AVR
Advanced Functions
For each speaker group, select one of these eight crossover frequencies: Large, 40Hz,
50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 110Hz, 120Hz, 140Hz, 150Hz, 160Hz, 180Hz
or 200Hz. If the speaker’s crossover frequency is below 40Hz, select the first option,
“Large.” This setting doesn’t refer to the speaker’s physical size but to its frequency
response, which is also called “full range.”
NOTE: If you have Room EQ set to On, the crossover frequencies have been automatically
set by the AVR and cannot be adjusted.
Write down the settings in Table A6 in the Appendix.
When you have finished entering the settings, press the Back/Exit button to return to the
Manual Setup menu.
Select the “Speakers” menu again and note the Subwoofer setting: This setting depends
upon the Crossover setting you selected for the front left and right speakers.
If you set the front speakers to a numeric crossover frequency, the subwoofer •
setting will always be SUB. All low-frequency information will always be sent to the
subwoofer. If you don’t have a subwoofer, either upgrade to full-range front left and
right speakers or add a subwoofer at the earliest opportunity.
If you set the front left/right speakers to LARGE, select one of the three following •
settings for the subwoofer:
L/R+LFE: This setting sends all low-frequency information to the subwoofer,
including a) information that would normally be played through the front left and
right speakers and b) the special low-frequency effects (LFE) channel information.
OFF: Select this setting when no subwoofer is in use. All low-frequency information
will be sent to the front left and right speakers.
LFE: This setting plays low-frequency information contained in the left and right
program channels through the front left and right speakers, and directs only the
LFE-channel information to the subwoofer.
Distance
As described above in Step Two, when you measured the distances from each of your
speakers to the listening position, your AVR provides an adjustment that compensates
for the different distances so that the sound from each speaker will reach the listening
position at the proper time. This process will improve the clarity and detail of the sound.
On the Manual Setup menu, move the cursor to the Distance line and press the OK button
to display the Adjust Speaker Distance menu.
Enter the distance from each speaker to the listening position that you measured in Step
Two and recorded in Table A4 in the Appendix (see page 39). Select a speaker, then use
the Left/Right buttons to change the measurement. You can enter distances between 0
and 30 feet (9.1m). The default distance for all speakers is 10 feet (3m).
The default unit of measurement is feet. To change the unit to meters, select the Unit of
Measure line and press the Left or Right button to change the setting.
NOTE: If you set the Assigned AMP channels to Zone 2, you will not be able to adjust
their delay settings.
Step Four – Setting Channel Output Levels Manually
For a conventional stereo receiver, a simple balance control adjusts the stereo imaging
by varying the relative loudness of the left and right channels. In a home theater system
with up to seven main channels plus up to two subwoofers, achieving proper imaging
becomes both more critical and more complex. The goal is to ensure that each channel
is heard at the listening position with equal loudness (when signals of equal loudness
are played through them).
Your AVR’s EzSet/EQ calibration can handle this critical task for you simply and
automatically. However, the Output Adjust menu allows you to calibrate the levels
manually, either using the system’s built-in test tone or while playing source material.
From the Manual Setup menu select Output Adjust to display the speaker volume
adjustment menu.
All of the system’s speakers will appear with their current level settings. You can adjust
each speaker’s level between –10dB and +10dB in 1dB increments.
While making adjustments, you can measure the channel levels in one of these ways:
Preferably, use a handheld SPL meter set to the C-weighting, slow scale. Adjust each •
speaker so that the meter reads 75dB when the AVR’s built-in test noise is playing.
By ear. Adjust the levels so that the test tone sounds equally loud to you when it plays •
through each speaker.
To set your levels using the AVR’s internal test tone, select the menu’s Test Tone line and
use the Left/Right buttons to turn the test tone on. Then select the Test Tone SEQ line to
select between Auto and Manual:
Auto: The test tone will automatically circulate to all speakers, as indicated by the
highlight bar. Use the Left/Right buttons to adjust the level for any speaker when the test
tone is paused there. Use the Up/Down buttons to move the highlight bar to another line,
and the test tone will follow the bar. To stop the test tone, use the Up/Down buttons to
move the cursor out of the screen’s speaker listings area.
Manual: The test tone will stay on the selected speaker until you use the Up/Down
buttons to move it to another speaker. Use the Left/Right buttons to adjust the level for
the speaker through which the test tone is playing.
If you are using an external source to set your output levels, set Test Tone to Off, use the
Up/Down buttons to navigate to each speaker, and use the Left/Right buttons to adjust
the speaker’s level while the source plays.
NOTE: If you are using a handheld SPL meter with external source material, such as a
test disc or an audio selection, play it and adjust the AVR’s master volume control until
the meter measures 75dB. Then adjust the individual speaker levels.
Output Reset: To reset all levels to their factory defaults of 0dB, scroll down to this line
and press the OK button.
When you have finished adjusting the speaker levels, record the settings in Table A3 in
the Appendix. Then press the Back/Exit Button.
