With this unit’s built-in Dolby Digital decoder and surround
speaker system (the center and surround speaker units supplied
in addition to the left and right front speakers), video software
recorded in Dolby Digital or Dolby Pro Logic can be played back
in full scale home theater sound.
Dialogs are heard in the front and center sound field, while
ambient sounds like cars and crowds are reproduced on all sides
of the listener, all in all for an incredibly lifelike audio-visual
experience.
Dolby Pro Logic has four independent channels; left, center,
right, and surround. These four channels are encoded into the
two tracks of a conventional stereo program source. This unit’s
Dolby Digital decoder recovers these four channels on playback.
Dolby Pro Logic software is marked with the
H logo.
Dolby Digital, in contrast to Dolby Pro Logic, is digitized,
and has separate left and right surround channels plus an
additional low-frequency effects (LFE) channel. Thus it is also
referred to as “5.1-channel” Dolby Digital, with the LFE channel
counted as “0.1” channel.
Dolby Digital software is marked with the
logo.
