AR-15 VOLTAGE REGULATOR / POWER CONDITIONER

5.  Clean the AR-15 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 should be un-

plugged from the outlet. 

7. The AR-15 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 AR-15 has been exposed to rain or 

other moisture. 

d. The AR-15 does not appear to operate 

normally or exhibits a marked change in 

performance. 

e. The AR-15 has been dropped, or the 

enclosure damaged.

8. The AR-15 requires that a safety ground be 

present for proper operation. Any attempt to 

operate the AR-15 without a safety ground 

is considered improper operation and could 

invalidate the warranty.

9. There are no user serviceable parts in the 

AR-15. Refer servicing to qualified service 

personnel only. 

Voltage Regulation 

Furman Voltage Regulators are intended to 

protect sensitive electronic equipment from 

problems caused by AC line voltage irregu-

larities—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 five volts. Voltages ap-

proximately ±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 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 

filtered, making the unit a full-function power 

conditioner. The AR-15 has no controls except 

an on-off switch and the switch for the optional 

rear rack light. 

Note: The AR-15 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 mode protection 

plus

)

Traditional surge suppression rely on circuits 

that “sacrifice” 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 sacrificed 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+ technol-

ogy.  Additionally, Furman’s trusted over-volt-

age circuitry protects against all too frequent
