("switched"). Switched outlets can be powered on and off locally via the
front-panel "Switched" button, or remotely via another home theater
component. For example, you can use your preamplifier (preamp) as
a "remote trigger" so that when you turn it on, your AVU1500 will
automatically power on all the switched outlets; when you turn your
preamp off, the AVU1500 will power off all the switched outlets. It's much
easier to turn your preamp on and automatically trigger your amplifier
and subwoofer to power on (as well as any other device plugged into a
switched outlet), instead of having to turn on (and off) each and every
device one by one.
Pure Performance
Frequent electrical disturbances, both natural and man-made, degrade
the quality of power supplied to your home theater system. Ordinary
household AC power that is delivered to your home is also polluted with
"noise" from many sources within your home, including digital components
and household appliances. Also, noise can be created by components and
contaminate other connected equipment. All this degraded power quality
and noise can deteriorate the performance of your home theater system.
Your AVU1500's advanced Phase 4 PureFilter Circuitry is optimized to
remove electrical noise and provide clean and clear power to all of your
valuable digital, audio, video, and high-current equipment.
The multiphase PureFilter Circuitry also provides true isolation between
audio, video, digital, and high-current components. This isolation prevents
noise created by components that are already connected to your AVU1500
from contaminating other connected equipment.
Pure Protection
Your AVU1500 provides outstanding surge protection and power
conditioning. This protection not only saves your equipment, but also helps
extend the life of your equipment.
Most people don't realize that their components are subject to many
power disturbances everyday. Even small electrical surges and spikes
can damage your sensitive equipment over time. The AVU1500 has a
substantial 8000 joules of surge protection to protect your valuable home
theater system from these dangerous conditions.
As you may know, your AC power source is not the only threat to the
safety of your equipment. This is why the Belkin PureAV AVU1500 has
four sets of coaxial connections to protect your coaxial-cable lines, as well
as telephone jacks to protect Pay-Per-View lines and broadband Ethernet
jacks to protect data lines that stream digital content to your home
theater system.
The AVU1500's unique Automatic Voltage Regulation (AVR) technology
automatically provides clean, stable power by increasing low or decreasing
high voltage without the aid of the battery, keeping it within a safe range
of 110 to 120 volts. However, in the event input voltages reach dangerous
