AVR
Types of Home Theater System Connections
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.
Network Connector
the Avr’s network connector allows you to enjoy Internet radio or content from other
dlnA-compatible devices that are connected to the same network. use a cat. 5 or
cat. 5e ethernet cable to connect the Avr’s rJ-45 connector to your home network.
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 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.
RS-232 Connector
your Avr’s rS-232 serial port may be connected to an external control system to allow
it 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 considerable technical knowledge and is best left to a professional custom
installer.

CAUTION: Before making any connections to the audio/video receiver, ensure
that the AVR’s AC cord is unplugged from the receiver and the AC outlet.
Making connections with the receiver plugged in and turned on could damage
the speakers.
Connect Your Speakers
After you have placed your loudspeakers in the room as explained in Place Your Speakers,
on page 13, connect each speaker to its color-coded terminal on the Avr as explained
in Speaker Connections, on page 14. connect the speakers as shown in the illustration.

Connect Your Subwoofer
use a single rcA audio cable to connect the Avr’s Subwoofer connector to your subwoofer
as explained in Subwoofer Connections, on page 14. note: the Avr 3700 and Avr 370
provide connections for two subwoofers. See Manual Speaker Setup: Number of Speakers,
on page xx, for information about activating the two subwoofer outputs. consult your
subwoofer’s user manual for specific information about making connections to it.

If your tv has an hdmI connector: use an hdmI cable (not included) to connect it to the
Avr’s hdmI monitor out connector. the Avr 3700 and Avr 370 provide hdmI connections
for two tvs. you do not need to make any other connections to your tv from the receiver
or from any of your video source components.

video connector.

Making Connections
Connect Your Audio and Video Source Devices
Source devices are components where a playback signal originates, e.g. a Blu-ray
Disc™ or DVD player; a cable, satellite or HDTV tuner; etc. Your AVR has several different
types of input connectors for your audio and video source devices: HDMI, component
video, composite video, optical digital audio, coaxial digital audio and analog audio.
The connectors are not labeled for specific types of source devices; they are labeled
numerically, so you can connect your devices according to your individual system’s
make-up.
Your AVR’s various source buttons have default assignments to different input connectors
Your AVR’s various source buttons have default assignments to different input connectors
(listed in the “Default Connector(s)” column of the table below). For ease of setup, you
should connect each source device to the connector where the corresponding default
source button is assigned (e.g., connect your Blu-ray Disc player to HDMI 1).
However, you can connect your source devices as you wish and re-assign any of the
input connections to any of the Source Buttons listed in the table according to where you
actually connect each of your source devices.
As you connect your various source devices, fill out the “Connected Component” column
As you connect your various source devices, fill out the “Connected Component” column
in the table – it will make it easier for you to assign the various source buttons after
you have completed making all of the connections. (You will make any changes to the
source-button assignments and fill in the “Assigned Connector(s)” column later in the
setup process.)
Note: You cannot assign connectors to the Network, Radio and USB source buttons.

If any of your source devices have hdmI connectors, using them will provide the best
possible video and audio performance quality. Since the hdmI cable carries both digital
video and digital audio signals, you do not have to make any additional audio connections
for devices you connect via an hdmI cable.
