AR-15 VOLTAGE REGULATOR / POWER CONDITIONER

The AR-15 can handle loads totalling up to 15 amperes as long as the input voltage is equal to or above 124 volts. For voltages below that level, its capacity must be derated at approxi- mately 113 milliamperes per volt. (See graphs on back page.) As a practical matter, therefore, to cope successfully with worst-case brown- out conditions, you should plan your total load so that it does not exceed 12 amps, or 1400 watts. Please note that this refers to the ag- gregate power requirement of all equipment plugged into the Voltage Regulator, not to each individual item.

NOTE: While there is no minimum load require- ment for the AR-15 you may experience an audible mechanical hum coming directly from the unit when the POWER switch is on with nothing plugged in. This effect will sometimes disappear as soon as you plug in any equipment drawing 40 to 50 watts total.

DEFINITIONS

VOLTAGE REGULATION: The AC line voltage is a number indicating the nominal electrical potential that has been adopted in a region for powering electrical equipment of all kinds. In most of North America it is 117 volts AC; in Japan, 100 volts; and in many other countries 220, 230, or 240 volts. The actual voltage can fall below or rise above this nominal level due to brownouts, power cutbacks, use of substan- dard wiring, and other causes. These devia- tions can cause poor performance or a mal- function. A regulator is a device which, through use of a transformer, corrects the voltage deviation by stepping it up or down so that it is as close as possible to the nominal level.

SPIKE: A pulse of energy on the power line. Spikes can have voltages as high as 6000

volts. Though they are usually of very short du- ration, the energy they contain can be consid- erable, enough to damage sensitive solid-state components in audio and computer equipment. Spikes can also foul switch contacts and de- grade wiring insulation. They are an unavoid- able component of electric power. They are caused unpredictably by electric motors switch- ing on or off (on the premises or outside), utility company maintenance operations, nearby lightning strikes, and other factors. Spikes (also called surges or transients) are absorbed by special components called MOV’s in the AR- series to provide safe voltage levels to protect your equipment.

RFI/EMI INTERFERENCE: Noise from RFI (Radio Frequency Interference) or EMI (Electro Magnetic Interference) involves lower voltages and less energy than is found in spikes, but it is continuous rather than transient in nature. It is not likely to cause physical damage, but it can certainly be annoying, producing static in audio circuits, “snow” on video screens, or garbled data in computers. Noise can be introduced into AC lines by nearby radio transmitters, certain kinds of lighting, electric motors, and others. Because noise occurs at higher frequencies than the 50 or 60 Hz AC line, it can be effective- ly reduced through use of low-pass filtering.

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.
