The front pane! has LED lights for indicating the SURROUND MODE in use. The remote control will cycle through
the SURROUND MODES
in sequence,
from right to left. We have included MONO, 2 CH STEREO, MUSIC
MODES, DOLBY PRO LOGIC and CINEMA sound modes. (See user note above)
MONO is for AM radio, older recordings, movies or TV programs that are monophonic.
If a center channel speaker
is used in your system,
MONO mode will send sound to the CENTER speaker only.
If no
CENTER
speaker is
used,
MONO mode will send'the sound to the FRONT LEFT and FRONT RIGHT speakers only. All other channels
are muted.
The 2 CH STEREO mode is a
bypass
mode. The FRONT LEFT and FRONT RIGHT speakers are ON. All other
channels are muted.

MUSIC MODES 1, 2 or 3 delay times are variable from 15 to 20, 25 and 30 milliseconds. The apparent reflectivity
and absorption of the surfaces inside the surround sound acoustical spaces vary according to the mode setting
and delay time chosen. Music 1 will show CLUB, MUSIC 2 will show STADIUM and MUSIC 3 will show HALL in
the on screen display. The MUSIC modes have been written
to extract ambient information
from the source
material. The labels in the ON SCREEN display are
only an approximation
of the acoustical size, reflectivity or
absorption of the venue offered by the MUSIC settings. Please experiment to see which setting is most pleasant to
you with various music or video sources that are not DOLBY SURROUND encoded. In the MUSIC SURROUND
modes ALL the speakers in your system are ON.
The DOLBY PRO LOGIC setting is for CD discs, rental movies. Laser Discs, DVD discs, radio broadcasts or for
viewing films broadcast in stereo with DOLBY SURROUND encoding. Any DOLBY SURROUND encoded movie,
radio or television show that is
received in stereo
may be decoded by the DOLBY PRO LOGIC decoder.
The full directional and spatial effects of the DOLBY SURROUND encoded source material will be reproduced in
your listening room. The DELAY TIME settings are 15, 20, 25 and 30 milliseconds.
If you are sitting nearer to the
surround speakers than the front channels, a longer delay time will be the best choice.
This will ensure that the
■precedence effect" works properly. In DOLBY PRO LOGIC mode, ALL the speakers are ON. (see SETUP)
The CINEMA mode is for use with mono, stereo, or stereo hi fi movies that are
not
Dolby Surround encoded.
CINEMA mode has normal stereo left and right channels in front, mono left plus right in the center and the
surround channels are mono with delay times of 15, 20, 25 or 30 milliseconds, as with Dolby Pro Logic. We have
tailored the frequency response of to make it similar to movie filter designs suggested by various movie engineers
over the years. The bass is full range, the mid range is boosted subtly to enhance vocal intelligibility and the
highest frequencies are reduced, to eliminate excessive brightness. If you are watching an older film that seems
"bright" due to excessive high frequency response, you might find that the CINEMA mode helps you to enjoy your
film more.
The ON SCREEN display will be displayed on your TV screen when the input selector buttons on the remote
control or the front panel are pushed. The display will show the current INPUT, SRND MODE, DELAY TIME,
TONE and the MASTER VOL LEVEL setting. This will be ON SCREEN for approximately 5 seconds. Any changes
to the MASTER VOLUME setting or the LISTENING input selected will activate the ON SCREEN display. The ON
SCREEN display has a blue screen background. If no video signal is offered, it will use the blue background during
changes of settings and turn the blue screen off afterwards.
