    All sincere attempts to solve this problem must be applauded since once the audio/video signal is gone, it’s gone forever... For AudioQuest, honoring the source is never a matter of simply using premium “audiophile-grade parts” or relying on a proprietary technology—common approaches used within the audiophile market. For years, we have all been witness to the same, seemingly endless audiophile debates: Valves versus transistors.
  • Page 4 A great system is built from a solid foundation, and that foundation starts with power. With an AudioQuest Niagara 7000EU, you’ll experience for the first time the clarity, dimensionality, frequency extension, dynamic contrast, and grip your system has always been capable of delivering—if only the power had been right!

  • Page 5: Installation

    ¡ The Niagara 7000EU has been dropped and sustained considerable physical damage. If sending the Niagara 7000EU to AudioQuest for servicing (or shipping it for any reason), please use the factory- approved packaging materials. If you have lost any of these (double carton, two foam inserts, one poly bag), please contact AudioQuest for replacements.

  • Page 6: Placement

    Torx flathead screws from the front portion of both the left and right sides of the cover assembly. Next, mount the rack ears flush against the back of the Niagara 7000EU’s front panel. Finally, secure the rack ears into place by installing the rack-mount kit’s Phillips pan head SEMS screws.

  • Page 7: High Current/Low-Z Power Banks

    This is key to the Niagara 7000EU’s discrete AC power banks, in that not every circuit is treated the same, but rather isolated bank by bank and optimized for best performance.

    (akin to a power amplifier left in full operational mode). This is actually far from the truth. If the Niagara 7000EU was consuming that much current (or even 20% of that level), it would need to dissipate the energy loss in heat. It would be quite warm (even hot) to the touch, just like most power amplifiers while in operation.

  • Page 11: Ground Fault Circuit Interrupter (Gfci) "Test" Button/Momentary Switch

    AC cord that supplies power to the Niagara 7000EU. This is because the wiring and the circuit breaker that supply power to Niagara 7000EU simply look at RMS current and do not distinguish between reactive loads, resistive loads, or inductive loads, but your utility does.

    It will improve gradually, in small increments, over a period of approximately two weeks. While leaving the Niagara 7000EU turned on during this period will aid the process, it is also perfectly acceptable to turn the unit off; doing so will simply increase the time it takes to reach final “break-in.”...

    Standby setting. (This is dependent on a reactive vector load. For more info, see “Operation and Continuous Use: Rear-Panel Power Correction Switch | Niagara 7000EU Current Draw.”) Dimensions: 445mm W x 149mm H (133mm H without feet) x 437mm D (3-RU...

  • Page 14: Trouble-Shooting Guide

    Once the power is brought into a safe range for operation (190VAC to 270 VAC), the Niagara 7000EU’s protection circuit will automatically switch to operational mode and the blue power indicator will light.
  • Page 15 AudioQuest Niagara Series power product, thus preventing the GFCI nuisance tripping. As a final check, inspect the GFCI test button on the left side of the Niagara 7000EU’s front panel. It is a momentary switch and it will not latch; by pressing it lightly into the chassis, it will activate the GFCI protection circuit and trip the main power switch/magnetic circuit breaker.
  • Page 16 If the hum no longer persists under these conditions (which is likely), try reconnecting each additional component into the Niagara 7000EU one at a time. Once you find the component that creates the hum, you can possibly achieve increased isolation by connecting it to a different Ultra-Linear/Symmetrical Power outlet group. This can typically help, as well as increase overall system performance by decreasing system noise.
  • Page 17 The force required to damage the Niagara 7000EU via a power surge would melt the panel and burn the building (in which case, the Niagara 7000EU is the least of your worries).
  • Page 18 Niagara 7000EU’s AC isolation transformers are like the proverbial “canary in a coal mine.” In all likelihood, the Niagara 7000EU has not developed a problem. (If you remove all of the AC output cords and listen for the slight buzzing sounds, you will likely find that they are gone.) However, it is possible that otherwise state-of-the-art components are causing the problem.
