The Furman Power Factor Pro R Clear Tone Power Conditioner is specifically designed to provide power conditioning for the guitarist, bassist, or keyboard player. The AC power nowadays supplied from local utilities is typically poor and contaminated. The Clear Tone Technology in this unit actually lowers the AC line impedance supplied by the wall outlet, while storing energy for peak current demands. There are over 45 amps of instantaneous current reserve in the Power Factor Pro R. Coupled with Linear Filtering Technology (LiFT), this dramatically lowers AC line noise in the critical audio frequency band.
SMP circuitry offers the highest degree of protection against electrical surges and spikes, and does this without sacrificing itself or any of its components. In addition, the Extreme Voltage Shutdown circuit automatically turns off the unit when it is fed 140 volts or higher, protecting itself and connected equipment from the extreme voltage.
The Power Factor Pro R offers a 20 segment LED bar-graph meter that displays incoming voltage between 90 and 128 volts in 2-volt steps. The normal range voltages are indicated in green, with moderately and extremely high or low voltages in yellow and red respectively. The voltmeter's accuracy is ±2 volts.
