THANK YOU FOR CHOOSING NAD.
The T 755 A/V Receiver is a technologically advanced and highly capable
product — yet we have invested great eort in making it simple and easy
to use. The T 755 delivers a range of genuinely useful options for surround
sound and stereo listening, using powerful digital signal processing and
superbly accurate digital-audio circuitry. However, we have also been
careful to ensure that the T 755 is as musically transparent and spatially
accurate as possible, incorporating much of what we’ve learned from
a quarter century’s experience designing audio and home-theater
components. As with all our products, NAD’s “Music First” design philosophy
guided the T 755’s design, such that it can condently promise you both
state-of-the-art surround home-theater and audiophile-quality music
listening for years to come.
We encourage you to take a few minutes now to read right through this
manual. Investing a little time here at the outset might save you a good
deal of time later, and is by far the best way to ensure that you make the
most of your investment in the NAD T 755, and get the most from this
powerful and exible home-theater component.
One more thing: We urge you to register your T 755 ownership on the NAD
Worldwide Web site:
<http://NADelectronics.com/warranty>
For warranty information contact your local distributor.
INTRODUCTION
ABOUT THE T 755
Though the T 755 is among the most technically sophisticated A/V receiver,
we worked hard to make it one of the most musically transparent hometheater components available as well; this is what we mean by NAD’s “Music
First” design philosophy. Here are just few examples:
• The T 755 uses NAD’s proprietary Power Drive™ amplier technology
for all channels to preserve accurate, linear reproduction regardless
of the loudspeaker. This uniquely ecient power-supply topology
provides the real-world benets of high dynamic power that remains
uncompromised by low-impedance speakers. The result is dynamic,
detailed,”un-receiver-like” sound in stereo and multi-channel modes
alike. NAD’s exclusive Soft Clipping™ circuitry further enhances sound
quality and dynamic potential.
• High-performance components used throughout the receiver’s analog
audio circuits to maximize quality from all sources, including multichannel analog sources such as DVD-Audio and SACD.
• Preamp output (all channels) and main-amp input jacks make potential
expansion as exible as possible.
• Zone pre-amp and video feed with assignable 12 V DC trigger control.
• A Second set of Speaker terminals (Speakers B) for remote listening.
• An RS-232 port for advanced zone control and software update through
a Windows® compatible PC.
• Gold-surfaced connectors are employed throughout to ensure
maximum signal integrity.
E.A.R.S. AND DIGITAL SURROUND
A key element of the T 755’s unique musical aptitude is NAD’s proprietary
Enhanced Ambience Recovery System (EARS). In sharp contrast to many
“ambience-synthesis” music-surround modes, EARS exploits the T 755’s
substantial DSP power to route the ambient content that is “encrypted” in
virtually all natural-acoustic recordings to the appropriate main, center and
surround speakers, without resorting to articially generated reections
or regeneration. EARS’ natural ambience yields a subtle but exceptionally
eective surround mode that naturally enhances the spatial presentation in
a fashion suitable for serious music listening.
Dolby Pro Logic IIx Music and DTS Neo:6 Music modes can also create
enjoyable experience from 2-channel sources.
On the digital side, the T 755 combines extraordinarily high-speed DSP
processing employing one of the most advanced high-speed DSP “engines”
available, with fully 24-bit, 192 kHz-sampling-capable D/A converters for
all channels. A single, high-precision master clock synchronizes all digital
circuits to eliminate the timing errors (jitter) that otherwise compromise
sonics. The result is legitimately state-of-the-art surround decoding from
Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with
genuinely superior sound quality in all modes.
INTEGRATION
The T 755 A/V Receiver oers extensive, exible system-integration options
through its congurable DC trigger outputs and input, and its standardprotocol IR communications links. The DC trigger outputs can be assigned

the user by interface software. See your NAD audio specialist for further
information.
UPGRADABILITY
The T 755 A/V Receiver permits exible system growth via individually
accessible pre-out and main-in jacks for all channels. We have made the
more likely scenario of software upgrades easy to accomplish via the high
speed RS-232 port on the rear panel of the T 755. Owners who register
their T 755 on our international web site www.NADelectronics.com will be
advised of updates. Some of these may be free of charge, and some may
require royalty payments depending on the type of upgrade. The advanced
user will be able to perform these upgrades by downloading les from our
web site, via e-mail and installing them by connecting the T 755 to a PC.
Alternatively the dealer from whom you purchased your T 755 should be
able to assist in performing these upgrades.
ABOUT THE HTR 3 SYSTEM REMOTE CONTROL
Packed with your T 755 is the NAD HTR 3 remote control, a full-system
remote especially designed for easy use and understanding. Be sure to read
the section “Using the HTR 3 Remote Control”, to familiarize yourself with
the remote’s layout and operations before proceeding to setup your T 755.
You may opt to use your HTR 3 as your primary way to command your
entire AV system. The HTR 3 can be employed to operate additional NAD or
other-brand components such as a DVD/CD player, television, satellite/
HDTV tuner, VCR, or virtually anything else that operates via standard
infrared remote.

EASE OF USE
Despite the eort NAD has invested in the T 755 A/V Receiver’s sonic
performance, we expended no less in making it powerfully easy to use.
Its design is uniquely simple for so sophisticated a component, and the
HTR 3 universal remote control is equally understandable, as are the T 755’s
own front-panel and on-screen displays. Its simple yet powerful system
of “presets” permits you to ne-tune your listening setup for dierent
conditions, sources, or listeners, and to recall these multiple parameters
with a single key press.

GETTING STARTED
WHAT’S IN THE BOX
Packed with your T 755 A/V Receiver you will nd
• An AM loop antenna.
• A FM ribbon-wire antenna with balun.
• A removable AC cable (if you wish, any IEC-standard AC cable of suitable
wattage may be substituted).
• The HTR 3 remote control with 4 (four) AAA batteries.
• The ZR 4 zone remote control with 3V CR2025 battery.
• This owner’s manual.
SAVE THE PACKAGING
Please save the box and all of the packaging in which your T 755 arrived.
Should you move or otherwise need to transport your T 755, this is by far
the safest container in which to do so. We’ve seen too many otherwise
perfect components damaged in transit for lack of a proper shipping
carton, so please: Save that box!
CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to both
sides and behind), and that will provide a clear line of sight, within 23 feet/7
meters, between the T 755’s front panel and your primary listening/viewing
position—this will ensure reliable infrared remote control communications.
The T 755 generates a modest amount of heat, but nothing that should
trouble adjacent components.
It is especially important that sucient ventilation be provided. If you are
contemplating on locating the T 755 within a cabinet or other furniture,
consult your NAD audio/video specialist for advice on providing adequate
airow.
QUICK START
Packed with your T 755 is a Quick Start Guide that will guide you through
typical setup congurations in combination with your ancillary devices. The
Quick Start Guide also features the contents of your T 755 package as well
as start up procedures.
The T 755 is defaulted to the following settings:

DEALING WITH HUM AND NOISE
Hum and noise may sometimes prove a challenge in complex, multichannel audio systems. Note these considerations to help prevent hum and
noise problems:
• Power all your system’s audio component from AC outlets originating
from the same circuit of your house wiring. As far as possible, power
all audio components from the same outlet, or adjacent outlets on the
same circuit. It may be useful to power video displays (and computers!)
from outlets on another circuit, especially if that circuit is supplied from
the other “leg” of the house wiring.
• Do not bundle analog audio cables with AC power cables, or with
coaxial digital-audio cables. It is best if they cross at right angles if they
must be in close proximity.
• Employ high-quality, well-shielded audio cable throughout, and ensure
that all connections are secure.
• A pencil-eraser can be used to burnish copper- and gold-plated
contacts to ensure good, low-resistance contact; specialized contactcleaners can also be useful. Avoid unnecessary unplugging and
re-plugging since the gold (or copper) contact plating of typical cable
connectors, even very high-quality ones, is very thin and easily worn.
Track down hum/noise problems one component at a time, working
backwards from the A/V Receiver. That is
1 Connect the speakers to the A/V Receiver only, and check for hum.
2 Then connect one component only (a CD player, for example) alone,
with no other components connected and check for hum.
3 Connect additional components, one at a time, to the A/V Receiver and
check for hum.
At each stage, if hum/noise appears, examine the audio cabling and ACpower routing of the new component. In some cases, moving the new
component’s AC cord to a dierent outlet, or installing a ground-lift (3-to-2prong adapter) on its power cord, will eliminate the hum.
To modify the above default settings and for a better understanding of
source setting and combinations, please refer to the section on ‘Source
Setup’ of the Setup Menu discussion.
NOTES
• Digital input will always take precedence over analog audio input even
if both are present.
• The T 755 is optimized for Component Video Output. Composite
video and S-video sources may be viewed in their native format or via
Component Video OUT.

such as a cassette deck, DVD recorder or to an outboard audio/video
processor. Connect the T 755’s AUDIO 3 IN/VIDEO 3 IN or AUDIO 4
IN/VIDEO 4 IN jacks to the component’s corresponding output.
The signal present at these T 755 AUDIO/VIDEO OUT jacks is determined
by the source last selected via the front panel Source keys or the HTR 3’s
input select keys with the exception of Source 3 or Source 4. There will
be no output when Source 3 (Audio 3 IN/Video 3 IN) or Source 4 (Audio
4 IN/Video 4 in) is the selected source input. This prevents feedback
through the recording component thereby preventing possible
damage to your speakers.
11 MONITOR (S-VIDEO, VIDEO): Connect to video input of the monitor/
television using quality dual-RCA and/or S-Video cables designed for
video signals. In general, the S-Video connection is superior and should
be used if your TV/monitor provides the corresponding input.
12 ZONE 2: Sends zone selected audio and video output sources to the
corresponding audio and video input of another separate zone. Use
high quality patch cables to reduce noise pickup over long distance
runs. For a better understanding of zone settings, study below the
section on “ZONE CONTROLS” of the “MAIN MENU” discussion as well as
the item on “ZONE SETUP” under the “SETUP MENU” literatures.
13 7.1 CH INPUT: Connect to the corresponding analog audio outputs of a
multichannel source component such as a DVD-Audio or multichannelSACD player or external multichannel decoder (disc copy protected
formats only allow analog signal transfer). Typically, these sources will
produce 5.1-channel output, in which case the Surround Back jacks are left
unconnected. The signals present at these jacks may be heard by selecting
Source 7 (7.1 Channel Input is defaulted to this Source).
There is no bass-management or other processing (other than master-
volume control) available to this 7.1 Channel Input. While the multichannel audio outputs of a DVD-Video player can be connected to
these jacks, using the T 755’s own Dolby Digital and DTS decoding and
digital-analog converters via a digital connection will usually produce
superior results.

the HDMI OUT connectors of source components such as DVD player or
HDTV satellite/cable box. Connect the HDMI Monitor OUT to a HDTV or
projector with HDMI input.
17 SPEAKERS A, SPEAKERS B : Connect the respective SPEAKER A’s
FRONT L, FRONT R, SURR R, SURR L and CENTER channels to their
corresponding loudspeakers. Make sure the “+” (red) terminal and
“-“(black) terminal are connected to the corresponding “+” and
“-“terminals of the loudspeaker. Use extra care to ensure that no stray
wires or strands cross between posts or terminals at either end.
Connect left and right channels of Speakers B to the corresponding
remote loudspeakers. When Speakers B is activated, the output is
converted to “Stereo” as indicated in the VFD. Combining Speaker A
and Speaker B (SPEAKERS A + B) will also result to the source being
downmixed to stereo.
The T 755 is designed to produce optimum sound quality when
connected to speakers with impedances within its operating range.
Please make sure that all the speakers are rated 4 ohms minimum per
speaker.
NOTE

NOTE
The individual congurations set forth at “Listening Mode”, “DSP Options” and “Tone Controls”
are carried over whenever they are enabled during A/V Preset setting. Please see the section “A/V
PRESETS” for reference.
LISTENING MODE
The T 755 oers distinct listening modes, tailored for dierent types of recording or program material.
With a two-channel (Stereo) source, the following listening modes can be selected:
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 only as Lt/Rt (left/right-total) signals.
PRO LOGIC
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro
Logic surround processing, yielding output to front left/right, center and discrete left/right surround
channels (assuming these are present in the current “Speaker Conguration”). The surround channel is
monophonic, but it is reproduced in both surround speakers.
PRO LOGIC PLII
Dolby Pro Logic II is a more recent evolution of the original Dolby Pro Logic surround processing that
yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, oering
sound that is more similar to Dolby Digital decoding.
PRO LOGIC IIx
Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby
Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience
to the source material. Dolby Pro Logic IIx surround processing yields more stable imaging and
full bandwidth sound to the rear channels in Movie mode oering sound that is more similar to
Dolby Digital decoding. For two channel signals, Dolby Pro Logic IIx Music mode also features three
additional user controls - Dimension, Center Width, and Panorama. See also section about “ADJUSTING
LISTENING MODES” below.
The following chart shows the channels available assuming they are enabled in the “Speaker
Conguration” menu;

NOTE
The mention of “Back Surround (left, right)” refers to your external amplier’s corresponding “Back
Right” and “Back Left” speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it
possible to use the T 755 as a pre-amplier to external power ampliers for some or all channels.
NEO:6
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround
with output to front left/right, center and discrete left/right surround channels plus subwoofer
(assuming these are present in the current “Speaker Conguration”). The T 755 provides two DTS Neo:6
variations - CINEMA and MUSIC. See also section about “ADJUSTING LISTENING MODES” below.
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 (assuming these are present in the current “Speaker Conguration”). 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 reproduced in stereo via the maximum speaker complement congured in the current
“Speaker Conguration”. 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 Setup” settingare also not in eect as these are DSP functions.
