The Furman PS-8R Series II is a professional-grade rack-mount power conditioning unit that combines surge and noise protection with a sequential power-up system. It is designed to protect sensitive audio, video, and lighting equipment from damaging voltage spikes and electromagnetic interference while managing the startup sequence of connected gear. The sequential power-up feature turns on its eight rear-panel AC outlets in a timed order, preventing the large inrush current that occurs when multiple high-draw devices like amplifiers and powered speakers are switched on simultaneously. This helps avoid tripping circuit breakers and reduces stress on connected components.

Beyond sequencing, the unit employs Furman's Multi-Stage Protection (MSP) technology to filter out line noise that can cause hum and degrade signal quality. It features a front-panel illuminated voltmeter for monitoring incoming voltage and an array of status LEDs. Housed in a standard 1U rack-mountable chassis, the PS-8R Series II is a foundational piece of rack infrastructure for touring systems, project studios, and fixed installations. It provides clean, stable power and promotes system longevity by ensuring a safe and controlled startup process.
