THANK YOU FOR CHOOSING NAD.
The T 175 A/V Tuner Preamplier is a technologically advanced and highly
capable product — yet we have invested great eort in making it simple
and easy to use. The T 175 delivers a range of genuinely useful options for
surround sound and stereo listening alike, using powerful digital signal
processing and superbly accurate digital-audio circuitry. However, we have
also been careful to ensure that the T 175 is as musically transparent, faithful
to every video detail and spatially accurate as possible, incorporating much
of what we’ve learned from a quarter-century’s experience designing audio,
video and home-theater components. As with all our products, NAD’s
“Music First” design philosophy guided the T 175’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 T 175, and get the most from this powerful
and exible home-theater component.
One more thing: We urge you to register your T 175 ownership on the NAD
Worldwide Web site:

For warranty information contact your local distributor.
INTRODUCTION
ABOUT THE T 175
Though the T 175 is among the most technically sophisticated A/V
Tuner Preamplier, 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:
• High-performance components used throughout the A/V Tuner
Preamplier’s analog audio circuits maximize quality from all sources,
including multi-channel analog sources such as DVD-Audio and SACD.
• Audio pre-out jacks make potential expansion as exible as possible..
• Zone pre-amp and video feed with assignable 12 V DC trigger control.
• An RS-232 port for advanced zone control using 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 175’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 175’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.
ZONE
The T 175 is equipped with three congurable Zones that make 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. Zone 3 and Zone 4 could be congured
and managed at the appropriate Zone OSD menu using the front panel
navigations keys as well as the corresponding keys on the HTRC 1 remote
control.
RS 232
Flexible system conguration is possible with the RS-232 interface. This
interface allows complete remote control of the T 175 from any remote
location via the PC. NAD is a certied partner of AMX and Crestron and
fully supports these external devices. Check out the NAD website for
information about AMX and Crestron compatibility with NAD. See your
NAD audio specialist for more information.
ABOUT THE HTRC 1 SYSTEM REMOTE CONTROL
Packed with your T 175 is the NAD HTRC 1 remote control, a full-system
remote especially designed for easy use and understanding. Be sure to read
the section “Using the HTRC 1 Remote Control”, to familiarize yourself with
the remote’s layout and operations before proceeding to setup your T 175.
You may opt to use your HTRC 1 as your primary way to command your
entire A-V system. The HTRC 1 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.
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
On the digital side, the T 175 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 eort NAD has invested in the T 175 A/V Tuner Preamplier’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 HTRC 1 universal remote control is equally understandable, as are the
T 175’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.
INTEGRATION
The T 175 oers extensive, exible system-integration options through its
congurable DC trigger outputs and input, and its standard-protocol IR
communications links. The DC trigger outputs can be assigned to either
Local and/or Zone locations.

WHAT’S IN THE BOX
Packed with your T 175 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 HTRC 1 remote control with 4 (four) AA 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 175 arrived. Should you move or
otherwise need to transport your T 175, 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 25 feet/8 meters, between the T 175’s front panel and your
primary listening/viewing position—this will ensure reliable infrared remote control communications.
The T 175 generates a modest amount of heat, but nothing that should trouble adjacent components.
It is perfectly possible to stack the T 175 on top of other components, but the reverse usually should
be avoided.

QUICK START
Packed with your T 175 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 175 package as well as start up procedures.
The T 175 is defaulted to the following settings:
Source Audio Input Video Input
Source 1 HDMI 1 IN/ Audio 1 IN HDMI 1 IN
Source 2 Optical 2 IN/ Audio 2 IN Component Video 2 IN
Source 3 Coaxial 3 IN/ Audio 3 IN S Video 3 IN

iPod Audio 5 IN S-Video 5 IN
Source 7 7.1 Input Component Video 3 IN
Front Input Optical Front Input/ Audio Front Input S-Video Front IN
Media Player Audio MP input
Tuner
For Video output, select the highest video quality format available on your TV/Monitor and utilize this
for your Monitor OUT connection from the T 175 to the TV/Monitor. In most cases, this would be HDMI
but for other TV/Monitor without HDMI input, the best connection in order of best video quality would
be Component Video, S-Video and Composite video input.

Listening Mode
Two-Channel Sources
Dolby Pro Logic IIx Music
Dolby Pro Logic IIx Movie
DTS 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 175 provides two DTS
Neo: 6 variations - NEO:6 Cinema and NEO:6 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.

ADJUSTING LISTENING MODES
Several of the T 175’s listening modes have one or more selectable
variations and adjustable parameters that you can modify to suit
you system or personal preferences. At Listening Mode menu, use a
combination of ENTER and keys to navigate and eect desired
settings.
NOTE
Listening Mode parameter changes are maintained when you change
listening modes. You may also save a modied Listening Mode for easy
recall by saving it to a Preset (See ‘A/V Presets’ below under Setup Menu
discussions).
PRO LOGIC IIx
PLIIx MOVIE is optimized for lm soundtracks.
PLIIx MUSIC for music recordings
Center Width (0 to 7): Modies 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 (-7 to +7): Adjusts front-rear emphasis of the surround eect
independently from the relative channel levels.
Panorama (On/O): Adds a “wraparound” eect by extending some
stereo content into the surround channels.
NOTE
Pro Logic IIx mode will decode as Pro Logic II mode when the BACK
surround speakers are set to “OFF” from “Speaker Congurations” menu.
See also section about “Speaker Congurations” under “Speaker Setup”
of the Setup Menu.
DTS NEO: 6
NEO: 6 Cinema is optimized for lm soundtracks.
NEO: 6 Music for music recordings
Center Gain (0 to 0.5): Adjust for better center image in relation to the
surround sound channels.
ENHANCED STEREO
All recordings are 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 multispeaker 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 eect as these are DSP functions.

OPERATION
USING THE T 175 MAIN MENU
DSP OPTIONS
The following signal processing parameters can be setup under the DSP
(Digital Signal Processing) Options menu.
IMPORTANT NOTICE
The T 175 is an AV Surround Sound Preamplier and therefore has
no speakers. The mention of “Speaker(s)” in this manual refers to the
speakers of your external amplier as interfaced with the T 175.
LIP SYNC DELAY
DSP Options has the feature ‘Lip Sync Delay’ whose function is to match any
delay that may occur in the picture relative to the audio.
By varying ‘Lip Sync Delay’ from 0ms to 120ms, one can delay the audio
output in order to synchronize it with the video image.
AUDYSSEY MultEQ
Audyssey MultEQ becomes available among the DSP options only after
successfully completing Audyssey Auto Calibration (accessible through
the Setup Menu). Refer also to Audyssey Auto Calibration segment of the
Speaker Setup under Operation – Using the T 175 – Setup Menu.
Audyssey MultEQ can be set to the following levels
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
lters are used in the same way as the Audyssey curve, but it does not
apply a high frequency roll-o.
NAD: Ideal “in room” response developed by NAD engineers along with
Audyssey Engineers.
O: MultEQ lters are not used or no measurement process at all.
NOTES
• “AUDYSSEY” and a lit green box icon are illuminated at the VFD if NAD,
Audyssey or Flat is selected. If “O” is selected, “AUDYSSEY” and the
green box icon will not be illuminated.
• If NAD, Audyssey or Flat is selected and changes are done at the “Tone
Controls”, “Speaker Conguration”, “Speaker Levels” and “Speaker
Distance” settings, “AUDYSSEY” and a lit red box icon are illuminated
at the VFD. Restore the parameter to its previously calibrated Audyssey
setting by adjusting back the altered conguration.
• Audyssey MultEQ options can also be directly selected or changed using
HTRC 1’s AUDYSSEY button with DEVICE SELECTOR set to AMP mode.
Toggle AUDYSSEY button to select “Audyssey MultEQ” and then use the
[ ] to select through the Audyssey MultEQ options. Press AUDYSSEY
again to save the selected option and at the same time move on to the
next menu setting or exit the menu setting altogether.
AUDYSSEY DYN EQ 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.
Audyssey Dynamic EQ selects the correct frequency response and surround
volume levels moment-by-moment. The resulting bass response, octaveto-octave balance and surround impression remained the same despite
changes in volume.
Audyssey Dynamic EQ is designed to work in conjunction with Audyssey
MultEQ. Dynamic EQ determines the proper loudness compensation based
on the sound pressure level measurements MultEQ provides. Audyssey
Dynamic EQ working in tandem with Audyssey MultEQ provides the right
listening conditions for every listener at any volume level.
On: Activate Audyssey Dynamic EQ function.
O: Defeat Audyssey Dynamic EQ function.
NOTE
Audyssey Dynamic EQ and Audyssey Dynamic Volume (see below)
can be directly selected or changed using HTRC 1’s AUDYSSEY button
with DEVICE SELECTOR set to AMP mode. Toggle AUDYSSEY button to
select “Dyn EQ” or “Dyn Vol” and then use the [ ] to select through
their respective options. Press AUDYSSEY again to save the setting and
at the same time move on to the next option or exit the menu setting
altogether.
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, which
compensates for deteriorating sound quality as volume is decreased
by taking into account human perception and room acoustics. 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.
Audyssey Dynamic Volume can be set to the following levels
Light: Provide the least adjustment to the loudest or softest sound
level.
Medium: Setting that prevents loud and soft sound from being much
louder than their respective average sound levels.
Heavy: Aect volume the most by causing all sound to be of equal
loudness.
NOTE
Audyssey Dynamic EQ must be set to “On” to activate Audyssey Dynamic
Volume. If Audyssey Dynamic EQ is set “O”, Audyssey Dynamic Volume
will also remain “O”.
IMPORTANT NOTICE
If Audyssey Auto Calibration is not set up, the relative balance of your
system’s loudspeakers has to be manually adjusted (with the aid of a SPL
meter) for Audyssey Dynamic Volume and Audyssey Dynamic EQ to be
eective. If the speakers are not properly calibrated, the corresponding
Audyssey Dynamic Volume and Audyssey Dynamic EQ responses could
be distorted. Refer also to the item about “USING SPL METER” in the
SPEAKER LEVELS section below.

TONE CONTROLS
PICTURE CONTROLS
The T 175 has three Tone Control levels – Treble, Bass and Center Dialog.
Bass and Treble controls only aect the low bass and high treble leaving the
critical midrange frequencies free of coloration. The Center Dialog (‘Dialog’
in the VFD) control boosts the ‘presence’ of the midrange region improving
intelligibility of speech.
These controls allow one to tweak on-the-y, the frequency response
of the source during playback. The control setting could be adjusted by
navigating through the Tone Controls’ OSD menu via a combination of
ENTER and keys. The same can be managed directly by pressing the
front panel’s ‘TONE CONTROLS’ button and then rotating the Volume knob
to select desired setting.
Maximum and minimum values for all three Tone Control levels are +/- 10 dB.
‘Tone Defeat’ gives one the choice of varying or completely bypassing the
tone control section of the T 175. If ‘O’ (‘Tone Active’ in the VFD) is selected,
the Tone Control circuits are active.
Select ‘On’ (‘Tone Defeat’ in the VFD) to bypass the Tone Controls eectively
defeating the eect of the tone control circuits.
NOTE
Tone Control options can be directly selected or changed using HTRC 1’s
TONE button with DEVICE SELECTOR set to AMP mode. Toggle TONE
button to select “Treble”, “Bass” or “Dialog” and then use the [ ] to
adjust their respective levels. Press TONE again to save the settings and
at the same time move on to the next parameter or exit the parameter
setting altogether.
Picture Controls allow video adjustments of the source material or source
components to suit one’s preference. Set the following levels or settings
according to desired level of preference.
ASPECT MODE
The Aspect Mode allows one the choice of adjusting the video output
conguration of the T 175.
Letterbox: Original aspect ratio is maintained, preserving the original
image’s proportions. The unused areas of the screen are left blank.
Zoom: Video display zooms in to the image or scene, cutting o
portions that do not t. Any unused areas of the screen are left blank
(i.e., black band).
Stretch: Image or scene is stretched sideways. Any unused areas of the
screen are left blank (i.e., black band).
IMPORTANT NOTICE
There is no visible or discernable change in the video display for any of
the above three aspect modes if the “Aspect Ratio” of both the source
component and the T 175’s Video Setup settings (see discussion about
“Aspect Ratio” under “Video Setup” menu at “Setup Menu”) are exactly
the same.
EDGE ENHANCEMENT
Fine details of an image’s hard edges are enhanced without adding ringing
or halos. Select the level upon which the detected area will be enhanced.
Threshold: Adjusts the sensitivity of the edge detection mechanism.
A lower threshold results in more subtle boundaries of color being
identied as edges. A threshold that is too low may result in some small
parts of surface textures, lm grain or noise being incorrectly identied
as being an edge.
16
NOISE REDUCTION
This setting addresses video distortion like video noise and blocking
artifacts. The noise reduction level setting is dependent upon one’s
preference of video or image quality. It is not advisable to adjust the noise
reduction level if there is no perceived video noise to deal with. Turning up
or down the noise reduction level will make an otherwise perfect video to
be distorted or a “noisy” one.
CONTRAST
Adjust bright areas (white level) of the video display.
BRIGHTNESS
Adjust overall brightness of the video display.
NOTE
Picture controls options can also be directly recalled and adjusted by
pressing the numerical “0” key of the HTRC 1 with DEVICE SELECTOR set
to AMP. Use the [ ] keys to select through the settings of a particular
option or adjust the levels.
