REAR-PANEL CONNECTIONS

AM and FM Antenna Terminals:

Connect the included AM and

FM antennas to their respective terminals for radio reception.

XM Antenna Jack:

Plug in an XM antenna module here. The XM

antenna module is purchased separately, and should specify that it is
for home use with an XM Ready

product. You will need to subscribe to

the XM service, which is available separately, and activate the service for
your antenna module. (XM service is not available in Alaska and Hawaii.)

Front, Center and Surround Speaker Outputs:

Use two-

conductor speaker wire to connect each set of terminals to the correct
speaker. Remember to observe the correct polarity (positive and negative
connections). Always connect the positive lead to the colored terminal
on the receiver and the red terminal on the speaker. Connect the negative
lead to the black terminal on both the receiver and the speaker. See the
Connections section for more information on connecting your speakers.

Surround Back/Multiroom Speaker Outputs:

These speaker

outputs may be used either for the surround back channels in a 7.l-
channel home theater, or they may be reassigned to a remote room for
use with a multiroom system. When these outputs are reassigned for
multiroom operation, only a 5.1-channel configuration will be available in
the main listening room. Use the on-screen menu system to configure
these channels as desired.

As with the other speaker outputs, remember to observe proper polarity
by connecting the positive and negative output terminals to the corre-
sponding terminals on each speaker.

Subwoofer Output:

If you have a powered subwoofer with a line-

level input, connect it to this jack.

Preamp Outputs:

Connect these jacks to an external amplifier if

more power is desired.

Surround Back/Multiroom Preamp Outputs:

These outputs

may be used with an external amplifier either to power the surround
back channels, or to power the speakers in the remote zone of a multi-
channel system. Use the on-screen menu system to configure these
channels as desired.

Remote Infrared (IR) Input and Output:

When the remote IR

receiver on the front panel is blocked, such as when the AVR is placed
inside a cabinet, connect an optional IR receiver to the Remote IR Input
jack for use with the remote control. The Remote IR Output may be
connected to the Remote IR Input of a compatible source device (or
other product) to enable remote control through the AVR. This is particu-
larly useful in multiroom applications, when you wish to control the
source device from the remote room (when used with the Multiroom IR
Input). When several source devices are used, connect them in “daisy
chain” fashion.

Multiroom Infrared (IR) Input:

Connect a remote IR receiver

located in the remote zone of a multiroom system to this jack to control
the AVR and any source devices connected to the Remote IR Output
from the remote zone.

Video 1, Video 2, Video 3 and DVD Audio/Video Inputs:

These jacks may be used to connect your video-capable source

components (e.g., VCR, DVD player, cable TV box) to the receiver.
Remember to use only one type of video connection for each source.
See the Connections section for more information on audio and video
connection options for each source component.

Video 1 Audio/Video Outputs:

These jacks may be used to

connect your VCR or another recorder.

Composite and S-Video Monitor Outputs:

If any of your

sources use composite or S-video connections, you may need to
connect one or both of these monitor outputs to the corresponding
inputs on your television or video display in order to view the sources
and to view the on-screen displays. If your video display is equipped
with HDMI or component video inputs, you may take advantage of the
AVR 247’s transcoding capability, which transcodes composite and
S-video signals to HDMI and component video, allowing for only a
single video connection from the AVR to the video display.

HDMI Inputs and Output:

HDMI (High-Definition Multimedia

Interface) is a newer type of connection for transmitting digital audio and
video signals between devices. With the AVR 247’s powerful processor,
you may connect up to two HDMI-equipped source devices to the HDMI
inputs using a single-cable connection, while benefiting from superior
digital audio and video performance. However, if your video display is
not HDMI-compatible, you will need to connect the device to one of the
other source inputs, selecting a coaxial or optical digital audio input and
analog video input. See the Connections and Installation sections for
more information.

If your video display has an HDMI input, but some of your sources
have only analog video outputs, you may still rely on just the HDMI video
connection to your display; the AVR 247 will automatically transcode
analog video signals up to 720p to the HDMI format. High-resolution
analog 1080i or higher signals are not available at the HDMI Output.

The AVR 247 is Simplay HD-verified for compatibility via the HDMI
connection with other Simplay HD-verified products.

CD and Tape Audio Inputs:

These jacks may be used to connect

audio-only source components (e.g., CD player, tape deck). Do not
connect a turntable to these jacks without a phono preamp.

Tape Outputs:

These jacks may be used to connect a CDR or

another audio-only recorder.

Coaxial and Optical Digital Audio Inputs:

If a source has

a compatible digital audio output, connect it to one of these jacks
for improved audio performance. Use only one type of digital audio
connection for each source.

Coaxial and Optical Digital Audio Outputs:

If a source is

also an audio recorder, you may connect a compatible digital audio
output to the recorder’s input for improved recording quality.

The Bridge/DMP Input:

Connect the optional Harman Kardon

to this input for use with your iPod (not included). Make

sure the receiver is turned off (in Standby mode) when connecting
The Bridge.
