AMPLIFIER SETUP

If the surround back speakers are not used in the main zone, their surround
back amplifier channels could be assigned for Main Back or Zone 2.
The Surround Back amplifier is configurable through the following settings
• Main Back: Assign as surround back speakers.
• Zone 2: Assign the surround back amplifier channels to supply Zone 2
speaker level outputs from the surround back speaker terminals.
IMPORTANT NOTICE
If "Back Amp" is set to Zone 2, it is not possible to select "7.1" in the Auto
Calibration menu since the surround back speakers are effectively not included
in the configuration anymore. Only "5.1" is selectable at this condition.

TRIGGER SETUP

The T 747 features a configurable +12V DC Trigger Output that can be used
to activate a component or system it is fed into.
TRIGGER OUT
Triggers are low voltage signals used to turn on/off other compliant
devices. There are three choices where +12V DC output can be assigned
and these are – Main, Zone 2 and Source Setup.
Main: +12V DC is available at the assigned Trigger Out when the T 747
is at powered state.
zone 2: When the Zone 2 is at powered state, +12V DC is available at
Trigger Out.
Source Setup: If Trigger Output is linked to "Source Setup", +12V DC
is available at Trigger Out whenever the particularly assigned Source is
selected.
DELAY
The availability of +12V DC at Trigger OUT can be regulated. If it is desired
that +12V DC is available without delay the moment Trigger OUT is linked
to its assigned setting, set Delay to 0s. Otherwise, one can select through a
delay time of 1s to 15s.

LISTENING MODE SETUP

The T 747 has various listening mode options and is mostly configurable.
These are provided to reproduce a variety of sound effects depending
upon the content of the source to be played.

LISTENING MODE

The audio format as detected by the selected Source can be automatically
configured and processed through the following options:
Dolby Digital
Dolby Digital is the multi-channel digital signal format developed in the
Dolby laboratories. Discs bearing the double-D symbol were recorded with
up to 5.1 channels of digital signals, reproducing a much better sound
quality, with dynamic and spatial sound sensations that are much better
than in the previous Dolby Surround.
A Dolby Digital audio input can be configured relative to its format.
2 Channel: If the detected audio is a 2 Channel Dolby Digital signal,
you can default it to one of the following settings – PLIIx Movie, PLIIx
Music, DVS Wide, DVS Reference or None.
Surround: If the detected audio is a Surround Dolby Digital signal, you can
default it to one of the following settings –Dolby Digital EX, PLIIx Movie,
PLIIx Music, DVS Wide, DVS Reference, Stereo Downmix or None.
None: If "None" is selected, the Dolby Digital format will follow the
"Digital" setting set forth at "Other" option under this menu section. See
discussion below about "OTHER".
