Please email prior to bidding  "Used" Furman AR1220 AC Line Voltage Regulator Power Conditioner for better production/performance needs in the Studio, Broadcast TV/Film, Home Audio Enthusiast, and Live Performance. Designed to protect sensitive equipment. As can be seen in the pictures the unit is in great shape with exception to rack rash on the four ear holes. 20 AMP Plug for power not 110V as standard USA plugs are Note: Because of its 20 amp rating, the AR-1220 uses a special AC plug. This is one the the best voltage regulating units ever built and is of professional quality and is a need for higher and better production needs. When your gear runs smoother it performs optimally an produces higher quality results with less equipment faults and failures. New this unit was very expensive now no longer in production. Built in the USA. "Come on USA - Get back In The Game!"Noise Attenuation:

The Furman AR-1220 AC Line Voltage Regulator has been designed specifically with the unique needs of audio and video in mind! The 20 amp AR-1220 protects audio, video, computer and other electronic equipment from problems caused by AC line voltage irregularities - sags, brownouts, or overvoltages that can cause sensitive digital equipment to malfunction, or, in extreme cases, to sustain damage. The AR-1220 accepts input voltages from 97V to 141V and transforms them to a steady, stable 120 VAC (±5V) output. Voltages beyond that range may also be converted to usable levels, depending on how far out of range they are. The AR-1220 can handle loads totaling up to 20 amps as long as the input voltage is above 124 volts. Unique technology optimized for audio and video use The AR-1220's technology differs from that of computer-oriented voltage regulators in many important ways: the AR-1220 does not use a ferro-resonant transformer, so it's not heavy and bulky, doesn't radiate a large magnetic field, and isn't too frequency-sensitive to be usable with generators. Instead, it uses a design based on an eight-tap toroidal autoformer. The toroidal design assures minimal leakage of stray magnetic fields. The AR-1220 circuitry monitors the incoming line voltage with each cycle, comparing it to an extremely precise voltage reference, accurate to ±0.15%. If a voltage fluctuation requires that a different tap be selected, the new tap is electronically switched exactly at the zero-crossing, to avoid distorting the AC waveform. (Most commercial voltage regulators using multiple-tapped transformers switch taps at uncontrolled times, thereby creating voltage spikes, and often creating clicks that can leak into the audio.) Hysteresis of 1.5V in the switching circuits avoids "chatter." The design is not sensitive to small errors in line frequency, making the AR-1220 ideal for use with generators. The AR-1220 also features power conditioning that is truly in a class by itself, thanks to the quantity, quality and configuration of the overvoltage suppression devices used. These include MOV's, high voltage inductors and capacitors, and precise high-inrush magnetic circuit breakers. This unique combination can safely divert large spikes as well as filter audible high frequency noise. An additional feature, Extreme Voltage Shutdown, senses dangerously high or low voltages and shuts down the output before any damage is done. The output remains off until the overvoltage or undervoltage is removed, with an LED indicating the shutdown condition. This invaluable feature provides positive protection to your equipment from accidental connection to incorrect line voltages (for example, 220V when 120V is expected - a not uncommon hazard in the entertainment industries. Plenty of outlets and simple controls The AR-1220 has 12 outlets on the rear panel, and two on the front panel. All outlets are regulated, spike-su
