Using Test Tones to Adjust the Sound
Use the test tones to adjust the volume for each speaker independently or to verify that each speaker is working
properly. Use a sound-level meter to ensure that the tone emitted from each speaker is 75 dB. If you’re not
using a meter, make sure all the speakers sound consistent in volume.
1 Make sure the MAIN menu is displayed on the remote control, press the
MENU
button, select
Audio
,
then select
Test Tone
. You see this screen:
The speakers automatically begin emitting tones, one by one.
2 Use a sound-level meter to measure the volume from the usual seating area. Set the meter for C weight and
slow response.
Use the
u
or
d
button to move the test tone to a different speaker. Press the
u
button as needed to keep
the test tone from advancing to the next speaker.
3 Use the
l
or
r
button to change the speaker’s output. Make sure all the speakers output sound at 75 dB.
