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 flexible 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 Preamplifier, 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 Preamplifier’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 flexible 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 artificially generated reflections

or regeneration. EARS’ natural ambience yields a subtle but exceptionally effective 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 effort NAD has invested in the T 175 AV Tuner Preamplifier’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 fine-tune your listening setup for different conditions, sources, or listeners, and to recall these multiple parameters with a single key press.

INTEGRATION

The T 175 AV Tuner Preamplifier offers extensive, flexible system-integration options through its configurable 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.

ZONE

The T 175 AV Tuner Preamplifier is equipped with three configurable 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/Off and all sources inputs. Zone 3 and Zone 4 could be configured 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 configuration is possible with the RS-232 interface and NAD’s proprietary Windows® compatible software. We are also certified partners with AMX and Crestron and fully support these external devices.

This interface allows complete remote control of the T 175 from any remote location via the PC. Complete remote control functionality is available to the user by interface software. See your NAD audio specialist for further information.

UPGRADABILITY

The T 175 AV Tuner Preamplifier permits flexible system growth via individually accessible pre-out and main-in jacks for all channels. We have made the more likely scenario of software upgrades easy to accomplish via the high speed RS-232 port on the rear panel of the T 175. Owners who register their T 175 on our international web site www.NADelectronics.com will be advised of updates. Some of these may be free of charge, and some may require royalty payments depending on the type of upgrade. The

advanced user will be able to perform these upgrades by downloading files from our web site, via e-mail and installing them by connecting the T 175 to a PC. Alternatively the dealer from whom you purchased your T 175 should be able to assist in performing these upgrades.

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 AV 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.

ATTENTION!

Please make sure that the T 175 is powered off or unplugged before making any connections. It is also advisable to power-down or unplug all associated components while making or breaking any signal or AC power connections.

17.1 CH INPUT: Connect to the corresponding analog audio outputs of a multichannel source component such as a DVD-Audio or multichannel-SACD player or external multichannel decoder (disc copy protected formats only allow analog signal transfer). Typically, these sources will produce 5.1-channel output, in which case the Surround Back jacks are left unconnected. The signals present at these jacks may be heard by selecting Source 7 (7.1 Channel Input is defaulted to this Source).

There is no bass-management or other processing (other than mastervolume control) available to this 7.1 Channel Input. While the multichannel audio outputs of a DVD-Video player can be connected to these jacks, using the T 175’s own Dolby Digital and DTS decoding and digital-analog converters via a digital connection will usually produce superior results.

2AUDIO PRE-OUT: The Audio PREOUT makes it possible to use the T 175 as a pre-amplifier to external power amplifiers for some or all channels. Connect FRONT L, FRONT R, CENTER, SURR R, SURR L, SURRBL, SURR-BR and CENTER to the respective channel input of a power

amplifier or an amplifier driving the corresponding applicable speakers.

Unlike the full range channels, there is no power amplifier built-into the T 175 for a subwoofer. Connect the SUBW 1 or SUBW 2 output or both to powered (“active”) subwoofers or to power amplifier channels driving a passive system.

3MP DOCK: The T 175 is equipped with a data port in the rear panel where an optional “NAD IPD 1 Dock with iPod” (NAD IPD 1) can be plugged in. Connect the “MP DOCK (DATA PORT)” jack of the T 175 to the corresponding “DATA PORT” socket of the optional NAD IPD 1.

4FM, AM ANTENNA INPUT: The supplied wire “dipole” FM antenna will connect to the FM connector using the supplied “balun” adapter. It will usually work best when mounted on a vertical surface such as a wall, with arms fully outstretched forming a horizontal “T” perpendicular to the origin point of the signal.

Connect the supplied AM loop antenna to these terminals. If an external AM antenna is used, make connections to the AM and GND terminals in accordance with the instructions supplied with the antenna. See also section about “LISTENING TO RADIO”.

5XM MODULE INPUT (North America version only): Connect XM radio cable to this socket. Follow the instructions that came with your XM radio. With XM radio, there are more than 100 channels of music, news, sports, comedy, talk and entertainment. You will find that the coverage is continent wide.

REAR PANEL

6RS-232: Connect this interface via RS-232 serial cable (not supplied) to any Windows® compatible PC to allow remote control of the T 175 through NAD’s proprietary PC software or other compatible external controllers. NAD is a certified partner of AMX and Crestron and fully supports these external devices. See your NAD audio specialist for more information.

7+12 V TRIGGER OUT: There are three configurable +12V TRIGGER OUTPUT. Use a 3.5mm mini-jack connector to pass +12 volts at a maximum current of 50 milliamps to auxiliary equipment such as a multichannel amplifier or subwoofer. The centre conductor (hot) of the 3.5mm jack is the control signal. The outside conductor (shield) is the ground return-path.

TRIGGER IN accepts 12V Trigger output of compatible components such as power controllers and home automation devices.

TRIGGER OFF/AUTO : When at AUTO position, the T 175 selects the 12V Trigger Input to turn ON (if so assigned at the “TRIGGER SETUP” menu) and at the same time disables the HTRC 1 and front panel’s ON/ OFF function. When set to [OFF] position, the trigger input is disabled.

See discussion on “TRIGGER SETUP” at the “SETUP MENU” literature for guidelines on how to configure TRIGGER IN/OUT.

WARNING

If Auto Trigger IN at Trigger Setup menu is assigned to “Main” or “All” and the TRIGGER switch is set to “AUTO” mode, the Power button in the front panel as well as the corresponding ON/OFF function keys in the HTRC 1 remote control will be disabled effectively handing this function to an external controller. Switch TRIGGER to “OFF” to maintain normal power ON/OFF function procedures.

8IR IN/OUT: These mini-jacks accept and output remote-controlled codes in electrical format, using industry-standard protocols, for use with “IR-repeater” and multi-room systems and related technologies.

IR IN : This input is connected to the output of an IR (infrared) repeater (Xantech or similar) or the IR output of another component to allow control of the T 175 from a remote location.

IR OUT 2 : When connected to the IR IN of an ancillary equipment, direct the ancillary equipment’s own remote control to the T 175’s infrared receiver to command or control the linked unit.

IR IN and IR OUT 3 : Connect the T 175’s IR IN to the IR OUT of an ancillary equipment. Connect also the T 175’s IR OUT 3 to another equipment with IR IN feature. With this setup, the T 175 acts as an “IRrepeater” allowing the equipment connected to the T 175’ s IR IN control or command of the other equipment linked to the T 175’s IR OUT 3.

IR OUT 1 : In conjunction with IR IN, IR OUT 1 can be used as an “IRrepeater” just like the IR OUT 3 as described above. It can also stand alone as an IR OUT similar to that of IR OUT 2 function.

All NAD products with IR IN/IR OUT features are fully compatible with the T 175. For non-NAD models, please check with your other product’s service specialists as to their compatibility to the T 175’s IR features.

9AUDIO 1 IN/VIDEO 1 IN, AUDIO 2 IN/VIDEO 2 IN, AUDIO 3 IN/VIDEO 3 IN, AUDIO 4 IN/VIDEO 4 IN, AUDIO 5 IN/VIDEO 5 IN, AUDIO 6 IN : These comprise the T 175’s principal input. Connect S-Video, composite video, and analog stereo audio from source components such as DVD players and HDTV/satellite tuners.

AUDIO 3 IN/VIDEO 3 IN, AUDIO 4 IN/VIDEO 4 IN may be used with recording components such as videocassette or DVD-recorders by connecting these components’ record-inputs to the corresponding T 175 AUDIO 3 IN/VIDEO 3 IN or AUDIO 4 IN/VIDEO 4 IN jacks. AUDIO 3 IN/VIDEO 3 IN or AUDIO 4 IN/VIDEO 4 IN may freely be used for play-only components, in which case their OUT jacks would remain

unconnected. Refer also to AUDIO 3 OUT/VIDEO 3 OUT, AUDIO 4 OUT/ VIDEO 4 OUT discussion below.

AUDIO 6 IN is advisable to connect to dedicated analog output from line-level audio sources like a CD player or Stereo tuner.

10MONITOR (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.

11AUDIO 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 configured, 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. See also Zone output description below.

12ZONE 2, ZONE 3, ZONE 4: Sends zone selected audio and video output sources to the corresponding audio and video input of another separate zone. Use high quality patch cables to reduce noise pickup over long distance runs. For a better understanding of zone settings, study below the section on “ZONE CONTROLS”of the “MAIN MENU”discussion as well as the item on “ZONE SETUP”under the “SETUP MENU”literatures.

NOTE

The ZR 4 remote control will only control Zone 2 applications. Zone 3 and Zone 4 could be configured and managed at the appropriate Zone OSD menu using the front panel navigations buttons as well as the corresponding keys on the HTRC 1 remote control.

1Press [] or [ENTER] to select a menu item. Use [] keys or in some cases, [ENTER], to move up or down the Menu selections. Repeatedly press [] to advance or go further into sub-menus of a desired menu item.

2Use [] keys to set or change the parameter value (setting) of a menu item.

3Press [] to save the settings or changes done on the current menu or sub menu. Pressing [] will also return the user to the previous menu or exit from a particular menu.

MAIN MENU

The Main Menu contains the menu options for “Listening Mode”, “DSP Options”, “Tone Controls”, “Zone

Controls” and access to “Setup Menu”.

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 configurations 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 offers nine distinct listening modes, tailored for different 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 Preamplifier only and therefore has no Speakers. The mention of “Speaker(s)” in this manual refers to your external amplifier’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.

OPERATION

USING THE T 175 – MAIN MENU

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 Configuration”). 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, offering 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 offering 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 Configuration” menu;

Listening Mode	Active Decoded Output Channels
Two-Channel Sources	6.1 Speaker System	7.1 Speaker System

	Front (left & right), Center,	Front (left & right), Center,
Dolby Pro Logic IIx Music	Front (left & right), Center,	Surround (left & right)
Dolby Pro Logic IIx Music	Surround (left & right),	Surround (left & right)
Dolby Pro Logic IIx Movie	Surround (left & right),	and Back Surround (left
Dolby Pro Logic IIx Movie	Back Surround, Subwoofer	and Back Surround (left
	Back Surround, Subwoofer	and right) and subwoofer
		and right) and subwoofer

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 Configuration”). 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 Configuration”). 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 configured in the current “Speaker Configuration”. 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 effect as these are DSP functions.

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 affect 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 -the-fly, 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] ] 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 “Off” (Tone Active in the VFD) is selected, the Tone Control circuits are active.

Select “On” to bypass the Tone Controls effectively defeating the effect of the tone control circuits.

An audio input and video input should always be associated to a selected Source setting to ensure audio and video output. If “Off” is selected for any of the Analog Audio, Video or Digital Audio settings, there will be no corresponding audio or video for the associated Source. For example, if the selected Video setting for a particular Source is HDMI 1 and both Digital and Analog Audio are set to “Off”, only video output will be available but no audio. Ideally, when the selected Video input is HDMI 1, it follows that the Digital Audio input is set to HDMI 1 or any of the digital inputs.

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 simplified 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

Scrolling to “A/V Preset” and by	] and	] 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 configurations 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	Setup”	particular	have the following Trigger Out combinations
Trigger			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 “Off” 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) reflects the settings made in the Source Setup (Normal View) menu. All

the Source settings are summarized and displayed in tabulated form in	Source	View).
Navigating through the Source Setup (Table View) via a combination	] and	] keys,

one will have the benefit of directly changing the settings for “Audio”, “Video”, “Preset”, “Trigger” and “Source Name” without going back to the Source Setup (Normal View) menu.

OPERATION

USING THE T 175 –Setup 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 specified time out time. For the “Now Playing” OSD to be shown, there should be a song paused or being played before going to the iPod menu. You can set the “Menu Timeout” between the range 5s to 60s at 5s increments. If you do not want the menu to timeout, select “Off”.

SPEAKER SETUP

After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your listening environment.

The following are the Speaker Setup Menu sections.

IMPORTANT NOTICE

The T 175 is a Tuner Preamplifier only and therefore has no Speakers. The mention of “Speaker(s)” in this manual refers to your external amplifier’s speakers as interfaced with the T 175.

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 configuration 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 offered 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 reflecting 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 effectively 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 configuration. 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.

OPERATION

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 finalized, 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 affect 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 effectively “remove” the walls with room correction, and set the speakers for flat response, you may find 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 find 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 Configuration, 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 configurations as highlighted by an asterisk.

OPERATION

USING THE T 175 –Setup MENU

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 “Off”), but note that physical size may be irrelevant.

•A “Small” speaker is any model, regardless of physical size, that lacks significant 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 “Off” 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 “Off”.

The Speaker Configuration is “global”; that is, it remains in force with all inputs and in all listening modes. However, speaker settings are part of the T 175’s Preset system. Consequently, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require.

Speaker Configuration can be managed and adjusted by pressing a combination of	] and then	]
keys. Set“Front”,“Center”, and“Surround” to“Large,”“Small” or“Off” 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 availability. Set “Subwoofer” to “On” or “Off,” selecting “On” only if you have a subwoofer connected to the T 175’s SUBW1 or SUBW2 output jack.

OPERATION

USING THE T 175 –Setup MENU

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 effects, 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 configurations 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 film, will present the balance of effects, 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 reflective 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 offset” 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.

OPERATION

USING THE T 175 –Setup MENU

To produce the same SPL meter reading (or subjective loudness), use the remote’s [] keys to adjust each speaker.

NOTES

•All speakers must be in their final 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 film sound material, is frequently useful.

•Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always calibrate to exactly the same level offset 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 refinement 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.

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 the mute function.

USING THE T 175 –Setup MENU

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 film’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 fly” 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 off the levels set via Audyssey Auto Calibration.

ZONE SETUP

The Zone feature allows one to simultaneously experience in different 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 configurable 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 amplifier it is fed into.

MODE

Zone 3 and Zone 4 can be configured 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 specific 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.

OPERATION

USING THE T 175 –Setup MENU

TRIGGER SETUP

The T 175 features three	DC Trigger	that can be used to activate a
component or system it is fed into. A Trigger Input is also		to turn on the applicable link it is
associated to. Use a combination	] or [ENTER]	] keys to navigate through the Trigger
Setup menu parameters.

TRIGGER OUT

Triggers are low voltage signals used to turn on/off 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.

AUTO TRIGGER IN

Auto Trigger IN allows external system controllers to toggle the associated section of the T 175 from “Standby” to “On” and vice versa. When the TRIGGER switch at the rear panel is set to ON, a +12V DC input at Trigger IN will power ON the section where Trigger IN is assigned,

Main: From standby mode, the T 175 is powered ON when +12V DC is applied at Trigger IN.

Zone 2, Zone 3, Zone 4: Applicable Zone is turned ON whenever +1 2V DC is present at Trigger IN. All: Main, Zone 2, Zone 3 and Zone 4 as described above will all be activated given a +12V DC input at Trigger IN.

WARNING

See also item “7. +12 V TRIGGER OUT, TRIGGER IN, TRIGGER AUTO/OFF” of REAR PANEL discussion as well as the “TRIGGER OUT” discussion under “SOURCE SETUP (NORMAL)”.

LISTENING MODE SETUP

The T 175 has various listening mode and is mostly configurable. These are provided to reproduce a variety of sound effects depending upon the content of the source to be played. Use a combination ] or [ENTER] ] keys to configure the following settings.

LISTENING MODES

The audio format as detected by the selected Source can be automatically configured 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 configured 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.

None: If “None” is selected, the Dolby Digital format will follow the “Digital” setting set forth at “Other” option under this menu section. See discussion below about “Other”.

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 field. 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 offers a broader dynamic, producing magnificent 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 configured 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 reflected 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 effective dynamic range (subjective range from soft to loud) for playback of Dolby Digital soundtracks. For fully cinematic effect, 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 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 offers 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 different methods of surround signal recording, as follows:

DTS-ES™ 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 effect 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 effects of the right surround, left surround, central and back surround channels add a natural sensation of expansion of the sound field.

OPERATION

USING THE T 175 – AM/FM/DB/iPod

LISTENING TO RADIO

The T 175’s internal AM/FM tuner offers 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.

ASSEMBLING THE LOOP ANTENNA

1Rotate the outer frame of the antenna.

2Insert the bottom edge of the outer frame into the groove on the stand.

3Extend the antenna cord.

SELECTING THE RADIO

Press the [AM/FM/DB] button on the T 175 front panel or the numeric [+10] of the HTRC 1 while at AMP or TUNER device selector page to select the T 175’s radio mode. Each subsequent press of either key will toggle the unit among AM, FM and XM (or DAB) radio.

TUNING STATIONS

After first pressing “TUNER” at the Device Selector page of HTRC 1 to set the remote to control Tuner functions, press [TUNE/] on the HTRC 1 – toggle in to perform slow manual search, press and hold to automatically search.

1Press [TUNE/] on the front panel momentarily to step up or down between AM or FM frequencies.

2Press and hold [TUNE/] for more than 2 seconds to search up or down - the T 175’s tuner will stop at the next sufficiently strong signal it encounters.

3Pressing the [TUNE/] during the search process will stop the search.

SETTING RADIO PRESETS

The T 175 can store a mix of your 40 favorite AM, FM and digital radio for immediate recall.

1To store a radio preset, first tune the desired frequency (see above), then press the front panel [MEMORY] key.

2Press the [PRESET/ ] keys to select a “Preset Free” number to be assigned.

3Then, press the [MEMORY] key once again to save the station to the particular Preset number and displaying “P_ _” (the two blank spaces will correspond to the preset stored number that could be from “01” to the maximum of “40”) on the VFD.

4Press [PRESET/ ] on the front panel to step up or down between presets. Press and hold [PRESET/ ] to “scroll” continuously up or down. The HTRC 1 remote’s [PRESET] keys work similarly.

The T 175’s Radio Presets are distinct from its “global” Presets that can be used to manage listening and setup modes and levels. See “A/V PRESETS” above.

OPERATION

USING THE T 175 – AM/FM/DB/iPod

CHOOSING THE TUNER MODE

The front-panel [TUNER MODE] key is a dual-purpose control. In the normal position, FM Mute FM Stereo icons on the VFD are illuminated, only the stations with a strong signal can be listened to, and the noise between stations is muted.

Pressing the [TUNER MODE] button again (FM Mute FM Stereo icons on the VFD are extinguished) allows distant and potentially noisy stations to be received. Noise is reduced if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently less noise-prone) though at the sacrifice of the stereo effect.

NOTE

One can store the same channel in two preset locations - one with TUNER MODE On and another with TUNER MODE Off.

ABOUT USER NAMES

You can assign an eight character “User Name” to each radio preset, which will show in the front-panel readout whenever that preset is recalled.

ABOUT RDS

The Radio Data System (RDS) permits sending small amounts of digital information using conventional FM radio broadcasts. The T 175 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). Not every FM station incorporates RDS in its broadcast signal. In most areas you will find from one to several RDS-enabled stations, but it is by no means impossible that your favorite stations will not be broadcasting RDS data.

VIEW RDS TEXT

When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS” symbol will illuminate in the T 175’s front-panel readout and the readout’s character section will show its station-name (PS) text: “ROCK101”, for example.

Press the front-panel INFO key to toggle the readout between this and the station’s radio-text (RT) readout, if any, which might scroll songor artistname, or any other text of the station’s choosing.

ABOUT XM RADIO

The T 175 is “XM Ready” which means that with the addition of separately sold XM Mini-Tuner CPC-9000 and XM Mini-Tuner Home Dock, it has everything you need to listen to live XM. Everything else is built right in. Just subscribe to the XM service and your T 175 will be ready to receive XM content.

OPERATION

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-specified 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.

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 first station is tuned in (See “ALPHANUMERIC” section below to understand the order or arrangement of stations).

4The 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		DAB broadcast
providers for coverage information.

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 amplifiers, preamplifiers, 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 different functions, depending on the selected DEVICE SELECTOR key, the HTRC 1 uses color coding to indicate the function of the function keys when different 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 amplifier 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 first 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 first line of the LCD display will show “MACRO.” Within five 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

• You

menus by selecting “Exit” or pressing the MACRO key.

•] cursor keys to select different 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 confirm a value.

•While a setup menu page is being executed, the corresponding first 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.

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 configuration 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 first line of the LCD display. If within five 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 five seconds to display version numbers.

SETUP MENU

Press and hold the SETUP and ENTER keys for five seconds to enter the Setup Menu. You cannot enter the setup menu if the remote is currently displaying “Low Batt.”This feature prevents the setup from becoming 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 off again five 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.

LEARN

This function allows you to learn IR commands from another remote.

Example: Learning “MENU” function from a TV remote control into the MENU button of HTRC 1’s TV device.

Begin by positioning the HTRC 1 “nose-to-nose” with the source remote so that the two devices’ infrared windows are about 2 inches apart.

1 Press [TV] in the DEVICE SELECTOR page.

2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use ] to scroll to “Learn”.

3 Press [ENTER].

OPERATION

USING THE HTRC 1 REMOTE CONTROL

3Press [ENTER].

4Press [MENU] button of HTRC 1 – [MENU] button of the HTRC 1 is where the corresponding [MENU] function key of the TV remote control will be learned.

5Press and hold the corresponding [MENU] button of the TV remote control until “Success” is shown in the display. (Refer also to “MODE” discussion below).

6“Success” will be shown in the display if the [MENU] function key is successfully “learned.” You can now release the [MENU] button of the TV remote control.

7Wait until “Success” is extinguished from the display to complete the process.

NOTE

“Failed” will be shown in the lower line display if the “learning” of the desired function key is unsuccessful. Repeat Step 3 – 7 again until “learning” of the desired key is successful.

MODE

There are three modes on how a function key can be learned. Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons. Use [] to scroll to “Learn.”Press [ENTER] and then [] to scroll to “Mode”. The following are the three modes:

Normal: This is the regular learning mode. A function key is learned until “Success” is shown in the display. The example above is at“Normal” learn mode.

2 Pass: Some remote controls use an IR (infrared) “toggle bit”. This means that if you press the same key twice in a row, the IR signal toggles between two different variations of the same command.

At “2 Pass” mode, step 5 and onwards of the above example would be as follows (the same Steps 1 – 4 of the above example applies)

5Press and hold the corresponding [MENU] button of the TV remote control.

6Release [MENU] button.

7“Pass 2” means that you have to press [MENU] button again. Press until “Success” is shown in the display.

8“Success” will be shown in the display if the [MENU] function key is successfully “learned.”You can now release the [MENU] button of the TV remote control.

9Wait until “Success” is extinguished from the display to complete the process.

Narrow: Some remote controls use very narrow pulses of IR. If you cannot get your remote to work using the normal or 2 Pass modes, you may want to try this mode. The same example above for “Normal” mode applies to “Narrow” mode.

PUNCH-THROUGH (Pun Thr)

The HTRC 1’s “Punch through” function allows you to retain a function key from one DEVICE SELECTOR “page” to another.

Example: Punch-through “SURR MODE” key to the “DVD” page. 1 Press [DVD] in the DEVICE SELECTOR page.

2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons ] to scroll to “Pun Thr”.

2 Press and hold [TUNER (10+/SETUP)] and [ENTER] buttons ] to scroll to “Rename”.

3Press [ENTER].

4Press [1] button.

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.

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):
