AVR
Speakers
This selection lets you program the correct setting for each speaker group. The settings
in this menu affect the remainder of the speaker setup process and the availability of
various surround modes at any time.
Select ON when the speakers are present in the system; select OFF for positions where
no speakers are installed. The Front Left & Right setting is always ON and may not be
disabled.
When you have finished, press the Back/Exit button.
Crossover
After you return to the Speaker Setup menu, navigate to the Crossover line and press the
OK button to display the Crossover menu.
The AVR will display only those speaker groups you set to On in the Number of Speakers
menu.
Refer to Table A2 to see the crossover frequencies that you wrote down for your
speakers.
For each speaker group, select one of these eight crossover frequencies: Large, 40Hz,
60Hz, 80Hz, 100Hz, 120Hz, 150Hz 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."
We recommend that you set the Subwoofer Crossover to the same frequency you used
for the Front Left & Right speaker setting. If you set the Front Left & Right speakers
to "Large", we recommend that you experiment with different Subwoofer Crossover
Frequency settings to find the one that produces the best blend between the subwoofer
and Front Left & Right speakers with your system in your room.
Write down the settings in Table A2 in the Appendix.
When you have finished entering the settings, press the Back/Exit button to return to the
Speaker 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 Speaker 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 A3 in the Appendix (see page 33). 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 line
and press the Left or Right button to change the setting.
Step Four – Setting Channel Output Levels
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 five 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).
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 Speaker 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.
