The Furman PL-8 Series II is an advanced rack-mount power conditioner and surge protector designed to deliver clean, stable AC power and robust protection for sensitive audio, video, and musical instrument equipment. This unit represents a significant evolution from basic power strips by incorporating multi-stage filtration technology to combat electromagnetic and radio-frequency interference (EMI/RFI) that can introduce hum, buzz, and noise into audio signals and cause video artifacts. Its series of toroidal chokes and capacitive filters effectively "scrub" the incoming AC power, isolating connected gear from line-borne noise generated by fluorescent lights, dimmers, and other electronic equipment sharing the same circuit, thereby improving overall system performance and signal clarity.

Beyond advanced noise filtration, the PL-8 Series II provides professional-grade protection against damaging voltage spikes and surges. It utilizes a high-speed Metal Oxide Varistor (MOV) bank with a visual status indicator to show when the protection circuitry is active and functional. The unit also features Furman's exclusive "Series Multi-Stage Protection" (SMP) design, which cascades protection stages to safely clamp and dissipate transient energy, safeguarding valuable equipment from potential damage caused by lightning strikes, utility switching, or internal facility power faults. This comprehensive protection is housed in a compact 1U rack-mountable chassis, featuring eight front-facing, spaced outlets to accommodate bulky power adapters commonly used with modern electronics.

The device includes a highly visible illuminated voltmeter, allowing users to monitor line voltage at a glance and identify potentially problematic under or over-voltage conditions. A master rocker switch with a blue neon indicator provides convenient control of the entire outlet bank. Built with a sturdy all-steel construction, the PL-8 Series II is engineered for the rigors of both touring and fixed installation use. By combining effective noise filtration, robust surge suppression, and convenient monitoring in a single space-saving unit, it offers musicians, sound engineers, and AV professionals a reliable foundation for their power needs, ensuring equipment longevity and optimal system performance.
