Types of Home Theater System
Connections, continued
Digital Audio Connections – Optical
optical digital audio connectors are normally covered by a shutter to protect them from
dust. the shutter opens as the cable is inserted. optical input connectors are color-coded
using a black shutter.
Analog Audio Connections
two-channel analog connections require a stereo audio cable, with one connector for
the left channel (white) and one for the right channel (red). these two connectors are
attached to each other.
for source devices that have both digital and analog audio outputs, you may make both
connections.
Video Connections
many source devices output both audio and video signals (e.g., blu-ray disc, dVd
player, cable television box, hdtV tuner, satellite box, Vcr, dVr). In addition to an audio
connection as described above, make a video connection for each of these source
devices. make only one type of video connection for each device.
Digital Video Connections
If you have already connected a source device to one of the AVr’s hdmI input connectors,
you have automatically made a video connection for that device, since the hdmI cable
carries both digital audio and digital video signals.
Analog Video Connections – Composite Video
composite video is the basic connection most commonly available. both the chrominance
(color) and the luminance (intensity) components of the video signal are transmitted
using a single cable. the jack is usually color-coded yellow and looks like an analog
audio jack. do not connect a composite video jack to an analog audio or coaxial digital
audio jack, or vice versa.
Radio Connections
your AVr uses separate terminals for the included fm and Am antennas. the fm antenna
uses a 75-ohm f-connector.
the Am antenna connector uses spring-clip terminals. After assembling the antenna as
shown below, press the levers to open the connectors, insert the bare wires into the
openings, and release the levers to secure the wires. The antenna wires are not polarized,
so you can insert either wire into either connector.
USB Port
the AVr can play audio files from an Apple ioS
®
device connected to the uSb port,
and allows you to control the ioS device via the AVr remote control. the AVr can also
play mp3 and wmA audio files from a uSb device inserted into the uSb port. Insert the
connector or device into the uSb port oriented so it fits all the way into the port. you may
insert or remove the connector or device at any time – there is no installation or ejection
procedure.
the uSb port on your AVr is also used to perform firmware upgrades. If an upgrade for
the AVr’s operating system is released in the future, you will be able to download it to the
AVr using this port. complete instructions will be provided at that time.
IMPORTANT: Do not connect a PC or other USB host/controller to the AVR’s USB
port, or you may damage both the AVR and the other device. HDD is not supported.
