1 Press –/+ to set “TEST TONE” to ON, and
adjust the volume with VOLUME +/– so you
can hear the tone.
Notes
• Do not turn up the volume too high.
• If no test tone is heard, turn down the volume, set this unit in
the standby mode and make sure all the necessary connections
are correct.

not necessarily be output from the selected speakers.
The output mode of the test tone depends on the
settings of “1 SPEAKER SET” on the SET MENU.
3 Press n to go to “FRQ” and press –/+ to
select the frequency you want to use.
4 Adjust the volume of the subwoofer with the
controls on the subwoofer so it matches that
of the speaker you are comparing it to.
■ About the test tone
The test tone is produced by the tone generator.
The tone generator produces a narrow-band noise
centered on a specified frequency by the band pass filter.
You can change this center frequency from 35 Hz through
250 Hz in one-sixth octave steps.
You can use the test tone not only for adjusting the
subwoofer level, but also for checking the low-frequency
characteristics of your listening room. Low-frequency
sounds are especially affected by the listener’s position,
speaker placement, subwoofer polarity and other
conditions.
