INTRODUCTION

Congratulations on your purchase of a
Furman Power Factor Pro (Model PF­Pro or PF-Pro R. The Power Factor Pro

features Furman’s revolutionary Clear Tone

Technology, Series Multi-Stage Protection

Plus (SMP+) circuit, as well as our exclusive
Linear Filtering Technology (LiFT). Together
these technologies comprise the world’s

rst comprehensive AC power conditioner for
instrument ampliers.

Today’s AC power is contaminated. Whether

you play in a stadium, bar, or rehearsal
space, they all have one thing in common:
the AC power is supplied from your local
utility. What’s worse is that the “power factor”
supplied from your building’s AC outlet is
typically poor, thanks to increasingly over
taxed power lines and raised line impedance.

In fact, the quality of AC power has been so
poor for so long, most musicians have no idea

how great their ampliers could really sound.
When the AC power factor is poor, ampliers

sound muddy because their power supplies
can’t deliver when pushed. The scream and
cry from a guitar loses bite and harmonics,
bass guitars lose their punch and weight,
keyboards sound nasally, losing clarity, attack,
and extension.

Furman’s Power Factor Pro addresses this

issue - allowing your amplier to sound its best

while protecting it at the same time.

DESCRIPTION

The Power Factor Pro’s “Clear Tone
TechnologyTM” actually lowers the AC line

impedance supplied by your wall outlet, while
storing energy for peak current demands. In
fact, there are over 45 amps of instantaneous
current reserve in the Power Factor Pro.
Additionally, “Linear Filtering TechnologyTM”
dramatically lowers AC line noise to
unprecedented levels in the critical audio
frequency band. What does this mean? Just

plug in your current-starved amplier, crank

up the volume, and listen to the dynamics,

harmonics, and clarity you’ve been missing!

Additionally, the Power Factor Pro is the most
comprehensive power conditioner ever created
for the serious musician. Furman’s Series
Multi-Stage Protection Plus (SMP+) guards
your equipment from voltage spikes that can

damage your amplier or other connected

equipment.

Furman’s SMP+ features unparalleled
clamping voltage. While other designs offer
clamping voltages that are well above 330Vpk,
Furman’s SMP+ clamps at 188Vpk (133 VAC
RMS) even when tested with multiple 6000Vpk

- 3000 amp surges! And, our pro level over­voltage auto shutdown circuit assures you will

never see your prized amplier go up in ames

due to a sustained voltage overload.

The PF-Pro has a generous 12 amp R.M.S.

capacity, a convenient 20 segment AC
voltmeter, a detachable-locking AC cord,
and (4) AC outlets, all contained in a small

convenient, oor standing package. The PF-

Pro R has the same features except its cord
is not detachable and it has (8) rear outlets
and (1) front panel outlet. It also features
a BNC connector on the rear panel to allow
attachment of any standard gooseneck lamp
(such as Furman’s model GN-I or GN-LED) to
illuminate the rear of your rack.

F E A T U R E S

The Power Factor Pro has a master switch for

the rear outlets that glows red when the power

is on. The circuit breaker is located adjacent to

the power switch for the PF-Pro and on the rear
panel for the PF-Pro R. It can be quickly and
easily reset should the unit be overloaded. The

PF-Pro also features a detachable 10 foot, 14

gauge heavy-duty power cable.

The Power Factor Pro, offers a 20 segment

LED bar-graph meter that displays incoming
voltage between 90 and 128 volts in 2-volt
increments. The normal range voltages are
indicated in green, with moderately and
extremely high or low voltages in yellow and
red respectively. The voltmeter’s accuracy
is ±2 volts. It can easily be recalibrated, if
necessary.

The PF-Pro R features 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 power switch
located on the far left of the front panel.

O P E R AT I O N

Multi-Segment LED Voltmeter:

This three-color, 20-LED bargraph is an

accurate, self checking AC voltmeter that
continually measures input voltages. The
meter reads from 90 to 128 volts in 2 volt
steps (Power Factor 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. The voltmeter provides three

special ashing patterns to indicate abnormal

conditions.

(1) On initial turn on, the voltmeter will

scan for smart chip integrity.

(2) If only the single leftmost (beneath

the 90V mark) LED ashes, the input

voltage is marginally low.

POWER FACTOR PRO MANUAL

4

(3) If all of the LEDs on the voltmeter

ash, the input voltage is marginally

high. Power to the Power Factor
Pro’s outlets will remain on unless the
incoming voltage rises above the
Extreme Voltage Shutdown (EVS)
cut-off voltage (135 - 140 volts).

The Power Factor Pro’s 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
Power Factor Pro E).

NOTE: Although the Power Factor correction

will more than compensate for peak current
demands, the Power Factor Pro does not
compensate for sustained high or low line
voltage. If you derive power from generators,
travel internationally, or are in an area prone

to extreme brownouts, you may benet from

the use of one of Furman’s AC Line Voltage
Regulators.

On/Off Rocker Switch:

This 15 amp capacity power switch is

specically designed to stand up to the

enormous high inrush current demands placed

by many instrument ampliers. Additionally, the

semi-transparent rocker lights when switched

to the “ON” position.

Extreme Voltage Shutdown (EVS) Indicator:

This LED is normally off. It monitors a hazard

unfortunately common in the entertainment
industry: wiring faults – for example, accidental
connection to 220VAC where 120VAC is
expected, or an open neutral from a 208 or
240VAC feed. The Power Factor Pro’s 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 be lit 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 then that
voltage goes above 135V, it will shut off power
to the outlet and the Extreme Voltage LED will
light.

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 without the operator manually turning
the unit off, then on again. Avoid turning the
unit back on without checking the source of the

problem rst, and perhaps changing the AC

source.

1.) Symptom: No power to the AC outlets.

Possible Cause: Circuit breaker has

tripped due to excessive load.

Action Needed: Remove one piece of
equipment from the Power Factor Pro unit,
and push the square re-set tab into the circuit
breaker bezel.

2.) Symptom: No power to the AC outlets,

“Protection OK” indicator is not lit.

Possible Cause: Either the AC outlet that

your Power Factor Pro device is connected

to has no AC voltage present, or the unit has
been subjected to a sustained voltage in
excess of 400 volts.

Action Needed: Plug the Power Factor
Pro unit into an AC receptacle where AC
voltage is present. If the problem persists, the
protection circuit may be damaged factory
service may be required.

3.) Symptom: Extreme Voltage indicator lit.

Possible Cause: Input voltage is above

135 - 140 volts, causing power to the unit’s

outlets to be shut down. Additionally, if the
voltage is below 85-90 volts 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.

Important Note:

The Power Factor Pro must be the rst AC power component connected to the AC mains!

Regulators such as the Furman AR-1215 or UPS systems such as the SB-1000 must be
connected to the Power Factor Pro’s output. This is due to the fact that the PF-Pro’s current
reservoir may hinder the performance of a regulator, and worst case may cause damage in
extreme power environments.

As long as the Power Factor Pro is connected prior to the Regulator or UPS both components
may be used.
