THANK YOU FOR CHOOSING NAD.
The T 175 AV 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, 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 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 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 NAD 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:
<http://NADelectronics.com/warranty>
For warranty information contact your local distributor.
INTRODUCTION
ABOUT THE T 175
Though the T 175 is among the most technically sophisticated 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 Tuner
Preamplier’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.
• 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 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.
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 AV 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

To navigate through these Main Menu options and their sub-menu selections, please refer to and
follow the directions stated in the sections “DISPLAY THE OSD” and “NAVIGATING THE OSD AND
MAKING CHANGES”.
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 175 oers nine 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:
IMPORTANT NOTICE
The T 175 is a Tuner Preamplier only and therefore has no Speakers. The mention of “Speaker(s)” in
this manual refers to your external amplier’s speakers as interfaced with the T 175.
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

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 - 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” are also not in eect as these are DSP functions.

DSP OPTIONS
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.
TONE 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 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

SETUP MENU
The Setup Menu allows one to customize the operation of the T 175 to the ancillary equipment used
in one’s specic AV system. Unless your system exactly matches the factory defaults as shown in the
accompanying Quick Start Guide, you will need to use the setup menu to congure the inputs of the
T 175.
At Setup Menu, the following are congurable – Source Setup, Speaker Setup, Zone Setup, Trigger
Setup, Listening Mode Setup, Display Setup and A/V Presets.
To access and navigate through Setup Menu and its sub-menu selections, please refer to and follow the
directions stated in the sections “DISPLAY THE OSD” and “NAVIGATING THE OSD AND MAKING CHANGES”.
SOURCE SETUP
From Source Setup menu, pressing [ ] will direct you to the Source Setup menu wherein you could
adjust allocate or change the settings of the following – Source Setup (Normal View), Source Setup
(Table View) and iPod Setup.
SOURCE SETUP (NORMAL VIEW)
The Source Setup (Normal View) makes it possible to set, allocate or change the following settings.
SOURCE
The T 175 is equipped with ten congurable Sources. The settings for each Source are dependent on
the congurations set forth in the parameters for that particular Source window.
To change or toggle through the Sources, scroll to “Source”, press the buttons [ ] and then [ENTER] or
[ ] to move up or down the Source selections.
NOTE
Source 5 is defaulted to iPod. For Source 5 to be changed and allocated for other inputs, go to ‘iPod
Setup’ menu under the ‘Source Setup’ menu. At iPod Setup menu, set “Enabled” to “No” – you can
now assign Source 5 to other inputs or settings as desired.
ENABLED
One can enable/disable a Source via this option. This is particularly useful if only few Sources are used
and one directly selects the Source from the front panel, bypassing unused sources.
To enable or disable a particular Source, scroll to “Enabled” and press [ ] keys to select “Yes” or “No”.
NAME
A new Name maybe assigned to a Source label. For example, if your DVD player is attached to
“Source 1”, it is possible to rename “Source 1” to “DVD Player”.
In order to rename the Source label, scroll to “Name” and press [ ] to go the character. Then, press [ ]
to pick through the alphanumeric selections.
Press [ ] to move to the next character and at the same time save the changes done on the
current character. The name can be as long as twelve characters.

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 175 is equipped with a Video Format Converter. This allows for a simplied video connection
between the T 175 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 into a 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. These analog outputs are also up-converted to HDMI output. Video output availability will
depend on the resolution capability of your TV/Monitor.
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 the T 175 to the TV Monitor. In most cases this will be Component
Video or HDMI (where possible), but on some older TV’s S-Video may be the best quality connection.
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 congurations 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 following Trigger 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”, “Zone 2”, “Zone 3”, “Zone 4”, or “Zone 2+3+4” without a single “Trigger Out” port allocated to
“Source Setup”.
SOURCE SETUP (TABLE VIEW)
The Source Setup (Table View) reects 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 benet of directly changing the settings for “Audio”, “Video”, “Preset”, “Trigger” and
“Source Name” without going back to the Source Setup (Normal View) menu.
iPod SETUP
The iPod Setup menu allows you to preset the following associated settings when iPod is the selected
source:
Enabled: Select “Yes” to enable iPod as a Source or “No” to disable it.
Auto: Select “Yes” to automatically enable and connect the iPod player docked in the linked NAD
iPod docking station when Source 5 (the default iPod source allocation in the T 175) is selected.
Select “No” if you do not want for the iPod connection automatically connected.
Menu Timeout: Set the time for the OSD to revert to the “Now Playing” display when the iPod
menu has been left idle (no scrolling or navigation being done) for the specied time out time. For
the “Now Playing” OSD to be shown, there should be a song paused or being played before going

AUDYSSEY AUTO CALIBRATION
It has been shown that many, if not most, surround sound systems are not accurately setup and
calibrated. To be done properly, calibration requires special knowledge and instrumentation that the
average person probably doesn’t possess.
The Audyssey Auto Calibration featured in T 175 uses a microphone, along with sophisticated digital
electronics built into your T 175, to automatically setup and calibrate the T 175 to the exact speakers
and speaker placement of your own unique Home Theatre.
The following measurements are performed:
• Detection: Speaker conguration is detected including number of surround speakers and
whether a subwoofer and center channel is connected.
• Size: T 175 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 oered by surround sound.
This is a one-time set up, unless speakers are moved or changed, in which case the calibration should
be performed again.
AUDYSSEY MultEQ XT ROOM ACOUSTICS CORRECTION
Sound reecting from room boundaries can disturb the spatial illusion of surround sound, and can also
distort the tonal balance of the system. Professional Acoustical Engineers often add wall treatments
and even move walls and relocate speakers to improve system performance, but for the average Home
Theatre, this is either too expensive or just not a practical solution.
Audyssey MultEQ XT, using multiple measurements from the actual listening positions, and processing
this information using very sophisticated digital signal processing, is able to “precondition” the signal to
eectively make the walls disappear. This creates a “family size” sweet spot where the sound and spatial
cues are very accurately reproduced.
MultEQ XT is designed to tame room acoustics without changing the sonic character of your
loudspeakers. While it will make the most of whatever loudspeakers you have, it will not make poor
speakers sound like good ones!
Connect the Audyssey microphone jack into the front panel’s MP/MIC input and the Audyssey Auto
Calibration wizard will guide you through a simple step-by-step conguration. Once setup and
calibrated, the next greatest improvement in performance is obtained by eliminating the acoustic
interference caused by room boundaries interacting with your speakers.

USING THE T 175 SETUP MENU
MEASUREMENT IS THE FIRST STEP.
The sound at each listening position (up to 8 positions) is calibrated using the same microphone used
during the setup phase.
A special test tone is sent to each speaker and the data is memorized by the T 175. The duration of
calibration may take some time depending on the number of speakers as well as the number of
measuring points. After all positions are measured, the DSP calculates the ideal system response for
your particular room and speaker setup.
If some inconsistencies or discrepancies are detected during the Audyssey calibration, 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 calibration again. When the measurements are nalized, Audyssey calculates the ideal
system response for your particular room and speaker setup.
NOTE
The test tone emitted during measurement is loud. This maybe bothersome for you and may aect
as well your other household members and even your neighbor.
NEXT A TARGET CURVE MUST BE CHOSEN.
Because loudspeaker designers assume that their products will be used in typical domestic rooms,
they are “voiced” to work in this environment. It is assumed that the room will add some bass
reinforcement and will absorb some treble energy. Thus if we eectively “remove” the walls with room
correction, and set the speakers for at response, you may nd this sounds too bright in the treble and
too weak in the bass region.
NAD engineers have done extensive research in this area of room acoustics, and along with Audyssey
engineers developed what we believe is the ideal “in room” response curve. We include this NAD EQ,
along with an Audyssey developed EQ as the two best choices. The response curves shown below
typify NAD EQ room correction process.
Room Response measured by Audyssey microphone Inverse Correction Filter calculated by NAD T 175
Corrected Room Response
Flat EQ is a third option, but not one that we recommend for listening (it is useful for verifying system
performance when using external instrumentation).
Select the Target Curve you nd to be most satisfactory by pressing the Audyssey key of the remote.
The MultEQ XT corrected response can also be bypassed if you wish.
It is recommended that you take full advantage of the T 175’s Audyssey Auto Calibration feature for
your speaker setup. However, if you desire to setup your speakers manually or if you already had run
Audyssey Auto Calibration but would like to make adjustments, the following sections on Speaker
Conguration, 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 congurations 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 signicant 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”.
Depending on the relationship between speakers, the possible selections for each speaker are as
follows:

Speaker Conguration can be managed and adjusted by pressing a combination of [ ] and then [ ]
keys. Set “Front”, “Center”, and “Surround” to “Large,” “Small” or “O” as your subsystem’s speakers require.
The “Back” speakers can either be one or two speakers. Set “Back” to either 1 or 2 speakers as per

ENHANCED BASS
When the subwoofer is set to ON and one or more speakers are set to “Large”, Enhanced Bass is also
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. Please note that
due to acoustic cancellation eects, the bass response may be uneven when using this setting.
You can set Subwoofer to “On” even with “Large” front speakers, in which case bass content from any
channels set to “Small” will be routed to both the subwoofer and to the front speakers; LFE-channel
signal will pass only to the sub. In most subwoofer-equipped systems, setting front speakers to “Small”
is usually the better option.
All the speakers’ low frequency content can be directly adjusted within the range 40Hz to 200Hz.
NOTE
The congurations set forth at “Speaker Setup” are carried over whenever it is enabled during A/V
Preset setting. Please see also the section “A/V PRESETS” for reference.
SPEAKER LEVELS
Adjusting the relative balance of your system’s loudspeakers ensures that surround-sound recordings,
whether music or lm, will present the balance of eects, music, and dialog that the artists intended.
Additionally, if your system incorporates a subwoofer it establishes a correct relationship between the
volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic
elements.
USING AN SPL METER
It is quite practical to perform the T 175 level setup routines “by ear,” and careful work will produce
acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter,
such as Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable.
Ownership of such a meter could prove a valuable audio tool. Your NAD audio specialist may be able
to help you with temporary use of a meter.
The SPL meter should be placed at the primary listening position, at approximately the height of
the seated listener’s head. A tripod is helpful but with a little duct tape almost anything — a pole
lamp, music-stand, or ladder-backed chair, for example — can do as well. Just be sure that no large
acoustically reective surfaces obstruct or are near the microphone element.
Orient the meter with its microphone (usually at one end) pointing straight up toward the ceiling (not
toward the speakers) and ensure that “C” weighting scale is selected. Set the meter to display 75 dB
SPL. On Radio Shack meters, this necessitates either setting the meter to its 80 dB range and taking
your readings at the -5 point or selecting the 70 dB range and reading at the +5 point.
SETTING SPEAKER LEVELS AT TEST MODE
While at “Speaker Levels” menu, press the HTRC 1 remote’s “Test” key activating the T 175’s Speaker
Levels balancing test signal . You will hear a “surf ” sound as you step through your speakers (“test”
appears to the right side of the current speaker), beginning with the Front Left. If you do not hear the
test signal, check your speaker connections or your “Speaker Setup” menu settings.
Use the remote’s [ ] keys to adjust the loudness of the noise output from the currently playing
channel to the required level (it’s usually simplest to begin with the Front Left). As you cycle the test
signal around the speakers, the OSD will highlight the currently playing channel. The “level oset”
reading on the right will change by 1 dB increments; ±12 dB adjustment is available. Press ‘ENTER’ to
adjust the next speaker.
NOTE
If you are balancing levels “by ear”, choose one speaker—usually the center— as a reference and
adjust each of the others in turn to “sound as loud” as the reference. Be sure that you remain in the
primary listening position while balancing all channels.
To produce the same SPL meter reading (or subjective loudness), use the remote’s [ ] keys to
adjust each speaker.
OPERATION
USING THE T 175 SETUP MENU
NOTES
• All speakers must be in their nal locations before level-setting.
• Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to
its highest-possible frequency if you are using the T 175's Subwoofer output. Final subwoofer-level
adjustment “by-ear,” using music and lm sound material, is frequently useful.
• Due to the eects of room acoustics, matched-pair speakers (front; surround; back) will not always
calibrate to exactly the same level oset readings.
You can exit “Test” mode at any time by pressing the [ ] key twice, bringing you back to “Speaker
Setup” menu.
SPEAKER DISTANCE
Your system’s speaker distance settings are a subtle but important renement of your setup. Informing
the T 175 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct
delays, optimizing imaging, intelligibility and surround-sound ambience. Enter your dimensions with
precision within about 1 foot (30 cm).
SETTING SPEAKER DISTANCE
While at “Speaker Distance” menu, use the [ ] keys to individually set Front Left, Center, Front Right,
Surround Right, Back, Surround Left and Subwoofer to the distance measuring from your principal
listening position to the front surface of their corresponding loudspeakers. Distance can be set up to
30 feet or 9.1 meters.
Distance can be displayed as feet or meters selectable at the “Unit of Measure” item.
ADJUSTING THE VOLUME
In addition to the Volume knob, use the HTRC 1’s [VOL ] to adjust the “master volume” of the T 175
raising or lowering the channels altogether. A momentary keypress will change the master volume by 1 dB
increments. If you hold down [VOL ] the master-volume change will “run-on” until the key is released.
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
Since recordings vary considerably in overall average level, there is no imperative to listen at any
particular master-volume setting. A setting of -20 may sound “as loud” from one CD or DVD as -10 does
from another.
The T 175 will power-up from Standby mode at whatever master volume setting was last used;
however, if the prior setting was greater than –20 dB, the T 175 will power up at –20 dB. This prevents
inadvertently beginning a session at excessive volume.
MUTING THE SOUND
Use the HTRC 1’s “Mute” key to silence all channels completely. Muting is always available regardless of
the source or listening mode selections.
NOTES
• Changing input or listening-mode selections does not release muting.
• Adjusting the master-volume upward via the HTRC 1 or the front-panel knob automatically releases

ADJUSTING CHANNEL LEVELS “ON THE FLY”
You can make changes to the relative levels of center, surround and subwoofer outputs without
having to go into the “Speaker Levels” menu. This is very convenient in circumstances like increasing
(or tone down) a lm’s dialog level by rising (lowering) the center channel or reducing excessive deep
bass (or enhance deep bass) by lowering (rising) the subwoofer level.
Use the HTRC 1’s [SURR], [CENT] and [SUB] keys for direct-access level adjustment of these channels
over a range of ±6 dB.
The surround back channels (if any) adjust in lockstep with the surround channels.
NOTE
Level settings adjusted “on the y” are added or subtracted to the setup levels established at the
T 175 level-calibration routine as invoked by the HTRC 1 “Test” key. However, selecting any Preset
will revert the channel levels to those stored in the preset. It will also take T 175 o the levels set via
Audyssey Auto Calibration.
ZONE SETUP
The Zone feature allows one to simultaneously experience in dierent zones of the house multiple
sound and applicable video sources from all enabled Sources as well as from Front Input, Media Player
and Tuner.
The T 175 has three congurable Zones – Zone 2, Zone 3 and Zone 4. Use a combination of [ ] or
[ENTER] and [ ] keys to navigate through the Zone Setup menu parameters.
VOLUME
Zone 2 have Fixed and Variable volume control. When set to “Variable”, the Zone 2 Volume is directly
adjustable using [ ] cursor keys of the HTRC 1 or [Volume ] keys of ZR 4.
On the other hand, if Volume is set to “Fixed”, the Zone 2 Volume is set to a preset dB level and thereafter
the zone’s volume can be varied via the volume control of the separate amplier it is fed into.
MODE
Zone 3 and Zone 4 can be congured into two modes – Record Out and Zone (Audio Only). If the
selected mode is Record Out, the audio and applicable video signal of the assigned Source are directly
sent out to the applicable Audio/Video Output (See Item 11. AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4
OUT/VIDEO 4 OUT of REAR PANEL discussion.) When Zone 3 or Zone 4 is set to “Record Out” mode,
they will not be available at the “Zone Controls” section of the Setup Menu window.
“Record Out” setting is ideal for making recordings with a VCR or other similar devices. This setting is also
used for multi-zone installations using passive “impedance matching” volume controls. See your NAD dealer
for specic information about integrating your T 175 into a multi-room audio distribution system.
Zone 2 and Zone 3 “Volume” will function the same way as that of Zone 2 when “Mode” is set to “Zone
(Audio Only)”.
See discussion also on “Zone Controls” at the Main Menu.
NOTE
The ZR 4 remote control will only control Zone 2 applications.
TRIGGER SETUP
The T 175 features three congurable +12V DC Trigger Output that can be used to activate a
component or system it is fed into. A Trigger Input is also available to turn on the applicable link it is
associated to. Use a combination of [ ] or [ENTER] and [ ] keys to navigate through the Trigger
Setup menu parameters.
TRIGGER OUT
Triggers are low voltage signals used to turn on/o other compliant devices. The T 175’s three +12V DC
Trigger Outputs (Trigger 1 Out, Trigger 2 Out and Trigger 3 Out) are dependent on which mode they
are associated with. There are six choices where +12V DC output can be assigned and these are – Main,
Zone 2, Zone 3, Zone 4, Zone 2+3+4 and Source Setup.
Main: +12V DC is available at the assigned Trigger Out when the T 175 is at powered state.
Zone 2, Zone 3, Zone 4, Zone 2+3+4: When the applicable Zone is at powered state, +1 2V DC
is available at the assigned Trigger Out.
Source Setup: If Trigger Output is linked to “Source Setup”, +12V DC is available at Trigger Out
whenever the particularly assigned Source is selected. Please see also separate discussion about
“TRIGGER OUT” under the “Source Setup (Normal View)” section.
DELAY
The availability of +12V DC at Trigger OUT can be regulated. If it is desired that +12V DC is available
without delay the moment Trigger OUT is linked to its assigned setting, set Delay to 0s. Otherwise, one
can select through a delay time of 1s to 15s.

reproduce a variety of sound eects depending upon the content of the source to be played. Use a
combination of [ ] or [ENTER] and [ ] keys to congure the following settings.
LISTENING MODES
The audio format as detected by the selected Source can be automatically congured and processed
through the following options:
DOLBY DIGITAL
Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs
bearing the double-D symbol were recorded with up to 5.1 channels of digital signals, reproducing a
much better sound quality, with dynamic and spatial sound sensations that are much better than in
the previous Dolby Surround.
A Dolby Digital audio input can be congured relative to its format.
2 Channel: If the detected audio is a 2 Channel Dolby Digital signal, you can default it to one of
the following settings – Pro Logic, PLIIx Movie, PLIIx Music or None.
Surround: If the detected audio is a Surround Dolby Digital signal, you can default it to one of the
following settings –Surround EX, PLIIx Movie, and PLIIx Music, Stereo Downmix or None.

DOLBY DIGITAL EX
Using a Matrix decoder, this method creates the back channel (sometimes also called the “surround
center”) by means of signals on the left and right surround channels recorded in Dolby Digital 5.1,
reproduction being provided in Surround 6.1. This method should be selected with sources bearing
the (double-D symbol)-EX, recorded in Dolby Digital Surround EX.
With this additional channel you will experience improved dynamics and a better sensation of
movement within the sound eld. If media sources recorded in Dolby Digital EX are decoded with a
Digital EX decoder, the format is detected automatically, and the Dolby Digital EX mode is selected.
However, some media sources recorded in Dolby Digital EX can be detected as simple Dolby Digital
media sources. In this case Dolby Digital EX should be selected manually.
NOTE
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of Pro
Logic, PLIIx Movie, PLIIx Music and Stereo Downmix modes.
DTS
The Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format
that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are
5.1 channel media formats, discs bearing the “DTS” symbol are thought to provide better sound quality
due to the lower audio compression required. It also oers a broader dynamic, producing magnicent
sound quality.
A DTS input can be defaulted to one of the following options: - Neo:6 Music, Stereo Downmix or None.
If “None” is selected, the DTS signal will follow the “Digital” setting set forth at “Other” option under this
menu section. See discussion below about “Other”.
NOTE
Please refer to the section “LISTENING MODE” at the Main Menu discussions for a description of
Stereo Downmix and DTS Neo:6 surround modes.
OTHER
If “None” is selected above for any of the Dolby Digital 2 Channel, Dolby Digital Surround and DTS
options or if the audio input is an analog signal, this “Other” section will manage the default audio
format as per the “Digital” or “Analog” settings.
Digital: The detected digital input can be congured by way of one of the following options
- Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced Stereo, Stereo
Downmix and None.
Analog: If the audio input is an analog signal, the following are the surround modes the input
can be defaulted - Pro Logic, PLIIx Movie, PLIIx Music, Neo:6 Cinema, Neo:6 Music, EARS, Enhanced
Stereo, Analog Bypass and None.
NOTE
All these Listening Modes for “Dolby Digital”, “DTS” and “Other” can be directly changed by pressing
the “LISTENING MODE” button on the front panel or through the “Listening Mode” option at the
Main Menu window. The chosen audio format will be reected back to the appropriate setting at
the “Listening Mode Setup”.
DOLBY SETUP
Under this menu, the Dolby Digital’s Dynamic Range Control can be adjusted as well as the settings for
Dolby Digital Pro Logic IIx Music.
Dynamic Range Control: You can select the eective dynamic range (subjective range from soft
to loud) for playback of Dolby Digital soundtracks. For fully cinematic eect, 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.
The 25% setting will yield the least dynamic range and is best for late-night sessions or other times
when you wish to retain maximum dialog intelligibility while minimizing overall volume levels.
Dolby Pro Logic IIx Music: Please refer to the same description about “ADJUSTING LISTENING
MODES” under the “LISTENING MODE” of the Main Menu discussions.
DTS SETUP
Under this menu, the Dynamic Range Control of DTS Digital Surround can be adjusted as well as the
settings for DTS Neo:6 Music.
Dynamic Range Control : This is the same congurable Dynamic Range Control feature as
described above at Dolby Setup, the only dierence being the soundtrack is now in DTS format.
DTS Neo:6 Music : Please refer to the same description about “ADJUSTING LISTENING MODES”
under the “LISTENING MODE” of the Main Menu discussions.
DTS SURROUND MODES
The following are further descriptions about the DTS surround modes.
DTS ES EXPANDED SURROUND ™ DTS ES
This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the
Surround impression thanks to the greater space expansion of the surround signals, providing high
compatibility with the conventional DTS format.
In addition to the 5.1 channels, the expanded DTS-ES Surround also oers the back surround (also
sometimes called the “surround centre”) in reproduction, providing a total of 6.1 channels. The
expanded DTS-ES Surround includes two formats, with two dierent methods of surround signal
recording, as follows:
OPERATION
USING THE T 175 SETUP MENU
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
DTSES™ DISCRETE 6.1
Since the signals of the 6.1 Surround channels (including the back channel) are completely
independent, it is possible to achieve the sensation that the acoustic image is moving about freely
among the background sounds, 360 degrees surrounding the listener.
Although maximum quality is achieved with sound tracks recorded using this system and reproduced
using the DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel
is automatically downmixed in the surround right and surround left channels of the surround system,
in such a way that none of the signal components are lost.
DTS ES™ MATRIX 6.1
In this format, the additional signals of the back channel receive a matrix encoding and are inputted
into the right and left surround channels. During reproduction they are decoded to the right, left and
back surround channels.
Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1
format eect can also be achieved from sources with DTS-ES 5.1 signals.
Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in
DTS–ES 6.1.
When a DTS-ES decoder processes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats are
automatically detected and the Optimum Surround mode is selected. However, some DTS-ES Matrix
6.1 sources may be detected as DTS. In this case the DTS-ES Matrix mode should be selected manually
in order to reproduce them.
DTS NEO:6™ SURROUND
This mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to
the high precision digital matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-channel surround
playback. DTS Neo:6 surround includes two modes for selecting the optimum decoding of the signal
sources:
DTS NEO:6 CINEMA : This method is ideal for the reproduction of movies. The decoding takes
place by emphasizing the separation in order to achieve the same atmosphere with 2-channel, as
with 6.1-channel sources.
DTS NEO:6 MUSIC : Mainly recommended for music reproduction. The right and left front
channels do not pass through the decoder and are reproduced directly so there is no loss in sound
quality, and the eects of the right surround, left surround, central and back surround channels add
a natural sensation of expansion of the sound eld.

LISTENING TO RADIO
The T 175’s internal AM/FM tuner oers very high quality sound from radio broadcasts. The reception
and sound quality will always be dependent to a degree however on the type of antenna(s) used as
well as proximity to the broadcast origin, geography and weather conditions.
ABOUT ANTENNAS
The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the
included “balun” adapter and should be fully extended to form a “T”. This folded-dipole antenna will usually
work best when oriented vertically, with the arms of its “T” fully outstretched and arranged perpendicular
to the origin of the desired broadcast. There are no rules however, and experimenting freely with antenna
placement and orientation may yield the clearest sound and lowest background noise.
In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If
radio listening is important to you, consider consulting an antenna installation professional to
optimize your system.
The supplied AM “loop” antenna will usually provide adequate reception. However, an exterior AM
antenna can be used to improve reception. Consult an antenna professional for more information.

USING THE T 175 AM/FM/DB/iPod
ABOUT DAB RADIO
Until now, analogue radio signals such as FM or AM have been subject to
numerous kinds of interference on their way from the transmitter to your
radio. These problems were caused by mountains, high-rise buildings
and weather conditions. With Digital Audio Broadcast (DAB), you can now
receive CD-like quality radio programs without any annoying interference
and signal distortion. DAB broadcasts use digital signals rather than
traditional analogue transmissions, thus providing clear high quality
reception. You get far more robust reception and virtually hiss or crackle
free sound with DAB as long as you are within a good coverage area.
With DAB, the listener can scroll through a list of available stations - then
instantly tune to the station of his choice. There is no need either to
remember channel frequencies. All broadcasts are selected by simply
selecting the service name.
The T 175 makes it possible for you to enjoy listening to DAB broadcasts.
The T 175 has a Digital Audio Broadcast (DAB) module socket on the rear
panel for adding a separately sold and NAD-specied outboard DAB
module – the NAD DAB Adaptor DB 1. All the control software for this
format is included; just plug-in the module and start enjoying the CD-like
quality sound and expansive content selection available with DAB.
CONNECTING THE DAB MODULE
Plug-in the other end of the DIN connector (supplied with your NAD DAB
Adaptor DB 1) from the DAB module’s output port into the corresponding
DAB module input socket on the rear panel of the T 175. Select DAB mode
on the T 175 by toggling the [AM/FM/DB] button in the front panel.
NOTES
• Please refer to NAD DAB Adaptor DB 1 installation guide for proper setup
connection of the DB1 with respect to the T 175.
• If there is no NAD DAB Adaptor DB 1 connected, the VFD will show
“Check DAB Tuner”.
The bars show the progress of the sequence. When scanning is
completed, the last number shown on the right side of the VFD
corresponds to the total number of DAB broadcast stations found. Then,
the rst station is tuned in (See “ALPHANUMERIC” section below to
understand the order or arrangement of stations).
4 The strength of the incoming signal can be shown on the VFD by
pressing the [ENTER] button. The more segments visible in the lower
display line, the stronger the signal. By changing the position of the
antenna, you can increase the signal strength. You can also opt for an
external antenna. Consult an antenna professional for more information.
NOTES
• “No Service List” will also be shown in the VFD when no stations are
found after the scanning process. If this occurs, check the connection
and position of the DAB antenna or call your local DAB broadcast
providers for coverage information.
• HTRC 1’s [MENU/FM MUTE], [ENTER] and [ ] are the equivalent
remote control keys for the front panel buttons [TUNER MODE], [ENTER]
and [TUNE / ]. When using these HTRC 1 buttons to navigate
DAB options, ensure that the “DEVICE SELECTOR” setting of your HTRC 1
is set to “TUNER”.
SERVICE LIST
Follow the steps below to select through the DAB service stations found.
1 At DAB mode, press [TUNE / ] to step through the list of available
stations as shown in the lower display line of the VFD.
DAB OPERATION
With the separately sold NAD DAB Adaptor DB1 already connected to the
T 175, you can now carry out the T 175 to receive DAB broadcasts.
1 Toggle [AM/FM/DB] button until DAB mode. The VFD will show “No

USING THE HTRC 1 REMOTE CONTROL
IDENTIFICATION OF CONTROLS
• Top section features ON/OFF buttons and back-light LCD display.
• Upper section has eight DEVICE SELECTOR keys including one programmable CUSTOM DEVICE
SELECTOR key and an additional MACRO button function key.
• The upper middle section with channel, volume, MUTE, and surround mode buttons.
• Middle section has DVD, CD, TUNER and OSD navigation buttons.
• Lower middle section has number buttons 0 to 9, A/V PSET, SPEAKER and CD functions, DVD
SETUP, and tuner-preamplier’s TEST and DELAY buttons.
• Lower section has DVD and CD transport buttons, tuner-preamplier audio function keys as well as
DVD resolution button.
• Bottom section with CHANNEL VOLUME trimming buttons.
INTRODUCTION
The HTRC 1 is like having eight virtual remote controls in one. The eight DEVICE SELECTOR keys can be
used to switch between the dierent virtual remote controls or devices.
When the HTRC 1 is idle, the name of the currently selected device will be shown on the rst line
of the LCD display. Whenever a function key is pressed, the name of that function will be shown on
the second line of the LCD display. The second line will be cleared again shortly after releasing the
function key.
HIGHLIGHTS
• Controls up to 8 Devices.
• 2-line LCD display indicates selected Device (DVD) and sent Command (PLAY ) (for example).
• Preprogrammed with all NAD remote commands including Zone 2.
• Learning function - learns up to 360 commands from other remotes.
• Macro operations - program up to 52 Macros with as many as 64 commands each to automate
commonly used command sequences.
• Punch Though Operations permit easy access to commonly used functions without reselecting a
device.
• Full illumination with light sensor and adjustable time out for easy operation in low light
conditions.
• Can generate IR signals with a carrier frequency up to 500 kHz (B&O® compatible).
• Mini USB PC Interface allows programming from a Personal Computer.
The HTRC 1 is already preprogrammed with a full complement of NAD commands on its AMP DEVICE
SELECTOR page, and with library commands to operate most NAD DVD, CD and TUNER components
on the corresponding DEVICE SELECTOR keys. These default commands are permanent: Even if you
teach the HTRC 1 new commands to take their place, the underlying library commands remain in
place and can easily be recalled should you add an NAD component to your system later.
GETTING FAMILIAR WITH THE HTRC 1
The HTRC 1 is divided into three main sections. The LCD display section at the top of the handset, the
DEVICE SELECTOR, and the remaining 44 Control keys.
Eight DEVICE SELECTOR keys at the top; AMP, TV, CUSTOM, CD, DVD, VCR, TUNER, and CABLE/SAT
determine which component the remaining 44 control keys will operate. A DEVICE SELECTOR key
determines what component the HTRC 1 will command; with factory defaults, it does not perform any
function on the T 175. The DEVICE SELECTOR keys are organized into three vertical rows of 3 buttons
each; the row on the left are all Audio devices, the row in the center are all Video devices.
Both the DEVICE SELECTOR and function keys can “learn” control codes from virtually any infrared
remote controller, allowing you to teach the codes of your equipment, regardless of brand, to the
HTRC 1. All of the function keys on the AMP DEVICE SELECTOR are preprogrammed to control NAD
ampliers, preampliers, and receivers. (The HTRC 1 can also command many other NAD components,
from its DVD, CD, TUNER and TV pages.)
Since HTRC 1 Control keys can perform dierent functions, depending on the selected DEVICE
SELECTOR key, the HTRC 1 uses color coding to indicate the function of the function keys when
dierent device keys are chosen. Thus, the colour of the DEVICE SELECTOR key-labeling corresponds to
the labeling of the function keys (similar to a calculator).
OPERATION
USING THE HTRC 1 REMOTE CONTROL
For example, the grey AMP DEVICE SELECTOR key label corresponds to the
grey input-select labeling adjacent to the numeric keys: When the HTRC
1’s AMP DEVICE SELECTOR page is active, these keys select the amplier
or receiver inputs. Similarly, the red DVD DEVICE SELECTOR key label
corresponds to several red labels, the green TV DEVICE SELECTOR key to
green labels, and so on.
NAVIGATION OF THE HTRC 1 CONTROLS
DEVICE SELECTOR KEYS
Simply pressing a DEVICE SELECTOR key will change the active device on
the HTRC 1. At this time, no IR commands will be transmitted. The name of
the selected device will be shown on the rst line of the LCD display.
NOTE
Any IR command can be associated with a DEVICE SELECTOR key during
“Copy” and “Learn” modes. Once the associated function is assigned to
the DEVICE SELECTOR key, pressing and holding the DEVICE SELECTOR
key for more than two seconds will send the associated command in
addition to the HTRC 1 switching its active device.
MACRO KEYS
A macro can be associated with every key on the HTRC 1 except for the
MACRO button itself. A total of 52 macros can be stored. To execute a macro:
• Press the MACRO key. The rst line of the LCD display will show “MACRO.”
Within ve seconds, press the key the macro is associated with.
• While the macro is executing a small "M" will be shown in the top right
of the LCD display.
HTRC 1 SETUP MENU
GENERAL MENU OPERATION
• Press and hold SETUP + ENTER for 5 seconds to enter setup menu.
• The MACRO key is a cancel function in all setup modes unless otherwise
noted.
• You can exit menus by selecting “Exit” or pressing the MACRO key.
• Use [ ] cursor keys to select dierent menu
• For options which can be changed, the Right and Left keys are used to
cycle through the available options. Left and Right arrows will be shown
on the display to indicate when an option can be changed.
• Press ENTER to select a menu option or conrm a value.
• While a setup menu page is being executed, the corresponding rst
letter of the selected setup feature (i.e. “L” when “Library” is the selected
SETUP) is shown in the upper right corner of the display.
The following are the SETUP menu parameters.
BATTERY
Instead of waiting until the “Low Batt” warning is displayed, you can check
the current battery level using this option. This option will show a bar graph
representing the current battery level. When the batteries are new, the bar
graph will show 8 bars. Once the bar graph reaches close to zero, the “Low
Batt” warning will start to show.
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
Refer also to the “MACRO” item below of the “HTRC 1 SETUP MENU” section
for information on how to setup macros.
FUNCTION KEYS
There are 44 dedicated function keys on the HTRC 1. When you press a
function key, the name of the function will be shown on the second line of
the LCD display while the command is being transmitted.
A/V PSET KEY
In the default conguration of the HTRC 1, the A/V PSET key acts as a shift
function when the AMP device is selected. Pressing the A/V PSET key
once will cause “Preset” to be displayed on the rst line of the LCD display.
If within ve seconds you then press a digit (0 – 9), the function for the
corresponding A/V Preset will be transmitted.
NOTE
The HTRC 1 is a universal-type remote control; some NAD receivers may
not have more than 5 AV presets.
SOFTWARE VERSION NUMBER
Press simultaneously the ON + TEST buttons for ve seconds to display
version numbers.
SETUP MENU
Press and hold the SETUP and ENTER keys for ve seconds to enter the
Setup Menu. You cannot enter the setup menu if the remote is currently

corrupted under low battery conditions. Please refer to “HTRC 1 SETUP
MENU” section below for the overall structure and basic operation of the
Setup Menu.
LOW BATTERY WARNING
If the HTRC 1 senses the batteries are low, it will show “Low Batt” on the
second line of the LCD display whenever the remote is idle. When this
occurs the batteries should be replaced with new ones immediately.
BACK LIGHT SENSITIVITY (B LIGHT)
The HTRC 1 is equipped with a backlight to increase visibility of the HTRC 1
in low light conditions. The HTRC 1 also includes a light sensor. By default, if
you press any key on the remote and it senses a low light condition, the back
light will turn on. It will then turn o again ve seconds after no key has been
pressed. The behavior and timeout for the backlight can be adjusted.
TIMEOUT: The backlight timeout can be set from 0 - 20 seconds. This is the
length of time the backlight stays ON after releasing the last key.

8 Use [ ] to select between “No” (desired function key will not be
copied) and “Yes” (desired function key will not be copied and process is
completed).
NOTE
The copy and punch-through functions are similar. However, if you copy a
command and then subsequently delete, or over-write the original (sourcekey) command, the copied-to key’s command remains unchanged. If you
punch-through to a command and then delete or over-write the original
key, the punched-through functions also change accordingly.
Refer also to the “MACRO” section below for information on how to setup
macros.
OPERATION
USING THE HTRC 1 REMOTE CONTROL
DELETE
Each key can have several functions types stored. However, only the highest
priority type will be active. When you delete a function, a lower priority
function type may become active. To completely erase the functionality
of a key, you may need to execute the Delete function multiple times. For
example; if you delete a learned command, a lower priority command may
become active. The order of priority for each function type is:
1 Punch Through
2 Learned
3 Copied Library Command
4 Default Library Command
Example: Delete punch-through “SURR MODE” function key from DVD
page (refer to PUNCH-THROUGH example above).
1 Press [DVD] in the DEVICE SELECTOR page.
2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use [ ] to
scroll to “Delete”.
3 Press [ENTER].
4 Press [SURR MODE] button.
5 Use [ ] buttons to select the rst character of the name (“D” from
the alphabetical list).
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
6 Press [ ] button to select the character and correspondingly move
forward to the next position. (Press [ ] to go back to the previous
character). Repeat this process for each character in sequence.
7 Since “DVD” is only three characters and “Input 1” is six character spaces,
overlap the remaining characters with a space. Space or blank can also
be selected using [ ] buttons – scroll up to the blank character.
8 Press [ENTER] when you have nished the renaming sequence.
9 Display shows “Save” and “No” - use [ ] to select between “No” (new name
will not saved) and “Yes” (new name will be saved and process is completed).
MACRO
A “macro” command is a series of two or more remote codes issued
automatically from a single keypress. You might use a macro to automate
a simple command sequence, such as, “ Turn on the DVD player and then
press “play.’” Or you might compose an elaborate macro to power up
an entire system, select a source, choose a Listening Mode, and begin
playback—again, all from a single keypress. The HTRC 1 can store one
macro to all its function keys except MACRO.
5 Use [ ] to select between “No” (desired function key will not be
deleted) and “Yes” (desired function key is deleted and process is
completed).
RENAME
All keys can be renamed except MACRO key.
Example: Rename “Input 1” key of “AMP” page to “DVD”.
1 Press [AMP] in the DEVICE SELECTOR page.
2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use [ ] to
scroll to “Rename”.
3 Press [ENTER].
4 Press [1] button.
Macros will be executed with the same timing as they were recorded. The
length of time each command is sent will also correspond to the same
length of time the key will be held down while recording.
Example: Record a Macro to the [0] key to turn ON the NAD T 175, Select
[Input 1], turn ON the NAD T515 DVD Player, and commence disc playback
of the connected Input 1 device (as in the NAD T515 DVD player):
1 Press [AMP] in the DEVICE SELECTOR page.
2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use [ ] to
scroll to “Macro”.
3 Press [ENTER].
4 Display shows “Macro” and “Key?”- press [0].
5 Press [AMP], [ON], [1], [DVD], [ON] and [ ](Play). The length of time
each command is entered will also correspond to the same time
sequence the macro command is executed.
6 Press [MACRO] to end the sequence.
7 Use [ ] to select between “No” (macro command will not be saved)
and “Yes” (macro command will be saved and process is completed).

USING THE HTRC 1 REMOTE CONTROL
EXECUTING MACRO
To execute the above macro example, press [MACRO] and then [0].
The corresponding macro will run; the display will show each step/
command as the macro is executed. Pressing any other HTRC 1 key while a
macro is executing will abort the macro.
USB INTERFACE
The HTRC 1 allows one to upload and download the conguration through
a Windows PC and NAD’s Proprietary HTRC 1 programming software. Use
a USB A male to mini USB B male 5-pin cable (not supplied) between your
Windows® PC and the HTRC 1. See illustration below on how to connect a
USB A male to mini USB B male 5-pin cable to the HTRC 1.
NOTE
Please log onto www.nadelectronics.com for the latest HTRC 1 interface
control software. Your custom installer or dealer can assist you in the
proper setup and conguration of the mini USB interface and software.
By default, when a macro is executed, the currently selected device will be
returned to what it was before the macro was executed. However, if the
very last button pressed while recording a macro is a DEVICE SELECTOR key,
the device will be changed at the end of executing the macro.
RESET
Selecting this option and answering “Yes” to both conrmations will reset all
HTRC 1 options to the factory default. All user congurations, macros, and
custom device programming will be erased.
1 Press [AMP] in the DEVICE SELECTOR page.
2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use [ ] to
scroll to “Reset”.
3 Press [ENTER].
4 Use [ ] to select between “No” (HTR C1 will not be reset) and “Yes”
(HTR C1 will be reset to its factory defaults). When you select “Yes”,
another prompt display will be shown.
5 Select “Yes” to reset the HTR C1 and complete the process.
OPERATION
USING THE HTRC 1 REMOTE CONTROL
BATTERY INSTALLATION
Press in and lift tab to remove battery cover out from recess
Place batteries into opening. Ensure the correct polarity is observed
SLEEP MODE
The Sleep Mode timer will switch the T 175 to Standby mode automatically
after a preset number of minutes. Pressing the HTRC 1’s SLEEP button once
will display the setting of the sleep time increment. Pressing the HTRC 1’s
SLEEP button a second time within a 3-second period will change the
sleep time increment in 15-minute intervals, after which time the T 175 will
automatically switch into Standby mode.
To adjust the sleep delay, press the HTRC 1’s SLEEP button twice; rst
to display the sleep time increment, and a second time to change the
sleep time increment. The sleep time increment and a “SLEEP” icon will
continuously display on the T 175’s front panel Vacuum Fluorescent Display
(VFD). Each consecutive press increases the sleep time in 15-minute
increments from 15 to 90 minutes. To cancel the sleep mode, continue
pressing the HTRC 1’s SLEEP button until “SLEEP OFF” displays on the VFD.
Switching the T 175 to standby from either the HTRC 1’s OFF or the T 175’s
POWER button will also cancel the sleep mode
USING THE ZR 4 REMOTE CONTROL
The ZR 4 remote control is a discrete compact remote for controlling the
T 175 from various rooms other than the main room. The ZR 4 remote
allows full separate control of the source selection irrespective to the main
room. This means the zone input may be completely dierent, audio and
video, from the main input and thus corresponding volume levels as well.
If one wishes to enjoy the same source, as the main room the ZR 4 remote
has a [LOCAL] button to allow simultaneous listening, but with full separate
volume levels.
ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
Press battery cover into place until it ‘clicks’ closed
To mute the Zone Volume level, press [MUTE] on the ZR 4. If the “Zone
Controls” OSD menu is ON, the Zone “Volume” level section will display “Mute”.
The T 175’s front orescent display will show activity of the zone control
so that main room occupants are aware of the zone remote activity.
Furthermore if there is no main room activity, only the zone indicator will
be active in the T 175’s uorescent display.
NOTE
The ZR 4 remote control will only control Zone 2 applications. 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. The HTRC 1’s
“CUSTOM” device is also defaulted to Zone 2 remote control codes.
