AR-15 II VOLTAGE REGULATOR / POWER CONDITIONER
Congratulations on your purchase of a
Furman AR-15 II AC Line Voltage Regula-
tor / Power Conditioner. The AR-Series
regulators are designed specically for
any audio, video, or computer rackmount
system requiring clean, ltered, and regu-
lated AC power for optimum operation.
AR-15 II FEATURES
• Provides nine regulated, conditioned AC
outlets—eight on the rear panel and one on
the front
• Series Multi-Stage Protection Plus
(SMP+) with extreme voltage shutdown
(EVS)
• LiFT (Linear Filtering Technology) with
zero ground contamination
• BNC connector on the rear panel allows
you to attach any standard (12VAC 0.5
amp) gooseneck lamp to illuminate the
rear of your rack
• Extreme Voltage Shutdown indicator LED
• Output In Regulation indicator
• Ten-LED bargraph input voltmeter
• Fast-acting user-accessible circuit breaker
protects against overload or shorts
• Very low stray magnetic eld leakage
• Input capacity is 15 A; output capacity is 12
to 15 A
SAFETY INFORMATION
To obtain best results from your Furman AR-15 II
please be sure to read this manual carefully.
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. There are no user serviceable parts inside.
Refer servicing to qualied personnel only.
IMPORTANT SAFETY
INSTRUCTIONS
PLEASE READ PRIOR TO INSTALLATION
1. Please read and observe all of the safety and
operating instructions before the AR-15 II is
operated. Retain these instructions for future
reference.
2. The AR-15 II should not be used near water
— for example, near a bathtub, kitchen sink, in
a wet basement, near a swimming pool, etc.
3. Do not place the AR-15 II near heat sources
such as radiators, heat registers, stoves, or
other appliances that produce heat.
4. 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 AR-15 II. To prevent risk of re or injury,
damaged cords and cables should be replaced immediately.
5. Clean the AR-15 II with a damp cloth only. Do
not use solvents or abrasive cleaners. Never
pour any liquid on or into the unit.
6. When left unused for a long period of time,

the power cord of the AR-15 II should be
unplugged from the outlet.
7. The AR-15 II should be serviced by qualied
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 AR-15 II has been exposed to rain or
other moisture.
d. The AR-15 II does not appear to operate
normally or exhibits a marked change in
performance.
e. The AR-15 II has been dropped, or the
enclosure damaged.
8. The AR-15 II requires that a safety ground be
present for proper operation. Any attempt to
operate the AR-15 II without a safety ground
is considered improper operation and could
invalidate the warranty.
9. There are no user serviceable parts in the
AR-15 II. Refer servicing to qualied service
personnel only.
Voltage Regulation
Furman Voltage Regulators are intended to
protect sensitive electronic equipment from
problems caused by AC line voltage irregularities—brownouts or overvoltages that can
cause audio tonal changes, digital equipment
malfunction (such as loss of MIDI programs or
other data), or, in extreme cases, permanent
damage. They accept input voltages over a
wide AC voltage range and convert them to a
steady, stable output at the desired standard
voltage, plus or minus ve volts. Voltages approximately ±10% beyond that range may be
converted to usable levels, depending on the
requirements of the equipment. This stable
voltage protects equipment and allows optimal
performance. See graphs on the back page.
The AR-15 II has eight outlets on the rear
panel, and one convenience outlet on the front
panel. All are functionally interchangeable. The
outlets are regulated, surge-suppressed, and
linearly ltered, making the unit a full-function
power conditioner. The AR-15 II has no controls except an on-off switch and the switch for
the optional rear rack light.
Note: The AR-15 II is for use with AC voltage
only. DC voltages should never be applied to
them. Also, it does not change or regulate line
frequency. The output frequency will always be
the same as the incoming frequency.
SMP+ (Series Multi-Stage Protection
Plus)
Traditional surge suppression rely on circuits
that “sacrice” themselves when exposed to
multiple transient voltage spikes, requiring the
dismantling of your system, and repair of your
surge suppressor. Not so with SMP+. With
Furman’s SMP+, damaging transient voltages
are safely absorbed, clamped, and dissipated.
No sacriced parts, no service calls, no down
time.
Unique to Furman’s SMP+ is its unparalleled
clamping voltage. While other designs offer
clamping voltages that are well above 330 Vpk,
Furman’s SMP+ clamps at 188 Vpk, (133 VAC
RMS). This unprecedented level of protection
is only available with Furman’s SMP+ technology. Additionally, Furman’s trusted over-voltage circuitry protects against all too frequent
accidental connections to 208 or 240 VAC, by
shutting off the incoming power until the over
voltage condition is corrected.
