Spectrum

The Spectrum represents 15 years of Source Audio filter expertise in one pedal. 25 filter types include low-pass, band pass, multi-pole, and phaser effects, each with 11 envelope follower options including ADSR triggering.

Dual parallel filters run simultaneously with independent envelope response, Frequency, Depth, Direction, and Q controls. Two octave voices add one/two octaves down or one octave up with lightning-fast tracking. Vintage presets include Mu-Tron and Meatball-inspired sounds.

Four knobs access eight parameters via an ALT button: Input Level, Depth, Frequency, Speed plus Sensitivity, Mix, Resonance, and Volume. Six presets onboard, 128 via MIDI. Stereo I/O, selectable bypass, 165mA at 9V.
