1 Press +/– to set “TEST TONE” to “ON”.

Cautions

“ON” cannot be selected when the headphones are being used.

Setting turns to “OFF” if the headphones are connected during testing.

While the test tone is being output, the source sound cannot be output.

2 Adjust the volume with VOLUME +/– so you can hear the tone.

Cautions

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.

3 Press to go to “OUTPUT” and press +/– to select the speaker you want to compare with the subwoofer.

If “SWFR” is selected, the test tone above 90 Hz will not be output from the subwoofer. The test tone will 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.

4 Press to go to “FREQ.” and press +/– to select the frequency you want to use.

Set the center frequency (35 – 250 Hz or “35-250Hz”) to check that the subwoofer level matches that of the other speakers.

5 Adjust the volume of the subwoofer with the controls on the subwoofer so it matches that of the speaker you are comparing it to.

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.
