SURROUND MODE
With the SURROUND MODE keys (5) you can select 7
different surround modes: D0 PRO LOGIC, ...3CH, HALL,
STADIUM, THEATER, SIMULATED, OFF.
DOLBY PRO LOGIC; choose this setting for playback of
movies and music (especially Laser Discs, videocassettes and
TV broadcasts with DOLBY SURROUND sound). Not only does
Dolby Pro Logic surround you with sound, it also gives you a
clear perception of the position and direction of the sound.
Make sure you ‘Speaker Positioning’ is correct (page 5).
DOLBY 3-STEREO (...3CH): choose this setting for playback of
movies and music (especially Laser Discs, videocassettes and
TV broadcasts with DOLBY SURROUND sound), when not
using rear speakers. You get a clear perception of the position
and direction of the sound.
HALL: with this setting, you get the spacious effect of a con-
cert hall when playing stereo (but not mono) source material.
STADIUM: the reverberation and open air atmosphere of a
rock concert or sporting event is created by this setting, when
playing stereo (but not mono) source material.
THEATER: this setting creates the same intimate feeling as
you get in a theater when watching plays, musicals and solo
acts.
SIMULATED: this setting gives you spatial surround sound
when playing mono source material.
OFF: switches off the center and rear speakers for normal
stereo operation.
Note: Dolby Pro Logic and Dolby 3-Stereo will not work
properly if the signal passes through a graphic equalizer.
Please refer to your equalizer user manual for guidance on
switching off (or defeating) the equalizer.
When you select a SURROUND MODE the respective name
appears on the display. The SURROUND MODE is switched
off when you press the OFF key.
Each mode has programmed values for center-mode, center
and rear levels and for rear channel time delay (as appropriate).
With the CURSOR MODE and the V DOWN, A UP, + — keys
your can set other values. These values will then be kept in the
memory until they are changed again. Increasing the rear delay
time expands the perceived listening area, and vice versa.
