DOLBY PRO LOGIC IIx 

Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby 

Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience 

to the source material. Dolby Pro Logic IIx surround processing 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. For two channel signals, Pro Logic IIx Music mode also features three additional user 

controls - Dimension, Center Width, and Panorama. See also section about ‘Adjusting Listening Modes’ 

below.

The following chart shows the channels available assuming they are enabled in the ‘Speaker 

Configuration’ menu:

DTS NEO: 6

Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo: 6 surround 

with output to front left/right, center and discrete left/right surround channels plus subwoofer 

(assuming these are present in the current ‘Speaker Configuration’). The T 765 provides two DTS Neo: 6 

variations - NEO:6 Cinema and NEO:6 Music. See also section about ‘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 front left/right, center and discrete left/right surround 

channels, plus subwoofer (assuming these are present in the current ‘Speaker Configuration.’). 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. Its virtues include 

realistic, stable “front-stage” sonic imaging and spacious but unexaggerated ambient “virtual acoustics” 

that remain faithful to the original recording.

ENHANCED STEREO

All recordings are reproduced in stereo via the maximum speaker complement configured in the 

current ‘Speaker Configuration.’ Enhanced stereo can be useful for maximum volume from all channels 

or for multi-speaker background music (cocktail party) listening. For this mode, Front, Center, Surround 

and Back speakers can be turned ON/OFF as desired.

ANALOG BYPASS

All analog signals remain in the analog domain without analog-to-digital conversions. At Analog 

Bypass, the DSP circuitry is bypassed but full tone control functions remain. ‘Bass management’ or 

Speaker settings are also not in effect as these are DSP functions.
