PCM Digital Audio
PCM digital audio (Pulse Code Modulation) is the stereo audio that is digitally encoded onto CDs and
laser discs, as well as the audio output of some broadcast receivers. For standard PCM digital audio, no
prior decoding takes place to derive the stereo signal (as in Dolby Surround 2.0). Material encoded in
Dolby 2.0 can also be decoded in any of the two channel modes described below.
Analog Audio (Stereo or Mono)
As with two channel PCM or Dolby Digital audio, the Suite 7.1 is capable of processing standard two
channel analog signals with all of the two channel modes described below.
Two Channel Decoding Modes
The Suite 7.1 can decode two channel signals in Dolby Surround 2.0, digital PCM or two channel
analog audio in any of the modes listed below including any enhancements you choose to add.
STEREO - This two channel mode will active only the left and right speakers along with the subwoofer.
MONO - In this mode, only the center channel and the subwoofer are active. If a stereo signal is in
play, both right and left channels mix to mono and play through the center speaker.
DTS NEO 6 - DTS Neo 6 is one of the few Two Channel modes that will permit you to engage your
entire speaker array (7.1) when playing a two-channel source. Here, the L, C, R, SUB, LS, RS, SBL,
and SBR Output channel lamps are on and all speakers are active.
DTS NEO6+THX - This mode is the same as DTS Neo 6 and includes the addition of THX
enhancements.
PROLOGIC - Pro Logic decoding is a matrix decoding mode for two-channel soundtracks and
works best with material that was specifically encoded in Dolby Surround. Here the surround channels
have a mono, not stereo sound field.
PROLOGIC THX - This mode is the same as Pro Logic and includes the addition of THX
enhancements. Here, the L, C, R, SUB, LS, and RS Output channel lamps are on, all speakers are
active, and the THX symbol is illuminated.
PLII MOVIE - Pro Logic II Movie decoding is an advanced matrix decoding mode for two-channel
film soundtracks and is optimized for programs or movies that are encoded in Dolby Surround. Here
the surround speakers have greater spatial separation, providing a more stereo like sound field. This
mode is also appropriate for video games. This mode retains the important features of Pro Logic, but
with full-bandwidth stereo surround output, the listening experience is much closer to the sound you
get from Dolby Digital.
