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 connect-
ing 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.
Remote IR Carrier Output:
This output is similar in function to
the Remote IR Output, with the difference that this jack outputs the
full infrared signal as received by the AVR’s IR sensor or the Remote
IR Input, while the Remote IR Output jack outputs a “stripped” signal
that has no carrier frequency. The full signal may be required by some
components with IR inputs. It may also be required when you connect
external IR emitters or other devices to the AVR to pass IR signals to
other components.
Multiroom Audio Outputs:
Connect these jacks to an external
amplifier to power the speakers in the remote zone of a multiroom
system. When these jacks are used, it is possible to have a full 7.1-
channel system in the main listening room at the same time the
multiroom system is in use.
A-BUS Port:
Use a Category 5/5e cable to connect this port to
optional A-BUS equipment for multiroom operation. When the A-BUS
system is used, it is possible to have a full 7.1-channel system in the
main listening room at the same time the multiroom system is in use.
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 component video or HDMI inputs, you may take advantage of the
AVR 347’s transcoding capability, which transcodes composite and
S-video signals to component video and HDMI, 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 347’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 347 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.
