The Furman PL-Pro D Series II represents a professional-grade power conditioning and distribution unit designed to deliver clean, stable, and protected AC power to sensitive audio, video, and musical equipment. It operates on the principle that the quality of power directly impacts the performance and longevity of connected gear, addressing common electrical issues such as line noise, voltage spikes, and minor sags that can degrade audio fidelity, introduce visual artifacts, or cause operational glitches. This unit is engineered to provide a robust first line of defense, incorporating multi-stage filtration and protection circuitry to suppress high-frequency electromagnetic and radio-frequency interference (EMI/RFI) that can be induced from lighting systems, dimmers, and other digital devices sharing the same electrical circuit, thereby ensuring a quieter noise floor and more reliable operation for all connected components.

Beyond its core conditioning function, the PL-Pro D Series II is built as a comprehensive power management hub for equipment racks. Its chassis is constructed from heavy-gauge steel, featuring a front panel that includes a precision illuminated voltmeter, allowing users to monitor incoming line voltage at a glance and identify potentially problematic under-voltage or over-voltage conditions. The unit is equipped with a high-current, hospital-grade main power receptacle and a master rocker switch, facilitating convenient control of an entire rack's power. The rear panel offers multiple, generously spaced NEMA 5-15R outlets to accommodate bulky power transformers, with the entire bank of outlets protected by the unit's conditioning and surge suppression circuitry. This design philosophy makes it an organizational centerpiece for both fixed installations and touring racks.

The protection scheme is comprehensive, centered on Furman's proprietary Multi-Stage Protection (MSP) technology, which combines fast-acting metal oxide varistors (MOVs) and a thermal fuse to safely divert damaging voltage transients caused by lightning strikes or major power surges away from connected equipment. This is complemented by both series-mode and shunt-mode noise filtration for broadband interference rejection. The unit's linear filtering technology (LFT) is designed to attenuate interference without limiting current, ensuring ample power is available for high-current-draw amplifiers and processors. With its combination of real-time monitoring, substantial noise filtration, robust surge protection, and reliable switched outlets, the Furman PL-Pro D Series II provides touring professionals, studio engineers, and system integrators with a trusted solution for safeguarding valuable equipment and optimizing system performance through superior power delivery.
