Trouble-Shooting Guide
At AudioQuest, we always appreciate hearing from you. However, if you have questions, problems, or
suspect that your PowerQuest 505 EU requires service, please start here.
There is no power to any of the AC outlets.
When the PowerQuest 505 EU’s front-panel LED power indicator glows green, the unit is operational. If the
Protection On indicator is not lit, consider the following:
• Is the upper portion of the front-panel rocker switch fully ush with the chassis?
• Is the input AC cord fully inserted into the PowerQuest 505 EU’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 Overvoltage
Protection indicator is lit.
This indicates that either there is more than 270VAC (+/-5V) present on the wall’s AC service outlet, or the
PowerQuest 505 EU’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 aect
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 (180VAC to 265 VAC), the PowerQuest 505 EU’s
protection circuit will automatically switch to operational mode and the green power indicator will light.
The rear panel circuit breaker tripped (the button is extended outward) while
the system was playing.
You may have exceeded the maximum current capacity of the PowerQuest 505 EU. This should be rare, but
it may be possible. Typical power ampliers draw about one-third of their maximum current consumption at
220-240VAC, as listed in the product’s specications (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 10 amps that will trip the circuit breaker.
My home or grounds were hit by lightning. The PowerQuest 505 EU seems to be
functioning properly. Should it be sent in for inspection or service?
If you see or smell smoke coming from the unit, it needs service. Otherwise, if it functions after such an
event (which is very likely), there is nothing that would be compromised or damaged. If it fails after such an
event, it will fail totally. However, it’s unlikely that this would occur. The circuit is designed to easily handle
any voltage or current surge that could possibly make it past an electrical panel. The force required to
damage the PowerQuest 505 EU via a power surge would melt the panel and burn the building (in which
case, the PowerQuest 505 EU is the least of your worries).
How do I clean the chassis?
The PowerQuest 505 EU’s black textured polymer and anodized front panel can be cleaned with AudioQuest
CleanScreen, or a modest misting of household window cleaners. Please use soft cotton or wool toweling to
remove the liquid from the metal and painted surface. Never use alcohol or solvent-based cleaners. They can
damage the surfaces, paint, and silk-screening material.
