The Furman P-1800 AR is a premier 15-amp voltage regulator and power conditioner that actively maintains a constant 120V output regardless of what the power grid delivers — making sags, brownouts, and voltage spikes non-issues for your studio gear. No matter where you plug in, the P-1800 AR feeds your rack a steady, regulated supply of clean power backed by Furman's full protection suite including Linear Filtering Technology, Series Multi-Stage Protection, and Extreme Voltage Shutdown. For recording engineers and touring professionals who can't afford to gamble on local power quality, the P-1800 AR is the definitive solution.

True RMS Voltage Regulation

• Constant 120V output: True RMS Voltage Regulation Technology actively corrects incoming voltage across a 97–137V input range, delivering a steady 120V to every connected device.
• Brownout protection: Maintains regulated output during voltage sags that would cause equipment to malfunction, reboot, or sustain damage.
• Swell correction: Clamps high-voltage swells before they reach your gear.

Power Conditioning

• Linear Filtering Technology (LiFT): Purifies AC power by eliminating line noise, reducing the noise floor across your entire connected rig.
• Series Multi-Stage Protection (SMP): Advanced multi-stage surge suppression for maximum protection against transient spikes.
• Extreme Voltage Shutdown (EVS): Automatically disconnects all outlets when sustained overvoltage conditions are detected.

Monitoring & Connectivity

• LED voltmeter and ammeter: Front-panel displays for real-time voltage and current monitoring.
• USB-A port: Front-panel charging for mobile devices.
• Rear BNC connector: Supports a gooseneck rack lamp (lamp not included).
