DELAY TIME & DYNAMIC RANGE CONTROL
DELAY TIME
The delay time can be individually set for the Dolby
Digital/Dolby Pro Logic II modes using the DELAY
(CENTER/REAR) buttons.
When you adjust the delay time in the Dolby Digital
mode, an additional 15 ms is automatically added to the
surround channels in the Dolby Pro Logic mode. The
current setting is shown on the display.

Delay Time Setting Adjustable Range
DOLBY DIGITAL MODES:
0-15 ms in 5 ms step (S-Delay)
0-5 ms in 1 ms step (C-Delay)
DOLBY PRO LOGIC II MODE:
10-25 ms in 5 ms step (S-Delay)
In the surround modes, the sound from the speakers
should be delayed slightly, relative to that from the front
speakers.
The optimum delay time will depend on acoustic
properties, whether the walls and furnishings reflect or
absorb sound, etc.
It is recommended that you try different delay times to
obtain the best effect. The delay is digitally synthesized.
For the highest sound quality with minimum noise and
distortion, the delay time can be set independently for
each surround mode using the DELAY TIME buttons,
with the current setting shown in the display.
DYNAMIC RANGE CONTROL
This button controls the compression range of sound track.
If the compression is large (DRC = 4/4), the sound effect
is retarded to a certain range. As a result, sound effect is
not as excited as normal range DRC = 0/4). It is useful
when you want to movies at the late night.
Press DYNAMIC on remote control repeatedly until
the desired compression range reached.
