The Furman GFCI detects any imbalance in the current flowing in the two hot legs The missing current is presumed to be flowing through the ground conductor the round pin on anAC outlet Ground current often indicates a dangerous partial or full short circuit If an imbalance is detected the GFCI will trip the main circuit breaker power switch To restore operation correct the fault and turn the unit on again 5 mA of current is enough to cause the GFCI to trip to troubleshoot this type of problem start with nothing connected to the IT Reference 16 E Then add each piece of equipment until the GFCI trips Contact the manufacturer of the suspect unit for possible solutions Suggested AC Connection Surround Cable Satellite Powered Plasma Sound Video Protector Subwoofer LCD Monitor Processor Projector CABLE SATELLITE TRANSIENT VOLTAGE SURGE S PPRESSION 0 6 60 aw S our 6 our y our 6 E07 7773 POWER AMPLIFIERS HIGH CURRENT ULTRA LOW IMPEDANCE LINEARLY FILTERED AC POWER PROTECTION OK zame INDICATOR BREAKER 6 symmemcaL DM POWER Sins DESIGNED TESTED AND ASSEMBLED 16 AMPS MAX INUSA 16 Amp 5 7 Outlet Channel Amplifier Testing the IT Reference 16 E s GFCI once a year is recommended Simply press the button marked GFI TEST If the GFCI is functioning properly this will cause the main circuit breaker power switch to trip and cut off power After verifying the GFCl s prope2. into a system s critical components it masks low level signals and cripples performance This low level content is critical because it relays the crucial harmonics and ambience in audio and depth and clarity in video With the IT Reference 16 E s exclusive Discrete Symmetrical Power video screens projectors CD DVD players pre amplifiers and scalers are fed linearly filtered ultra low noise Discrete Symmetrical Power This dramatically reduces AC noise ensuring peak operation of your critical components For the first time you will see and hear your theater or audio system as it should be uncompromised Further our Discrete Symmetrical Power features total isolation between three discrete AC outlet banks This positively breaks noise inducing ground loops hum bars and power supply backwash between interconnected equipment all without compromising electrical safety This enables a plasma screen to function without AC ground contamination from a compact disc player or a preamplifier processor to function free of performance degrading digital noise from a satellite receiver The IT Reference 16 E also employs our unique Power Factor Correction Circuit For the first time low level analog digital and video components are not modulated or distorted via the power amplifier s extreme AC current demands Further the power amplifier sees a highly filtered extremely low impedance supply of AC power The IT Referenc
