Description

When it comes to protecting your valuable audio equipment, the Furman Sound AR-PRO AC Line Voltage Regulator stands as a beacon of reliability and precision. Engineered to shield your gear from the unpredictable nature of AC line voltage fluctuations, this voltage regulator ensures your setup remains unscathed by sags, brownouts, or overvoltage conditions. With the ability to accept input voltages ranging from 97V to 141V and transform them into a consistent 120 VAC (±5V) output, the AR-PRO offers peace of mind for both studio and live settings.

What sets the AR-PRO apart is its unique eight-tap toroidal autoformer design, which minimizes magnetic field leakage, offering a sleek and efficient alternative to conventional bulky transformers. Unlike typical voltage regulators, its precise voltage reference circuit ensures a steady performance, switching taps only at zero-crossing points to prevent waveform distortion. This meticulous attention to detail makes it ideal for audio and video applications, where precision is paramount.

The AR-PRO also features robust power conditioning, thanks to its high-quality overvoltage suppression devices. Whether it’s diverting large spikes or filtering high-frequency noise, the AR-PRO is equipped to handle it all. With 12 outlets on the rear and two up front, your setup remains organized and efficient. Its Extreme Voltage Shutdown feature adds an extra layer of safety, automatically disconnecting power if dangerous voltage levels are detected, thus protecting your sensitive equipment.

Key Features:

  • Stabilizes input voltages between 97V and 141V to a reliable 120 VAC (±5V)
  • 20 amp output capacity
  • 12 regulated, spike-suppressed rear outlets and 2 front outlets
  • 10-LED bar-graph meters for input voltage and output current monitoring
  • Extreme Voltage Shutdown for overvoltage/undervoltage protection
  • Low magnetic field leakage thanks to toroidal autoformer design
