OPERATION

USING THE T 175 – MAIN MENU

ADJUSTING LISTENING MODES

Several of the T 175’s listening modes have one or more selectable variations and adjustable parameters that you can modify to suit your personal preferences. At Listening Mode menu, use a

combination of the [ENTER] and [ ] keys to navigate and effect desired settings.

NOTE

Listening Mode parameter changes are maintained when you change listening modes. You may also save a modified Listening Mode for easy recall by saving it to a Preset (See “A/V Presets” below under Setup Menu discussions).

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 “wraparound” effect by extending some stereo content into the surround channels.

NOTE

Pro Logic IIx mode will decode as Pro Logic II mode when the BACK surround speakers are set to “Off” from “Speaker Configurations” menu. See also section about “SPEAKER CONFIGURATIONS” under “SPEAKER SETUP” of the Setup Menu.

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 175 has three Tone Control levels – Treble, Bass and Center Dialog. Bass and Treble controls only affect the low bass and high treble leaving the critical midrange frequencies free of coloration. The Center Dialog control boosts the “presence” of the midrange region improving intelligibility of speech.

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 all three Tone Control levels are +/- 10 dB

“Tone Defeat” gives one the choice of varying or completely bypassing the tone control section of the T 175. 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.
