Description The Dual Filter Architecture At its core, the RF20 Resonant Filter features two independent, resonant filters. You get a dedicated Low Pass filter and a High Pass filter. These are wired in series to create a powerful, flexible bandpass effect. Consequently, you can carve out specific frequencies with surgical precision or create sweeping, dramatic tonal shifts. Both filters offer a slope of 12dB per octave. In addition, this specific slope provides a smooth yet assertive response that defines the classic analog sound. Therefore, it is perfect for both subtle mixing and aggressive sound design. Tactile Control and Connectivity The interface is intentionally simple and hands-on for maximum creativity. Each filter has dedicated knobs for Frequency and Resonance. Because the resonance can reach self-oscillation, you can generate pure sine waves or chaotic “screams” without any input signal. Furthermore, the unit includes CV (Control Voltage) inputs of Frequency and Resonance for both filter sections. This feature allows you to integrate the RF20 with modular synthesizers or expression pedals. As a result, you can automate your filter sweeps in real-time during a live performance or studio session. Why RF20 Resonant Filter Stands Out Authentic Analog Path: There is no digital modeling here. Instead, the circuitry delivers a warm, organic grit that digital plugins often fail to replicate. Versatility: It works beautifully with synthesizers, drum machines, and guitars. For example, passing a sterile digital synth through the RF20 adds immediate depth and movement. Build Quality: Housed in a rugged metal chassis, it is built to withstand heavy studio use. Moreover, the high-quality components ensure a long lifespan under demanding conditions. In conclusion, the RF20 is a must-have for sound designers. It bridges the gap between traditional effects and modular synthesis. Whether you want subtle warmth or total sonic destruction, this unit delivers. Power: 16v AC True Bypass
