The SPH-2 is a 14-stage stereo image phaser. It consist of two identical voltage controlled all-pass filters with seven notches stretched over the whole audio range which ensures constant phasing effect. the all pass filters are combined with original audio signals resulting in an almost constant gain and phase shift of 2400 degrees across the entire audio range.
Additionally, the phasing effect remain almost constant even in saturation mode. Phasing (spectrum) is controlled by modulating the internal low frequency oscillator (mod rate, mod level) and by external signals (spectrum cv, and separate spectrum left, right).
The low frequency oscillator's rate can be modulated by external signals (Rate CV knobs and input). There are three audio inputs: left, right, and a combined input for processing by both phasers. The audio outputs are provided by output socket labelled Audio, Left, Mix (mixed left and right phaser), and Right. Outputs are revealed by white surrounds.
The Feedback knob controls the amount of multi resonance for both phasers (up to self-oscillation). The Spatial/Rotating switch couples the phaser between two different stereo images.
