Furman Sound Begins Shipping AR-20 II

Furman Sound has begun shipping its AR-20 II, a new 20-amp regulator that delivers 120 volts of AC power to protect equipment from damaging AC line voltage irregularities, while filtering and purifying AC power to ensure the optimal performance of connected equipment.

Furman’s AR-20 II accepts input voltages from 97V to 141V and transforms them to a constant 120V. The AR-20 II compares the incoming line voltage to a voltage reference and switches taps electronically at the zero-crossing to avoid distorting the AC waveform.

The regulator also is outfitted with Furman’s proprietary Series Multi-Stage Protection Plus (SMP+) technology, which combines three filtering and protection circuits: Linear Filtering Technology (LiFT) suppresses noise across the entire dynamic range; Series Multi-Stage Protection (SMP) clamps and dissipates damaging transient voltages at the highest degree available without sacrificing itself; and Extreme Voltage Shutdown (EVS) circuitry protects against prolonged over-voltages by shutting off the incoming power until the over-voltage condition is corrected.

Housed in a compact dual-space, rackmount chassis, the AR-20 II features 12 outlets on the rear panel and two outlets on the front panel. All 14 outlets are regulated, spike-suppressed and filtered against radio frequency and electromagnetic interference.

The unit features a digital meter that indicates input voltage, an LED that indicates when the output voltage is within regulation and an on/off switch. It is protected by a limited three-year warranty covering defects in materials and workmanship.
