INITIAL SETUP
Figure 50 – EzSet/EQ: Warning to Plug in Microphone
NOTE: As shown in Figures 48, 49, and 51– 54, while EzSet/EQ
is in progress a Cancel setting is available or even highlighted. You
may interrupt EzSet/EQ at any time by selecting the Cancel setting
and pressing the Set Button.
What EzSet/EQ Does
EzSet/EQ will send test signals to the various speakers and perform
the measurements described in this section, adjusting the AVR 247’s
settings to match EzSet/EQ’s internal references.
Set Master Volume Level: EzSet/EQ sends test tones to the front
speakers and adjusts the system’s volume level to enable it to take the
remaining measurements correctly. EzSet/EQ uses the left front speaker
to set the master volume level, and then it proceeds directly to measuring
the speaker output levels.
Speaker Level: During this test, EzSet/EQ ensures that all speakers
sound equally loud at the listening position. During a surround sound
presentation it is common for the surround channels to sound less
prominent, or not to be used at all at times. By setting the baseline
channel levels correctly, the AVR serves as a blank canvas for the
movie director to create special effects.
A screen similar to the one shown in Figure 51 will appear, with the
speaker position changing as EzSet/EQ measures the levels for each
speaker. You may occasionally hear EzSet/EQ send a tone back to the
front left speaker. This enables EzSet/EQ to compare the level of the
speaker being measured to the reference level it set for the front left
speaker.
Figure 51 – EzSet/EQ: Speaker Level Test
If at any time the test tone is not heard from the speaker indicated on
screen, press the Set Button to stop EzSet/EQ. Turn off the AVR using
the Master Power Switch and check your speaker connections. Make
sure all wires are connected to the correct speakers and Speaker
Outputs on the AVR, and that you have observed the correct polarity
(+ terminals connected to + terminals, and – terminals connected to
– terminals).
NOTE: EzSet/EQ can only detect the presence of a speaker,
not its location within the room. If your speakers are not placed
reasonably close to the positions shown in Figures 15 or 16 in
the Speaker Placement Section, then EzSet/EQ may not be able
to perform this test correctly.
If EzSet/EQ detects only one speaker in a pair (e.g., surround back left
but no surround back right or no main speakers), it will generate an
error and stop. If that happens, check that you have placed your speakers
in their correct locations, and that you have wired each speaker to its
correct set of speaker terminals.
Speaker Distance: During this test, EzSet/EQ measures the distance
from each speaker to the listening position. If the speakers are placed
at different distances from the listener, the sound from speakers placed
closer needs to be delayed so that it reaches the listener at the same
time as the sounds from the other speakers. This preserves the clarity
and directionality of surround sound presentations. During the Speaker
Distance test a screen similar to the one shown in Figure 52 will appear.
The speaker position will change as EzSet/EQ measures the distance
for each speaker.

NOTE: The AVR 247 is also capable of setting a different type
of delay, called A/V Sync Delay, which is used to compensate
for lip sync problems that may occur when a video display
device or set-top box causes delays while digital video signals
are processed. It simultaneously adds a delay to all speaker
channels in the system. A/V Sync Delay is not set during
EzSet/EQ. It may be set while watching a program as follows:
press the Delay Button on the remote and the first setting
displayed is A/V Sync Delay. Press the Set Button to select it
and then use the
⁄ / ¤ Buttons to adjust it.
Speaker Size: This test checks the low-frequency range capabilities
of each of your speakers to ensure that low-frequency sounds are not
sent to speakers unable to reproduce them efficiently. Each of the main
speakers in your system will be assigned a value of Large or Small,
depending solely on how it handles low frequencies. During the Speaker
Size test a screen similar to the one shown in Figure 53 will appear,
with the speaker position changing as each speaker is measured.
