PL-PRO DMC OWNER’S MANUAL
lamps are not in use, we recommend turning the dimmer fully counterclockwise, or pushing the knob to the off setting to maximize
the life of the LED’s. Whether the light tubes are fully extended or flush with the front panel, there will be no appreciable heat regard-
less of the dimmer setting due to the efficiency of our full light spectrum LED’s.
All Furman Classic Series Conditioners feature a rear rack BNC socket which will accept any 12 VAC (0.5A) gooseneck lamp assembly
(such as the Furman GN-LED or GN-I). Simply slide the BNC plug over the socket and rotate clockwise until the connector snaps into
the locked position. The rear rack lamp can be powered on or off with the rear light switch which is adjacent to the BNC connector.
ULTRA-LOW RESISTANCE MAGNETIC POWER SWITCH / CIRCUIT BREAKER:
Furman’s Classic Series 20 amp capacity power switch is specifically designed to stand up to the enormous high in-rush current de-
mands of many power amplifiers. Additionally, Furman magnetic circuit breakers are not sensitive to temperature, and will not raise
the AC impedance as do many, less costly thermal breaker. If the 20 amp RMS current capacity of the PL-PRO C is exceeded, the spring
tensioned-switch will immediately switch to the off position. You will need to switch the toggle back to the on position once the prob-
lem is corrected (typically by eliminating one component, or until the RMS current does not exceed 20 amps or 2400 watts).
EXTREME VOLTAGE SHUTDOWN (EVS) INDICATOR:
The Extreme Voltage LED indicator is normally off. It is located within the meter lens assembly directly above the blue voltage / cur-
rent LED’s, though during normal use it will NOT be visible.
The Extreme Voltage indicator monitors a hazard common in the entertainment, remote broadcast, and AV contractor industries: wir-
ing faults. For example: accidental connection to 208VAC where 120VAC is expected, or an open series neutral from a 208 to 240VAC
electrical service. The Furman EVS circuit senses voltages that are so high that operation would be impossible and shuts the power
down before damage can occur.
Upon initially applying power to these units, the Extreme Voltage indicator will light and a red “Extreme Voltage” label will appear at
the top of the meter lens if the input voltage is above the extreme voltage cutoff.
NOTE: If the mains power is above the high cutoff voltage and has caused the EVS circuit to remove power from the PL-PRO DMC’s
outlets, it cannot restore power without the operator manually turning the unit off, then on again. Avoid turning the unit back on
without first checking the source of the problem and changing the AC source (if necessary).
PROTECTION OK INDICATOR:
Although the Furman SMP circuit assures virtually maintenance-free protection from transient voltage spikes and surges, nature has a
way of occasionally creating electrical forces that are beyond the capabilities of ANY surge suppression device to absorb without some
degree of damage (such as a direct lightning hit in an outdoor application). In the rare instance that this occurs, the green “Protection
OK” LED indicator, located at the bottom right of the meter lens assembly, will dim. If this happens, some level of protection from volt-
age surges will remain, but the PL-PRO DMC’s clamping voltage rating will be compromised and the unit must be returned to Furman
for service.
NOTE: Furman’s Classic Series power conditioners do not compensate for high or low AC line voltage. If you frequently move your
rack to different locations, derive power from generators, use very long extension cords, travel internationally, or are in an area prone
to brownouts, you may benefit from the use of one of Furman’s AC Voltage Regulators.
SWITCHABLE DIGITAL VOLTAGE AND TRUE RMS CURRENT METER:
Furman’s laboratory precision AC digital voltmeter continually measures incoming voltages within a typical tolerance of +/-1.5VAC. It
should be noted that the voltage reading is incoming.
Furman’s laboratory precision True RMS digital current meter continually measures the total circuit AC load, within a typical tolerance
of +/- 0.5 amp. Because these meters feature true RMS technology, the current readings are accurate regardless of load conditions
(capacitive, inductive, or resistive). To switch between voltage and current, press the button labeled “Line Voltage/Current”. Hold this
button down for two seconds to dim the brightness of the display.
VOLTAGE RANGE INDICATOR:
This indicator is located in the lower left corner of the digital volt / amp meter lens assembly. When AC voltage is within 5 volts (+/-) of
a nominal 120VAC source, this tri-color indicator will be green (optimal). However, if the voltage is between 110 to 114VAC or be-
tween 126 to 130VAC, the indicator will turn amber (caution - not optimal). If the incoming voltage is in an extreme range (below 110
or above 130), the indicator will turn red. This range is far from optimal, and may be potentially damaging to some equipment.
USB CHARGER:
The Furman PL-PRO C’s USB charger provides an easy way to recharge many popular electronic accessories as well as cellular com-
