Description
Stereo Envelope Filter, Wah-Wah, and Parametric
The Mu-Tron SUPER-FREQ is a dual state variable filter with multiple routing and actuating options. Either filter can be run as an ENVELOPE FILTER, WAH-WAH pedal, or a PARAMETRIC EQ with resonance control. It can be used in STEREO, MONO IN -DUAL OUT , or MONO-SERIES to allow for limitless applications.
A state variable filter is a type of active filter in electronic circuits which can produce simultaneous lowpass, highpass, and bandpass outputs from a single input. State variable filters are frequently used for modifying frequency response in audio signal processing. At low Q settings they are often used in parametric equalizer circuits, and at high or variable Q settings to create resonant filter modules in analog synthesizers. For manual control of frequency, dual potentiometers are usually employed as in the Tychobrahe Parapedal, Alembic SF-2, and Anderton Super Tone Control. The SUPER-FREQ utilizes optical circuits to servo both filters simultaneously. Both the Mu-Tron III and the Mu-Tron Vol-Wah are examples of optically controlled state variable filters. The Mu-Tron III translates the musician’s playing dynamics into current which then drives an LED. The Mu-Tron Vol-Wah uses a potentiometer in the foot pedal to sweep current to the LED. The LED in either design then servos multiple photo-resistors to vary the resistance of the state variable filter.
Features and Improvements:
- Modular optical design which allows for consistency across units.
- Optical servo of both filters simultaneously is built into the pedal.
- Original bi-polar internal voltage insures high headroom and low noise
- Independent effect block can be combined in series or parallel operation
- Pedal control assignable to rate to achieve “Wah-Wah” sweep with foot
- Envelope control of either filter
- LED (light emitting diode) indicators to show operating status of effects.
- Routes signal from right to left to be more pedal board friendly.
- Operates on standard 9v (negative center tip, 100mA power port)
- Multiple routing capabilities
Controls:
- Frequency controls the range of frequency manipulation.
- Peak controls can be used as resonance or damper control.
- Low pass, Band pass, and High pass modes.
- Up and Down drive for either Envelope can be fined tuned internally.
- Direct gain to allow for dry signal to be blended with filtered signal.
