The Maxon AF9 Auto Filter takes the most desirable auto-wah and swept filter effects and offers them up in a compact, user-friendly package. Opto-coupler circuitry produces the shimmering, watery filtering of legendary vintage units. Threshold and Peak sliders control the degree of effect; while Range and Drive switches determine range and direction of the filter sweep. Three selectable filter types (Low Pass, Band Pass, and Hi Pass) and a frequency range of 100 Hz – 4 kHz allow the AF9 to function with virtually any instrument or input signal.

Originally introduced as a key component of analog synthesizers, envelope controlled filters came into prominence in the early 1970s with the release of the legendary Mutron III. Envelope filters are wah-wah type sliding filters that are triggered by an input voltage. Unlike standard wah pedals whose center frequency is controlled by moving a treadle, an envelope filter\'s center frequency is controlled by playing dynamics, allowing for an almost unlimited variety of effects based on expressive nuances in a player\'s performance.

The AF-9 Auto Filter represents the state-of-the art in analog filtering. Like the original Mutron III, the AF-9 uses a CdS Photocoupler (HTV #P873) rather than a VCA at the heart of its circuit. The unique sound of Photocoupler circuitry provides a liquid, shimmering, vowel-like filtering that cannot be produced with other components, giving the AF-9 superior sound quality with lower noise levels than the competition.

The AF-9\'s Threshold control determines when the effect will trigger, while the Peak control boosts the center frequency for more dramatic filtering (like a Resonance control on a synthesizer). Selectable Range control (Hi/Low) determines the overall tone of the AF-9, while the Drive (Up/Down) control determines the direction of the filter sweep. Three selectable Filter types (Hi Pass, Band Pass, and Low Pass) and a frequency range of 100 Hz Ð 4 KHz allow the AF-9 to function with virtually any instrument or input signal.

From simple wah-wah\'s to outer-space noises, the AF-9 provides the most desirable swept filter effects in a compact, user-friendly package.
