test
tone
to
adjust
the
volume
level
of
each
of
the
speakers
before
enjoying
Dolby
Pro
Logic
Surround.
The test tone (pink noise) is produced by each speaker in
turn so you can match the volume levels of the Front, Center
and Rear speakers. The test tone cycling sequence depends
on the center mode settings, as follows.
If CENTER MODE is NORMAL or WIDEBAND:
i Front Left—Center—> Front Right—>Rear 7
If CENTER MODE is PHANTOM:
c° Front Left—>Front Left + Right—>Front Right—>Rear 7
You can change the delay time for the sound from the rear
(surround) speakers.
Pressing the DELAY TIME button changes the delay time
every
5
msec
during
a
period
of
15
to
30
msec
in
Dolby
Pro
Logic and every 5 msec during a period of 5 to 30 msec in
Hall.
Dolby
Surround
delay
time
is
specified
at
20
msec.
It
is
recommended
that
initial
Dolby
Surround
delay
time
be
set
at
20
msec,
and
adjustment
to
either
15
or
30
possible
via
the
control.
By
adjusting
the
delay
time,
and
carefully
adjusting
Master Volume Level, Center Volume Level and Rear Vol-
ume Level, the apparent acoustic size of your listening room
can be enlarged or deduced. Adjustable delay time allows you
to tailor the acoustic size of your listening environment to
match the sonic characteristic spaces, such as concert halls,
cathedrals, etc. Use a shorter delay to simulate the size of a
small
club
or
cabaret.
Respective
delay
time
can
be
memo-
rized
for
each
surround
mode.
This
operation
can
also
be
per-
formed using the delay time button of the remote control.

When
you
