Obsidiana

The Obsidiana by Paradox Effects is an octave layering engine with the following technical specifications:

- Power Supply: 9vDc (No battery option)
- Minimum Current Draw: 100mA
- Dimensions: 125(D) x 95(W) x 55(H) (with jacks and knobs)
- Weight: 350g

The pedal features a multi-voice, polyphonic octave machine with two types of filters and a unique feature set. It offers two filter options: 1 pole low pass and 2 pole resonant low pass filter. The Obsidiana is designed to create syncopated rhythms or layers of reflective evolving pitches. It responds well to both chords and single notes, processing broad signal spectrums while maintaining a warm and balanced analog direct signal.

The controls on the Obsidiana include:
- OCTAVE DOWN: Controls the level of octave down.
- OCTAVE UP: Controls the level of octave up.
- DIRECT: Controls the Dry signal output.
- FILTER: Adjusts the filter tone, with 1P moving the filter tone from dark to bright and 2P creating more drastic and spatial changes.
- EXP: Expression pedal TRS input, controlling the "Filtro" parameter.
- LAG: Controls the space between the attack and the voice of the note or the space between the octave ramifications.
- REGEN: Adjusts the feedback of the octaved signals to provide more upper and lower octaves to the overall wet signal.
- RAÍZ: Switches between conventional octaver tracking and "crystalized" octaver with syncopated ramifications.
- VOZ: Switches between Obsidiana voice and Shift voice mode.

The Obsidiana is recommended to be powered by a regulated 9 volt Dc power supply with a minimum current draw of 100mA. It is important to use a power supply with good regulation, isolation, and filtering to avoid unexpected noise or damage to the pedal.
