Technics SH-AC500D Operating Instructions

Delay time adjustments
By adjusting the delay time, the difference in the distance from the
viewing and listening position to the front speakers and the distance
to the center speaker and surround speakers can be offset and
made equal. This achieves better sound localization and makes a
more life-like reproduction of the sound field possible.

Press SURROUND to select the surround
mode.
“SURROUND” appears on the display.

Press DELAY to select the channel to be
adjusted.
Each time the button is subsequently pressed, the channel
whose delay time is to be set is selected alternately:
C (Center speaker) — S (Surround speakers)
For each channel, the delay time is displayed, and the
speaker indicator for the corresponding speaker flashes.
The display is restored if a button isn’t pressed for 4 or more
seconds.
Speakers for which NONE has been set are skipped.
Press [-] or [+] to set the delay time.
When the button is pressed, the current delay time is
displayed. Each time the button is pressed, the delay time will
change. The delay time increments are different depending
on the speaker as follows.
Available delay time setting (ms)
0,1,2,3,4,5
E 0, 5, 10,15
