INTRODUCTION
Thank you for purchasing a Furman Classic Series power conditioner, and congratulations on your choice. Classic Series power
conditioners feature Furman’s revolutionary Series Multi-Stage Protection (
SMP
) circuit, Extreme Voltage Shutdown (
EVS
), and our
exclusive Linear Filtering Technology (
LiFT
). Together, these technologies comprise precisely what our customers have come to expect
from Furman - uncompromised AC protection and purification. Our Classic Series has been precisely engineered to exceed the critical
demands of audio/video professionals, contractors, broadcasters, and musicians alike.
SMP (SERIES MULTI-STAGE PROTECTION)
Furman’s SMP surge suppression virtually eliminates service calls and costly “down time”. Traditional surge suppression circuits sacri-
fice themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your system and repair of your surge
suppressor. Not so with Furman’s SMP. Damaging transient voltages are safely absorbed, clamped, and dissipated. Your connected
equipment is protected, while your Furman protects itself!
Unique to Furman’s SMP is its unparalleled clamping voltage, defined as the amount of voltage that is allowed to pass through to your
equipment when the protection device is subjected to a transient surge or spike. While other designs offer clamping voltages that are
well above 600 Vpk, Furman’s SMP clamps at 376 Vpk, (266 VAC RMS) even when tested with multiple 6000 Vpk - 3000 amp surges!
This unprecedented level of protection is only available with Furman’s SMP technology.
EVS (EXTREME VOLTAGE SHUTDOWN)
Furman’s trusted over-voltage (EVS) circuitry protects against prolonged overvoltage conditions, such as accidental connections to
330+ VAC, or an intermittent neutral. It does so by monitoring the incoming voltage and, when an unsafe condition is detected,
triggering a relay which shuts off the incoming power until the overvoltage condition is corrected and the power switch is reset.
LIFT (LINEAR FILTERING TECHNOLOGY)
Unfortunately, traditional AC power conditioners have been designed for unrealistic laboratory conditions. Prior technologies, wheth-
er multiple-pole or conventional series-mode filters, 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 reboot digital presets, or destruction of sensitive digital
converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furman’s LiFT takes
a different approach, ensuring optimal performance through linear AC noise filtering with no ground contamination.
PL-PLUS C E ADDITIONAL FEATURES
The PL-PLUS C E features
Smooth Track
LED rack lights which produce virtually no heat and provide an extremely long lifespan. A dim-
mer control for the rack lights allows the user to adjust the level of illumination (by rotating clockwise/counterclockwise) or switch the
lamps on and off (by pushing the knob in). A rear mounted BNC jack accepts any standard (12VAC 0.5 amp) gooseneck lamp for rear
rack illumination.
Additionally, the PL-PLUS C E offers a tri-color multi-segment LED AC voltage meter that displays incoming voltage in 2-volt steps. The
voltmeter’s accuracy is ±2.0 volts. This informs the user whether the voltage is in or out of a safe range, even from a distance too grea
to accurately read the displayed voltage.
