4. ground fault protection This circuit ensures that even in the event of a catastrophic failure to the connected components power supply and or circuits demonstrated by full shorting and possible smoke there will be no AC voltage on the components chassis that could possibly shock a person This circuit instantly recognizes if there is more than 5mA of current leakage from Line to AC Ground or Neutral to AC Ground This is the maximum current allowed for ALL 8 of the Symmetrical AC outlets If this current leakage is detected the main power switch magnetic circuit breaker will immediately switch off thus protecting the system operator and all others that might come in contact with the system It is very rare for this circuit to trip If it does the connected component that causes this is either defective most likely or it and possibly another component on the same Symmetrical Power bank may have a combined current leakage to ground that exceeds 5mA Technically this is not allowed in modern electronic circuit design but that does not necessarily mean an otherwise well performing product with an unconventional power supply is unsafe to use Such a component may need to be used with either the Niagara 70005 high current AC outlets which do not utilize the GFCI protection circuit or they may be powered by another discrete AudioQuest Niagara Series power product thus preventing the GFCI nuisance tripping As a final check inspect t

7. the reward will be system performance with the highest possible resolution and lowest possible noise To achieve that optimal performance we recommend the following guidelines For systems that utilize very few components bear in mind that it is advantageous to use the uppermost outlets in each bank as they have a closer proximity to the final stage noise dissipation circuits The same holds true for the High Current banks Again because banks 3 and 4 are 100 isolated from banks 5 and 6 placing a DAC and or universal player in one isolated group and a preamplifier and turntable in another would be an excellent way to start For systems that are much larger and require more outlets try starting with the most basic setup then adding one component at a time Try either of the two isolated bank groups to see which works best for you The bank that sounds best yielding the greatest resolution isthe best one for your system 10 Suggested AC Connections Powered Loud Flat Screen Speaker Pa o Monitor Line Level Pre Projector Engaged Monoblock Pream p position must be 8 amplifier Universal layer default setting me fin cer See page 10 MN o O 0 for use of Standby mode HIGH CURRENT LOW Z POWER CORRECTION TK i ULTRA LINEAR NOISE DISSIPATION SYSTEM DIELECTRIC BIASED SYMMETRICAL POWER ZT POWER CORRECTION 1 2 e 7 17 00 17 20 AMPS RMS MAXIMUM OUTPUT
