Three Year Limited Warranty
Important Note: To be sure of obtaining full protection under the terms of the Limited Warranty in case your ownership documents are lost, please fill out and return the Warranty Registration Card immediately. Please verify that the serial number shown on the Warranty Card matches the serial number on your unit.
The Furman PL-PRO is warranted against failures due to defective parts or faulty workmanship for a period of three years after delivery to the original owner. During this period, Furman will make any necessary repairs without charge for parts or labor. Shipping charges to the factory or repair station must be prepaid by the owner; return shipping charges (via UPS Ground) will be paid by Furman. This warranty applies only to the original owner and is not transferable. Also, it does not apply to repairs done other than by the Furman factory or Authorized Repair Stations. This warranty shall be cancellable by Furman at its sole discretion if the PL-PRO unit has been subjected to physical abuse, has been operated without a proper safety ground, or has been modified in any way without written authorization from Furman. Furmans liability under this warranty is limited to repair or replacement of the defective unit. Furman will not be responsible for incidental or consequential damages resulting from the use or misuse of its products. Some states do not allow the exclusion of incidental or consequential damages, so the above limitations may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. Warranty claims should be accompanied by a copy of the original purchase invoice showing the purchase date (if a Warranty Registration Card was mailed in at the time of purchase, this is not necessary). Before returning any equipment for repair, please read the important information on service below.

Safety Information

To obtain best results from your Furman PL-PRO, please be sure to read this manual carefully before using it. WARNING: 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 covers. Other than the light bulbs, there are no user serviceable parts inside. Refer servicing to qualified personnel only. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
Important Safety Instructions Please read prior to installation
1. Please read and observe all of the safety and operating instructions before the PL-PRO is operated. Retain these instructions for future reference. 2. The PL-PRO should not be used near water for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc. 3. The PL-PRO should be situated so that its location and position do not interfere with its proper ventilation. For example, the PL-PRO must not be placed on a rug, bed, sofa, or similar surface which impedes airflow across the chassis. 4. Do not place the PL-PRO near heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. 5. The PL-PRO should only be connected to a 120 VAC, 60 Hz, 20 amp grounded electrical outlet. Outlets wired for 20 amps may be identified by the T-shaped socket opening that accepts the perpendicular blades of the PL-PROs power plug. If you dont have a 20 amp outlet available, have one installed by a qualified electrician. Do not defeat the ground or polarization of the power plug.

6. Route the power cord and other cables so that they are not likely to be walked on, tripped over, or stressed. Pay particular attention to condition of cords and
cables at plugs, and the point where they exit from the PL-PRO. To prevent risk of fire or injury, damaged cords and cables should be replaced immediately. 7. Clean the PL-PRO with a damp cloth only. Do not use solvents or abrasive cleaners. Never pour any liquid on or into the PL-PRO. 8. When left unused for a long period of time, the power cord of the PL-PRO should be unplugged from the outlet. 9. The PL-PRO should be serviced by qualified service personnel when: a. The power supply cord or the plug has been frayed, kinked, or cut. b. Objects have fallen or liquid has spilled into the unit. c. The PL-PRO has been exposed to rain or other moisture. d. The PL-PRO does not appear to operate normally or exhibits a marked change in performance. e. The PL-PRO has been dropped, or the enclosure damaged. 10. The PL-PRO requires that a safety ground be present for proper operation. Any attempt to operate the PL-PRO without a safety ground is considered improper operation and could invalidate the warranty. 11. Light bulbs are the only user-serviceable parts in the PL-PRO. Instructions for replacing them are on pages 6-7. The light tubes and end caps become quite warm to the touch in normal operation. To avoid burning your fingers, allow the cap to cool completely before unscrewing it. If you find that the heat from the tubes is excessive, try reducing the setting of the dimmer knob. 12. Do not attempt to service the PL-PRO beyond what is described in this manual. All other servicing should be referred to qualified service personnel.

NOTE: The Voltmeter and status LEDs stay on even when the power switch is off. This feature allows you to check voltage before powering up your equipment. These LEDs are designed for continuous, ongoing use. They consume little power, just a few cents worth a month, like a clock.
UNSWITCHED OUTLET: This outlet provides conditioned power at all times when the PL-PRO is plugged in and operating under normal conditions. CIRCUIT BREAKER/ON-OFF SWITCH: This appears to be an ordinary toggle switch, but in fact is a precision magnetic circuit breaker. Because its operation is magnetic, not thermal, it is much more accurate in its tripping current, yet it will not be tripped falsely by the transient high inrush currents often encountered when turning on large reactive loads like power amps. Its trip point is unaffected by ambient temperature. The breaker/switch controls power to the eight switched rear panel outlets, but does not affect the voltmeter, the ammeter, or the status LEDs. If it trips, reduce the load on the PL-PRO and push it back to the ON position. (Note: The PL-PRO-Es circuit breaker is not magnetic.)

Introduction

Thank you for your purchase of a Furman PL-PRO or PL-PRO-E Power Conditioner and Light Module, and congratulations on your choice. (For simplicity, in this manual the designation PL-PRO refers to either the PL-PRO or the PL-PRO-E unless a specific distinction is made. A summary of the differences between the two models appears at the bottom of this page.) The PL-PRO is one of Furmans top-of-the-line PRO Series power conditioners. It is designed to provide maximum protection from the types of hazards faced by delicate analog and digital pro audio and video equipment. Your PL-PRO provides the most complete and comprehensive protection from power line-related transient voltages, noise and wiring faults available. It combines a high voltage surge and transient suppressor with an RFI/EMI interference filter. The fast-acting suppression circuit responds in less than a nanosecond, clamping transient voltages to safe levels. The filter works to prevent noise from fluorescent lights, certain dimmers, radio transmitters, and similar sources of electronic pollution from contaminating the AC line and from there, leaking into sensitive audio, video, or computer circuits. What sets the Furman PRO Series apart from other conditioners is the quantity, quality, and configuration of its suppression devices. These include MOVs, gas discharge tubes, fast-blow fuses, and high voltage inductors and capacitors. This unique combination can safely absorb and dissipate large spikes from nearby lightning strikes and other sources (up to 11,000 amps across any wiring mode hot-neutral, hot-ground, or neutral-ground), as well as highly attenuate audible high frequency noise. Precise high-inrush magnetic circuit breakers avoid the false tripping often encountered with large reactive loads like power amps. The PL-PRO front panel provides a three-color, 20-LED line voltage meter, and three status LEDs to indicate abnormal power conditions. Under extreme conditions, the PL-PRO will even keep itself from turning on, or shut down if the voltage is below 80 volts or above 140 volts (below 160 V or above 280 V for the PL-PRO-E). There is a dimmer control for the two front panel light tubes, which also include a feature exclusive to Furman that automatically turns both lights off when either light tube is pushed back in. The front panel also provides an unswitched outlet (clean, filtered power is provided at the unswitched outlet, too) and a 20 amp (16 amp for PL-PRO-E) magnetic circuit breaker rated for use as an ON/OFF switch. The rear has eight switched AC outlets to power up all your equipment. These outlets are spaced widely enough to accommodate up to four plug-mounted power supplies (wall warts). The heavy duty 12 AWG power cord is 10 feet (2.4 m) in length for extra reach and durability on stages and other high-traffic areas.

Effects of Lightning

Lightning is a natural phenomenon of overwhelming force that represents the most difficult circumstance faced by a power protection product. The degree of protection a PL-PRO can offer depends on the intensity of the strike. If lightning strikes a distant power line and causes a relatively small disturbance to reach your location, the spike suppressors in the PL-PRO will absorb the excess voltage invisibly and harmlessly. However, if lightning strikes the actual building where the PL-PRO is installed (or somewhere very nearby), some damage may be unavoidable due to the extremely high voltage and current present. If this does occur, most likely damage will be limited to the PL-PRO itself and will affect only certain spike suppression components (called varistors or MOVs.) In this suicide mode, the PL-PRO may sustain minor damage but generally will protect all equipment plugged into it from much more serious and costly damage as long as that equipment is properly grounded. Proper grounding requires the use of three-prong AC cords, and that the buildings outlets are actually grounded to earth as specified by the National Electrical Code. Any PL-PRO known to have taken a direct lightning hit should be checked by a qualified technician or the Furman factory to determine whether the MOVs need replacement. (If the PROTECTION OK indicator is not lit, there is definitely some damage. Some spike suppression capability may still be available by MOV Bank #2, but there is no guarantee of this.) For optimum protection, you should not rely exclusively on the PL-PRO to protect against a direct lightning hit. The first line of defense against lightning should be a lightning arrestor installed on your buildings electrical service entrance. If your building does not have one, contact your local power company or a contractor to have one installed.
PL-PRO Compared to PL-PRO-E
The PL-PRO is intended for use with 120 VAC power and is rated at 20 amps; the PL-PRO-E is for 230 VAC power and rated at 16 amps. Outlets on the PL-PRO-E are IEC-320 types. The GROUND OK feature is not available on the PL-PRO-E. Other differences concern the reading of the voltmeter and ammeter and other specifications, which are described on page 8 and on the rear cover.

DIMMER: This knob controls the brightness of both light fixtures. Turn it clockwise to increase brightness; turn it counterclockwise to decrease brightness. PROTECTION OK: This LED is normally on when the power to the PL-PROs outlets is switched on. It monitors the integrity of the protection devices and reports if the protection is compromised. If an extremely large spike is encountered that exceeds the PL-PROs capacity, the main group of input protectors will blow an internal fuse, causing the indicator to go out. If this LED is not lit when the power switch is on, full protection is not functioning. Spike protection may still exist, but will have a reduced capacity to absorb current. If this LED is not lit, please contact the Furman Service Department. GROUND OK: This LED is normally on when the power to the PL-PROs outlets is switched on. It monitors the integrity of the grounding, and reports if the grounding is compromised. It lights if a reasonably good safety ground exists. If this LED is not lit when the power is on, the PL-PRO is not properly grounded. Unplug the PL-PRO and correct the ground. (Not available on PL-PRO-E.) EXTREME VOLTAGE SHUTDOWN: This LED is normally off. It monitors a hazard unfortunately common in the entertainment industry: wiring faultsfor example, accidental connection to 220V where 120V is expected. The PL-PRO senses voltages that are so high or low that operation would be impossible and shuts the power down before damage can occur. For the PL-PRO, the cutoff voltages are under 80V or over 140V; for the PL-PRO-E, under 160V or over 280V. Upon initially applying power to the PL-PRO, this LED will be lit if the input voltage is below the low cutoff or above the high cutoff, and power will not be applied to the PL-PROs outlets. If the unit has been operating with an acceptable input voltage and then that voltage goes out of the acceptable range, the PL-PRO will shut off power to the outlet and this LED will begin flashing.
or almost anywhere household light bulbs are sold. Bulbs are easily replaced without removing the unit from the rack. Heres how: First, pull the light tube(s) all the way out. Unscrew the cap on the end of each tube to get access to the bulb. (Be careful not to push the tubes in after you have removed the caps.) To unscrew the bulb, place your index finger across the hole on the underside of the tube and in contact with the bulb. Use the ball of your finger to rotate the bulb out of its socket. Then remove the bulb from the front of the light tube. Put a new bulb in the tube, rotate it with your finger from the hole in the bottom of the tube and replace the light tube cap(s).
NOTE: The caps and light tubes become quite warm to the touch in normal operation. To avoid burning your fingers, allow the cap to cool completely before unscrewing it. If you find that the heat from the tubes is excessive, try reducing the setting of the dimmer knob. As an alternative, you may substitute four-watt bulbs or even colored Christmas tree bulbs.

LED VOLTMETER: This three-color, 20-LED bargraph is an accurate, self-checking AC voltmeter that continually measures normal voltages. The meter reads from 90 to 128 volts in 2 volt steps (PL-PRO-E: 180 to 256 volts, in 4 volt steps). The normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively (see chart on page 8). The voltmeter provides three special flashing patterns to indicate abnormal power conditions: (1) If only the single leftmost (beneath the 90V mark) LED flashes, the input voltage is marginally low. Power to the PL-PRO outlets will remain on unless the incoming voltage falls below the Extreme Voltage Shutdown low cutoff. (2) If all of the LEDs on the voltmeter flash, the input voltage is marginally high. Power to the PL-PROs outlets will remain on unless the incoming voltage rises above the Extreme Voltage Shutdown high cutoff. (3) If none of the LEDs on the voltmeter are lit, and the Extreme Voltage LED indicator is flashing continuously, then the PL-PRO has shut down power to its switched outlets because the input voltage is in a range considered extreme. The PL-PROs voltmeter has a basic accuracy of plus or minus two volts, and extreme cold or heat may cause an additional one volt of error (four volts and two volts for PL-PRO-E). Please note that the voltage reading is advisory only. The PL-PRO does not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benefit from the use of one of Furmans AC Line Voltage Regulators.
NOTE: If the mains power is below the low cutoff voltage and has caused the PL-PRO to remove power from its outlets, the PL-PRO will not restore power to the outlets until the mains voltage rises to more than 10V above the cutoff. Similarly, if the mains power is above the high cutoff and has caused a shutdown, the PL-PRO will not restore power to the outlets until the mains voltage falls more than 10 volts below the cutoff. The reason for this is to prevent the power oscillating on and off in marginal conditions.
LIGHT TUBES: The PL-PRO has the familiar slide-out rack lights pioneered by Furman. A new feature exclusive to the PL-PRO automatically turns the lights off when either light tube is pushed in. The PL-PROs lamps come supplied with seven-watt night light bulbs. Replacements are available at most hardware stores

SERIES II 16 AMP POWER CONDITIONERS INTRODUCTION
Thank you for purchasing a Furman Series II Power Conditioner, and congratulations on choosing the best protection for your electronics. Series II Power Conditioners feature Furmans revolutionary SMP+ circuitry, as well as our exclusive Linear Filtering Technology (LiFT). Together, SMP+ and LiFT comprise what is, without question, the worlds most advanced and comprehensive transient voltage surge suppressor / conditioner. to 380 VAC, by shutting off the incoming power until the over-voltage condition is corrected.
LiFT (Linear Filtering Technology)
Unfortunately, traditional AC lter / conditioners have been designed for unrealistic laboratory conditions. Prior technologies, whether multipole lter or conventional series mode, could actually harm audio and video performance more than they helped, due to the resonant peaking of their antiquated, non-linear designs. Under certain conditions, these designs could actually add more than 10 dB of noise to the incoming AC line! Worse still, digital data loss, the need to re-boot digital pre-sets, or destruction of digital converters are frequently caused by excessive voltage spikes and AC noise contaminating the equipment ground. Furmans SMP+ with LiFT takes another approach, ensuring optimal performance with linear ltering and zero leakage to ground.
Furmans SMP+ surge suppression incorporates multiple protection technologies including MOVs along with a powerful lter to remove noise from the AC line, making it the most advanced and reliable power conditioning technology available. Unique to Furmans SMP+ is its unparalleled clamping voltage. While other designs clamp at voltages that are well above 450 Vpk, SMP+ clamps at 376 Vpk, (266 VAC RMS). This unprecedented level of protection is only available with Furmans SMP+ technology. Additionally, Furmans trusted over-voltage circuitry protects against those all-too-frequent accidental connections

Retractable Rack Lights, Rear Panel Lamp and Dimmer Control: The PL-PRO E II, PL-PRO PE II, PL-PRO DE II and PL-PRO PDE II include a dimmer control for the two retractable front panel light tubes. Turn it clockwise to increase brightness of both light xtures, or counterclockwise to decrease brightness. Turning the dimmer fully counterclockwise when the lights are not in use, will maximize the life of the LEDs: however, this is not absolutely necessary. Whether the light tubes are extended or ush with the front panel, our high-efciency, fullspectrum LEDs generate no appreciable heat. All Series II units feature a rear 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 power switch located on the far left of the front panel. Series II front panel LED lamps must be replaced by qualied Furman service personnel. Multi-Segment LED voltmeter: (PL-PRO E II and PL-PRO PE II) This three-color, 20-LED bar graph is an accurate, self checking AC voltmeter that continually measures normal voltages. The meter reads from 180 to 256 volts in 4 volt increments. Voltages within the normal range are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively. The voltmeter warns of abnormal conditions by ashing the LEDs in one of three special patterns. 1. If only the single leftmost LED (beneath the 180V mark) ashes, the input voltage is marginally low.

2. If all of the LEDs on the voltmeter ash, the input voltage is marginally high. The PL-PROs outlets will remain powered unless the incoming voltage rises above the Extreme Voltage Shutdown cutoff voltage of volts (UK version: V). 3. If none of the LEDs on the voltmeter are lit, and the Extreme Voltages LED indicator is illuminated, then the PL-PRO Series II has shut down power to its outlets because the input voltage is in excess of 280 volts (UK version: 260 V). Digital Voltmeter: (PL-PRO DE II, PL-PRO PDE II, PM-PRO E II and PM-PRO PE II) Furmans laboratory-precision AC digital voltmeter continually measures incoming voltages, with a typical tolerance of +/-1.5VAC. It should be noted that the voltage is read at the AC mains input. No adjustment should be necessary on these units. Digital Current Meter: (PM-PRO E II and PM-PRO PE II) Furmans laboratory-precision AC digital current meter continually measures the total circuit AC load, with 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).
NOTE: Your Series II Power Conditioner does not compensate for high or low line voltage. If you frequently move your rack to different locations, derive power from generators, use long extension cords, travel internationally, or are in an area prone to brownouts, you may benet from the use of one of Furmans AC Line Voltage Regulators. On/Off Circuit Breaker: This 16 amp capacity magnetic circuit breaker switch is specically designed to stand up to the enormous high inrush current demands of many power ampliers. Additionally, the switch is shielded from accidental power disconnection with a hinged cover. Extreme Voltage Shutdown Indicator: This LED is normally off. It monitors a hazard common in the entertainment industry: wiring faults for example, accidental connection to 380 VAC where 240VAC is expected. The Series II SMP+ 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 LED will light if the input voltage is above the extreme voltage cutoff, and power will not be applied to the units outlets. If the unit has been operating with an acceptable input voltage and subsequently that voltage exceeds 280V, it will shut off power to the outlet and the Extreme Voltage LED will light.
Protection OK Indicator: Although the Furman SMP+ circuit assures virtually impregnable protection against transient voltage spikes and surges, Nature occasionally creates electrical forces that are beyond the capacity of any TVSS device to absorb without incurring some degree of damage. In the rare instance that this occurs, the green Protection OK LED indicator located on your front panel will dim. Some level of protection from voltage surges will remain, but the clamping voltage rating will be compromised. The unit must be returned to Furman Sound or to an authorized Furman Service center for repair. NOTE: If the mains power is above the high cutoff voltage and has caused the unit to remove power from its outlets, it cannot restore power until the operator manually turns the unit off, then on again. Before turning the unit back on, always check the source of the problem, and change the AC source if necessary. Action Needed: Remove one piece of equipment from the Series II unit, open the hinged switch / breaker cover, and reset the switch to the on position. 2.) Symptom: No power to the AC outlets, Protection OK indicator is not lit. Possible Cause: Either the AC outlet to which your Series II device is connected has no AC voltage present, or the unit has been subjected to a sustained voltage in excess of 400 Volts. Action Needed: Plug the Series II unit into an AC receptacle where AC voltage is present. If the problem persists, the protection circuit may be damaged, and require factory service. 3.) Symptom: Extreme Voltage indicator lit. Possible Cause: Input voltage is above volts, causing power to the units outlets to be shut down. Additionally, at turn on, the unit will not allow AC voltage to reach the outlets. Action Needed: Correct the line voltage, then; turn the unit on. Consider installing a Furman voltage regulator.

1.) Symptom: No power to the AC outlets. Possible Cause: Circuit breaker switch has tripped to the off position, due to excessive load.
SERIES II 16 AMP POWER CONDITIONERS DEFINITIONS
SPIKE: A pulse of energy on the power line. Spikes can have voltages as high as 6000 volts. Though they are usually of very short duration, their energy can be considerable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and degrade wiring insulation. They are an unavoidable component of electric power. They are caused unpredictably by electric motors (on the premises or outside) switching on or off, or by utility company maintenance operations, lightning strikes and other factors. Spikes (also called surges or transients) are absorbed by special components in the SMP+ circuitry to maintain safe voltage levels and protect your equipment. RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not likely to cause damage, but it can certainly be annoying, producing static in audio circuits, snow on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and other sources. Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effectively reduced by low-pass lters.
