Trouble-Shooting Guide
At AudioQuest, we always appreciate hearing from you. However, if you have questions, problems, or
suspect that your Niagara 3000 requires service, please start here.
There is no power to any of the AC outlets.
When the Niagara 3000'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 3000'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 140VAC (+/-3V) present on the wall's AC service outlet, or the Niagara
3000'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, and it's glued into place, so shipping will not affect it.) 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 (90VAC to 137 VAC), the Niagara 3000's protection
circuit will automatically switch to operational mode and the blue power indicator will light.
The main power rocker switch/circuit breaker tripped to the lower (off) position
while the system was playing.
You may have exceeded the maximum current capacity of the Niagara 3000. This should be rare, but it may be
possible. Typical power amplifiers draw about one-third of their maximum current consumption at 120VAC, as
listed in the product's specifications (typically found in their owner's manual). This is further complicated by the
fact that the power consumption to all AC outlets (1 through 7), is a cumulative draw on the maximum current
capacity of 15 amps that will trip this power switch/magnetic circuit breaker.
The Transient Power Correction Circuit may also contribute to the overall draw seen by the circuit breaker. Still,
it should be rare that the total capacity is exceeded, but, given that some televisions, projectors, and power
amplifiers can draw substantial current, it is certainly not impossible. If this is the case, an additional Niagara 3000,
and a discrete 15- to 20-amp AC service on the same phase of the electrical panel, will be required for some or all
of the power amplifiers.
My power amplifiers sound muddy, compressed, or weak.
The Transient Power Correction Circuit may not be operating. Be sure that all power amplifiers, powered receivers,
powered loudspeakers, and/or powered subwoofers are plugged into the High-Current/Power Correction AC
outlets. If any of these are plugged into the Linear Power outlets, the connected power amplifier(s) will be current
compressed, as the impedance is too high for any power amplifier.
