USING THE T 744
The following Surround Sound Modes require a specially encoded signal that must be present in digital
format to be decoded by the T 744. These modes are automatically switched on when the appropriate data
stream is detected selected in the setup menu of the source media.
• Dolby Digital
• DTS
Digital recordings in Dolby Digital or DTS formats are reproduced via the channels employed in the original
recording (up to the maximum channels present in the current <Speaker Settings> setup).
NOTE: The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. Your DVD
player probably includes its own setup menu that (among other things) lets you select the default bit-
stream format, and usually includes an “Auto” setting that directs the player to choose the Dolby Digital/
DTS signal whenever these are available. In a few cases, you may have to set the player’s bit-stream
manually to “DD/DTS” or an equivalent. In the case of DVDs that carry both Dolby Digital and DTS, you
will select one or the other from the disc’s (not the player’s) main menu.
Note also that while most Dolby Digital recordings are 5.1-channel surround productions, older examples
may be multichannel, 2-channel, or even monaural; the T 744 will automatically reproduce the Dolby
Digital signal with the maximum number of channels available.
The table below indicates which listening modes are available with the two types of audio signal sources:
digital- or analog-input 2-channel (whether the actual signal is monaural, stereo or surround-encoded), and
digital-multichannel (Dolby Digital or DTS). Where a listening mode is not available to a given signal source,
it will not appear in the <Listening Mode> selection rotation.

Keying the front panel’s DISPLAY or HTR 2 remote's [DISP] key will display on the VFL the channel-mode of
the currently selected input signal, in the format “front/surround.subwoofer” (see “5 DISPLAY” in the
“Front Panel” section).
The following table shows examples of displays seen with various signal types:
Source Readout/OSD
Analog Analog
Digital PCM/HDCD Digital PCM/HDCD

Keying the HTR 2 remote's [SURR MODE] button steps through each of the T 744’s Listening Modes available
to the current input signal. It also momentarily displays the Listening Mode in the OSD.
NOTE: Changing the type of input signal may automatically change the Listening Mode: If the new signal
is a Dolby Digital or DTS recording, it will automatically invoke its native mode. The reverse is also true
if Dolby Digital or DTS was previously selected.
