Furman Sound AR-15 manual Voltage Regulation, SMP+ Series Multi-Stage Protection Plus

AR-15 Voltage Regulator / power conditioner

AR-15. To prevent risk of fire or injury, dam- aged cords and cables should be replaced immediately.

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 Multi-Stage 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,
