The PST-8 all feature Furman’s SMP circuit which incorporates Linear Filtering Technology (LiFT) and a high current TVZ-MOV to insure that any electronic device (including televisions, projectors, CD-DVD players, or computers) is fed clean, filtered AC power. 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. Conventional AC conditioners employing older technologies leak voltage to circuit ground which can, in fact, aid in damaging sensitive digital circuits such as computer processors. Furman’s new technology, however, never directs voltage to the circuit ground further ensuring the safety of your equipment. Additionally, today’s power grid commonly experiences numerous electrical surges and spikes on a daily basis. At best, these irregularities can degrade your equipment’s performance, and, at worst, can severely damage your entire system. Furman’s SMP circuit offers the highest degree of protection available without sacrificing itself or any of its components.
