Trouble-Shooting Guide

At AudioQuest, we always appreciate hearing from you. However, if you have questions, problems, or

suspect that your Niagara 7000EU requires service, please start here.

There is no power to any of the AC outlets.

When the Niagara 7000EU's front-panel LED power indicator glows blue, the unit is operational. If the Power On

indicator is not lit, consider the following:

¡ Is the upper portion of the front-panel rocker switch fully flush with the chassis?

¡ Is the input AC cord fully inserted into the Niagara 7000EU's AC inlet?

¡ Is the input AC cord properly plugged into the wall AC service outlet?

¡ Is the wall's AC outlet functioning properly?

Plug into the outlet another component, product, or lamp to verify that power is present and that the electrical

panel's circuit breaker has not tripped. If there are only one or two AC outlets that have no output power, a

component may be malfunctioning. Verify the AC output with a known simple device such as a lamp.

There is no power to any of the AC outlets and the red front-panel

Extreme Voltage indicator is lit.

This indicates that either there is more than 270VAC (+/-3V) present on the wall's AC service outlet, or the Niagara

7000EU's protection circuit is mis-calibrated. The latter is quite rare. (This circuit is adjustable, but it's tested and

retested before it leaves the factory). Use an AC voltage meter to determine if your outlet has too much voltage

to be safe for operation, or if there is a wiring fault that is causing this to occur.

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.

There is no power to any of the Level-X Ultra-Linear Dielectric-Biased

Symmetrical Power outlets.

The front panel has two 3-amp circuit breaker reset buttons that are slightly inset from the edge of the panel. The

button to the left controls AC outlet bank 3, and the button to the right controls AC outlet bank 2. It would be

VERY unlikely that both circuit breakers would trip from too much RMS current draw per outlet group. However,

if one outlet group (banks 2) or the other group (banks 3) has no output, check to see if the breaker for that AC

outlet group has tripped. To reset the breaker: Using the back of a pencil or pen, press the appropriate circuit

breaker reset button into the chassis until it reaches its normal state—slightly loose, with little spring tension.

When resetting or testing the reset of one or both of the front-panel 3-amp XFMR-1 and XFMR-2 circuit breakers,

it is important that the AC outlet group is not connected to a component or product that is defective and has

shorted. To verify that the circuits are working, we recommend disconnecting all but one known properly

functioning product from the AC outlet group.

If after verifying that the circuits are operating (or, if after resetting the circuit breaker for one of the power

groups), you discover that one or multiple products activate the circuit breaker, check the current consumption

rating of that/those products. (Typically, this information can be found on the last page of the component's

owner's manual; it should be listed as the power consumption at 230VAC.)

The current specification will typically be in watts. Know that 3 amps at 230VAC equal 690 watts. (You will want to

be at least slightly under that number.) You may simply add wattage ratings to calculate your total consumption:

If you have four components into group one (bank 3 - outlets 9/10/11/12), the maximum capacity of all four

outlets combined is just under 690 watts or 3 amps. The same is true for group two (banks 2 - outlets 5/6/7/8).
