Set the Speaker Distances
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 Speaker Setup menu, move the cursor to the Distance line and press
the OK button to display the Adjust Speaker Distance menu.

Adjust Speaker Distance
10.0 ft
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 46). 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, return to the
main AVR menu. Select the System Settings menu, then scroll down to the General
Setup section and select the Unit of Measure line. Press the OK 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 a subwoofer, 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 AVR’s Adjust Speaker Levels menu allows you to
calibrate the levels manually, either using the system’s built-in test tone or while
playing source material.
Press the Setup button to display the menu system, and then navigate to the Speaker
Setup line. Press the OK button to display the Speaker Setup menu. Select Manual
Setup, press the OK button, and then navigate to the Level Adjust line. Press the OK
button to display the Adjust Speaker Levels menu.

Adjust Speaker Levels
0 dB
Test Tone Off
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 OK button 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 cursor to another
line, and the test tone will follow the cursor. 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 current 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.
Reset Levels: To reset all levels to their factory defaults of 0dB, scroll down to this
line at the bottom of the menu and press the OK button.
When you have finished adjusting the speaker levels, record the settings in Table A3
in the Appendix. Then select the Back option or press the Back/Exit Button.
Notes on Setting Speaker Volumes in Home Theater Systems:
While setting your system’s individual speaker volume levels is ultimately up to your
personal taste, here are some ideas you may find helpful:
• For films and video-music programs, your overall goal should be to create an
enveloping, realistic sound field that draws you into the film or music program
without drawing your attention away from the action on the screen.
• For multichannel music recordings, some music producers will create a sound
field that places the musicians all around you; others will create a sound field that
places the musicians in front of you, with more subtle ambience in the surround
speakers (as you would experience in a concert hall).
• In most 5.1-channel and 7.1-channel film soundtracks, the surround speakers
are not intended to be as loud or as active as the front speakers. Adjusting
the surround speakers so they are always as loud as the front speakers could
make dialogue difficult to understand and will make some sound effects sound
unrealistically loud.
Notes on Setting Subwoofer Volume:
• Sometimes the ideal subwoofer volume setting for music is too loud for films,
while the ideal setting for films is too quiet for music. When setting the subwoofer
volume, listen to both music and films with strong bass content and find a “middle
ground” volume level that works for both.
• If your subwoofer always seems too loud or too quiet, you may want to place it in
a different location. Placing the subwoofer in a corner will always tend to increase
its bass output, while placing it away from any walls or corners will always tend
to lessen its bass output.
