Using Advanced Sound Options
Your receiver has three special sound options: Dolby Pro Logic Surround, SFC
modes (studio and arena), and 5-D Theater. These special options enhance the
sound you hear from a program source.
Notes:
• To get the full benefit from programs encoded with Dolby Surround
Sound, you need a stereo VCR.
• Dolby Surround does not operate correctly if the signal passes through a
graphic equalizer. If you connected an equalizer to the TAPE 2 MONITOR
jacks, do not select TAPE 2 MONITOR when you listen to Dolby Surround
signals.
To activate Dolby Pro Logic Surround, press DOLBY PRO LOGIC . For SFC effects
or 5-D Theater, repeatedly press SFC MODE or 5-D THEATER until the desired op-
tion appears on the display. For Dolby 3CH Logic, repeatedly press the remote
control’s
C. MODE button until 3CHLOGIC appears on the display.
Dolby Pro Logic Surround
Dolby Pro Logic Surround puts you in the middle of the action. The center- and
rear-channel speakers add incredible realism by directing the sound to the ap-
propriate speakers, making you feel like you are really there. You can find hun-
dreds of movies, television shows, and compact discs produced with Dolby
Surround.
Dolby 3CH Logic
Dolby 3CH Logic produces a more spacious sound field than is possible with or-
dinary stereo playback by combining the front and rear speaker sounds. Select
this mode when you play a Dolby Surround Sound program and do not have
rear speakers. The rear channel’s sound is sent to the front left and right speak-
ers.
Studio Effect
Studio Effect gives the effect of listening in a recording studio. The front speak-
ers provide normal stereo, and the rear speakers provide a subtly reverberated
sound. Select this mode when you listen to sources not encoded with Dolby
Surround.
Arena Effect
Arena Effect is ideal for sources such as live performances. The front speakers
output the music, and the rear speakers output the sounds and applause of the
audience.
5-D Theater
5-D Theater provides clearer and more dynamic sound effects by outputting au-
dio signals through the rear channel to simulate the stereo sound, compared
with a standard surround system which provides only monaural signals to the
rear speakers. Select
5-D PRO LOGIC for the sources encoded with Dolby
Pro Logic, and select 5-D Surround for normal stereo sources.
