Center speaker.
PHANTOM: Select this mode if your system lacks the
Center speaker. In this mode, you can hear the sound
originally allocated to the Center channel from the Left and
Right front speakers. Without the Center speaker, place the
front speakers as close to the monitor TV as possible, making
sure that the screen color on the monitor TV is not affected.

speaker placement (using the remote controller).
The possible delay time settings are 15, 20, 25 or 30 ms.
(For details, see “Setting the delay time” below.)

speaker channel so that you hear the same sound volume
from each speaker at the listening position(using the

front speakers. While listening to the test tone, adjust the
output levels of other speakers.
This adjustment is normally made from the listening position
using the remote controller.

Setting the delay time
“Delay time” is set according to the distance from the Center
and Surround Speakers to the listening position.
• In the DOLBY PRO LOGIC mode
Set the proper delay time for your listening position and speaker
placement.
Measure the distance from your listening position to the Center
speaker (L1) and to the Surround speakers (L2). Then, choose
the correct delay time in the table below according to the
difference between L1 and L2.
Ex.
Assume, in the figure on the left, that the distance from the Center
speaker to your listening position (L1) is 2 meters and the distance
from the Surround speakers to your listening position (L2) is 3.5
meters. Since the difference between L1 and L2 is 1.5 meters, the
table indicates that the correct delay time is 20 ms.
• In the HALL, LIVE, or ARENA mode
Set the delay time according to your taste while listening to the
sound. The possible delay time settings are 15, 20, 25, 30, 40,
50 or 60 ms.
