The “Channel Level” screen reappears.
Press the ENTER button again, the “System Setup Menu” screen reappears.

To cancel the settings, select “Level Clear” and “Yes” on the “Channel Level” screen, then make the settings again.
The level of each channel should be adjusted to 75 dB (C-weighted, slow meter mode) on a sound level meter at the listening position.
If a sound level meter is not available adjust the channels by ear so the sound levels are the same. Because adjusting the subwoofer level test
tone by ear is difficult, use a well known music selection and adjust for natural balance.
NOTE: When adjusting the level of an active subwoofer system, you may also need to adjust the subwoofer’s own volume control.
*
When you adjust the channel levels while in the SYSTEM SETUP CHANNEL LEVEL mode, the channel level adjustments made will affect
ALL surround modes. Consider this mode a Master Channel Level adjustment mode.
*
After you have completed the SYSTEM SETUP CHANNEL LEVEL adjustments, you can then activate the individual surround modes and
adjust channel levels that will be remembered for each of those modes. Then, whenever you activate a particular surround sound mode, your
preferred channel level adjustments for just that mode will be recalled. Check the instructions for adjusting channel levels within each
surround mode on Page 36.
*
You can adjust the channel levels for each of the following surround modes: DIRECT, STEREO, 5CH STEREO, DOLBY/DTS SURROUND,
ROCK ARENA, JAZZ CLUB, VIDEO GAME, MONO MOVIE, and MATRIX.
