Profile: Furman Sound specializes in audio and video signal processors. Our products include 120V pro audio & video, 120 home theater, and 220-240V products. Our classic series from Furman brings together superior protection and outstanding performance in a sturdy, rack-mountable design. The classic series features revolutionary series multi-stage protection (SMP), linear filtering technology (LiFT), and extreme voltage shutdown (EVS). Our PL-8 C power conditioner is used for recording and pro audio equipment. Our 15 Amp P-1800 AR delivers a stable 120 volts of AC power to protect equipment from problems caused by AC line voltage irregularities such as sags, brownouts, or overvoltages - all of which can cause sensitive electronic equipment to malfunction, or sustain damage. The P-1800 AR accepts input voltages over a wide AC voltage range, and transforms them to a constant output of 120V, ±5V. Voltages beyond that range may also be converted to usable levels, depending on the range variance. The P-1800 AR is a full-featured power conditioner that filters and purifies AC power, reducing line noise and ensuring optimum performance. It can also be fully protected by our exclusive series multi-stage protection (SMP), and extreme voltage shutdown (EVS). This circuitry provides the highest level of power protection available.
