In Dolby Pro Logic mode, the panoramic shifting speakers shift inwards pointing the center. Accordingly, they give you the same effect as if you
are using a single center speaker. When you also want to hear the sound from the center speaker, you can connect a conventional center speaker
to the terminal on the rear of the CA-MXG9BK.
Once you have set the mode, you can enter in the mode directly every time you want to enjoy the Dolby sound, as long as you don't change the
speakers or the listening room.
The soundtracks of video software bearing the Q{j{Gaeysunnou] mark* include the same encoded surround information as found in Dolby Stereo
films. The Dolby Pro Logic Surround decoder is a consumer version of the decoding process used in professional Dolby Stereo equipment, which
lets you recreate the theater ambience and effects of Dolby Stereo at home.
