Setting speaker levels at test mode
While at [Speaker Levels] menu, press the
TEST TONE button activating the High
Defi nition A/V Receiver's Speaker Levels
balancing test signal. You will hear a "surf"
sound as you continue testing your speakers
beginning with the Front Left. To test each
channel, use the vV buttons to move up or
down the speaker channels. If you do not hear
the test signal, check your speaker connections
or your [Speaker Setup] menu settings.
Use the vV buttons to adjust the loudness of
the noise output from the currently playing
channel to the required level (it's usually
simplest to begin with the Front Left). As you
cycle the test signal around the speakers, the
on-screen display will highlight the currently
playing channel. The "level offset" reading on
the right will change by 1 dB increments; ±12
dB adjustment is available. After adjusting a
channel, press B to effect the change in level.
Press vV to go to the next channel.
Note
•
If you are balancing levels "by ear", choose one
speaker—usually the centre— as a reference and
adjust each of the others in turn to "sound as loud"
as the reference. Be sure that you remain in the
primary listening position while balancing all channels.
•
All speakers must be in their fi nal locations before
level-setting.
•
Due to the effects of room acoustics, matched-pair
speakers (front; surround; back) will not always
calibrate to exactly the same level offset readings.
You can exit "Test" mode at any time by
pressing the BACK/EXIT button, bringing you
back to [Speaker setup] menu.
[Speaker Distance]
Speaker Distance
Front Left : 0.0 m
Center : 0.0 m
Front Right : 0.0 m
Surround Right : 0.0 m
Back Right : 0.0 m
Back Left : 0.0 m
Surround Left : 0.0 m
Your system's speaker distance settings are
a subtle but important refi nement of your
setup. Informing the High Defi nition A/V
Receiver of the loudspeaker to listener
dimensions of each speaker automatically
imposes the correct delays, optimising imaging,
intelligibility and surround-sound ambience.
Enter your dimensions with precision within
about 30 cm.
Setting speaker distance
While at [Speaker Distance] menu, use the
vV buttons to individually set the following:
[Front Left] > [Center] > [Front Right] >
[Surround Right] > [Back] > [Surround Left]
> [Subwoofer] to the distance measuring
from your principal listening position to the
front surface of their corresponding
loudspeakers. Distance can be set up to 9
metres.
