I N T R O D U C T I O N
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.
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
to 380 VAC, by shutting off the incoming power
until the over-voltage condition is corrected.
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.

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 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.
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 qualified 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 flashing the LEDs in
one of three special patterns.
1. If only the single leftmost LED (beneath
the 180V mark) flashes, the input voltage is
marginally low.
6
Multi-Segment LED Voltmeter Readings

SERIES II 16 AMP POWER CONDITIONERS

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
above the Extreme Voltage Shutdown cutoff
voltage of 270 – 280 volts (UK version:
255 – 260 V).
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).
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.
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).
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
benefit from the use of one of Furman’s AC
Line Voltage Regulators.
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.
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.

SERIES II 16 AMP POWER CONDITIONERS
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.
T R O U B L E S H O O T I N G G U I D E
1.) Symptom: No power to the AC outlets.
Possible Cause: Circuit breaker switch has
tripped to the off position, due to excessive
load.
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 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.

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 filters.
