Furman Sound begins shipping AR-20 II
October 8, 2006
Furman Sound announced it has begun shipping its AR-20 II. The new 20-amp regulator delivers a stable 120V of AC power to protect equipment from AC line voltage irregularities, while filtering and purifying AC power to ensure the optimal performance of connected equipment.
The AR-20 II accepts input voltages from 97V to 141V, and transforms them to a constant 120V. Unlike voltage regulators that use motorized transformer-based technology and switch taps at uncontrolled times — creating voltage spikes and clicks that can leak into the audio — the AR-20 II compares the incoming line voltage to an extremely precise voltage reference and switches taps electronically at the zero-crossing to avoid distorting the AC waveform.
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 has a digital meter to indicate input voltage, an LED to indicate the output voltage is within regulation and a single control: the on/off switch. It is protected by a limited three-year warranty.
