Overview

The Furman P-1800 AR is a professional-grade voltage regulator and power conditioner designed to deliver stable, clean AC power to sensitive audio, video, and electronic equipment. Its True RMS voltage regulation continuously monitors incoming power and corrects it to a steady 120-volt output, compensating for sags and surges across an input range of 97 to 137 volts. This level of regulation is essential in environments where power quality is unpredictable — whether on tour, in older buildings with inconsistent wiring, or in home studios sharing circuits with household appliances.

Beyond voltage regulation, the P-1800 AR incorporates Furman's SMP+ (Series Multi-Stage Protection Plus) surge protection, a non-sacrificial design that absorbs spikes without degrading over time, unlike the MOV-based protection found in consumer surge strips. The LiFT (Linear Filtering Technology) system filters AC line noise to reduce hum, buzz, and interference that can compromise audio clarity and video quality. For catastrophic power events, the EVS (Extreme Voltage Shutdown) circuit automatically shuts down the unit and all connected gear when voltage exceeds safe thresholds, then restores power once conditions normalize. The front panel includes USB charging outlets, and the 15-amp capacity comfortably handles most professional audio rigs, DJ setups, and home entertainment systems.

Key Features

True RMS voltage regulation - holds a stable 120 volts (plus or minus 5) from any input between 97 and 137 volts, protecting gear from sags and brownouts.

SMP/LiFT/EVS protection - non-sacrificial surge suppression, linear noise filtering and extreme-voltage shutdown for clean, safe power.

Digital voltmeter/ammeter - front metering shows incoming voltage and current draw in real time.

Nine outlets in isolated banks - eight rear (two isolated banks) plus one front convenience outlet, with a front-panel USB charger.

BNC gooseneck lamp connector - adds an optional gooseneck lamp for front-panel light.

Frequently Asked Questions

The P-1800 AR uses True RMS voltage regulation to continuously monitor incoming AC power and adjust it to a stable 120-volt output. This protects your equipment from voltage sags, surges, and brownouts that can cause performance issues or damage.
The unit's EVS (Extreme Voltage Shutdown) circuitry detects dangerous voltage conditions and safely powers down itself and all connected equipment to prevent damage, then restores power when conditions return to safe levels.
SMP+ (Series Multi-Stage Protection Plus) is Furman's non-sacrificial surge protection system. Unlike standard surge protectors that degrade over time, the SMP+ design absorbs and dissipates surges without wearing out, providing consistent protection over the life of the unit.
Yes, the front panel includes USB convenience outlets that allow you to charge media devices or power a USB lamp directly from the unit.
It is designed for instrument rigs, home recording studios, DJ setups, professional audio racks, and home entertainment systems — essentially any setup where clean, stable power is critical.
