Amplifier Section: The T 757 is rated using NAD's Full
Disclosure Power; 60 watts continuous output x 7 channels with all channels
running simultaneously from 20-20,000 Hz into 8Ω loads with no more than
0.08% THD. The stereo output is 110 watts continuous x 2 channels under the
Amplifier Assignment: The T 757 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
- 7.1ch: The T 757 provides 7.2ch surround (with front
left/right, center-channel, surround left/right, and surround back
left/right channels along with a preamp subwoofer output) in your main
- 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
- Multi-Zone: The surround back channel amplifier can
also be assigned to power stereo speakers in Zone 2. The receiver will be
limited to 5.2ch surround in the main zone.
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
757 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.
Audyssey Auto Calibration: The Audyssey auto setup and
calibration feature uses the included microphone, along with sophisticated
digital electronics to automatically setup and calibrate the T 757 to the
exact speakers and speaker placement of your unique home theater. The receiver
automatically checks what speakers are connected (5.1 vs 7.1) and their polarity,
measures and adjusts each speaker's distance (delay time), relative level (volume),
and size (crossover point). The speakers can also be adjusted manually if you
Listening Modes: The T 757 offers decoding for all the
latest surround formats including Dolby Digital, Dolby TrueHD, Dolby Digital
Plus, DTS, and DTS-HD Master Audio; as well as Dolby Pro Logic surround
- 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 757 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
- 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 757 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.
A/V Presets: Five A/V presets can be stored with customized
settings for listening mode, DSP options (lip sync delay), tone control,
speaker setup, and front panel display.
Tone Controls: Bass and treble can be adjusted +/- 10 dB.
Audio Inputs/Outputs: The NAD T 757 offers a variety of
analog and digital audio inputs/outputs.
- Assignable Inputs: Eight of the T 757's nine inputs are
assignable (source 5 is fixed as analog audio 3 and S-video 1); you can program the
name (as displayed on the front panel and OSD, up to twelve characters), analog
input, gain setting (+/-12 dB to match the other sources), digital audio input,
and video input to match a given source selection.
- Digital Inputs/Outputs: There are three coaxial digital inputs
and four optical digital inputs (one front). 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.
- Preamp Outputs: The T 757 features Front left, Front right,
Center, Surround left, Surround right, Surround Back left, Surround Back right
and Subwoofer preamp outputs to connect the receiver to external power amplifiers.
There is also a dedicated stereo output for Zone 2.
- 7.1 Channel Input: The T 757 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).
- Speaker Terminals: The receiver has binding post speaker
terminals for the front, center, surround, and surround back channels. The
binding posts can accept bare wire up to 12 gauge, pin connectors, and single
banana plugs. The terminals are spaced too far apart for dual banana plugs and
a collar surrounding the terminals prevents the use of spade connectors.
- 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
Multi-Zone: The T 757's Zone 2 output allows independent
selection and control of output to another room. There are dedicated stereo
RCA audio outputs for Zone 2. If no surround back speakers are used in the
main zone, the surround back amplifier channels can be reassigned to power
speakers in Zone 2. The volume of Zone 2 can be controlled by the NAD receiver
using either configuration or from your add-on integrated amplifier when using
the line-output. Optical/coaxial digital and HDMI audio sources are not
output to Zone 2. You cannot output any video signal to Zone 2.
HDMI 1.4 Inputs/Output: This unit has four HDMI (1.4) inputs and one
HDMI (1.4) output. The inputs are assignable using the receiver's on-screen menu. The
T 757 will convert composite video, S-video, and component video to HDMI.
Video Conversion: The T 757 takes each analog video input
(composite video, S-video, or component video), digitizes it and sends it out
through all of the monitor outputs (analog and HDMI). The on screen display is
also output through all of the monitor outputs.
3D Pass-Through: With the advent of 3D media, it is
important to own a receiver that recognizes 3D video signals. The T 757 is able
to pass through 3D signals from your Blu-ray player, ensuring that the 3D effect
doesn't get lost in translation. It also recognizes signals from 3D television
broadcasts. By connecting a 3D-compliant Blu-ray disc player and 3D-compliant TV
to the T 757, you will have a 3D home theater where you can enjoy
high-definition sound and video on a level you've never experienced before.
ARC (Audio Return Channel): This feature allows audio to be
sent from your compatible HDTV to your receiver through the same HDMI cable
already being used to send audio and video to your HDTV. This eliminates the
need for extra cables connected to your television.
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.
Component Video Inputs/Output: This unit has three component
video inputs and one component video output. These inputs are also assignable using
the receiver's on-screen menu and the composite video and S-video input signals are
converted to component video.
Composite Video Inputs/Output: There are three composite
video inputs (one front, two rear) and one composite video monitor output; the
inputs are assigned to specific sources using the on-screen menu.
Front-Panel A/V Input: The receiver features a front-panel
A/V input which consists of composite video, stereo RCA, and optical
digital jacks. There is also a 3.5mm stereo mini-jack input on the front panel.
Main Remote: The AVR 4 remote controls the T 757 and is
pre-coded with controls for other NAD components.
Zone 2 Remote: The included ZR 5 is a discrete compact
remote for controlling the Zone 2 features of the T 757, it allows control
of the Zone 2 volume and source selection, as well as other applicable functions.
The ZR 5 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 757).
HDMI Control: The NAD T 757 can control select external
audio/video components connected via HDMI which support HDMI control. When you
make an HDMI connection with a TV or player compatible with the T 7575's HDMI
control function, you can perform the operations from the T 757's remote
control; Power off, Switching of audio output devices, Switching of audio input
devices, Volume adjustment, and Playback functions.
Remote Connections: The NAD T 757 is fitted with the
following custom remote inputs/outputs.
- DC Trigger: The 3.5mm +12 volt output trigger is programmable
and can engage when the receiver is turned on, when Zone 2 is turned on, or when a
specific source is used. The output can also be delayed up to 15 seconds.
- IR In/Out: These 3.5mm connectors (one input and two
outputs) allow you to connect the T 757 to an infrared repeater and other
components with IR inputs.
- RS-232C: The RS-232C port is to be used in conjunction with
an external controller; AMX, Crestron or a compatible PC using NAD's proprietary
Switched AC: The maximum output on the 3-prong switched AC
outlet on the rear panel is 120 watts/1 amp.
