80W x 7ch Amplifier (all channels driven): The power rating
of 80 watts
(continuous) x 7 is taken with all channels driven simultaneously into a 4Ω or
8Ω load, from 20Hz to 20kHz, at the rated distortion of 0.03% THD. The T 777
provides a dynamic power of 160W/ch into 8Ω and 260W/ch into 4Ω.
Amplifier Assignment: The T 777 supports up to 7.2 channels (Front
L/R, Center, Surround L/R, Surround Back L/R, and Dual SW) for surround playback
defined by the Blu-ray disc format. The seven amplifier channels built into the
receiver are typically used for 7.2 channel surround in the main room, but there
are various amplifier configurations to accommodate your home theater setup:
- 7.2ch: The T 777 provides 7.2ch surround (with front left/right,
center-channel, surround left/right, and surround back left/right channels
along with dual preamp subwoofer outputs) in your main zone.
- Bi-Amp: You can configure the amplifier for front bi-amp
operation to achieve a higher-quality 2-channel sound by connecting the
receiver's front and surround back channels to your main front speakers (if
compatible). In this configuration, the receiver will be limited to 5.2ch
- Multi-Zone: The surround back channel amplifier can also be
assigned to power stereo speakers in either Zone 2, Zone 3, or Zone 4 (only
one Zone can be powered). The receiver will be limited to 5.2ch surround in
the main zone.
NAD's Full Disclosure Power Ratings: NAD uses Full
Disclosure Power (FDP), the most demanding criterion for performance
measurement. FDP specifies distortion under the most extreme conditions of low
impedance loads and frequency extremes, rather than the simple and easy 1kHz @ 8
ohms test quoted by many of other manufactures. NAD uses this stricter
performance criterion because it more closely matches the demands of real music
and real loudspeakers. Maintaining specified distortion at 4/8Ω and at 20-20kHz
is a much more difficult achievement. The benefit of NAD's Full Disclosure Power
is the total elimination of audible distortion at any listening level. This
provides pinpoint imaging and realism with music and movies alike.
PowerDrive Amplifier Technology: The T 777 uses NAD's
proprietary PowerDrive amplifier technology that provides high dynamic power and
low impedance drive capability. By adding a second high-voltage rail to the
amp's well regulated high-current power supply, the amplifier can nearly double
its continuous power on a short term dynamic power basis. This uniquely
efficient power supply topology provides the real world benefits of high dynamic
power that remains uncompromised by low impedance speakers.
The PowerDrive topology allows the T 777 to
deliver maximum performance under virtually any circumstance, independent of
the loudspeakers it is driving. The circuitry automatically senses the impedance
characteristics of the loudspeaker and will then adjust its power supply
settings to best cope with that specific load. PowerDrive topology is a
practical approach to enable an amplifier to easily deal with musical dynamics
and difficult speaker loads. PowerDrive not only makes NAD amplifiers
sound better, it makes them cooler running, with improved efficiency, leading to
greater reliability as well
24-Bit/192kHz Burr-Brown DAC: The NAD T 777 AV Surround Sound Receiver employs a carefully selected, top-level 24-bit/192kHz Burr Brown DAC for
the ultimate audiophile performance.
MDC (Modular Design Construction): MDC ends the frustration of having to replace
your entire AV surround sound receiver just to keep pace with the ever-changing world
of AV electronics. NAD's most important recent innovation, MDC battles
technology obsolescence by allowing you to upgrade the T 777 with new
connectivity and features as new technology becomes available. MDC places all the input circuitry on easily removable plug-in cards; your investment
is protected because a single card, rather than the entire receiver, can be
replaced when a new format is introduced.
NAD Soft Clipping: The T 777 incorporates NAD's unique
Soft-Clipping circuitry in all seven channels. Any amplifier can be overdriven
if it is played too loud, exceeding the maximum output power. Under such
circumstances, amplifiers produce extreme high levels of distortion which,
besides sounding very unpleasant, can damage your loudspeakers. The Soft
Clipping circuit suppresses such distortion and minimizes the risk of damage to
speakers. This is particularly important with movie soundtracks which often
contain very dynamic outbursts in which, unlike music, it is difficult to hear
this potentially damaging distortion. The Soft Clipping LED on the front panel
illuminates when the Soft Clipping circuit is engaged. Soft Clipping can be
defeated with a rear panel switch.
Audyssey Technology: The NAD T 777 features a full package
of Audyssey audio technologies for optimal sound quality.
- Audyssey MultEQ XT Speaker Calibration: Speaker set up is a snap using a supplied
calibration microphone and Audyssey MultEQ XT room correction with custom NAD
target response curves for the optimal level of performance. Using the supplied
microphone, Audyssey Auto Setup performs all speaker settings. The receiver
automatically checks what speakers are connected (5.1ch vs. 7.1ch) and their
polarity, measures and adjusts each speaker's distance (delay time), relative
level (volume), and size (crossover point). NAD's
proprietarily enhanced Audyssey MultEQ XT technology enables your home theater
to sound the way it was intended in every seat by removing the distortion caused
by room acoustics. Audyssey MultEQ XT can be set to the following levels. Your connected speakers can also be adjusted manually
through the T 777's menus system if you prefer.
- Audyssey: Audyssey developed target curve.
- Flat: This setting is appropriate for very small or highly
treated rooms in which the listener is seated quite close to the
loudspeakers. MultEQ XT filters are used in the same way as the Audyssey curve,
but it does not apply a high frequency roll-off.
- NAD: Ideal "in room" response developed by NAD engineers along
with Audyssey Engineers.
- Off: MultEQ filters are not used or no measurement process at
- Audyssey Dynamic EQ: Audyssey Dynamic EQ solves the problem of
deteriorating sound quality as volume is decreased by taking into account human
perception and room acoustics. By carefully combining information from incoming
source levels with actual output sound levels in the room, Audyssey Dynamic EQ
delivers unprecedented sound reproduction at all volume levels. Adding a Volume Offset will have the effect of reducing the
amount of boost applied by Dynamic EQ, for any given volume setting. As a
consequence, the amount of overall digital attenuation required is also
- Audyssey Dynamic Volume: Audyssey Dynamic Volume delivers consistent
volume playback levels, anticipating sudden spikes and dips in volume and
compensating for them in real time. Audyssey Dynamic Volume monitors the volume
of program material moment-by-moment, maintaining the desired listening level
for all content while optimizing the dynamic range to preserve the impact. Audyssey Dynamic Volume includes Audyssey Dynamic EQ. These
two technologies enable the full frequency response of the source at its
original level to be reproduced at any listening level. Even at lower
listening volumes, Dynamic Volume ensures that the richness and dynamics of
the response are maintained.
Dual Core Floating Point DSP Technology: The T 777 uses the
latest high-speed Dual Core Floating Point DSP technology for popular surround
formats including Dolby Digital, Dolby TrueHD, Dolby Digital Plus, DTS, and
DTS-HD Master Audio.
- Dolby Digital:
Dolby, Digital EX,
Dolby Digital Plus,
DTS-HD Master Audio,
DTS-HD High Resolution,
DTS Neo: 6
- Dolby Pro Logic:
Dolby Pro Logic II,
Dolby Pro Logic IIx
Note: Dolby Digital and DTS listening modes can only be
selected if your audio source is connected to the A/V receiver via a digital
audio connection (HDMI, optical, or coaxial). To enjoy true 7.1ch Dolby
Digital TrueHD and DTS-HD surround sound, the receiver must be connected to
your Blu-ray player via HDMI.
Listening Mode Parameters: The T 777 provides the following Listening
Mode Parameter adjustments for Dolby Pro Logic IIx and DTS NEO:6.
- Center Width (DPL IIx): Modifies the "hard-centeredness" of the
center image, by gradually mixing mono center content to the Front
left/right speakers as well. A setting of 0 retains the center-channel-only
default while a setting of 7 yields a fully phantom center channel.
- Dimension (DPL IIx): Adjusts front-rear emphasis of the surround
effect independently from the relative channel levels.
- Panorama (DPL IIx): Adds a "wraparound" effect by extending some
stereo content into the surround channels.
- Center Gain (DTS NEO:6): Adjust for better center image in
relation to the surround sound channels.
EARS: Two-channel recordings, whether stereo or
surround-encoded, are reproduced with proprietary NAD surround processing with
signals output to the front left/right, center and discrete left/right surround
channels, plus subwoofer. 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. EARS offers realistic,
stable "front-stage" sonic imaging and spacious but unexaggerated ambient
"virtual acoustics" that remain faithful to the original recording. 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 genre.
Stereo Modes: The NAD T 777 also provides two-channel stereo
and multi-channel stereo playback, as well as an analog bypass stereo mode.
- Stereo: All 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 or FM broadcast, 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.
- Enhanced Stereo: All recordings are reproduced in
stereo via the maximum speaker complement. 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 effect as these are DSP
Direct Mode: 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.
Tone Controls: The T 777 has three Tone Control levels; Treble, Bass,
Center Dialog. Bass and Treble controls only affect the low bass and high treble
leaving the critical midrange frequencies free of coloration. The Center Dialog
control boosts the 'presence' of the midrange region improving intelligibility
Note: Tone Defeat gives one the choice of varying or completely
bypassing the tone control section of the T 777.
Enhanced Bass: When the subwoofer is set to 'On' and your front
speakers set to 'Large', the option 'Enhanced Bass' becomes available. Normally,
with speakers set to 'Large' the subwoofer is not active. 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.
Note: Please note that due to acoustic cancellation effects, the
bass response may be uneven when using this setting.
Gain Adjustment: 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.
Dynamic Range Control: You can select the effective dynamic range
(subjective range from soft to loud) for playback of Dolby Digital soundtracks.
For fully cinematic effect, always select 100% (the default). Settings of 75%,
50%, and 25% progressively reduce dynamic range, making soft sounds
comparatively louder while limiting the peak loudness of loud ones.
Audio Inputs/Outputs: The NAD T 777 offers a variety of
analog and digital audio inputs/outputs.
- Digital Inputs/Outputs: There are three coaxial digital
inputs and three optical digital inputs. The inputs accept digital audio signals
from a digital TV, Set top box, Blu-ray player, compact disc, DVD, LD, or other
digital source components; each can be assigned to a specific source using the
on-screen menu. There are also digital outputs; one coaxial and one optical. The
digital outputs can be connected to MD recorders, CD recorders, DAT decks, or
other similar components.
- 5-Way Binding Posts: The nine pair of gold-plated binding
post speaker terminals (Front A left/right, Front B left/right, Center, Surround left/right, and
Surround Back left/right) will accept banana plugs (single only), pin
connectors, and bare wire (up to 10 gauge). The receiver supports A-B front
speakers and Bi-amping of Front A speaker.
- A-B Speakers: The T 777 offers Front A and Front B
speakers. These speaker connections are wired in parallel inside the
receiver. You can connect 4Ω speakers, if you are only going to drive one
pair of speakers (A or B) at a time. You will need to connect 8Ω speakers,
if you are going to drive Front A and Front B speakers simultaneously.
- Bi-Amping Front Speakers: The Surround-Back speaker
terminals can be reassigned and used along with the Front terminals to
bi-amp the front speakers, providing improved bass and treble performance.
When bi-amping the front speakers the receiver is limited to a 5.2ch speaker
system in the main room.
- 7.1 Channel Input: The T 777 features a 7.1 Channel input
(Front left, Front right, Center, Surround left, Surround right, Surround Back
left, Surround Back right, and Subwoofer) for connecting an outboard processor
or multi-channel analog source. The 7.1 channel input can be assigned to eight
of the nine inputs (source 5 is fixed).
- 7.2ch Preamp Outputs: The T 777 features Front left, Front right,
Center, Surround left, Surround right, Surround Back left, Surround Back right
and dual Subwoofer preamp outputs to connect the receiver to external power
amplifiers. There is also a dedicated stereo output for Zone 2.
- Headphone Output: The receiver features a 1/4" stereo
headphone jack on the front-panel for connecting an optional pair of headphones.
The unit's speaker outputs are automatically muted when a set of headphones is
- Auxiliary Input: There is a 3.5mm stereo mini-jack input on the
front-panel for connecting a portable digital audio player.
Video Inputs/Outputs: The NAD T 777 is fitted with seven HDMI inputs/two
HDMI outputs, three component video inputs/one component video output, four
composite video inputs and four S-video inputs. All video inputs are
- HDMI: This unit has seven HDMI inputs (6 rear/1
front) and two HDMI
outputs. The inputs are assignable using the receiver's on-screen menu. The T
187 will convert composite video, S-video, and component video to HDMI. The
two HDMI outputs are parallel so the same video signal is output through
both and can be used simultaneously. The HDMI inputs/outputs can accept up
- Component: This unit has three component video inputs
and one component video output. These inputs are also assignable using the
receiver's on-screen menu. The component video inputs/outputs will accept up
- Composite: There are four composite video inputs (3
rear/1 front); the inputs are
assigned to specific sources using the on-screen menu. The composite video
inputs will accept up to 480i.
- S-Video Input: There are four S-video inputs (3 rear/1
front); the inputs are assigned to specific sources using the on-screen
menu. The S-video inputs will accept up to 480i.
Analog to HDMI Video Conversion: Analog video sources (such as
composite, component, and S-video) are converted to HDMI for simple one 'one-wire'
connection to HDMI equipped TVs. The T 777 does not offer video upscaling; all
video processing will be done via your connected television.
3D Ready: The NAD T 777 supports 3D HDMI pass-through from
connected 3D-compatible Blu-ray, games and broadcast devices to 3D-compatible
HDTVs (all 3D components must be connected via HDMI 1.4). 3D provides a more
engaging audio and video consumer experience. Note that special eyewear may be
required for viewing 3D content.
Lip Sync Delay: Video signals may take longer to process
than audio signals, depending on the connected video equipment. The audio signal
can be delayed up to 120ms to synchronize with the video signal.
Audio Return Channel (ARC): If the connected TV has HDMI
version 1.4 and supports ARC, the audio signal can be transferred from the TV
(when its internal tuner is used) to the T 777 through a single HDMI cable, so a
second cable isn't needed.
HDMI Pass-through: When the T 777 is in standby
mode (power off), the HDMI source signals will continuously pass
through the receiver to the TV. The HDMI Control (CEC) feature must be enabled in order for HDMI Pass-through to work.
AM/FM Tuner: The NAD T 777 features an internal AM/FM tuner that
offers high-quality sound from your local radio broadcasts. The unit includes an
external AM loop antenna, and external ribbon-wire FM antenna.
RDS: The Radio Data System (RDS) permits sending small amounts of
digital information using conventional FM radio broadcasts. The T 777 supports
two RDS modes; Program-Service Name (PS mode) and Radio-Text (RT mode). Not
every FM station incorporates RDS in its broadcast signal. In most areas you
will find from one to several RDS-enabled stations, but it is by no means
impossible that your favorite stations will not be broadcasting RDS data.
Direct Tuning: If you know your desired station's frequency
allocation, you can tune directly to the station using the included IR remote
Presets: The T 777 can store a mix of your 40 favorite AM, FM and XM
radio stations for immediate recall. A twelve character name can be assigned to
each AM/FM station preset.
OSD (On-Screen Display): In addition to the unit's front-panel
display, the T 777 employs a simple, self-explanatory
on-screen display menus system which will appear on your connected television.
Zone 2/3/4: The T 777 has three configurable Zones; Zone 2, Zone 3, and Zone
4. Each Zone consists of stereo RCA line-level output to connect an external
receiver or integrated amp in other rooms of your home, allowing you to
listen to 7.2ch surround in the Main Zone and 2ch stereo of a different audio
source in other rooms of your home. The AV receivers surround back
channels can also be configured to power a pair of speakers in either Zone 2,
Zone 3, or Zone 4 (only one Zone can be powered). By powering an additional
zone, the main zone will be limited to 5.2ch surround. The volume of Zone 2/3/4 can
be controlled by the NAD receiver using either configuration or from your add-on
integrated amplifier when using the line-output.
- Compatible Zone Sources: Only tuner and analog audio sources can be
sent to Zone 2, 3, and 4.
- Incompatible Zone Sources: HDMI, optical, and coaxial digital audio
cannot be passed through Zone 2, 3, or 4. Video cannot be sent to Zone 2, 3, or
Note: Each Zone allows independent source and volume control, with a simplified second-zone remote
Source Configuration: The T 777 is equipped with ten configurable
Sources. A particular Source can be enabled or disabled, renamed, assigned
analog and digital audio sources, video sources, A/V Presets, Trigger settings,
among other settings.
A/V Preset: The T 777's 'A/V Presets' allow you to customize your
audio-video playback, and recall them with a single key-press. The parameters
'Listening Mode', 'DSP Options' and 'Tone Controls', together with 'Speaker
Setup' and 'Display Setup' are stored together as a single A/V Preset. You may
create one A/V Preset optimized for pop music and another for classical. One
more A/V Preset can be set up to recall each family member's favorite setting or
one for fully cinematic home-theater playback, and yet another one for
late-night movies; with each A/V Preset fine-tuned to a particular scenario or
Sleep Mode: The Sleep Mode timer will switch the T 777 to Standby mode
automatically after a preset number of minutes (15-90 min.).
Protection Circuits: This AV receiver utilizes a combination
of fuse and electronic nonintrusive protection. Each channel is fully protected
against excess temperature, DC fault, and, loudspeaker short-circuit.
Main Remote: The HTR 8 IR remote controls the T 777 and is
pre-coded with controls for other NAD components. The IR remote also features a
"learning function" which allows you to teach commands to the HTR 8 from another
remote controller, regardless of brand. The HTR 8's key-illumination can be set
to remain lit for 0-9 seconds. A 'macro' command is a series of two or more
remote codes issued automatically from a single key-press. The HTR 8 can store
one macro on each of its function keys.
Zone 2 Remote: The included ZR 7 is a discrete compact
IR remote for controlling the Zone 2 features of the T 777; it allows control of
the Zone 2 volume and source selection, as well as other applicable functions.
The ZR 7 will work from a different room using an IR sensor and hub or the IR
sensor of a compatible NAD component in the second zone (either must be wired
back to the location of the T 777).
Note: The ZR 7 remote control will only control Zone 2
applications. Zone 3 and Zone 4 can be configured and managed at the
appropriate Zone OSD menu using the T 777's front-panel navigations buttons,
as well as the corresponding keys on the HTR 8 remote control.
HDMI CEC (Consumer Electronic Control): 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-configure itself to respond to the command.
- Power: The T 777 will automatically go to standby mode if it
receives a CEC standby command. On the other hand, if the T 777 receives a
CEC power up command, the T 777 will correspondingly switch ON from standby
- Source Switch: The T 777 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 777 and TV with CEC will
automatically switch to their respective input connections; the T 777
switching to the HDMI input where the BD Player is connected while the TV
will switch to its input where the T 777's HDMI Monitor Out is connected.
- Audio System: The T 777 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 777 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 777.
Remote Connections: The NAD T 777 is fitted with the
following custom remote inputs/outputs.
- +12V Trigger Outputs/Input: The three +12V trigger outputs (3.5mm)
let you turn on/off other devices along with the T 777. The +12V trigger input
lets you turn on/off the T 777 from another device.
- IR Input/Outputs: There is an IR input (3.5mm), used to
control this unit using an optional infrared repeater or the IR output of
another component. There are also three IR outputs (3.5mm) used to control
another compatible component.
- RS-232 Port: The rear-panel RS-232 port allows connection to
a compatible PC or external whole-house control system from companies such as
AMX or Crestron. NAD is a certified partner of AMX and Crestron and fully
supports these external devices.
Ethernet Port: The T 777 is fitted with a Ethernet Port (RJ-45) to
connect to your home network for IP control. With your PC and the T 777 on the
same network, it allows remote control of the T 777 via compatible external
Switched AC Outlet: This convenient 3-prong outlet can
supply switched AC power to another component or accessory. The total draw off
all devices connected to this outlet must not exceed 120 watts.
NAD A/V Remote App: This device can be controlled by your
iPhone or iPad by the NAD A/V Remote App. Through the app, you can select
and control basic functions such as power, volume, source, and listening mode
for all zones. You can also name sources, tweak receiver presets, adjust tone
controls and trim levels, tune radio stations, and activate Audyssey room
equalization, from anywhere in the house. The NAD A/V Remote App is available
from Apple iTunes, and works with iPhone, iPad, and iPod touch running iOS 5.1.1
