Adjustment of DELAY TIME
You can adjust the time difference between the beginning of
the source sound and the beginning of the effect sound with
the DELAY TIME control.
The DELAY TIME control is effective with all programs.
By applying more or less delay, sound effects, background
noise, and ambient noise coming at you from the rear speakers
can be enhanced or subdued for extra effect.

If desired, adjust the delay time and the output level of
each speaker. (For details, refer to the corresponding
descriptions on this page and the next page.)
Note
If you prefer to cancel the selected program, press the OFF
switch. The sound will be the normal 2-channel stereo without
surround sound effect.
By continuously pressing "+" or "–" of the DELAY TIME
control, the value changes continuously.
However, the value stops changing momentarily at the
preset point.
Note
Adding too much delay will cause an unnatural effect with
some sources. Experiment with the DELAY TIME control to
create an effect that you find most suitable.
Adjustable.
