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

AR-15 specifications

Furman Sound AR-15 is a highly regarded power conditioner specifically designed for professional audio applications. This device plays a crucial role in maintaining the integrity of audio and video systems by providing a stable and clean power source. One of its main features is its ability to filter out noise and voltage spikes, which can cause interference and potentially damage sensitive equipment.

One of the standout technologies in the AR-15 is its Linear Filtering Technology (LiFT). This advanced filtering process significantly reduces common-mode and differential-mode noise, ensuring that the audio signal remains pristine. The result is a dramatically improved sound quality that professionals rely on in live performances, recording studios, and broadcast applications.

Another key characteristic of the Furman AR-15 is its durable construction. Built with rugged metal housing and a design that focuses on durability, the device is well-suited for the rigors of touring and frequent relocations. Its compact 1U rack-mount design allows for easy integration into standard equipment racks, making it a convenient choice for professionals looking to streamline their setups.

The AR-15 also features a series of outlets, which include 10 filtered and surge-protected AC outlets. This allows users to connect multiple devices while ensuring they are all protected from surges and spikes. Additionally, the device has a built-in LED voltage meter that provides real-time information on the incoming voltage levels, enabling users to monitor their power conditions accurately.

To further enhance usability, the device includes a front panel with resettable circuit breakers, which provide protection against overloads while being easy to reset in case of an issue. This ensures that users can maintain uninterrupted operation, allowing for a seamless performance.

In conclusion, the Furman Sound AR-15 is a powerful and reliable tool for audio professionals. With its advanced filtering technology, durable design, and thoughtful features, it provides an essential safeguard for audio equipment, ensuring optimal performance and longevity. Whether for live sound, studio recording, or broadcast applications, the AR-15 stands as a trusted partner in achieving top-notch audio quality.
