factory value of the resonance is marked on the PCB so you can experiment to your heart’s content.
Designed for efficiency
With its streamlined and intuitive layout, the Dual Filter Module is perfect for beginners and advanced modular users alike. The module is comprised of 3 x OTA ICs and 4 x Op-Amp ICs, providing maximum efficiency and ensuring a long lifespan. Each filter has two audio inputs and two CV inputs for cutoff and resonance, making it ideal for sound design, allowing you to shape and sculpt your sound with maximum precision.
Toggle filter modes with ease
The Dual Filter Module features three jumpers on the back of the PCB, allowing you to toggle between low-pass and high-pass modes with ease. These jumpers are clearly labeled, making it easy to switch between settings.
