CONFIGURING T 778 - SETUP MENU VIA ON-SCREEEN DISPLAY

AMPLIFIER SETUP

If the surround back speakers are not used in the main zone, their surround
back amplifier channels could be assigned for Back, Front (Bi-Amp), Zone 2
and Height 2.
The Surround Back amplifier is configurable through the following settings
Back: Assign as surround back speakers.
Front (Bi-Amp): Provide a bi-amp mode for the Main Front speakers
(Left and Right) speakers thus reproducing the Front Left and Front
Right amplifier channel outputs.
Zone 2: Assign the surround back amplifier channels to supply Zone 2
speaker level outputs from the surround back speaker terminals. Refer
also to the item about "ZONE 2 AT AUDIO PRE-OUT SURROUND BACK"
in the "ZONE CONTROLS" segment of the "OPERATION - CONFIGURING
T 778 - MAIN MENU VIA ON-SCREEN DISPLAY" section.
Height 2: Assign as Height 2 speakers.

TRIGGER SETUP

T 778 features three configurable +12V DC Trigger Output that can be
used to activate a component or system it is fed into. A Trigger Input is also
available to turn on the applicable link it is associated to.
TRIGGER OUT
Triggers are low voltage signals used to turn on/off other compliant
devices. T 778's three +12V DC Trigger Outputs (Trigger 1 Out, Trigger 2 Out
and Trigger 3 Out) are dependent upon the mode they are associated with.
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 T 778 is at
powered state.
Zone 2: When Zone 2 is at powered state, +12V DC is available at the
assigned 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. Please see also separate discussion about "Trigger Out" under
the Source Setup section.
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.

AUTO TRIGGER IN
Auto Trigger IN allows external system controllers to toggle the associated
section of the T 778 from "Standby" to "On" and vice versa.
Main: From standby mode, the T 778 is powered ON when +12V DC is
applied at Trigger IN.
Zone 2: Zone 2 is turned ON whenever +12V DC is present at Trigger IN.
All: Main and Zone 2 as described above will all be activated given
+12V DC input at Trigger IN.

LISTENING MODE SETUP

The T 778 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 MODES
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 Dolby Digital (double-D symbol) logo
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 as follows:
Stereo: If the detected audio is of Dolby stereo format, you can default
it to either Dolby Surround or None.
Surround: If the detected audio is of Dolby Surround format, you can
default it to one of the following settings - Dolby Surround, Stereo
Downmix or None
None: If "None" is selected, the Dolby Digital signal will be defaulted
to its native format. With this setting, "Direct" becomes available as a
Listening Mode option.
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 5.1 channel 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.
