ADVANCED FUNCTIONS
Move the cursor to the BACK TO MANUAL SETUP line and press the
Set Button to return to the Manual Setup Menu.
The speaker sizes may also be configured without using the on-screen
menu system. Press the Speaker Setup Button on the remote, and
use the
/
¤
Buttons to select the desired speaker group (Front
Speakers, Center Speaker, Surround Speakers, Subwoofer). Press the
Set Button to display the current setting for the speaker group, and use
the
/
¤
Buttons again to change the setting. Press the Set Button to
return to the previous display, or wait a few seconds for the AVR to
return to normal operation on its own.
NOTE: The Speaker/Channel Indicators on the front panel of
the receiver (see Figure 82) will display the speaker size set-
tings as follows. For each speaker configured as SMALL, a sin-
gle box will appear in the position for that speaker. For each
speaker configured as LARGE, a double box will appear in its
position. If a speaker is configured as NONE, no box will appear.
The subwoofer will be indicated by a single box, or no box if no
subwoofer has been configured. The letters inside the boxes
appear when a digital
signal is being received that has that
channel discretely encoded.
The letters flash when the signal is
not present, such as when a DVD is paused.

Speaker Crossover Menu
On the Manual Setup menu, move the cursor to the SPEAKER X-OVER
line and press the Set Button to display the Speaker Crossover menu.
See Figure 83.
Figure 83 – Speaker Crossover Menu Screen
Setting the Speaker Crossover menu correctly ensures that your speakers
are properly used so that they 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.
You may select from seven possible settings: 40Hz, 60Hz, 80Hz,
100Hz, 120Hz, 150Hz or 200Hz. Depending upon the frequency
response of your speakers which you recorded in Step One –
Determine Speaker Size, for each speaker group select the number
that matches or is just above the low end of your speaker’s frequency
response. You may record the speaker crossover settings in Table A5
in the appendix.
The LFE line sets the frequency for a low-pass filter that determines
what information is sent to the subwoofer for playback. Since the sub-
woofer output combines low-frequency information for all channels, in
order to make sure that no information is lost due to different speakers
having different capabilities, the subwoofer filter should be matched to
the highest crossover frequency used for any speaker group.
Examine each of your speaker-group settings in this menu, and deter-
mine which group is set to the highest frequency. Move the cursor to
the LFE line, and use the
/
Buttons to select that speaker group.
If all speaker groups have the same setting, you may leave the LFE
filter at its factory default of the LEFT/RIGHT speaker group.
Move the cursor to the BACK TO MANUAL SETUP line and press
the Set 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, some-
times 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, you should not skip this menu.
On the Manual Setup menu, move the cursor to the DELAY ADJUST
line and press the Set Button to display the Delay Adjust menu. See
Figure 84.
Figure 84 – 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 A3 in the appendix.
The default unit of measurement is in feet. If you wish to change the unit
to meters, move the cursor down to the UNIT line, and use the
/
Buttons to change the unit to METER.
