SERIES II 20 amp Power ConditionerS

Thank you for purchasing a Furman Series II Power Conditioner, and Congratulations on your choice. The Series II power conditioners feature Furman’s revolutionary Series Multi- Stage Protection Plus (SMP+) circuit, as well as our exclusive Linear Filtering Technology (LiFT). Together, these technologies comprise what is, without question, the world’s most advanced and comprehensive transient voltage surge suppressor / conditioner.

SMP+ (Series Multi-Stage Protection Plus)

Furman’s SMP+ surge suppression virtually eliminates service calls. Traditional surge suppression circuits “sacrifice” themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system, and repair of your surge suppressor. Not so with SMP+. With Furman’s SMP+, damaging transient voltages are safely absorbed, clamped, and dissipated.

Unique to Furman’s SMP+ is its unparalleled clamping voltage. While other designs offer clamping voltages that are well above 330 Vpk, Furman’s SMP+ clamps at 188 Vpk, (133 VAC RMS). This unprecedented level of protection is only available with Furman’s SMP+ technology. Additionally, Furman’s

trusted over-voltage circuitry protects against all too frequent accidental connections to 208 or 240 VAC, by shutting off the incoming power until the over voltage condition is corrected. [For E versions: Furman’s SMP+ clamps at 376 VpK, (266 VAC RMS.)]

LiFT (Linear Filtering Technology)

Unfortunately, traditional AC filter - conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multiple pole filter or conventional series mode, could actually harm audio and video performance more than they help, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs can actually add more than 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to re-boot digital pre-sets, or destroyed digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman’s SMP+ with LiFT takes another approach, ensuring optimal performance through linear filtering and no leakage to ground.
