PRO LOGIC IIx
PLIIx MOVIE is optimized for film soundtracks.
PLIIx MUSIC for music recordings.
CENTER WIDTH (0 to 7): Modifies the "hard-centeredness" of the center image, by gradually mixing
mono center content to the Front left/right speakers as well. A setting of 0 retains the center-
channel-only default while a setting of 7 yields a fully phantom center channel.
DIMENSION (-7 to +7): Adjusts front-rear emphasis of the surround effect independently from the
relative channel levels.
PANORAMA (On/Off ): Adds a "wrap around" effect by extending some stereo content into the
surround channels.
NOTES
• Pro Logic IIx mode will decode as Pro Logic II mode when the BACK surround speakers are set to
"Off" from "Speaker Configuration" menu. See also section about "SPEAKER CONFIGURATION"
under "SPEAKER SETUP" of the Setup Menu.
• The mention of "Back Right" and "Back Left" refer to your external amplifier's corresponding "Back
Right" and "Back Left" speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it
possible to use the T 755 as a pre-amplifier to external power amplifiers for some or all channels.
NEO:6
Neo:6 Cinema is optimized for film soundtracks.
Neo:6 Music for music recordings.
CENTER GAIN (0 to 0.5): Adjust for better center image in relation to the surround sound channels.

DSP OPTIONS

DSP Options has the feature "Lip Sync Delay" whose function is to match any delay that may occur in
the picture relative to the audio.
By varying "Lip Sync Delay" from 0ms to 120ms, one can delay the audio output in order to synchronize
it with the video image.

TONE CONTROLS

The T 755 has Bass and Treble Tone Control levels which only affect the low bass and high treble
leaving the critical midrange frequencies free of coloration.
These controls allow one to tweak on-the-fly, the frequency response of the source during playback.
The control setting could be adjusted by navigating through the Tone Controls OSD menu via a
combination of [ENTER] and [ ] keys. The same can be managed directly by pressing the front
panel's "TONE CONTROLS" button and then rotating the Volume knob to select desired setting.
Maximum and minimum values for both Tone Control levels are +/- 10 dB.
"Tone Defeat" gives one the choice of varying or completely bypassing the tone control section of the
T 755. If "Off" (Tone Active in the VFD) is selected, the Tone Control circuits are active.
Select "On" to bypass the Tone Controls effectively defeating the effect of the tone control circuits.
