I N T R O D U C T I O N
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.
