PH-01 Phaser

PHASER

The Yamaha PH-01 Phaser is part of Yamaha’s Professional System Effectors “01” series, intended to function either standalone or integrated into a modular effects rig. It uses an analog phase-shifting circuit and offers two controls: Speed, which governs the rate of the LFO modulation, and Depth, which sets how wide the modulation sweep is. The modulation cycle rate spans roughly 1 to 10 seconds at its extremes. It includes an LED indicator to show when the effect is active. It is designed for low noise operation, even with high output sources. The housing is robust, typically a black die-cast metal enclosure, with top or side connectors to suit modular integration.
