For over 30 years, Furman has pioneered the development of AC power products for the most demanding audio, video, and broadcast professionals. Furman’s Series Multi-Stage Protection (SMP) delivers the purest AC power and the most comprehensive protection available – going far beyond what is found in traditional surge strips. With Furman’s Power Station Series, everyone can reap the benefits of unrivaled power purification and unequaled surge protection. This dramatically reduces noise, ensuring consistent peak performance from your equipment. Typical AC filters feature antiquated non-linear circuits. Though these multiple-stage filters or power cleaners reduce some noise, they do so unevenly. In fact, they can add noise to your power line due to their filter’s excessive resonant peaking. With Furman’s proprietary Linear Filtering Technology (Lift), AC noise is suppressed evenly, assuring maximum performance from your system. Furman’s SMP circuit offers the highest degree of protection available without sacrificing itself or any of its components. Another feature that is unique to Furman’s SMP circuit is the automatic extreme-voltage shutdown. Extreme voltages are statistically the most common, damaging AC event. The Extreme Voltage Shutdown circuit automatically turns off the unit when it is fed 137 volts or higher protecting itself and connected equipment from the extreme voltage. Only Furman offers this degree of protection! Add Telco and cable /satellite transient voltage suppression, and you have what is, unquestionably, the most comprehensive protection available in a portable AC power conditioner. Advanced Linear Filtering dramatically reduces AC line noise and contamination resulting in improved audio/video clarity.
