INSTALLATION
You are now ready to connect the various components to the receiver.
Before beginning, turn off all components, including the AVR 254,
and
unplug their power cords.
Don’t plug in any of the power cords
until you have finished making all of your connections.
Remember that the receiver generates heat while it is on. Select a
location that leaves several inches of space on all sides of the receiver.
Avoid completely enclosing the receiver inside an unventilated cabinet.
It is preferable to place components on separate shelves rather than
stacking them directly on top of the receiver. Some surface finishes are
delicate. Try to select a location with a sturdy surface finish.
Step One – Connect the Speakers
If you have not yet done so, place your speakers in the listening room,
as described in the Speaker Placement section above.
Connect the center, front left, front right, surround left, surround
right, surround back left and surround back right loudspeakers to the
corresponding speaker terminals on the AVR 254. See Figure 17.
Maintain the proper polarity by always connecting the positive and
negative terminals on each speaker to the positive and negative
terminals on the receiver. Use the Connection Color Guide on page 18
as a reference.
Figure 17 – Speaker Connections
NOTE: If you only have one surround back speaker, wait until after
you have run the EzSet/EQ process in the Initial Setup section
before connecting it to the Surround Back Left speaker outputs.
Step Two – Connect the Subwoofer
Connect the Subwoofer Output on the AVR 254 to the line-level input
on your subwoofer. See Figure 18. Consult the manufacturer’s guide for
the subwoofer for additional information.
When the system has two subwoofers for a 7.2-channel system, use a
Y-Adapter (not included) with one male RCA plug and two female RCA
jacks. Connect the male plug to the Subwoofer Output, and connect
each female jack to a cable that is then plugged into the line-level input
on each subwoofer.

Step Three – Connect the Antennas
Connect the FM and AM antennas to their terminals. If you have
purchased an XM antenna module designed for connection to an
XM Ready device, connect it now. To enjoy XM Radio, remember to
purchase a subscription and activate your antenna module. More
information is available at www.xmradio.com. See Figure 19.

Step Four – Connect the Source Components
A source is a device where the audio and video signals originate. Some
sources, such as CD players, only offer audio, while sources used for
watching movies or broadcast-television programming deliver a video
signal as well.
Referring to the photograph of the AVR 254 remote control on page 15,
there is a section of 7 buttons near the top of the remote designated
“Source Selectors”: Cable/Sat, DVD, Media Server, Radio, TV, Game
and AUX. Each of these buttons corresponds to a “source input”. The
AVR 254’s flexible design allows you to use almost any combination
of audio and video connections for each source device. The goal of
Step Four of the Installation is to match up each of your source devices,
e.g., DVD player and cable television box, with the correct connectors
on the AVR 254.
You may connect a source device to any appropriate input connectors.
Note which audio and video inputs are used for each device in Table A5
in the appendix. Table A2 indicates the default input-connection assign-
ments, any of which may be changed to match the actual connections
in your system.
The precise connections to be made depend on the capabilities of the
source device and your video display (TV). Select the best audio and
video connections for each source. The types of connections are listed
in order of preference:
