Notes
Once you have completed these adjustments, use only this
unit's VOLUME control to adjust listening volume. Do not
change any other volume settings in this unit.
If you use external power amplifiers, their volume controls
may also be adjusted to achieve proper balance.
In the step 11, if the center mode is in the "PHANTOM", the
sound output level of the center speaker can not be
adjusted. Because in this mode, the center sound is
automatically output from the left and right front speakers.
Stop flashing and disappears.
