de-activate the digital input, e.g. Video 1. By pressing
the Digital Audio Selector button you can toggle
between the Digital input to be active (“DIGITAL” is
shown in the display area) or inactive (“ANALOG”) is
shown in the display area.
In the display area, if a digital audio signal is
detected, the corresponding indicator (Digital 1
through 5) will stop blinking and remain lit. If no digital
audio signal is detected, the indicator will blink.
16. EXT.5.1
Selects the multi-channel output signal from the
DVD player or external decoder source (such as
MPEG, for instance) connected to the 5.1 Ch. input
as the active input. “EXT 5.1” is shown in the Display
Panel when selected. The Ext. 5.1 input can also be
selected through the Input Up/Down buttons (No. 13).
NOTE:
No Ext. 5.1 audio signal is available from head-
phones socket, the Tape, Video 3 and Video 4 out-
puts when the Ext. 5.1. input has been selected.
17. SURROUND MODE
With the Surround Mode buttons the available sur-
round sound modes can be selected. The selected
Surround mode is permanently indicated in the dis-
play area and is also shown for 3 seconds in the
large Star-Burst section of the display. The Surround
Mode buttons scroll through the available surround
sound modes:
With any of the Digital Inputs 1, 2, 3, 4 or 5 select-
ed, the T 761 automatically recognizes if the selected
source carries a Dolby Digital ™ or DTS ™ signal.
When no Dolby Digital or DTS signal is available, the
Surround Mode buttons scrolls through the other
available surround sound modes:
Stereo Pro
Logic Ears Stereo,
etc.
With either Dolby Digital or DTS surround mode
engaged, the Dolby Pro Logic and Ears surround
modes cannot be selected. Dolby Digital and DTS
has six independent channels available in total: Left,
Center, Right, Surround left, Surround Right and an
“Effects Channel” (Subwoofer).
The Dolby Digital signal allows for several channel
configurations.
DTS digital surround is an Encode/Decode system
that currently delivers six discrete channels (5.1) of
“Master-Quality” up to 24-bit audio.
Dolby Pro Logic decodes the center and surround
sound signals embedded in stereo movie sound
tracks from e.g. video, Laser Disc or TV. To decode
correctly, the source must be a Dolby Surround or
Dolby Stereo soundtrack.
In the EARS (Enhanced Ambiance Retrieval
System) Surround Mode, a realistic level of ambience
of surround sound is added to a normal stereo source
such as a CD or FM radio.
NOTES:
Dolby Digital or DTS are only available as a
Surround Mode if the source is either Dolby Digital or
DTS and a Digital Audio input is used.
An external source such as a decoder or DVD play-
er with a decoder built-in (MPEG for instance) can be
connected to the Ext. 5.1 input (No. 16 on the front
panel). When the EXT 5.1 CH. input is selected, no
other surround modes are available.
To obtain the best performance possible it is impor-
tant that the system and all speakers have been set
up correctly. Refer to the chapters “On Screen
Display” and “Setting Up the Surround System”.
18. LEVELS
With the Levels button adjustments can be made to

Right buttons to respectively de-or increase relative
level for selected speaker.
NOTES:
When using Level Adjustment, the “Channel
Balance” On-Screen-Display menu is activated.
Adjustments to the settings are retained in memory
for all surround sound modes.
Only those speakers can be adjusted that have
been selected in the Speaker Settings Menu. For
more information refer also to the chapters “On
Screen Display (OSD) and “Setting up the Surround
System”.
