Stable Power Regulation


With today’s chaotic demands on many municipal power facilities, AC voltage is often reduced so that it can be stretched to fulfill excess demand. This creates a substantial negative impact on your system’s performance. Power amplifiers and powered subwoofers cannot perform to their full potential.

Even a relatively modest reduction in AC voltage can obliterate the sonic impact of an otherwise superior system. Low voltage can also burn out a component’s power supply because the internal power supply must work harder to make up for the lack of incoming voltage.

Just as problematic are the excessively high line voltages. Excess voltage can overheat sensitive electronics, lower the life and reliability of projector lamps and cause many circuits to shut down.

The incoming voltage (120V on the line terminal and 0V on the neutral and ground) is split into perfect halves on the transformer’s output. The AC line now has 60V on the line and 60V on the neutral when referenced to the new center-tapped ground which remains at 0V AC.

Stable Power

With Furman’s exclusive Stable Power Regulation Technology, incoming voltages that are either too low or dangerously high are converted into a stable, steady, 120V AC (typically ±1V). This allows a voltage-starved system to perform at its full potential. Electronic components are supplied with constant, unwavering AC voltage, assuring trouble free service for any environment suffering from unstable power.

Furthermore, Furman’s Stable Voltage Regulation generates virtually no heat and produces none of the mechanical noise typical in inferior AC voltage regulators. Our zero-crossing, solid state technology, provides virtually unlimited peak current delivery. This helps avoid the current limiting found in AC regulators that convert AC power into DC, and then synthesize an AC output signal.

Everything works 100% of the time

With this gear I can crank up the monitors without hearing line noise. It also helps to make the transmission pure by ensuring every piece of gear operates at its optimal level.
