Types of Home Theater System Connections

AVR

Digital Audio Connections – Coaxial

Coaxial digital audio jacks are usually color-coded in orange. Although they look like 
standard RCA-type analog jacks, you should not connect coaxial digital audio outputs to 
analog inputs or vice versa.

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, while optical outputs use a gray 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. If you are going to be setting up a multizone system, remember that Zone 
2 is an audio-only zone (the AVR does not have a Zone 2 video output). Therefore, make 
analog connections for any audio source devices (such as a CD changer) that you will 
want available for listening in Zone 2 at all times. 

The analog connections also feed the analog record outputs. You may record materials 
from Blu-ray Disc recordings, DVDs or other copy-protected sources using only analog 
connections. Remember to comply with all copyright laws if you choose to make a copy 
for your own personal use.

The Bridge IIIP Connection

Your AVR includes a proprietary, dedicated connector for an optional The Bridge IIIP 
docking station for the iPod or iPhone. The Bridge IIIP outputs analog audio to the AVR 
and is available as a source to Zone 2 in a multizone system.

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

Your AVR uses two types of analog video connections: composite video and component 
video.

Composite video is the basic connection most commonly available. Both the chrominance 
(color) and 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.

Analog Video Connections – Component Video

Component video separates the video signal into three components – one luminance 
(“Y”) and two sub-sampled color signals (“Pb” and “Pr”) – that are transmitted using 
three separate cables that are color-coded green (Y), blue (Pb) and red (Pr). Component 
video cables that join three separate green, blue and red connectors into a single cable 
are sold separately.

If your TV or video display has an HDMI connection, we recommend it as the best quality 
connection. Your AVR converts composite and component analog video input signals to 
the HDMI format, upscaling them to high-definition 1080p resolution.
