OPERATION

USING THE T 175 –Setup MENU

DOLBY DIGITAL EX

Using a Matrix decoder, this method creates the back channel (sometimes also called the “surround center”) by means of signals on the left and right surround channels recorded in Dolby Digital 5.1, reproduction being provided in Surround 6.1. This method should be selected with sources bearing the (double-D symbol)-EX, recorded in Dolby Digital Surround EX.

With this additional channel you will experience improved dynamics and a better sensation of movement within the sound field. If media sources recorded in Dolby Digital EX are decoded with a Digital EX decoder, the format is detected automatically, and the Dolby Digital EX mode is selected. However, some media sources recorded in Dolby Digital EX can be detected as simple Dolby Digital media sources. In this case Dolby Digital EX should be selected manually.

NOTE

Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of Pro

Logic, PLIIx Movie, PLIIx Music and Stereo Downmix modes.

DTS

The Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are

5.1channel media formats, discs bearing the “DTS” symbol are thought to provide better sound quality due to the lower audio compression required. It also offers a broader dynamic, producing magnificent sound quality.

A DTS input can be defaulted to one of the following options: - Neo:6 Music, Stereo Downmix or None.

If “None” is selected, the DTS signal will follow the “Digital” setting set forth at “Other” option under this menu section. See discussion below about “Other”.

NOTE

Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of

Stereo Downmix and DTS Neo:6 surround modes.

OTHER

If “None” is selected above for any of the Dolby Digital 2 Channel, Dolby Digital Surround and DTS options or if the audio input is an analog signal, this “Other” section will manage the default audio format as per the “Digital” or “Analog” settings.

Digital: The detected digital input can be configured by way of one of the following options

-Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced Stereo, Stereo Downmix and None.

Analog: If the audio input is an analog signal, the following are the surround modes the input can be defaulted - Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced Stereo, Analog Bypass and None.

NOTE

All these Listening Modes for “Dolby Digital”, “DTS” and “Other” can be directly changed by pressing the “LISTENING MODE” button on the front panel or through the “Listening Mode” option at the Main Menu window. The chosen audio format will be reflected back to the appropriate setting at the “Listening Mode Setup”.

DOLBY SETUP

Under this menu, the Dolby Digital’s Dynamic Range Control can be adjusted as well as the settings for Dolby Digital Pro Logic IIx Music.

Dynamic Range Control: You can select the effective dynamic range (subjective range from soft to loud) for playback of Dolby Digital soundtracks. For fully cinematic effect, always select 100%, the default. Settings of 75%, 50%, and 25% progressively reduce dynamic range, making soft sounds comparatively louder while limiting the peak loudness of loud ones.

The 25% setting will yield the least dynamic range and is best for late-night sessions or other times when you wish to retain maximum dialog intelligibility while minimizing overall volume levels. Dolby Pro Logic IIx Music: Please refer to the same description about “ADJUSTING LISTENING MODES” under the “LISTENING MODE” of the Main Menu discussions.
