VIDEOS
DOWN 1: Controls the volume level of the 1-octave-down signal. Both this and the 2 Down control have been tuned to provide the best possible tracking across all positions on the fretboard.
FILTER 1: This control governs the cutoff point for a second-order low-pass filter on the 1 Down knob. At minimum, the cutoff point is ~7KHz, retaining all the harmonic richness and video game-esque qualities. At maximum, the cutoff point is ~280Hz, giving you a clean octave down with bubbling harmonics lying underneath.
DRY: This knob controls the volume of the dry signal. It is not your true clean guitar signal, but rather a boosted version of it, allowing it to mix better with the octaves. There’s plenty of volume on tap and it sounds great just by itself.

DOWN 2: Just like Down 1, Down 2 controls the level of the 2-octave-down signal.
FILTER 2: This control governs the cutoff point for a deeper second-order low-pass filter on the Down 2 knob. At minimum, the cutoff point is ~7KHz, just like “1 Filter.” However, at maximum, the cutoff point is ~140Hz to really let the “oomph” shine through at higher settings.
You can power your Perseus DIO with any 9VDC quality power supply designed for use with effects pedals.
