INITIAL SETUP

The Initial Setup section requires that you complete all of the steps
in the Installation section that apply to your receiver. You should have
connected all of your loudspeakers and a video display, as well as your
source devices. You should be able to turn on the receiver and view
a blue screen on your video display. If necessary, reread the Installation
Section before continuing.

Configure the AVR 347 Using EzSet/EQ

One of the most important and perhaps often overlooked aspects of
setting up a home theater system is to calibrate the receiver to match
the loudspeakers, which enables the AVR to perform at its best.

Until recently, most receivers required the user to perform the calibration
and configuration manually, a somewhat tedious process that called for
a good ear or the purchase of an SPL (sound-pressure level) meter.
Although you may configure the AVR 347 manually, as described in
the Advanced Features section, we recommend that most users take
advantage of our signature EzSet/EQ system.

Before beginning, eliminate extraneous background noise that might
affect the results, such as noisy air conditioning. Try to avoid making
any loud noises while running EzSet/EQ.

IMPORTANT SAFETY NOTE:

During the EzSet/EQ procedure,

a series of very loud test tones will be played through all of the
speakers. Avoid sitting or standing close to any one speaker
during the procedure. If you are particularly sensitive to loud
noises, you may wish to leave the room and have someone
else run EzSet/EQ.

Step One –

Place the included EzSet/EQ microphone in the listening

position, or in the center of the room, at about the same height as the
listeners’ ears. The microphone features a threaded insert on the bottom
so that it can be mounted on a camera tripod for stability. An extender
rod is also included.

Step Two –

Plug the EzSet/EQ microphone into the Headphone

Jack/EzSet Microphone Input Jack on the front of the receiver.
See Figure 51.

Step Three –

Make sure that the AVR 347 and the video display are

turned on. Press the OSD Button to display the Menu System. See
Figure 48. Use the

⁄

Buttons to move the cursor to the Speaker

Setup tab, and then press the Set Button to select the Speaker Setup
menu. See Figure 52.

Select the “Auto Configuration” setting, and the screen shown in Figure
53 will appear to direct you to plug the EzSet/EQ microphone into the
Headphone Jack.

Step Four –

After you select “Continue”, the screen shown in Figure 54

will appear. Although the AVR 347 may be used with up to eight speakers,
you may have elected not to install surround back speakers at this time,
or you may have decided to use the surround back speaker channels to
power speakers in the remote room of a multiroom system. This screen
directs you to program EzSet/EQ for a 5.1- or 7.1-channel configura-
tion. Select the setting that reflects the number of speakers installed in
your system, and EzSet/EQ will do the rest automatically!

NOTE:

If you are using fewer than five main speakers in your

system, then it will not be possible to configure your speakers
using EzSet/EQ, and you will need to select Manual Configuration
as described in the Advanced Functions section. If you have
selected a 6.1-channel configuration, using only a single surround
back speaker, it is possible to use a combination of EzSet/EQ
automatic configuration for 5.1 speakers, connect the single
