Hooking Up and Setting Up the Speaker System
Tip
Internally, the LARGE and SMALL settings for each
speaker determine whether or not the internal sound
processor will cut the bass signal from that channel.
When the bass is cut from a channel, the bass
redirection circuitry sends the corresponding bass
frequencies to the sub woofer or other “LARGE”
speakers.
However, since bass sounds have a certain amount of
directionality, it best not to cut them, if possible.
Therefore, even when using small speakers, you can
set them to “LARGE” if you want to output the bass
frequencies from that speaker. On the other hand, if
you are using a large speaker, but prefer not to have
bass frequencies output from that speaker, set it to
“SMALL”.
If the overall sound level is lower than you prefer, set
all speakers to “LARGE”.
x Sub woofer selection (
SW
)
• If you connect a sub woofer, select “S.W. YES”.
• If you do not connect a sub woofer, select
“S.W. NO”. This activates the bass redirection
circuitry and outputs the LFE signals from other
speakers.
• In order to take full advantage of the Dolby
Digital bass redirection circuitry, we
recommend setting the sub woofer’s cut off
frequency as high as possible.
Adjusting the speaker level
Use the remote while seated in your listening
position to adjust the level of each speaker.
Note
The amplifier incorporates a new test tone with a
frequency centered at 800 Hz for easier speaker level
adjustment.
1
Press ?/1 to turn on the amplifier.
2
Turn MASTER VOLUME on the
amplifier clockwise (until 10 to 20
appears in the display).
3
Turn on the power of the sub woofer.
4
Turn LEVEL on the sub woofer
clockwise (about
position).
5
Press TEST TONE.
You will hear the test tone from each
speaker in sequence.

6
Adjust the level parameters so that the
level of the test tone from each speaker
sounds the same when you are in your
main listening position.
To adjust the balance and level of speakers,
press MENU </> on the remote to select the
level parameter you want to adjust (page 22).
Then press MENU +/– to select the setting.
7
Press TEST TONE again to turn off the
test tone.
Tip
You can adjust the level of all speakers at the same
time. Turn MASTER VOLUME on the main unit or
press MASTER VOL +/– on the remote.
Notes
• The test tone is not output when the MULTI CH IN
function is on.
• The front balance, surround balance, center level,
surround level, and sub woofer level are shown in
the display during adjustment.
• Although these adjustments can also be made via the
front panel using the LEVEL menu (when the test tone
is output, the amplifier switches to the LEVEL menu
automatically), we recommend you follow the
procedure described above and adjust the speaker
levels from your listening position using the remote.
• To enjoy the better sound quality, do not turn the
volume of the subwoofer too high.
