The SURROUND modes make full use of additional loudspeakers at the
center, sides and rear of the room. TELEVISION provides surround effects
for television viewing of monaural, stereo, and stereo synthesized pro-
grams. MUSIC is a 7-channel ambience extraction mode, appropriate for
any type of music. It also provides a unique way to listen to films, particu-
larly stereo films which are not Dolby surround encoded. FULL (Full
Range) allows unprocessed music to be played over all the speakers for
background music, or for maximum acoustical output of the system.
MONO LOGIC takes a monaural soundtrack and sends music and sound
effects to the sides and rear through a room simulator mode, while keeping
dialog in the center. PRO LOGIC is Lexicon's all-digital implementation of
the Dolby Pro Logic Surround decoding process. Home THX Cinema is
designed for any surround sound encoded movies, music, or television
programs. Because each Surround mode makes use of different configura-
tions, the EFFECT LEVEL control will be described separately at the
beginning of each set of parameter descriptions.
* Off if center speaker configured as NONE;
** BYPASS if center speaker configured as NONE or FULL;
95 Hz if configured as SMALL (Presets only)
*** Inaccessible if side speakers configured as THX or NONE
EFFECT LEVEL controls the loudness of the front, side and rear outputs.
SURROUND EFFECT The Stereophonic setting provides extraction of five
channels of surround information from a standard 4-2-4 matrix-encoded
soundtrack (Dolby Surround, Ultra*Stereo, etc.) The drama of this effect is
dependent on the source material, and will be most noticeable with strong
stereo music soundtracks. The Decorrelate setting
"scrambles" the monaural surround channel to provide added spaciousness
and envelopment.
FRONT STEERING The essence of the Television mode is that dialog, music
and sound effects are dynamically directed to the output channels, a process
called steering. The FRONT STEERING control allows you to adjust the
amount of steering in the front channels. When this control is set to Full, the
effect is identical to Dolby Pro Logic. At the Half setting, steering is reduced
to accommodate the wide range of television programming. Selecting OFF
will steer the center signal to both the left and right channels.
