The Cinema Reference Mach II is first and foremost an auto-detect-
ing processor. As such, when it receives an input signal, it will auto-
matically determine its makeup and in turn, engage the appropriate
decoding mode. There are three primary types of signals that the
Cinema Reference is capable of decoding, a Dolby Digital encoded
signal, a DTS encoded signal, and a stereo or mono audio signal
(PCM digital audio {Pulse Code Modulation} or analog audio).
For discussion in this manual, Dolby Digital and DTS are referred to
as Cinema Modes (although they are also used for music playback).
Cinema decoding modes differ significantly from 2 Channel modes,
where there are 27 options when playing a stereo signal, there are
only 9 Cinema mode options when playing Dolby Digital or DTS
encoded material. While this seems unusual, the fact is that most of
the critical settings are automatic when playing a Dolby Digital or
DTS source, because the complex bit stream contains significant
information that permits the Cinema Reference Mach II to play the
material to perfection. To better understand the Cinema Modes,
both Dolby Digital and DTS bit streams will be examined more closely.
When wishing to select a mode
1 Turn the Mode knob until the desired mode is on the display’s
second line and press the mode knob.
When a stereo or mono source is being played, the following 2 Chan-
nel modes are active:
Stereo, Mono, DTS Neo 6, DTS Neo 6 THX, Pro Logic II - Pro Logic,
Pro Logic II - Pro Logic THX, Pro Logic II Movie, Pro Logic II Movie
THX, Pro Logic II Matrix, Pro Logic II Virtual, Pro Logic II Music, Pro
Logic II Custom 1, Pro Logic II Custom 1 THX, Pro Logic II Custom
2, Pro Logic II Custom 2 THX, Pro Logic II Custom 3, Pro Logic II
Custom 3 THX, Quad/Hex Bypass, Stereo Enhance, Mono Enhance,
Stereo 5, Mono 5, Stadium, Theater, Hall, Club, Church.
Please note, that Dolby Digital or DTS audio tracks may only con-
tain a two-channel mix. For some of these tracks, certain rules ap-
ply that may limit mode selections. Two channel digital sources may
have an encoded flags that will specifically request specific decod-
ing. Some Dolby Digital two channel mixes may specify some type
of Pro Logic decoding with the presence of a Pro Logic flag. Some
DTS two channel mixes may specify DTS Neo 6 using a similar flag.
When listening to a multi-channel encoded source, either Dolby Digi-
tal or DTS, the following Cinema modes are available:
Stereo Downmix, Mono Downmix, Discrete & Direct, Discrete, Dis-
crete & THX, Discrete and EX/ES, THX & EX/ES, THX Ultra 2 Cin-
ema, THX Music Mode.
Depending on the type of signal the Cinema Reference Mach II is
receiving, only the modes that can be engaged will be available for
selection.
