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
sacrifice 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 330 Vpk, Furman's SMP clamps at 188 Vpk, (133 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 208
or 240 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,
whether 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 DMC ADDITIONAL FEATURES
The PL-PLUS DMC features Smooth Track LED rack lights which produce virtually no heat and provide an extremely long lifespan. A
dimmer 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.
The PL-PLUS DMC is equipped with a front panel convenience AC outlet and eight rear panel outlets in two isolated banks. The outlets
in Bank A are spaced to accommodate transformer plugs (wall warts). Since the banks are isolated from each other, it is recommended
to connect analog equipment into Bank A and digital equipment into Bank B (or vice versa). The PL-PLUS DMC's 15A (1800 watt)
capacity is supplied from a robust 14 AWG, 10 foot AC cord.
Additionally, the PL-PLUS DMC offers a switchable laboratory precision digital meter that displays incoming voltage in 1-volt steps or
true RMS current in 0.1 amp steps. The voltmeter's accuracy is ±1.5 volts and features a tri-color voltage range indicator. This informs
the user whether voltage is in or out of a safe range, even from a distance too great to accurately read the displayed voltage.
