CONNECTIONS
Composite video is the basic connection most commonly available.
The jack is usually color-coded yellow, and looks like an analog
audio jack. Do not plug a composite video cable into an analog or
coaxial digital audio jack, or vice versa. Both the chrominance
(color) and luminance (intensity) components of the video signal
are transmitted using a single cable. See Figure 10.
Figure 10 – Composite Video
S-video, or “separate” video, transmits the chrominance and lumi-
nance components using separate wires contained within a single
cable. The plug on an S-video cable contains four metal pins, plus a
plastic guide pin. Align the plug correctly when you insert it into the
jack. See Figure 11.
Figure 11 – S-Video
Component video separates the video signal into three compo-
nents – one luminance (“Y”) and two sub-sampled color signals
(“Pb” and “Pr”) – that are transmitted using three separate cables.
See Figure 12.

If it’s available on your video display, an HDMI connection is recom-
mended as the best quality connection, followed by component
video, S-video and then composite video.
NOTES:
• Copy-protected sources are not available at the Component
Video Monitor Outputs.
• Standard and high-definition analog video signals may
be upscaled to 1080i resolution for the Component Video
Monitor Outputs. For improved video performance, consider
upgrading to an HDMI-capable video display with 1080p
resolution.
ANTENNAS
The AVR 7550HD uses separate terminals for the included FM and
AM antennas.
The FM antenna uses a 75-ohm F-connector. See Figure 13.
Figure 13 – FM Antenna
The AM loop antenna needs to be assembled. Connect the two leads
to the spring terminals on the receiver. The AM antenna leads have
no polarity, and you may connect them to either terminal. See
Figure 14.

To enjoy XM satellite radio, purchase an XM Ready antenna module
and a subscription to the XM service. The XM Mini Tuner and Home
Dock Bundle, available at www.xmradio.com, is recommended.
The older Connect-and-Play module is also compatible with the
AVR 7550HD, but it may no longer be available. Although you may
use a module with standard audio connections, labeled for “car
and home use,” you will not be able to enjoy the AVR 7550HD’s
ease of control.
RS-232 SERIAL PORT
The RS-232 serial port may be connected to an external computer
or control device to allow the external device to transmit control
commands to the AVR. The port is bidirectional, so that the AVR can
transmit status updates to the control device. Connecting and using
the RS-232 port requires technical knowledge, and is best left to
a professional custom installer.
