CLASSIC SERIES OWNER’S MANUAL
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 that 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 onditions, these designs can actually add more han 10 dB of noise to the incoming AC line! Worse still, lost digital data, the need to reboot digital presets, or the 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. 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 ear 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 to 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 the voltage is in or out of a safe range, even from a distance too great to accurately read the displayed voltage.
To obtain the best results from your Furman Classic Series power conditioner, please read this manual carefully before using.
To reduce the risk of electrical shock, do not expose this equipment to rain or moisture. Dangerous high voltages are present inside the enclosure. Do not remove the cover. Refer servicing to qualified personnel only. The lightning flash with an arrowhead symbol is intended to alert the user to the presence of uninsulated dangerous voltage within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
IMPORTANT SAFETY INSTRUCTIONS
(Please read prior to installation)
RETRACTABLE SMOOTH TRACK RACK LIGHTS, REAR PANEL LAMP AND DIMMER CONTROL: The Furman Classic Series power conditioners utilize a dimmer control for the two retractable Smooth Track light tubes. The dimmer knob controls the brightness of both front panel lamps. Turn it clockwise to increase brightness; turn it counterclockwise to decrease brightness. The knob is also a momentary power switch for the lamps: push it in to turn the lamps on or off. When the 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 leds. Whether the light tubes are fully extended or flush with the front panel, there will be no appreciable heat regardless of the dimmer setting due to the efficiency of our full light spectrum LEDs.
All Furman Classic Series Conditioners feature a rear rack BNC socket that 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.
ON/OFF ROCKER SWITCH:
Furman’s Classic Series 15 amp capacity power switch is specifically designed to stand up to the enormous high inrush current demands of many power amplifiers. When the top portion of the switch is pressed flush with the panel, power is present.
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/current LEDs, 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: wiring 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 athe 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-PLUS DMCoutlets, 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 voltage surges will remain, but the PL-PLUS 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 between 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.
1.) Symptom: No power to the AC outlets.
Possible Cause: The circuit breaker (located on the rear panel – adjacent to the AC inlet cord) has tripped due to excessive load.
Action Needed: Unplug one piece of equipment from the Furman conditioner and push the round reset tab into the circuit breaker bezel.
2.) Symptom: No power to the AC outlets, the “Protection OK” indicator is not lit.
Possible Cause: Either the AC outlet to which your Furman conditioner is connected has no AC voltage present, or the protection circuitry in your unit has been compromised.
Action Needed: Plug the Furman conditioner into an AC receptacle where a nominal 120 VAC is present. If the problem persists, contact Furman for service.
3.) Symptom: Extreme Voltage (EVS) indicator lit.
Possible Cause: Input voltage is above 140V causing power to the unit’s outlets to be shut down. Additionally, if the voltage is below 85V – 90V at turn on, the unit will not allow AC voltage to reach the outlets.
Action Needed: Correct the line voltage, then turn the Furman conditioner on. If the voltage present is below 114 VAC or above 126 VAC, consider installing a Furman voltage regulator.
