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 home-
theater 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™ amplier technology
for all channels to preserve accurate, linear reproduction regardless
of the loudspeaker. This uniquely ecient power-supply topology
provides the real-world benets 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 multi-
channel 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 articially generated reections
or regeneration. EARS’natural ambience yields a subtle but exceptionally
eective 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.
EASE OF USE
Despite the eort 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 dierent
conditions, sources, or listeners, and to recall these multiple parameters
with a single key press.
INTEGRATION
The T 755 A/V Receiver oers extensive, exible system-integration options
through its congurable DC trigger outputs and input, and its standard-
protocol IR communications links. The DC trigger outputs can be assigned
to Main, Zone and Source Setup locations.
ZONE
The T 755 A/V Receiver is equipped with a congurable Zone 2 that makes
full use of video and pre-amp level audio outputs. The ZR 4 remote control
will allow you complete access to Zone 2 applications including access to
volume On/O and all sources inputs.
RS 232
Flexible system conguration is possible with the RS-232 interface and
NAD’s proprietary Windows® compatible software. We are also certied
partners with AMX and Crestron and fully support these external devices.
This interface allows complete remote control of the T 755 from any remote
location via the PC. Complete remote control functionality is available to
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.

INTRODUCTION
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 sucient 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
airow.
QUICK START
Packed with your T 755 is a Quick Start Guide that will guide you through
typical setup congurations 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:

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.
DEALING WITH HUM AND NOISE
Hum and noise may sometimes prove a challenge in complex, multi-
channel 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 contact-
cleaners 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 AC-
power routing of the new component. In some cases, moving the new
component’s AC cord to a dierent outlet, or installing a ground-lift (3-to-2-
prong adapter) on its power cord, will eliminate the hum.

1 IR IN/OUT: These mini-jacks accept and output remote-controlled
codes in electrical format, using industry-standard protocols, for use
with “IR-repeater” and multi-room systems and related technologies.
IR IN : This input is connected to the output of an IR (infrared) repeater
(Xantech or similar) or the IR output of another component to allow
control of the T 755 from a remote location.
IR OUT 2 : When connected to the IR IN of ancillary equipment, direct
the ancillary equipment’s own remote control to the T 755’s infrared
receiver to command or control the linked unit.
IR IN and IR OUT 3 : Connect the T 755’s IR IN to the IR OUT of ancillary
equipment. Connect also the T 755’s IR OUT 3 to another equipment
with IR IN feature. With this setup, the T 755 acts as an “IR-repeater”
allowing the equipment connected to the T 755’s IR IN control or
command of the other equipment linked to the T 755’s IR OUT 3.
IR OUT 1 : In conjunction with IR IN, IR OUT 1 can be used as an “IR-
repeater” just like the IR OUT 3 as described above. It can also stand
alone as an IR OUT similar to that of IR OUT 2 function.
All NAD products with IR IN/IR OUT features are fully compatible with
the T 755. For non-NAD models, please check with your other product’s
service specialists as to their compatibility to the T 755’s IR features.
2 +12 V TRIGGER OUT: There are three congurable +12V TRIGGER
OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a
maximum current of 200 milliamps to auxiliary equipment such as a
multichannel amplier or subwoofer. The centre conductor (hot) of the
3.5mm jack is the control signal. The outside conductor (shield) is the
ground return-path.
TRIGGER IN accepts 12V Trigger output of compatible components such
as power controllers and home automation devices.
TRIGGER OFF/AUTO. When at AUTO position, the T 755 selects the 12V
Trigger Input to turn ON (if so assigned at the“Trigger Setup”menu) and
at the same time disables the HTR 3 and ON/OFF function of the front
panel. When set to [OFF] position, the trigger input is disabled.
See discussion on “TRIGGER SETUP” at the “SETUP MENU”literature for
guidelines on how to congure TRIGGER IN/OUT.
WARNING

the TRIGGER switch is set to “AUTO” mode, the Power button in the front
panel as well as the corresponding ON/OFF function keys in the HTR 3
remote control will be disabled eectively handing this function to an
external controller. Switch TRIGGER to”OFF” to maintain normal power
ON/OFF function procedures.
3 SOFT CLIPPING: Enables NAD’s proprietary Soft Clipping circuitry on
all channels. At [ON] position, Soft Clipping gently limits the output of
the T 755 to minimize audible distortion should the A/V Receiver be
over-driven. Soft Clipping may simply be left ON at all times to reduce
the likelihood of audible distortion from excessive volume settings.
However, for critical listening and to preserve optimum dynamics, you
may wish to defeat it by setting this switch OFF.
4 FM, AM ANTENNA INPUT: The supplied wire“dipole”FM antenna will
connect to the FM connector using the supplied “balun” adapter. It will
usually work best when mounted on a vertical surface such as a wall,
with arms fully outstretched forming a horizontal“T” perpendicular to
the origin point of the signal.
Connect the supplied AM loop antenna to these terminals. If an external
AM antenna is used, make connections to the AM and GND terminals
in accordance with the instructions supplied with the antenna. See also
section about “LISTENING TO RADIO”.

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 multichannel-
SACD 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 multi-
channel 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.

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, oering
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 oering sound that is more similar to

possible to use the T 755 as a pre-amplier to external power ampliers 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 Conguration”). 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 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 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

ANALOG AUDIO
The T 755 has nine analog audio inputs including 7.1 input. These analog inputs - Audio 1, Audio 2,
Audio 3, Audio 4, Audio 5, Audio 6, Audio Front, Audio MP and 7.1 Input can be variably assigned to
each Source.
Scroll to“Analog Audio”and then press [ ] to select and assign an analog audio input to the particular
Source. There are three choices – Audio, 7.1 Input or O.
When “Audio” is chosen, press [ ] and then [ ] keys to select and assign the desired audio input
– 1 to 6, Front and MP.
Select “7.1 Input” to choose the audio signal fed to“7.1 Channel Input”. If “O” is selected, no incoming
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.
GAIN
Gain adjustment allows all sources to play back at the same volume 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“Gain”, press [ ] and then [ ] to step through the desired level from -12dB to 12dB.
DIGITAL AUDIO
To take advantage of the T 755’s high performance surround and digital audio circuitry, it is advisable
that its Digital Audio inputs are selected.
There are two types of Digital Audio input for the T 755: Optical and Coaxial. A third option is“O”whereby
no incoming digital audio signal is selected by the particular Source.
The desired digital audio input for a particular Source can be selected by scrolling to“Digital Audio”, press
[ ] and then [ ] to step through the desired digital input source. After nalizing which type of Digital
Audio input is desired, press [ ] and then [ ] again to select the specic Digital Audio input.
There are seven Digital Audio inputs selectable for the T 755. They are the following
Optical Optical 1, Optical 2, Optical 3, Optical Front
Coaxial Coaxial 1, Coaxial 2, Coaxial 3
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
There are four types of video input a particular Source could be assigned. These are HDMI, Component,
S-Video and Video inputs. A fth option is“O” wherein the particular Source is prompted not to select
any Video input.
Navigating through the Video input selections involve a combination of pressing [ ] and then [ ]
to step through the selections. The following are the assignable Video inputs
HDMI HDMI 1, HDMI 2, HDMI 3
Component Video Component 1, Component 2, Component 3
S-Video S-Video 1, S-Video 2, S-Video 3, S-Video 4, S-Video 5, S-Video Front
Video Video 1, Video 2, Video 3, Video 4, Video 5, Video Front
NOTE
An audio input and video input should always be associated to a selected Source setting to ensure audio and video
output. If “O” is selected for any of the Analog Audio, Video or Digital Audio settings, there will be no corresponding
audio or video for the associated Source. For example, if the selected Video setting for a particular Source is
Component 1 and both Digital and Analog Audio are set to “O”, only video output will be available but no audio.
Ideally, when the selected Video input is Component 1, it follows that the Digital Audio input is set to Optical 1 or any
of the digital inputs. Refer also to the QUICK START section under the INTRODUCTION – GETTING STARTED page.

ABOUT VIDEO FORMATS
For many years, there was only one type of video format used. Composite video signals include the
Luminance (black & White) and Chroma (color) signals combined on one wire. S-Video uses separate
wires in a single cable for Luminance and Chroma signals. Component Video goes a step further
with separate cables for Luminance and the two elements of Chroma. For NTSC (America, Japan)
as well as PAL signals(Europe, Asia) these are labeled Y, Cr, Cb. Television studios use the Component
Video format to keep these signals separate in order to maintain the best quality. As consumer video
equipment has improved this higher quality format has been included.
VIDEO FORMAT CONVERSION
The T 755 is equipped with a Video Format Converter. This allows for a simplied video connectionbetween
the T 755 and your TV Monitor when using multiple video formats such as Composite (CVBS), S-Video, and
Component (YUV). This format change is accomplished by encoding the analog video signal intoa digital
signal using a very high quality digital encoder to maintain the best possible picture quality. Once in a
digital format, it can be decoded into any of the three standard analog video formats.
It is suggested that you select the highest quality video format available on your TV Monitor and utilize this
for your Monitor OUT connection from theT 755 to the TV Monitor. In most cases this will be Component
Video, but on some olderTV’s S-Video may be the best quality connection. See also the item“3 COMPONENT
VIDEO 1-3, COMPONENT VIDEO OUT”under“Identication of Controls – Rear Panel”discussions.
NOTES
Video signals are converted between all three formats:
• Composite, S-video and Component Video.
• All three monitor outputs will always be active no mater what the source format is.
• OSD menu is always available on all three output formats.
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 (Please refer to the separate section on
“A/V PRESETS” for further understanding of Preset settings).
Scrolling to“A/V Preset” and by pressing [ ] and then [ ] keys, a Source could be assigned a
Preset number ranging from Preset 1 to 5.
If it is desired not to assign the particular Source a Preset setting, select“None”.
TRIGGER OUT
The Trigger Out for a particular Source is dependent on the congurations done in a separate menu on Trigger
Setup (See“TRIGGER SETUP”below). If all three available Trigger outputs are assigned to“Source Setup”in the
separate“Trigger Setup”window, a particular Source can have the followingTrigger Out combinations
Trigger Out 1 2 1 + 2 3 1 + 3 2 + 3 1+2+ 3
These combinations are dependent on the assignment of“Source Setup”for “Trigger 1 Out, Trigger 2
Out or Trigger 3 Out” at the Trigger Setup menu.
Another option is “O” whereby the particular Source is not assigned any Trigger Out.
For “Trigger Out”to become enabled and assignable at “Source Setup (Normal View)”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 (Normal View) menu if at the
separate “Trigger Setup” menu, “Trigger 1 Out, Trigger 2 Out or Trigger 3 Out” are all assigned to
“Main”or “Zone 2”without a single “Trigger Out”port allocated to “Source Setup”.
SOURCE SETUP (TABLE VIEW)
The Source Setup (Table View) reects the settings made in the Source Setup (Normal View) menu. All
the Source settings are summarized and displayed in tabulated form in the Source Setup (Table View).
Navigating through the Source Setup (Table View) via a combination of [ ] and then [ ] keys,
one will have the benet of directly changing the settings for “Audio, Video, Preset, Trigger and Source
Name”without going back to the Source Setup (Normal View) menu.

the “Now Playing”OSD to be shown, there should be a song paused or being played before going
to the iPod menu. You can set the “Menu Timeout” between the range 5s to 60s at 5s increments. If
you do not want for the menu to timeout, select“O”.
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.
AUDYSSEY SETUP
It has been shown that many, if not most, surround sound systems are not accurately congured and setup.
This requires special knowledge and instrumentation that the average person probably doesn’t possess.
The T 755 has the capability to automatically setup your own unique Home Theatre’s speaker system.
This is achievable through the T 755’s Audyssey Setup feature along with the sophisticated digital
electronics built into your unit.
The installation of your new T 755 is greatly simplied by Audyssey Setup with the end result of
delivering the best quality sound possible given the type of speakers you have as well as your listening
room’s dimensions.
Audyssey Setup takes up only a fraction of time to run compared with setting up your speakers
manually and then achieve results that rival other expensive test and setup measuring devices.
The following measurements are performed:
• Detection : Speaker conguration is detected including the number of surround speakers and
whether a subwoofer and center channel is connected.
• Size : T 755 crossover is set based on each channel’s signal handling capability and the subwoofer
crossover is automatically set.
• Level : SPL of each speaker is matched within 1dB at the microphone position.
• Distance : is accurately set to within 1 foot (30 centimeters) of the microphone for each speaker
position.
• Polarity : the setup program will detect and notify the user if any speakers are connected
improperly. Incorrect polarity can ruin the illusion of realism oered by surround sound.
This is a one-time setup, unless speakers are moved or changed, in which case Audyssey Setup should
be performed again.

ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ

MEASUREMENT IS THE FIRST STEP
Connect the Audyssey microphone jack into the front panel’s MP/MIC input and the Audyssey Setup
wizard will guide you through a simple step-by-step conguration.
The sound at your main listening position is setup using the supplied Audyssey microphone. A special
test tone is sent to each speaker and the data is memorized by the T 755. The duration of setup may
take some time depending on the number of speakers. After the measurements, Audyssey calculates
the ideal system response for your particular room and speaker setup.
If some inconsistencies or discrepancies are detected during the Audyssey setup, the process
maybe interrupted or the problem is shown in the particular setup window. A notice screen is
correspondingly displayed. After following and undertaking the displayed instructions, re-start the
Audyssey setup again. When the measurements are nalized, Audyssey calculates the ideal system
response for your particular room and speaker setup.
NOTES
• The test tone emitted during measurement is loud. This maybe bothersome for you and may aect
as well your other household members and even your neighbor.
• The mention of “Back Right” and “Back Left” refer to your external amplier’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-amplier to external power ampliers for some or all channels.
It is recommended that you take full advantage of the T 755’s Audyssey Setup feature for your speaker
setup. However, if you desire to setup your speakers manually or if you already had run Audyssey Setup
but would like to make adjustments, the following sections on Speaker Conguration, Speaker Levels
and Speaker Distance can also be followed and implemented.
NOTE
During manual setting of your speakers, previously calibrated Audyssey settings could be retrieved
by re-adjusting back the altered congurations as highlighted by an asterisk.
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 80 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”.
