I N T R O D U C T I O N  
until the over-voltage condition is corrected.  
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 Furman’s  
revolutionary SMP+ circuitry, as well as our  
exclusive Linear Filtering Technology (LiFT).  
Together, SMP+ and LiFT comprise what is,  
without question, the world’s most advanced  
and comprehensive transient voltage surge  
suppressor / conditioner.  
LiFT (Linear Filtering Technology)  
Unfortunately, traditional AC filter / conditioners  
have been designed for unrealistic laboratory  
conditions. Prior technologies, whether multi-  
pole filter 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.  
Furman’s SMP+ with LiFT takes another  
approach, ensuring optimal performance with  
linear filtering and zero leakage to ground.  
SMP+  
Furman’s SMP+ surge suppression  
incorporates multiple protection technologies  
including MOV’s along with a powerful filter to  
remove noise from the AC line, making it the  
most advanced and reliable power conditioning  
technology available. Unique to Furman’s  
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 Furman’s  
SMP+ technology. Additionally, Furman’s  
trusted over-voltage circuitry protects against  
those all-too-frequent accidental connections

light power switch located on the far left of the  
front panel.  
Retractable Rack Lights, Rear Panel Lamp  
and Dimmer Control:  
Series II front panel LED lamps must be  
replaced by qualified Furman service  
personnel.  
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 fixtures, 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 flush  
with the front panel, our high-efficiency, full-  
spectrum LEDs generate no appreciable heat.  
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 flashing the LEDs in  
one of three special patterns.  
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

2. If all of the LED’s on the voltmeter  
flash, the input voltage is marginally  
high. The PL-PRO’s outlets will remain  
powered unless the incoming voltage rises  
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  
above the Extreme Voltage Shutdown cutoff long extension cords, travel internationally, or  
voltage of 270 – 280 volts (UK version:  
255 – 260 V).  
are in an area prone to brownouts, you may  
benefit from the use of one of Furman’s AC  
Line Voltage Regulators.  
3. If none of the LED’s 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).  
On/Off Circuit Breaker:  
This 16 amp capacity magnetic circuit breaker  
switch is specifically designed to stand up to  
the enormous high inrush current demands  
of many power amplifiers. Additionally, the  
switch is shielded from accidental power  
disconnection with a hinged cover.  
Digital Voltmeter:  
(PL-PRO DE II, PL-PRO PDE II, PM-PRO E II  
and PM-PRO PE II)  
Furman’s 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.  
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 unit’s 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.  
Digital Current Meter:  
(PM-PRO E II and PM-PRO PE II)  
Furman’s 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).

SERIES II 16 AMP POWER CONDITIONERS  
Protection OK Indicator:  
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.  
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.  
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.  
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.  
Possible Cause: Input voltage is above 270  
– 280 volts, causing power to the unit’s 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.  
TROUBLE SHOOTING GUIDE  
1.) Symptom: No power to the AC outlets.  
Possible Cause: Circuit breaker switch has  
tripped to the off position, due to excessive  
load.

DEFINITIONS  
THREE YEAR LIMITED  
WARRANTY  
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.  
Furman Sound, Inc., having its principal place  
of business at 1997 South McDowell Blvd.,  
Petaluma, CA 94954 (“Manufacturer”) warrants  
its 16 amp Series II Power Conditioners (the  
“Product”) as follows:  
Manufacturer warrants to the original  
Purchaser of the Product that the Product sold  
hereunder will be free from defects in material  
and workmanship for a period of three years  
from the date of purchase. The Purchaser  
of the product is allowed fifteen days from  
the date of purchase to complete warranty  
registration by mail or on-line at the Furman  
website. If the Product does not conform to this  
Limited Warranty during the warranty period  
(as herein above specified), Purchaser shall  
notify Manufacturer in writing of the claimed  
defects. If the defects are of such type and  
nature as to be covered by this warranty,  
Manufacturer shall authorize Purchaser to  
return the Product to the Furman factory or to  
an authorized Furman repair location. Warranty  
claims should be accompanied by a copy of  
the original purchase invoice showing the  
purchase date; this is not necessary if the  
Warranty Registration was completed either via  
the mailed in warranty card or on-line website  
registration. Shipping charges to the Furman  
factory or to an authorized repair location must  
be prepaid by the Purchaser of the product.  
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 filters.
