DOLBY PRO LOGIC
Dolby Pro Logic is a surround format consisting of four channels (front right, centre, front left and surround.
Media sources with the “Dolby Surround” feature produce a theatre–like surround sound. The surround
channel is monophonic, but it is reproduced in both surround speakers.

This mode applies conventional 2-channel signals such as digital PCM or analog stereo signals as well as
Dolby Surround signals, etc. to surround processing which offers improvements over conventional Dolby Pro
Logic circuits. Dolby Pro Logic II surround has two decoding modes:

The T 754 receiver offers nine distinct listening modes, tailored for different types of recordings or program
material. The table below lists which modes are available to what input signals.
With a two-channel (STEREO) source the following listening modes can be selected:
• Stereo
• Downmix
All output is directed to the left/right-front channels; low frequencies are directed to the subwoofer if one
is present in the Speaker settings. Select Stereo when you wish to listen to a stereo (or monaural)
production, such as a music CD or FM broadcast, without surround enhancement. Stereo recordings,
whether in PCM/digital or analog form and whether surround-encoded or not encoded, are reproduced
as recorded; multichannel digital recordings (Dolby Digital and DTS) are reproduced in “Downmix” mode
via the left- and right-front channels only, as Lt/Rt (left/right-total) signals.
• Dolby Pro Logic
• Dolby Pro Logic II (PLII)
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro Logic, or
ProLogic II surround processing, yielding output to left-, center-, and right-front channels, and discrete
left/right surround channels (assuming these are present in the current <Speakers Setup>. PLII does not
employ the surround back speakers (if any).
NOTE: ProLogic II is a more recent evolution of the original Dolby ProLogic surround processing that yields
more stable imaging and full bandwidth sound to the rear channels in Movie mode, offering sound that
is more similar to Dolby Digital decoding.
The T 754 provides two PLII variations: MOVIE and MUSIC. See “Adjusting Listening Modes,” below.
• DTS Neo:6
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround with
output to left, center-, and right-front channels and discrete left/right surround channels (assuming these
are present in the current <Speakers Setup>).
The T 754 provides two DTS Neo:6 variations: CINEMA and MUSIC. See “Adjusting Listening Modes,”
below.
• EARS
Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD
surround processing with signals output to the left, center-, and right-front channels and discrete left/
right surround channels, plus subwoofer (assuming these are present in the current <Speakers Setup>);
EARS does not employ the surround back speakers (if any). EARS extracts the natural ambience present
in nearly all well-produced stereo recordings. It does not synthesize any ambience or other sonic elements
and thus remains truer to the sound of the original musical performance than most other music-surround
options.
Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly
natural and believable ambience from nearly all "natural-acoustic" stereo recordings; typically, these
include classical, jazz, and folk genres as well as numerous examples from others. It's virtues include a
realistic, stable "front-stage" sonic imaging and spacious but unexaggerated ambient "virtual acoustics"
that remain faithful to the original recording.
• Matrix 7.1
Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary surround
processing via the full suite of front, surround, and one or two surround back speakers (if these are
present in the current Speaker Settings setup), plus subwoofer (if any). Matrix 7.1 can produce a very
natural, cohesive all-channels surround from high-quality recordings, both for stereo music and for
surround-encoded music or movie programs.
• Enhanced-Stereo 1 (ST1)
All recordings reproduced in stereo via the maximum speaker complement configured in the current
<Speakers Setup>. ST1 can be useful for maximum volume from all channels, or for multi-speaker
background music (cocktail party) listening.
