INITIAL SETUP
Setting the Speaker Crossover menu correctly ensures that your speakers
sound their best. Although you could skip this step the first time you use
the receiver, we recommend that you take the few extra minutes to
enter the correct crossover settings.
Select from seven possible settings: 40Hz, 60Hz, 80Hz, 100Hz,
120Hz, 150Hz or 200Hz. For each speaker group, select the number
that matches or is just above the low end of your speaker’s frequency
response, which you recorded in Step One – Determine Speaker Size.
Record the speaker crossover settings in Table A6 in the Appendix.
The LFE line sets the frequency that determines what information is
sent to the subwoofer. The subwoofer output combines low-frequency
information for all channels. To make sure no information is lost, set the
LFE line to the speaker group with the highest crossover frequency.
Move the cursor to the LFE line, and use the
/
Buttons to make
a selection. If all three speaker groups have the same setting, leave
the LFE filter at its factory default of LEFT/RIGHT.
Move the cursor to the BACK TO MANUAL SETUP line and press the
OK Button to return to the Manual Setup menu.
It is not possible to adjust the speaker crossover settings without using
the on-screen menu system.
Delay Adjust Menu
As explained above in Step Two – Measure Speaker Distances,
sometimes the speakers are placed at different distances from the
listening position, which can muddy the sound, as sounds are heard
earlier or later than desired.
Even if all of your speakers are placed the same distance from the
listening position, do not skip this menu.
In the Manual Setup menu, move the cursor to the DELAY ADJUST
line and press the OK Button to display the Delay Adjust menu.
See Figure 46.
Figure 46 – Delay Adjust Menu Screen
This menu requires you to enter the distance from each speaker to the
listening position, which you measured in Step Two – Measure Speaker
Distances and noted in Table A4 in the Appendix.
The default unit of measurement is in feet. If you wish to change the
unit to meters, move the cursor to the UNIT line, and use the
/
Buttons to change the unit to METER.
Use the
/
¤
Buttons to move the cursor to the FL (front left) line;
then use the
/
Buttons to change the measurement as needed.
Use the
/
¤
Buttons to move to each speaker in turn – CEN
(center), FR (front right), SR (surround right), SL (surround left) and
SUB (subwoofer).
DELAY RESET: This line is used to reset all of the speaker delay
settings to the factory default of 10 feet (3.0 meters) at once. Use the
/
Buttons to change the setting of OFF to ON. If you change any
speaker’s setting, this line will automatically revert to OFF.
A/V SYNC DELAY: This line allows you to compensate for a “lip sync”
problem, in which a source device or the video display introduces
a significant amount of video processing that causes the audio and
video parts of the signal to lose synchronization. You may delay the
audio for all channels by up to 180 milliseconds to compensate.
NOTE: We recommend adjusting the A/V Sync Delay using the
Delay Button on the remote, so as to view the picture while
adjusting the audio delay. With the program playing, press the
Delay Button, and the A/V SYNC DELAY message will appear
on the front panel and in the semi-OSD display. Press the
OK Button to display the current delay setting, and use the
/
¤
Buttons to adjust the setting until the picture and sound
are back in sync.
Move the cursor to the BACK TO MANUAL SETUP line and press the
OK Button to return to the Manual Setup menu, or press the OSD
Button to exit the menu system.
You may adjust the delay settings without using the on-screen menu
system. Select a surround mode that uses all of the speakers in your
system. Press the Delay Button on the remote to display the A/V SYNC
DELAY message. If you wish to adjust A/V Sync Delay as described in
the above note, press the OK Button to select it. Otherwise, use the
/
¤
Buttons to scroll through the list of all loudspeakers in your
system. Press the OK Button when the speaker you wish to adjust is
displayed, and use the
/
¤
Buttons again to change the setting.
Press the OK Button to return to the previous display, or wait a few
seconds for the AVR to return to normal operation on its own.
Step Four – Output Level Calibration
This is an important step in the configuration process, and should not
be skipped.
Many people assume that during a presentation, such as a movie, the
surround channels will sound as loud as the front channels. However,
this is usually not the case, as directors often steer just the ambient or
background sounds to the surround channels. For example, during a
rainy scene you may only hear rain falling, with the occasional thunder-
clap, from the surround speakers while the main dialogue is heard from
the center speakers. At times, you may not hear any sounds at all from
the surround channels.
To achieve these effects successfully, it is important that the surround
channels sound as loud as the other channels when a test tone is
played. Therefore, calibrating the speaker output levels so that all speakers
