2. LOW FREQ. TEST (Adjusting subwoofer level by using the test tone)
Ⅵ DESCRIPTIONS OF THE FUNCTIONS
The internal low frequency test tone generator is useful for
adjusting subwoofer level to make the subwoofer sound match
the sound of other speakers in your audio system.
Operating procedure
1. After selecting this function (title) in step 1 on page 32,
press the + or – key to display the mode for adjustment.
2. Press the key so that the arrow points to
“TEST TONE
. . . .
OFF”. Next press the + or – key to
switch to the “ON” position.
The test tone is heard from the selected speaker(s).
3. Press the key so that the arrow points to
“OUTPUT
. . . .
”. Next press the + or – key to select the
speaker whose sound you want to compare with the
subwoofer sound. The test tone is output from the selected
speaker.
* Adjust the MASTER VOLUME keys so that the test tone
can be heard at your desired listening level.
* If “SUBWOOFER” is selected, the test tone below 90 Hz
is output from the subwoofer.
* The test tone will not be necessarily output from only the
selected speaker(s). The output mode of the test tone
depends on the settings on “1. SPEAKER SET” in the
SET MENU mode.
* Even if a source is being played back, the test tone is
output instead of the source sounds.
4. Press the key so that the arrow points to
“FREQ.
. . . . . . .
88 Hz”. To confirm that the subwoofer
sound matches the sound of other speakers, change the
frequency of test tone one by one by pressing the + or –
key. (Frequency can be changed from 35 Hz to 250 Hz,
and last, all range (35–250 Hz) of frequencies are output.)
Adjust subwoofer level with the control on the
subwoofer so that the subwoofer sound matches the
sound of other speakers in any range of low frequencies.
Note
This low frequency test tone can also be applied to check the
bass response in your room. For the best bass condition, bass
sound must be heard definitely at any position in your room. If
not, change the setting of subwoofer or furniture in your room.

channels to output them from the same speakers, the ratio of
LFE signal level to the level of other signals are adjusted. (Refer
