AVR

Types of Home Theater System Connections

There are different types of audio and video connections used to connect the AVR to your

speakers, your TV or video display, and your source devices. The Consumer Electronics

Association has established the CEA

color-coding standard.

Analog Audio Connection Color

Front Left/Right White/Red

Center Green

Surround Left/Right Blue/Gray

Subwoofer Purple

Digital Audio Connection Color

Coaxial Orange

Optical Input Black

Analog Video Connection Color

Composite Video Yellow

Speaker Connections

Speaker cables carry an ampliﬁed signal from the AVR’s speaker terminals to each

loudspeaker. They contain two wire conductors, or leads, that are differentiated in some

way, such as with colors or stripes.

The differentiation helps you maintain proper polarity, without which your system’s low-

frequency performance can suffer. Each speaker is connected to the AVR’s speaker-

output terminals using two wires, one positive (+) and one negative (–). Always connect

the positive terminal on the speaker, which is usually colored red, to the positive terminal

on the receiver, which is colored as indicated in the Connection Color Guide Table, above.

The negative terminals on the speakers and the AVR are black.

Your AVR uses binding-post speaker terminals for the Front Left/Right speakers that

can accept bare-wire cables or banana plugs in addition to spring-clip terminals for

the Center and Surround speakers that only accept bare-wire cables. For the spring-

clip terminals, press the levers to open the connectors, insert the bare wires into the

openings, and release the levers to secure the wires. Bare-wire cables are installed as

shown below:

1. Unscrew Cap 3. Tighten Cap2. Insert Bare Wire

Banana plugs are inserted into the hole in the middle of the terminal cap, as shown

below:

A. Tighten Cap

B. Insert Banana Connector into Hole in Cap

Always connect the colored (+) terminal on the AVR to the (+) terminal on the speaker

(usually red), and the black (–) terminal on the AVR to the (–) terminal on the speaker

(usually black).

IMPORTANT: Make sure the ( + ) and ( – ) bare wires do not touch each other or

the other terminal. Touching wires can cause a short circuit that can damage your

receiver or ampliﬁer.

Subwoofer Connections

The subwoofer is a speaker dedicated to reproducing only the low (bass) frequencies,

which require more power. To obtain the best results, most speaker manufacturers offer

powered subwoofers that contain their own ampliﬁers. Use a single RCA audio cable to

make a line-level (non-ampliﬁed) connection from the AVR’s Subwoofer connector to a

corresponding input jack on the subwoofer.

Although the AVR’s purple subwoofer output looks similar to a full-range analog audio

jack, it is ﬁltered so that only the low frequencies pass through it. Don’t connect this

output to any device other than a subwoofer.

Source Device Connections

Audio and video signals originate in source devices (components where a playback

signal originates) such as your Blu-ray Disc or DVD player, CD player, DVR (digital video

recorder) or other recorder, tape deck, game console, cable or satellite television tuner,

an iPod or iPhone (connected to the AVR’s USB port) or an MP3 player. The AVR’s FM/AM

tuner also counts as a source, even though no external connections are needed other

than the FM and AM antennas. Separate connections are required for the audio and

video portions of the source device’s signal, except for digital HDMI connections. The

types of connections you use will depend upon the capabilities of the source device and

of your TV or video display.

Digital Audio Connections – HDMI

There are two types of audio connections – digital and analog. Digital audio signals are

required for listening to sources encoded with digital surround modes, such as Dolby

Digital and DTS, or for uncompressed PCM digital audio. Your AVR has three types of

digital audio connections: HDMI, coaxial and optical. Do not use more than one type of

digital audio connection for each source device. However, it’s okay to make both analog

and digital audio connections to the same source.

Your AVR is equipped with rear-panel HDMI input and output connectors. HDMI technology

enables high-deﬁnition digital audio and video information to be carried using a single

cable, delivering the highest quality picture and sound. If your TV or video display device

has an HDMI input connector, make a single HDMI connection from each HDMI-enabled

source device to the AVR. Usually, a separate digital audio connection is not required.

The AVR’s HDMI output connection contains an Audio Return Channel (ARC) that carries

a digital audio signal from your TV or video display back to the AVR. It allows you to listen

to HDMI devices that are connected directly to your TV (such as an Internet connection)

without making an additional connection from the device to the AVR. The ARC signal

is active when the TV source is selected. See System Settings, on page 29, for more

information.

The HDMI connector is shaped for easy plug-in (see illustration, below), and HDMI cable

runs are limited to about 10 feet (3m). If your video display has a DVI input and is

HDCP-compliant, use an HDMI-to-DVI adapter (not included), and make a separate audio

connection.
