ZONE CONTROLS
Depending on the settings made at the separate “Zone Setup” menu
under the “Setup Menu” section discussion, Zone 2 can be congured and
managed via this “Zone Controls”window.
Set “Power” to “On”to activate Zone 2. When activated, the Source input for
Zone 2 can be allocated by selecting through the following inputs - Source
1, Source 2, Phono and Local.
As long as the associated Source input is active, it will continuously be
available at ZONE 2 output port in the rear panel regardless of the Main
Zone settings. For example, while the T 778 is at Source 1 mode, you can
set the Zone 2 Controls’“Source”item to“Source 2”; the active Source 2’s
audio output will be directed to ZONE 2 output port in the rear panel even
though the T 778 is at Source 1 mode.
You can then feed ZONE 2 output using applicable connector cables (not
supplied) to another amplier or receiver that maybe located in another
area of your home. With your separate amplier or receiver selecting the
fed signal and with speakers connected, you can then enjoy the zone
selected source’s audio signal.
Select “Local” as your selected Zone 2 Source input if you wish to enjoy the
same source as the main Zone and allow simultaneous listening, but with
full separate volume levels.
If Zone 2 “Power” is set to “O”, it is deactivated or powered o.
ZONE 2 AT AUDIO PREOUT SURROUND BACK
SURR-BL and SURR-BR channels of AUDIO PRE-OUT can be assigned as
Zone 2 OUT. This is applicable only if“Zone 2”is the selected setting of “Back
Amplier” in the “Amplier Setup”menu.
With this condition, the following are applicable
• The surround back amplier channels supply Zone 2 speaker level
output via the surround back speaker terminals. With this setup, Zone
2 audio/speaker level can be increased or decreased using the VOL
(Volume) keys of the supplied ZR 7 zone remote control.
• At the same time, Zone 2 continues to send zone selected audio source
to the corresponding audio input of a separately located additional
amplier or receiver (not supplied) that can power its matching set of
speakers. Zone 2 audio level for this port is xed; it cannot be adjusted
by any ZR 7 volume command.
• Zone 2 audio level can only be adjusted using the Volume keys of ZR 7
remote control only if“Back Amplier” in the “Amplier Setup”menu is
set to “Zone 2”.
IMPORTANT NOTICE
• Only analog audio connected through a Source’s analog audio input
port can be associated as audio source for Zone 2.
• Digital audio sources connected via HDMI, digital optical and digital
coaxial input ports cannot be downmixed and used as Zone 2 audio
source.
• BluOS audio is also not applicable as a Zone 2 audio source.
VOLUME
“Volume”refers to the adjustable secondary Zone 2 Volume level that can
be increased or decreased depending upon its settings. This is applicable
only if the Zone 2 Volume setting in the separate “Zone Setup” menu under
“Setup Menu”is set to“Variable”. If set to “Fixed”, this“Volume” item at
the Zone Controls section will not be available.
NOTES
• If Zone 2 is still ON and STANDBY button is pressed to switch the
front panel display to standby mode, the front panel display will be
extinguished but the STANDBY LED remains illuminated blue. This
indicates that Zone 2 is still active. In order to completely shut down the
front panel display together with Zone 2, press and hold front panel
STANDBY button until the STANDBY LED turns amber.
• Zone 2 is audio only and not associated with any video input sources.

To access and navigate through Setup Menu and its sub-menu selections,
please refer to and follow the directions stated in the sections “DISPLAY THE
OSD” and “NAVIGATING THE OSD AND MAKING CHANGES”.
CONTROL SETUP
The T 778 supports HDMI Control (CEC) and Audio Return Channel (ARC)
functions. Both functions are possible if external devices that also support
both features are interconnected with T 778 via HDMI connection.
AUTO STANDBY
The T 778 can be setup to automatically go to standby mode if the current
Source has no active audio input for 30 minutes.
On: T 778 will go to standby mode automatically if the current Source
has no active audio input for 30 minutes.
O: T 778 remains active even if the current Source has no active audio
input.
CEC/LAN/BluOS IN STANDBY
Status of CEC, LAN and BluOS activity are indicated while the unit is at
standby mode.
On
• Enable CEC feature. Audio and video will continuously stream
from a CEC-enabled HDMI source to a CEC-enabled TV (with both
devices connected via T 778).
• LAN and BluOS connections continue to be active.
O
• T 778 will not pass through any CEC message. Audio and video
will not be streamed from a CEC-enabled HDMI source to a CEC-
enabled TV (with both devices connected via T 778).
• LAN and BluOS connections are idle or inactive.
HDMI CONTROL CEC
Consumer Electronics Control (CEC) is a set of commands that utilizes
HDMI’s two- way communication to allow for single remote control of any
CEC-enabled devices connected with HDMI. A CEC command will trigger
the necessary commands over HDMI for an entire system to auto-congure
itself to respond to the command.
When devices that support HDMI Control (CEC) are connected, the
following modes of operation can be executed via the T 778 or the external
device using any of the device’s remote control.
O: Applies to all CEC options below. At“O” setting, particular CEC feature
is defeated.
Power O: At “On”setting, the T 778 will automatically go to
standby mode if it receives a CEC standby command. On the other
hand, if the T 778 receives a CEC power up command, the T 778 will
correspondingly switch ON from standby mode.
Source Switch: At “On”setting, the T 778 will automatically switch
sources if another CEC device requests a Source change.
For example, if PLAY is pressed on a BD Player with CEC, the T 778
and TV with CEC will automatically switch to their respective input
connections – the T 778 switching to the HDMI input where the BD
Player is connected while the TV will switch to its input where the
T 778’s HDMI OUT is connected. This completes the auto-conguration
– the BD Player is automatically played back using the T 778 and TV.
Audio System: At “On”setting, the T 778 will broadcast a CEC message
indicating it is an active audio system. A CEC compatible TV will usually
mute its audio output when this happens. When this option is enabled,
the T 778 will also respond to CEC volume and mute commands. For
example, a CEC TV may forward the volume commands from its remote
to the T 778.

ARC Mode: Audio Return Channel (ARC) enables an ARC-enabled TV
to send audio data “upstream” to T 778.
This option has three choices: O, Auto or Source Setup.
Auto: When set to Auto, the T 778 will automatically attempt an
ARC audio connection to the TV whenever the TV announces over
CEC that it has become the active source. If an ARC connection can
be established, the T 778 will output the ARC audio signal no matter
what source is selected on the T 778 and will show “HDMI ARC” on
the front panel display. The Auto option tends to work best when
all your devices support CEC and the Source Switch option is set to
“On”.
Source Setup: When set to Source Setup, you can select “ARC” for
the digital audio input in the source setup screen. When you select
a source on the T 778 which is set for ARC, the T 778 will attempt
to initiate an ARC connection with the TV. When using this option,
you would probably also want to make sure Source Switch is o
otherwise other CEC devices may keep changing the T 778 source
when you want it to remain on the ARC source.
IMPORTANT NOTES
• “Audio System” must be set to “On” for “ARC Mode” to be congurable.
• “CEC/LAN/BluOS in Standby” must be set to “On” for audio and video
to continuously stream from a CEC-enabled HDMI source to a CEC-
enabled TV (with both devices connected via T 778).
IR CHANNEL
The T 778 has the capability to operate via alternate IR channel. This is
useful if you have two NAD products that can be operated by similar
remote control commands. With alternate IR Channel, two dierent NAD
products can be controlled independently in the same zone by setting
each one to a dierent IR channel.
IR CHANNEL ASSIGNMENT
The T 778 and the HTR 8 remote control must be set to the same channel.
To change the Main Zone IR Channel on the T 778
• While at “IR Channel” option under “Control Setup”OSD, use HTR 8’s
[D/F] button to select IR Channel “1” or “2”. The default IR Channel is “IR
Channel 0”.
To change the IR Channel on the HTR 8 remote control
• Include a channel number before the library code. For HTR 8, library
code “100” is the default library table for “AMP” device. To select this
“AMP” library table for “IR Channel 0”, retain the library code “100”.
• If you want to load the “AMP”library table on “IR Channel 1”, prex the
library code with “1”to indicate association with“IR Channel 1”. Load
then the “AMP”library table using the code “1100”.
SAMPLE SETUP OF TWO NAD PRODUCTS ON THE SAME ZONE
NAD T 778 and NAD C 368 are both defaulted to IR Channel 0. If [OFF]
button is pressed on the HTR 8 remote control (or SR 9 remote control for
the C 368), both products will go to standby mode. Press [ON] and both
products will power up from standby mode.
To prevent both products from simultaneously going in and out of standby
mode along with other common commands, set each one to a dierent
IR channel. In this setup, we will keep C 368 and SR 9 remote control
defaulted to “IR Channel 0”. As for T 778, we will assign it to“IR Channel 1”;
the same applies to HTR 8.
Set T 778 and HTR 8 to “IR Channel 1” via the following procedure.
T 778
• While at “IR Channel” option under “Control Setup”OSD, use HTR 8’s
[D/F] button to select IR Channel “1”.
HTR 8
Begin by ensuring that the T 778 is powered-up (“on”, not merely in
standby).
• To enter HTR 8’s library mode, press and hold both the [AMP] device
and [A/V PSET] until the LEARN LED turns green.
• While keeping the HTR 8 pointed towards the T 778, enter the library
code “1100”. Press [OFF]. If the T 778 goes to standby mode, press
[ENTER] to accept the library code number and exit library mode.
With both T 778 and HTR 8 set to “IR Channel 1”, the C 368 can now be
remotely controlled independent of the T 778.
NOTE
Performing Factory Reset for T 778 or HTR 8 will restore “IR Channel” to
its factory default setting of “0”.
SOURCE SETUP
The Source Setup menu makes it possible to set, allocate or change the
Sources settings.
The T 778 Sources are all congurable. Each Source can be congured with
respect to the following settings.

ENABLED
One can enable/disable a Source via this option. This is particularly useful if
only few Sources are used. Disabled Sources are skipped over or bypassed
when one swipes through the Sources via the front panel display.
Select “Yes”to enable the particular Source or “No”to disable the Source.
NAME
A new Name maybe assigned to a Source label. For example, if your BD
player is attached to“Source 1”, it is possible to rename “Source 1”to“BD”.
In order to rename the Source label, scroll to the “Name”parameter. Press
[S] to go to the rst character. Then, press [D/F] to pick through the
alphanumeric selections.
Press [S] to move to the next character and at the same time save the
changes done on the current character. The name can be as long as twelve
characters.
The new Name will be shown in the front panel display as well as on the
OSD.
ANALOG AUDIO
The T 778 has three analog audio inputs (Audio 1, Audio 2 and Phono) that
can be variably assigned to each Source.
If “O” is selected, no analog audio signal is selected by the particular
Source.
NOTE
• An incoming digital signal present at the assigned digital input will
always take precedence over the assigned analog audio input, even if
both are present.
• To maintain the analog audio input for the particular Source, select
“O” at the “Digital Audio” setting of the same “Source” menu.
ANALOG GAIN
Gain adjustment allows all sources to play back at the same volume level so
you don’t need to adjust the volume every time a new source is selected. It
is generally preferable to reduce the level of the loudest source rather than
making louder the softer sources.
Scroll to “Analog Gain”, press [S] and then [D/F] to step through the
desired level from -12dB to 12dB.
DIGITAL AUDIO
To take advantage of the T 778’s high performance digital audio circuitry, it
is advisable that the Digital Audio input sources are selected.
There are various types of Digital Audio input for the T 778. These are HDMI,
BluOS, Optical and Coaxial digital input. Another option is“O” whereby no
incoming digital audio signal is selected for the particular Source.
The following are the sets of assignable Digital Audio input:
HDMI $HDMI 1, HDMI 2, HDMI 3, HDMI 4, HDMI 5, HMDI Front
Optical $Optical 1, Optical 2
Coaxial $Coaxial 1, Coaxial 2

NOTE
An incoming digital signal present at the assigned digital input will
always take precedence over the assigned analog audio input, even if
both are present. To maintain the analog audio input for the particular
Source, select “O” at the “Digital Audio” setting of the same “Source”
menu.
VIDEO INPUT
All six HDMI sources can be assigned as video input to a particular Source.
Another option is “O” wherein the particular Source is prompted not to
select any Video input.
HDMI $HDMI 1, HDMI 2, HDMI 3, HDMI 4, HDMI 5, HDMI Front
Previous $Display or retain preceding video.
NOTE
The T 778 also supports HDMI features that include compatibility with a
broad range of 3D and HD digital video sources and displays.
A/V PRESET
A particular Source can be assigned a stored Preset. The parameters set up
in the selected Preset number will be adopted into the particular Source
it is assigned (Refer to the separate section on“A/V Presets”for further
understanding of Preset settings).
If it is desired not to assign the particular Source a Preset setting, select
“None”.
TRIGGER OUT
Trigger Out feature for a particular Source is dependent upon the
congurations done in a separate menu on Trigger Setup (See “Trigger
Setup” below). If “Source Setup”is assigned to all three Trigger output
(Trigger Out 1-3) in the separate “Trigger Setup”menu window, a particular
Source can have the following Trigger Out combinations
Trigger Out: 1 $2 $1 + 2 $3 $1 + 3 $2 + 3 $1+2+ 3
These combinations are dependent upon the assignment of“Source Setup”
for Trigger 1 Out, Trigger 2 Out or Trigger 3 Out at the “Trigger Setup” menu.
Another option is “None”whereby the particular Source is not assigned any
Trigger Out.
For “Trigger Out” to become enabled and assignable at “Source Setup”
menu, make sure to carry out or note the following beforehand
• In the separate “Trigger Setup” menu, assign Trigger 1 Out, Trigger 2 Out
or Trigger 3 Out to “Source Setup.”
• “Trigger Out” will not appear as an option at the Source Setup menu
if at the separate “Trigger Setup”menu, Trigger 1 Out, Trigger 2 Out

SPEAKER SETUP
After connecting all ancillary sources and other combinations, the Speaker
Setup menu will guide you on how to manage and setup your speakers in
order to achieve optimum sound acoustics in your listening environment.
The following are the Speaker Setup Menu sections.
SPEAKER CONFIGURATION
Every surround-sound system requires “bass-management” to direct low-
frequency content from any or all channels to the speakers best able to
reproduce it. For this function to operate correctly, it is important that you
correctly identify your speakers’capabilities. We use the terms “Small” and
“Large” (and “O”) but note that physical size may be irrelevant.
• A “Small” speaker is any model, regardless of physical size, that lacks
signicant deep-bass response, that is, below about 200 Hz.
• A “Large”speaker is any full-range model; that is, one with deep-bass
response
• An “O” speaker is one that is not present in your system. For example,
you might not have any surround-back speakers installed; in that case,
you would set the“Back” setup item to “O”. For“Height” speakers,
selecting “O” option for“Height 1”will automatically cut o both
Height 1 and Height 2 Audio output.
The Speaker Conguration is “global”; that is, it remains in force with all
input and listening modes. However, speaker settings are part of the T 778’s
Preset system. Consequently, multiple speaker settings can be stored for
easy recall as dierent types of recordings or listening modes require.
Speaker Conguration can be managed and adjusted by pressing
a combination of [S] and then [D/F] keys. Set “Front”, “Center” and
“Surround” to “Large”, “Small”(40Hz to 200Hz) or “O” as your subsystem’s
speakers require.
The “Back” speakers can either be “Stereo” or “Mono”speakers. Set
“Subwoofer” to “On”or “O”, selecting “On”only if you have a subwoofer
connected to the T 778’s SUBW1 or SUBW2 output jack. If “Subwoofer” is set
to “O”, “Front” speakers will automatically be set to “Large”.
HEIGHT 1/HEIGHT 2
“Height 1” and “Height 2” AUDIO PRE-OUT can be connected to the audio
input of an external power amplier hooked up with up to 4 Height
speakers. Height1/Height 2 settings must be set to “On” at the “Speaker
Conguration”menu to power up the additional Height speakers.
ENHANCED BASS
“Enhanced Bass”option becomes available when “Front” is set to “Large”.
The Enhanced Bass option allows full range operation of the speakers
with the additional bass contribution of the subwoofer. This feature is
particularly useful when one wants to experience maximum bass output.
Please note that due to acoustic cancellation eects, the bass response
may be uneven when using this setting
You can set Subwoofer to“On”even with “Large” front speakers, in which
case bass content from any channels set to “Small” will be routed to both
the subwoofer and to the front speakers; LFE-channel signal will pass only
to the sub. In most subwoofer-equipped systems, setting front speakers to
“Small” is usually the better option.
All the speakers’low frequency content can be directly adjusted within the
range 40Hz to 200Hz.
NOTE
The congurations set forth at “Speaker Setup” are carried over
whenever it is enabled during A/V Preset setting. Please see also the
section “A/V Presets” for reference.
SPEAKER LEVELS
Adjusting the relative balance of your system’s loudspeakers ensures that
surround-sound recordings, whether music or lm, will present the balance
of eects, music and dialog that the artists intended. Additionally, if your
system incorporates a subwoofer it establishes a correct relationship
between the volume of the subwoofer and the other speakers, and thus of
low-frequencies (bass) to other sonic elements.
USING AN SPL METER
It is quite practical to perform the T 778 level setup routines “by ear,” and
careful work will produce acceptably accurate results. However, the use
of an inexpensive sound-pressure level (SPL) meter, such as Radio Shack
part number 33-2050, makes this task easier, more accurate and more
repeatable. Ownership of such a meter could prove a valuable audio tool.
The SPL meter should be placed at the primary listening position, at
approximately the height of the seated listener’s head. A tripod is helpful
but with a little duct tape almost anything — a pole lamp, music-stand,
or ladder-backed chair, for example — can do as well. Just be sure that no
large acoustically reective surfaces obstruct or are near the microphone
element.
OPERATION
CONFIGURING T 778  SETUP MENU VIA ONSCREEEN DISPLAY

ENGLISH
16
Orient the meter with its microphone (usually at one end) pointing straight
up toward the ceiling (not toward the speakers) and ensure that “C”
weighting scale is selected. Set the meter to display 75 dB SPL. On Radio
Shack meters, this necessitates either setting the meter to its 80 dB range
and taking your readings at the -5 point or selecting the 70 dB range and
reading at the +5 point.
SETTING SPEAKER LEVELS AT TEST MODE
While at “Speaker Levels”menu, press the HTR 8 remote’s [TEST] key
activating the T 778’s Speaker Levels balancing test signal. You will hear
a “surf” sound as you step through your speakers (“Test Mode Active”is
shown besides the Speaker Setup heading), beginning with the Front Left.
If you do not hear the test signal, check your speaker connections or your
“Speaker Conguration” OSD menu settings.
Use the remote’s [D/F] keys to adjust the loudness of the noise output
from the currently playing channel to the required level (it’s usually
simplest to begin with the Front Left). As you cycle the test signal around
the speakers, the OSD will highlight the currently playing channel. The
“level oset” reading on the right will change by 1 dB increments; ±12 dB
adjustment is available. Press [ENTER] to adjust the next speaker.
NOTE
If you are balancing levels “by ear”, choose one speaker—usually the
center—as a reference and adjust each of the others in turn to “sound as
loud” as the reference. Be sure that you remain in the primary listening
position while balancing all channels.
To produce the same SPL meter reading (or subjective loudness), use the
remote’s [D/F] keys to adjust each speaker.
NOTES
• All speakers must be in their nal locations before level-setting.
• Your subwoofer (if any) should be set with its integral crossover
defeated, or if undefeatable, set to its highest-possible frequency if
you are using the T 778’s Subwoofer output. Final subwoofer-level
adjustment “by-ear,” using music and lm sound material, is frequently
useful.
• Due to the eects of room acoustics, matched-pair speakers (front;
surround; back) will not always calibrate to exactly the same level oset
readings.
You can exit“Test” mode at any time by pressing [A] key, bringing you back
to “Speaker Setup”menu. You can also press the [TEST] key to discontinue
the “Test” mode.
SPEAKER DISTANCE
Your system’s speaker distance settings are a subtle but important
renement of your setup. Informing the T 778 of the loudspeaker-to-
listener dimensions of each speaker automatically imposes the correct
delays, optimizing imaging, intelligibility and surround-sound ambience.
Enter your dimensions with precision within about 1 foot (30 cm).
SETTING SPEAKER DISTANCE
While at “Speaker Distance”menu, use the [D/F] keys to individually set
each speaker distance as measured from the principal listening position to
the front surface of the particular speaker. Distance can be displayed as feet
or meters selectable at the “Unit of Measure”item. Distance can be set up to
30 feet or 9.1 meters.
DIRAC LIVE
The proprietary Dirac Live is integrated with your T 778. Dirac Live® is a
patented room correction technology that not only corrects the frequency
response, but also the impulse response of a room’s loudspeakers. Dirac
Live provides true impulse response correction over a large listening area,
improving the depth, positioning and distinction of individual voices and
instruments. Using multiple measurement and mixed phase correction,
Dirac Live helps create a natural, realistic and transparent sound with
tighter bass and reduced room modes, in a way previously not possible.
Initiate Dirac Live by following below Setup Requirements.
T 778
• Update your T 778 to the latest rmware.
• Speaker Conguration must match actual speaker setup – turn o

MICROPHONE
• The supplied measurement microphone can be connected to either
the MIC or USB input of your computer or the USB input of the T 778.
• If the measurement microphone will be connected to the USB
input of your computer or the T 778, ensure that the measurement
microphone, phone jack adapter and USB MIC Sound adapter are all
connected together. The USB MIC Sound adapter is not necessary if the
measurement microphone will be connected to the MIC input of your
computer.
• Minimize external noise such as talking, opening/closing of doors or

ADJUSTING THE VOLUME
In addition to the Volume knob, use the HTR 8’s [VOL D/F] to adjust the
“master volume”of the T 778 raising or lowering the channels altogether. A
momentary keypress will change the master volume by 1 dB increments. If
you hold down [VOL D/F], the master-volume change will “run-on” until
the key is released.
Since recordings vary considerably in overall average level, there is no
imperative to listen at any particular master-volume setting. A setting of -20
dB may sound “as loud”from one CD or BD as -10 dB does from another.
The T 778 will power-up from Standby mode at whatever master volume
setting was last used; however, if the prior setting was greater than –20 dB,
the T 778 will power up at –20 dB. This prevents inadvertently beginning a
session at excessive volume.
MUTING THE SOUND
Use the HTR 8’s [MUTE] key to silence all channels completely. Muting is
always available regardless of the source or listening mode selections.
NOTES
• Changing input or listening-mode selections does not release muting.
• Adjusting the volume level via the HTR 8 or the front panel volume knob
will automatically release the mute function.
ADJUSTING CHANNEL LEVELS “ON THE FLY”
You can make changes to the relative levels of center, surround and
subwoofer outputs without having to go into the “Speaker Levels”menu.
This is very convenient in circumstances like increasing (or tone down)
a lm’s dialog level by raising (lowering) the center channel or reducing
excessive deep bass (or enhance deep bass) by lowering (raising) the
subwoofer level.
Use the HTR 8’s [SURR], [CENT] and [SUB] keys for direct-access level
adjustment of these channels over a range of ±6 dB.
The surround back channels (if any) adjust in lockstep with the surround
channels.
NOTE
Level settings adjusted “On the Fly” are added or subtracted to the setup
levels established at the T 778 level-calibration routine as invoked by the
HTR 8 [TEST] key. However, selecting any Preset will revert the channel
levels to those stored in the preset.
ZONE SETUP
The Zone 2 feature allows one to simultaneously experience in a dierent
zone of the house selected audio from any of the enabled Sources.
VOLUME MODE
Zone 2 have Fixed and Variable volume control. When set to“Variable”and
while at the “Zone Controls”menu OSD, the Zone 2 Volume level can be
adjusted using HTR 8’s [D/F] directly via ZR 7’s [VOL d/f].
On the other hand, if Volume is set to “Fixed”, Zone 2 Volume is set to a
preset dB level and thereafter the Zone’s volume can be varied via the
volume control of the separate amplier it is fed into.
See discussion also about “Zone Controls” at the Main Menu.

AMPLIFIER SETUP
If the surround back speakers are not used in the main zone, their surround
back amplier channels could be assigned for Back, Front (Bi-Amp), Zone 2
and Height 2.
The Surround Back amplier is congurable 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 amplier channel outputs.
Zone 2: Assign the surround back amplier 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 congurable +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/o 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 congurable.
These are provided to reproduce a variety of sound eects depending
upon the content of the source to be played.
LISTENING MODES
The audio format as detected by the selected Source can be automatically
congured 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 congured 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 oers a
broader dynamic, producing magnicent sound quality.

A DTS audio input can be congured relative to its format as follows:
Stereo: If the detected audio is of DTS format, you can default it to one
of the following settings - Neural:X or None
Surround: If the detected audio is of DTS Surround format, you can default
it to one of the following settings - Neural:X, Stereo Downmix or None
None: If “None”is selected, the DTS signal will be defaulted to its native format.
With this setting,“Direct”becomes available as a Listening Mode option.
PCM
PCM (Pulse Code Modulation) is the digital representation of a standard
audio signal converted with little or no compression. If “None”is selected,
the audio signal will be defaulted to its native format.
Stereo: The detected stereo audio format will be congured into one
of the following options - Neural:X, Dolby Surround, Enhanced Stereo,
EARS or None
Surround: The detected surround audio format will be congured
into one of the following options - Neural:X, Dolby Surround, Stereo
Downmix or None
ANALOG
If the audio input is an analog signal, the following are the surround modes
the input can be defaulted - Neural:X, Dolby Surround, Analog Bypass,
Enhanced Stereo, EARS or None
NOTE
Applicable Listening Modes can also be directly selected by repeatedly
pressing HTR 8’s [SURR MODE] button at AMP device mode.
LISTENING MODES
The T 778 oers distinct listening modes, tailored for dierent types of
recording or program material. With a two-channel (Stereo) source, the
following listening modes can be selected.
STEREO
Output is directed to the front left/right channels. Low frequencies are
directed to the subwoofer if one is present in the Speaker settings. Select
“Stereo”when you wish to listen to a stereo (or monaural) production, such
as music CD, without surround enhancement. Stereo recordings whether
in PCM/digital or analog form and whether surround-encoded or not
encoded, are reproduced as recorded. Multi-channel digital recordings
(Dolby Digital and DTS) are reproduced in“Stereo Downmix” mode via the
front left/right channels only as Lt/Rt (left/right-total) signals.
DIRECT
The analog or digital sources are automatically played in their native
formats. All the source’s audio channels are reproduced directly. This
mode recreates the original sound most faithfully thereby producing
outstandingly high quality audio. Note that the source must be at playback
mode for“Direct” to become available as a listening mode option. In order
to automatically playback your source in their native format, implement the
following settings.
1 Go to “Listening Mode Setup”under “Setup Menu”. At the “Listening
Modes”menu, set all Dolby, DTS, PCM and Analog settings to“None”.
With this setup, your source will be played back directly at its native
format.
2 Next, go to “A/V Presets”under “Setup Menu”. At “A/V Presets” menu, set
“Listening Mode Setup”item to “Yes” and then save this setting among
other options, say to“Preset 1”, by selecting “Save Current Setup to
Preset”.
3 Now, you can associate“Preset 1” to any of the“Source”settings. For
example, at Source 1 setting under“Source Setup”, scroll down to “A/V
Preset” item and set it to “Preset 1”. Thus whenever Source 1 is selected,
the associated source will always be directly played back at its native
audio format.
EARS
Two-channel recordings, whether stereo or surround-encoded, are
reproduced with proprietary NAD surround processing with signal output
to the front left/right, center and discrete left/right surround channels,
plus subwoofer (assuming these are present in the current“Speaker
Conguration”). EARS does not employ the surround back speakers (if any).
EARS extracts the natural ambience present in nearly all well-produced
stereo recordings. It does not synthesize any ambience or other sonic
elements and thus remains truer to the sound of the original musical
performance than most other music-surround options.
Select EARS for listening to stereo music recordings and broadcasts.
EARS produces a subtle but highly natural and believable ambience from
nearly all “natural-acoustic” stereo recordings. Typically, these include
classical, jazz, and folk genres as well as numerous examples from others.
Its virtues include realistic, stable “front-stage”sonic imaging and spacious
but unexaggerated ambient “virtual acoustics”that remain faithful to the
original recording.
ENHANCED STEREO
All recordings are reproduced in stereo via the maximum speaker
complement congured in the current“Speaker Conguration”. Enhanced
stereo can be useful for maximum volume from all channels or for multi-
speaker background music (cocktail party) listening. For this mode, Front,
Center, Surround and Back speakers can be turned ON/OFF as desired.
ANALOG BYPASS
All analog signals remain in the analog domain without analog-to-digital
conversions. At Analog Bypass, the DSP circuitry is bypassed but full tone
control functions remain. “Bass management” or Speaker settings are also
not in eect as these are DSP functions.
DOLBY ATMOS
Dolby Atmos redenes your entertainment experience. Overhead
dimension is added by creating a full audio atmosphere and realistically
depicting objects moving overhead. Sound from a helicopter, a car
screeching around a corner or a melodic bird call can be precisely placed
and moved anywhere in your room, including overhead, to ow above
and around you in three-dimensional space. Dolby Atmos also renders
everything from dialogue to quiet scenes to whirlwind action with
astonishing clarity, richness, detail and depth.
DTS:X
DTS:X places sound where it would occur naturally in space, creating the
most lifelike, multi-dimensional audio experience ever. DTS:X technology
adapts to the viewing environment, allowing for a exible speaker
conguration that best ts the viewing space. Through the use of object-
based audio, DTS:X technology is able to scale immersive soundtrack
presentations across a wide range of playback systems, from ecient to
extravagant, while staying true to the content creator’s vision.
Neural:X
Neural:X™ is the latest spatial remapping engine from DTS, enabling an
immersive, multidimensional experience from legacy content. It is included
inside of DTS:X to provide upmix of Neural:X-encoded and non-encoded
(PCM) data. With DTS Neural:X, stereo, 5.1 or 7.1 content can be upmixed to
take full advantage of all speakers in your surround sound system.

DOLBY SETUP
Dynamic Range Control: You can select the eective dynamic range
(subjective range from soft to loud) for playback of Dolby Digital
soundtracks. For fully cinematic eect, always select 100%. 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.
For Dolby TrueHD sources, set the Dynamic Range Control to “Auto”.
Center Spread: Center image is spread into the Left and Right speakers.
It is designed to complement musical content or to spread the dialogue
more evenly across a wide screen display.
On: Center Spread function is enabled.
O: Center Spread function is disabled.
DTS SETUP
Dynamic range control and dialog content can be congured at DTS Setup
menu.
Dynamic Range Control: This is the same congurable Dynamic
Range Control feature as described above at Dolby Setup, the only
dierence being the soundtrack is now in DTS format.
Dialog Control: Dialog levels are adjusted. Dialog control is more
than just adjusting center channel level as the center channel may also
contain other sound elements that get raised or lowered along with
the dialog.
NOTE
Dialog control applies only for playback of DTS:X content that supports
DTS Dialogue Control feature.
ENHANCED STEREO
Please refer to the same description of ENHANCED STEREO under
“LISTENING MODES”.
FRONT PANEL DISPLAY SETUP
The front panel display and On-Screen Display (OSD) can be shown in
various ways by navigating through the parameters at the Front Panel
Display Setup menu.
NOTE
The congurations set forth at “Front Panel Display Setup” are carried
over whenever it is enabled during A/V Presets setting. Please see also
the section below about “A/V Presets”.
Brightness function makes it possible to adjust the brightness level of the
front panel display.
Bright: Display is at its brightest level or above normal brightness level.
Normal: Display brightness level is normal.
Dim: Display is dimmed or below normal brightness level.
Temporary Display feature enables the display to be turned o
temporarily after a period of non-user interface.
Temp: Display is turned o temporarily after 30 seconds of non-
user interface (or right after user interface). Standby LED remained
illuminated blue. Display is activated once user interface is initiated.
On: Display remains illuminated.
