3 3 Tap or repeatedly to adjust the output level of
the effect speakers so that the output level coming
from each speaker is the same.
Each speaker level can be adjusted in the range of –10 to +10
dB.
While adjusting, the test tone is heard from the selected
speaker.
Cautions
• If “1A CENTER SP” on the SET MENU is set to “NONE”,
the center channel sound is automatically output from the left
and right main speakers.
• If “1D REAR CT SP” on the SET MENU is set to “NONE”,
the output level of the rear center speaker cannot be adjusted
in step 3.
• Main L/R speaker level cannot be adjusted by itself. Use
VOLUME to adjust the main volume.
4 4 Tap to enter the TEST DSP mode.
Tap again to stop the test tone and the DSP program
name appears on the front panel display and the video monitor.
Notes
• The tonal quality of the speakers can be adjusted using the “4
CENTER GEQ”, “5 REAR CT GEQ”, and “6 CINEMA EQ”
items in the SET MENU (see pages __ to __).
• You can increase the output levels of the effect channels (left rear,
right rear, rear renter and center) to +10 dB. If the output level of
the center, rear, and rear center speakers is lower than that from
the main speakers even after you have increased the sound volume
level of the center, rear, and rear center speakers up to +10 dB, set
the “1G MAIN LEVEL” item in the SET MENU to “–10dB”.
Setting the “1G MAIN LEVEL” item to this setting decreases the
main speaker volume level to about one-third the normal level.
After you set the “1G MAIN LEVEL” item in the SET MENU to
“–10dB”, adjust the levels for the center, rear, and rear center
speakers again.
• The adjustment of output levels of the center speaker, and left and
right rear speakers is also effective to the speaker output level
during the playback of the source connected to 6CH INPUT jacks.
