Paragraphs

The Vongon Paragraphs is an analog four-pole resonant low pass filter pedal designed with a focus on simplicity and flexibility. Its technical specifications include:

- Dimensions: 5.7 x 4.7 x 1.5 inches
- Power Specs: 100mA @ 9V DC center negative 2.1mm PSU required (not included)
- Input impedance: 1MΩ
- Output impedance: <1kΩ
- True bypass
- Power supply: 9 to 9.6 VDC
- Current draw: 100mA max

The heart of the filter circuit is the AS3320 analog chip, which allows the cutoff to span the full audio spectrum and resonance to start self-oscillating at about seventy percent. The envelope generator offers modulations in a wide range of frequencies, from 0.05 Hz for slowly evolving 20-second long cycles to 300 Hz for a wave shaping effect. The pedal accepts instrument and line level signals, with dedicated controls for input (drive) and output level, and a multi-color LED provides a visual representation of the signal level.

Inputs for Control Voltage (CV) and MIDI are available to remotely trigger the envelope generator, enabling synchronization with external systems like MIDI sequencers, Euroracks, and digital audio workstations.

The pedal is designed to operate using a typical center negative, regulated 9-9.6 VDC power supply and is protected against reversed polarity and overvoltage conditions. It does not have a battery connection inside the pedal.
