DTS 5.1 Surround
Source material encoded in DTS 5.1 Surround operate in a manner
similar to Dolby Digital 5.1 Surround material. When playing soft-
ware encoded in DTS 5.1 Surround, the DTS lamp will illuminate
along with the L, C, R, LFE, LS, and RS Input lamps. Selecting a
more basic Discrete mode will engage the L, C, R, SUB, LS, and RS
Output lamps.
Again, like Dolby Digital 5.1 material, selecting an EX/ES mode will
send audio to the back surround speakers activating the ES lamp as
well as L, C, R, LFE, LS, RS, SBL, and SBR Output channel lamps.
This feature performs similar to the EX feature for Dolby Digital 5.1
tracks.Also, like Dolby Digital 5.1 material, selecting a THX or THX
Ultra 2 mode will engage the appropriate THX enhancements and
activate the THX indicator lamp.
DTS ES Matrix
Much like Dolby Digital Surround EX, DTS ES Matrix encoded ma-
terial contains the ES flag in the digital bit stream, indicating that this
track was specifically mixed on a system with back surround speak-
ers. When on a more basic Discrete mode, playing a disc track that
contains an ES flag, will cause the DTS and ES symbols to illumi-
nate along with the Digital symbol. The number of Output channels
is not effected by the ES flag unless and EX/ES or THX Ultra 2
mode is selected. Then the BSL and BSR Output channel lamps
will engage with audio from the back surround speakers. Again, like
DTS 5.1 Surround, Dolby Digital 5.1 Surround, or Dolby Digital Sur-
round EX, all Cinema Mode features, as previously described, are
available.
DTS ES Discrete
A disc containing a DTS ES Discrete audio track is unlike the other
5.1 or 5.1 with EX/ES encoding formats. DTS ES Discrete material
has a sixth discrete channel in addition to LFE. Hence it is a true 6.1
format. Furthermore, the decoding process electronically manipu-
lates this channel such that it acts more like a full seven channel
system in addition to LFE (7.1). At the time of this printing, DTS ES
Discrete material is the only software that provides a true eight chan-
nel input.
When playing a DTS ES Discrete audio track, the Cinema Refer-
ence Mach II will detect the ES Discrete flag in the digital bit stream.
If you are on even the more basic Discrete mode, the Cinema Ref-
erence Mach II indicate all channels; L, C, R, LFE, SL, SR, SBL, and
SBR on the Input channel lamps. This is the only time that the SBL
and SBR Input channel lamps will engage. Furthermore, because
of the presence of the DTS ES Discrete flag, the ES indicator will
also engage in addition to the L, C, R, SUB, SL, SR, SBL, and SBR
Output channel lamps. Note, that with DTS ES Discrete material,
you do not need to select an EX/ES or THX Ultra 2 mode in order to
engage the back surround channels. For this decoding format, all
Cinema modes, as previously described apply.
