DELAY TIIME UP/DOWN
control
The DELAY TIME control is effective with all modes. It
provides for continuously variable control over the
delay time.
1
NATURAL SUFL from
10
to
30
milliseconds
2
HALL SURROUND: from
10
to
30
milliseconds
3
DOLBY SURROUND: from
15
to
30
milliseconds
4 SIMULATED STEREO: from
10
to
30
milliseconds
5
LIVE SURROUND: from
10
to
30
milliseconds
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. .1\dding too much delay will cause an
unnatural effect with some sources. Experiment with
the DELAY TIME UP/DOWN control to create an effect
that you find most suitable.
*
The last setting of the DELAY TIME control is
memorized even when the power is turned off.
*
The surround sound processor is effective only
when this unit is used in a 4-speaker system setup.
Refer to the "REAR SPEAKER REPLACEMENT"
described latm.
REAR SPEAKER PLACEMENT
(See Fig.
EJ.)
The placement of a rear speaker pair in the listening
room will greatly affect the overall sound field created.
A small pair of speakers is all that is really required to
create the full effect, and the most basic speaker
placement configuration is the one shown in Fig. A.
This setup is ideal for creating a theater-like
atmosphere for movies and other video programs.
The "B" setup creates a sound field with added
depth, much like that experienced in a live concert
hall, where all the sound is coming at you from the
front. It is most appropriate for musical sources, rather
than videos.
The "C" speaker placement configuration effectively
"widens" the sound field, and is suitable for movies
and other video programs.
While the most basic speaker placement setup is
recommended at first, by experimenting with different
speaker placements for each musical or video source,
and with each surround mode, you will be able to
create a wide variety of sound field effects suited to
your listening environment, and to your own particular
tastes.
INPUT BALANCE CONTROL ADJUSTMENT
To obtain the best surround condition, be sure to
adjust the rear panel INPUT BALANCE control.
1.
Set the front panel controls as follows.
•
SPEAKERS (for the front setting) selectors - Set
to "OFF".
•
SURROUND ON/OFF switch - Set to ON.
e
SURROUND MODE buttons -
Select the "DOLBY SUR." mode.
•
REAR LEVEL control - Set to the
"10"
(maximum) position.
2.
Set the INPUT BALANCE control on the rear panel
to the center position.
3.
Play a monaural program source.
4.
Turn up the VOLUME control so that you can hear
the monaural program source through the rear
speakers.
5.
Then minimize the rear speakers' output by slightly
turning the INPUT BALANCE control clockwise or
counterclockwise until you achieve a "null" (ie.,
minimum output from your rear speakers).
NOTE:
As you approach the "null", turn up the
VOLUME control to better hear your rear speakers.
With this adjustment, the best surround balance can
be obtained.
