THX Ultra2™

Before any home theater component can be THX Ultra2 certified,
it must incorporate all the features above and also pass a rigorous
series of quality and performance tests. Only then can a product
feature the THX Ultra2 logo, which is your guarantee that the Home
Theater products you purchase will give you superb performance for
many years to come. THX Ultra2 requirements cover every aspect
of the product including power amplifier performance, pre-amplifier
performance and operation, as well as hundreds of other parameters
in both the digital and analog domain.
In addition to improvements to the power amplifier with respect
to previous THX Ultra standards, three surround modes have been
added: the THX Ultra2 Cinema mode, THX Music Mode and THX
Games Mode.

b “THX” and “Ultra2” are trademarks of THX Ltd. THX may be

registered in some jurisdictions. All rights reserved.

b In the NORMAL connection and Bi-AMP connection operation

mode, POA-A1HDCI has acquired THX certification. To play back
data in a manner that complies with the THX standard, use the
NORMAL connection or Bi-AMP connection mode.

Getting Started

Thank you for purchasing this DENON product. To ensure proper
operation, please read this owner’s manual carefully before using the
product.
After reading them, be sure to keep them for future reference.

Cautions on Handling

• Before turning the power switch on

Check once again that all connections are correct and that there are

no problems with the connection cables.

•

Power is supplied to some of the circuitry even when the unit is
set to the standby mode. When traveling or leaving home for long
periods of time, be sure to unplug the power cord from the power
outlet.

• About condensation

If there is a major difference in temperature between the inside of

the unit and the surroundings, condensation (dew) may form on
the operating parts inside the unit, causing the unit not to operate
properly.

If this happens, let the unit sit for an hour or two with the power

turned off and wait until there is little difference in temperature
before using the unit.

• Cautions on using mobile phones

Using a mobile phone near this unit may result in noise. If so, move

the mobile phone away from this unit when it is in use.

• Moving the unit

Turn off the power and unplug the power cord from the power

outlet.

Next, disconnect the connection cables to other system units before

moving the unit.

•

Note that the illustrations in these instructions may differ from the
actual unit for explanation purposes.
