The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important installation, operation, and service instructions in this manual.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the
presence of uninsulated dangerous voltages within the enclosure that may be of sufficient magnitude to
constitute a risk of electrical shock to the user.
Please read this manual thoroughly before attempting to install, configure, or operate the
XPA-2 power amplifier. After successful installation and configuration of the XPA-2,
be sure to retain this manual in a safe place for future reference.
Safety is a key component to a long lasting and trouble free installation. Please read and follow all
instructions and heed all warnings on the XPA-2 and in this manual. The vast majority of the subsequent
safety precautions are common sense. If you are not comfortable with the installation of audio/video
entertainment equipment, you should seek the services of a qualified installation professional or call us for
help.

Do not install the XPA-2 near or above any heat sources such as radiators, heating vents, or other apparatus’
that produce heat. Do not block any ventilation openings or heat sinks. Avoid installing the unit directly
above other heat-producing equipment unless sufficient ventilation or forced-air cooling is provided.
Do not install the XPA-2 in locations without proper ventilation. The XPA-2 should not be operated on a bed,
sofa, rug, or similar surface that may block vents. The unit should not be installed in an enclosed location
such as a bookcase, cabinet, or closed equipment rack unless sufficient forced-air ventilation is provided.
Always install your XPA-2 according to the manufacturer’s instructions and only use attachments or
accessories specified by the manufacturer.
Do not install the XPA-2 on any stand, shelf, or other piece of furniture that is unable to support its weight. If
a cart is used to move the unit, use caution to avoid injury from tip-over.
Connect the XPA-2 only to power sources of the correct voltage (as shown in this manual and on the XPA-2
unit).
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful
where the power cable enters the power outlet and the unit.
Only connect the XPA-2 to an electrical outlet or extension cord of appropriate type and rating.
DO NOT defeat the safety purpose of a grounding or polarized plug by removing ground pins or using
unsafe adapters. A polarized plug has two blades - one wider than the other. A grounding plug has a
third ground prong in addition to the two main conductors. The wide blade or third groundling prong is
provided for your safety. If the provided plug does not fit your outlet, consult an electrician to replace your
obsolete outlet. If you replace the power cord, only use one of similar type and equal or greater current
rating.
The power cable for the XPA-2 should be unplugged from the outlet during severe electrical storms, or
when unused for a long period of time.
