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

line-level audio sources like a CD player or Stereo tuner.
10 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.
11 AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4 OUT/VIDEO 4 OUT: Connect
the T 175’s AUDIO 3 OUT/VIDEO 3 OUT or AUDIO 4 OUT/VIDEO 4 OUT
jacks to the analog audio/video input of a recording component
such as a cassette deck, DVD recorder or to an outboard audio/video
processor. Connect the T 175’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 175 AUDIO/VIDEO OUT jacks is determined
by the source last selected via the front panel Source keys or the
HTRC 1’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.
When congured, AUDIO 3 OUT/VIDEO 3 OUT and AUDIO 4 OUT/VIDEO
4 OUT are the same assigned ports for Zone 3 and Zone 4 respectively.

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,

ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA РУССКИЙ
PRO LOGIC
Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro
Logic surround processing, yielding output to front left/right, center and discrete left/right surround
channels (assuming these are present in the current “Speaker Conguration”). The surround channel is
monophonic, but it is reproduced in both surround speakers.
PRO LOGIC PLII
Dolby Pro Logic II is a more recent evolution of the original Dolby Pro Logic surround processing that
yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, oering
sound that is more similar to Dolby Digital decoding.
PRO LOGIC IIx
Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby
Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience
to the source material. Dolby Pro Logic IIx surround processing yields more stable imaging and
full bandwidth sound to the rear channels in Movie mode oering sound that is more similar to
Dolby Digital decoding. For two channel signals, Dolby Pro Logic IIx Music mode also features three
additional user controls - Dimension, Center Width, and Panorama. See also section about “ADJUSTING
LISTENING MODES” below.
The following chart shows the channels available assuming they are enabled in the “Speaker
Conguration” menu;

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.

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 your personal preferences. At Listening Mode menu, use a
combination of the [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
“O” from “Speaker Congurations” menu. See also section about “SPEAKER CONFIGURATIONS”
under “SPEAKER SETUP” of the Setup Menu.
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.
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
T 175. If “O” (Tone Active in the VFD) is selected, the Tone Control circuits are active.
Select “On” to bypass the Tone Controls eectively defeating the eect of the tone control circuits.
