THANK YOU FOR CHOOSING NAD

The L 54 DVD Receiver is a technologically advanced and highly capable product-yet we have invested great effort in making it simple and easy to use. The L 54 delivers a range of genuinely useful options for stereo listening using powerful digital signal processing and superbly accurate digital-audio circuitry. However, we have also been careful to ensure that the L 54 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-theatre components. As with all our products, NAD's "Music First" design philosophy guided the L 54's design, such that it can confidently promise you both state-of-the-art surround home-theatre 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 L 54, and get the most from this powerful and flexible home-theatre component.

One more thing: We urge you to register your L 54 ownership on the NAD Worldwide Web site:

http://NADelectronics.com/warranty

For warranty information contact your local distributor.

UNPACKING AND SETUP

WHAT'S IN THE BOX

Packed with your L 54 you will find:

An AM loop antenna
An FM ribbon-wire antenna with balun
The HTR 4 remote control with 4 (four) AAA batteries
This owner's manual

SAVE THE PACKAGING

Please save the box and all of the packaging in which your L 54 arrived. Should you move or otherwise need to transport your receiver, this is by far the safest container in which to do so. We've seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!

CHOOSING A LOCATION

Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within 25 feet/8 meters, between the L 54's front panel and your primary listening/viewing position. This will ensure reliable infrared remote control communications. The L 54 generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the L 54 atop other components, but the reverse usually should be avoided.

Nonetheless, it is generally preferable that the L 54 stands alone. It is especially important that sufficient ventilation be provided. If you are contemplating locating the L 54 within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.

QUICK START

In case you simply cannot wait to experience the performance of your new NAD L 54 DVD Receiver, we provide the following "Quick Start" instructions to get you underway. Before the steps below, connect your L 54 to a TV/monitor.

Please make all the connections to your L 54 with the unit unplugged. It is also advisable to power-down or unplug all associated components while making or breaking any signal or AC power connections.

PLAY A CD OR DVD MOVIE

• Connect the L 54's composite Video or S-Video "MONITOR OUT"jack to your TV/monitor's corresponding input.
• Connect your left and right front speakers to the L 54's "L" and "R" outputs. Make sure to connect red to red ("+") and black to black ("-") with care to avoid stray wires or strands crossing between terminals. If your system includes a powered subwoofer, connect the L 54's "SUBWOOFER PRE-OUT" jack to its line input.
• Plug the AC mains plug into the AC outlet; the LED on the front panel will be illuminated blue indicating the L 54 is in standby mode ready to accept commands from either the front panel power switch or the HTR 4 remote.
• To start playback of the DVD player; press "DVD" at the HTR 4 remote's Device Selector section and then "OPEN/CLOSE" button.
• Insert the media and press▶[PLAY] button to start playback. You should hear stereo sound, and see an image on the TV/monitor. (If one or the other fails to appear, you may need to use either the L 54's on-screen menu system to check assignment of audio and video inputs (See section on "Video Out" under the heading "Operation.")

Enjoy the movie or music, but be sure to set aside time to read this manual thoroughly, and to set up, calibrate, and configure your L 54 carefully and completely.

ABOUT THE L 54

Though the L 54 is among the most technically sophisticated integrated Stereo DVD receivers, we worked hard to make it one of the most musically transparent home-theatre components available as well - this is what we mean by NAD's "Music First" design philosophy. Here are just a few examples:

• High-performance components used throughout the receiver's analog audio circuits maximize quality from all sources.
• The L 54 incorporates a high quality DVD player with exceptional playability. The player has support for DVD video, VCD, SVCD with playback control (PBC), DivX, CD audio such as CD-RW as well as recorded MP3, copyright-protected WMA and JPEG files.
• Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.

EASE OF USE

Despite the effort NAD has invested in the L 54's sonic performance, we expended no less in making it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and the HTR 4 universal remote control is equally understandable, as are the L 54's own front panel and on-screen displays (OSD).

ABOUT THE HTR 4 SYSTEM REMOTE CONTROL

Packed with your L 54 is the NAD HTR 4 remote control, a full-system remote especially designed for easy use and understanding. Be sure to read the section "Using the HTR 4 Remote Control" to familiarize yourself with the remote's layout and operations before proceeding to setup your L 54.

Chances are you will want to use your HTR 4 as your primary way to command your entire A/V system. The HTR 4 can be employed to operate additional NAD or other-brand components such as a second DVD/CD player, television, satellite/HDTV tuner, VCR, or virtually anything else that operates via standard infrared remote control.

18 PHONES: Accepts stereo headphone using a standard 1/4-inch stereophone plug (use a suitable adaptor for headphones equipped with a smaller plug). Plugging in headphones automatically mutes output from the speakers (but not from the AUDIO OUT jacks of the VCR at SRS OFF).

REAR PANEL

ATTENTION!

Please make all the connections to your L 54 with the unit unplugged. It is also advisable to power down or unplug all associated components while making or breaking any signal or AC power connections.

1 SPEAKERS: Connect the left and right terminals to the corresponding loudspeakers. Each output's "+" (red) terminal and "-" (black) terminal must be connected to the corresponding "+" and "-" terminals of the loudspeaker. Use extra care to ensure that no stray wires or strands cross between posts or terminals at either end.

NOTES

• Use stranded wire of at least 16-gauge (AWG); specialized speaker cable may be valuable (consult your NAD audio specialist). Connections to the L 54 can be made with banana-type plugs, or using bare wire, or pins, by loosening the terminal's plastic nut, making a clean, neat connection, and re-tightening carefully (use the transverse hole through the post for bare-wire or pin connections). To minimize the danger of short-circuits, ensure that only 1/2-inch of exposed wire or pin is employed in connecting.
• This unit is designed to produce optimum sound quality when connected to speakers with impedances within the receiver's operating range. Please check that speakers are rated to be 8 ohms minimum per speaker.

2 FM ANTENNA : The supplied wire "dipole" FM antenna will connect to the FM connector using the supplied "balun" adaptor. 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. Experiment with placement and orientation to yield the clearest sound and lowest background noise.

In areas of difficult FM reception, an external FM antenna can yield dramatic gains in quality; consult your NAD audio specialist or a professional antenna installer.

3 AM ANTENNA: The AM loop antenna supplied with the L 54 (or a suitable replacement) is required for AM reception. Open the clip terminal lever; insert the wire making sure to match the color-coded (white and black) ends of the wire to that of the terminal and close the lever ensuring that the lever locks the wire in place. Testing different positions for the antenna may improve reception; vertical orientation will usually produce the best results. Antenna proximity to large metal objects (appliances, radiators) may impair reception, as will attempts to lengthen the wire to the loop.

NOTE

An external AM antenna can improve long distance reception substantially; consult your NAD audio specialist or a professional antenna installer. Do not connect anything other than a loop antenna to the AM ANTENNA terminal.

4 CABLE/SAT & VCR: These comprise the L 54's principal inputs. Connect S-Video, composite video, and analog stereo audio from source components such as HDTV/satellite tuners. VCR may be used with recording components such as videocassette or DVD-recorders. Connect the L 54's VCR Audio/Video OUT to these components' record-input. (Make sure that SRS is set to OFF). Note that VCR may freely be used for play-only components, in which case their OUT jacks would remain unconnected.
5 PRE-OUT SUBWOOFER: Connect this output to a powered ("active") subwoofer (or to a power amplifier channel driving a passive system).
6 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 L 54 from a remote location. Ask your dealer or custom installer for further details.

7 DIGITAL INPUTS, OPTICAL & COAXIAL: Connect to the coaxial/ optical S/PDIF-format digital output of sources such as HDTV, satellite tuners or other components. Connect OPTICAL/COAXIAL DIGITAL INPUT to an S/PDIF-format digital output. We recommend your source material be set to PCM 2-channel format for these digital inputs.
8 DIGITAL OUTPUT, OPTICAL: Connect the OPTICAL DIGITAL OUTPUT port to the corresponding S/PDIF digital input of a recording component such as a CD recorder, DAT deck or computer soundcard.
9 COMPONENTVIDEO OUT: Connect the L 54's "COMPONENTVIDEO OUT" to the component video input of a compatible video monitor/TV. Be sure to observe consistency in connecting the appropriate Y, Cb/Pb, Cr/Pr jacks to the corresponding sources/inputs. Do not rely purely on the color coding of the jacks, which may not always be consistent among brands. The routing of the component video output is fixed.

The L 54's component-video output is a fully wide-band output, compatible with all HDTV formats. On-screen display menu is also shown at component video output.

NOTES

• Make sure to set 'VIDEO OUT' to 'COMPONENT' at the SETUP menu for video to be available at Component Video OUT. See also section 'VIDEO OUT' at "Setup Menu" discussion.
• "COMPONENT VIDEO OUT" jack will only display the internal DVD video signals.

10 AC POWER CORD: Connect AC power cord to the voltage according to the model, 120V for US and 230V for Euro models.
The clock resets to "00:00" when the AC power cord is unplugged and then plug-in again to the power source.
11 SWITCHED AC OUTLET: This convenience jack can supply switched power to another component or accessory. It is powered on and off by the front panel POWER button (or the HTR 4's ON and OFF buttons). The total draw of all devices connected to this jack must not exceed 100 watts.
12 SCART/RGB OUT (Euro model/PAL only): Connect the L 54's "SCART/RGB OUT" to the SCART/RGB video input of a compatible video monitor/TV. Be sure to observe the correct orientation of the SCART/ RGB plug. Make sure also to set 'VIDEO OUT' to 'RGB' at the SETUP menu for stable video availability at SCART/RGB OUT.
13 MONITOR OUT: Connect to video input of the monitor/television, using quality 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.

Make sure also to set 'VIDEO OUT' to 'S-Video' at the SETUP menu for video to be available at 'S-Video' Monitor OUT.

GETTING STARTED

Before you make the first connection to your L 54, you should have the arrangement of your listening room/home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital questions of loudspeaker placement and listening/viewing positions is beyond our scope here. Suffice it to say that these two questions will influence your system's ultimate performance every bit as powerfully as your selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you and to recommend reference materials.

DEALING WITH HUM AND NOISE

Hum and noise sometimes may prove a challenge in audio systems. Note these considerations to help prevent hum and noise problems:

• Power all your system's audio component from AC outlets originating from the same circuit of your house wiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on the same circuit. It may be useful to power video displays (and computers!) from outlets on another circuit, especially if that circuit is supplied from the other "leg" of the house wiring.
• Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. It is best if they cross at right angles if they must be in close proximity.
• Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure.
• A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low-resistance contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging since the gold (or copper) contact plating of typical cable connectors, even very high-quality ones, is very thin and easily worn.

Track down hum/noise problems one component at a time, working backwards from the L 54. That is

a Connect the speakers to the L 54 only, and check for hum.
b Then connect one component only (a CD player, for example) alone, with no other components connected and check for hum.
c Connect additional components, one at a time, to the L 54 and check for hum.

At each stage, if hum/noise appears, examine the audio cabling and AC-power routing of the new component. In some cases, moving the new component's AC cord to a different outlet, or installing a ground-lift (3-to-2-prong adapter) on its power cord, will eliminate the hum.

FACTORY DEFAULT SETTINGS

Sometimes power spikes and drop-outs may from time to time cause some inadvertent functionality. The procedure below will set the L 54 to factory default settings

1 Place the L 54 into AM mode.
2 Press quickly the three front panel buttons; "PLAY/PAUSE", "STOP/Open" then "DISPLAY", holding the "DISPLAY" button for more than 7 seconds. The L 54 will switch itself off, then back on to DVD mode.

Please note that setting the L 54 to factory default will delete all AM and FM presets.

ABOUT THE ON-SCREEN DISPLAY (OSD)

The L 54 employs a self-explanatory on-screen display "menu" for the internal DVD player. This "menu" will appear on the connected video monitor/TV and is required during the setup process (useful in day-to-day operation), so be sure to connect the monitor/TV before proceeding with setup.

DISPLAYING THE L 54 DVD OSD

While in DVD mode, press the L 54's "SETUP/MEMORY" button momentarily for the DVD's Setup Menu OSD to appear. With the use of the HTR 4's navigation buttons, you may select various menus. If the Setup Menu does not appear, check your applicable "MONITOR OUT" connections either "COMPOSITE" or "S-VIDEO" outputs.

The L 54'S Setup Menu OSD will appear on the Component Video OUT (NTSC/PAL), SCART/RGB (PAL) output, Monitor OUT (Video/S-Video) and on the VCR record outputs.

AUDIO MODE

The AUDIO MODE feature of the L 54 allows one to adjust or configure SRS, BASS, TREBLE, LEFT channel, RIGHT channel and DRC. Press AUDIO MODE button on the front panel or HTR 4 (make sure you are at AMP device) and then use the VOLUME knob or the HTR 4's volume / keys to adjust or configure these features.

SRS TRUSURROUND

SRS Labs developed TruSurround®, a patented technology that accepts any multichannel source such as Dolby Digital, Dolby Surround or DTS, including MPEG 1 and 2 and transforms it into a compelling surround sound experience over just two speakers or headphones.

TruSurround is suited for any environment where multichannel content is experienced without the benefit of having surround sound speakers installed. With TruSurround, incoming multichannel audio is processed into two channels and delivered over stereo speakers, giving the listener a completely immersive experience and the sensory perception that additional "phantom" speakers surround them.

To activate SRS TruSurround, press "AUDIO MODE" at the front panel or HTR 4 remote. Select SRS mode. Toggle the SRS to ON or OFF using the L 54's volume knob or the HTR 4 volume / keys.

NOTE

SRS TruSurround is designed to be used with surround encoded soundtracks, such as those found on movies and music video DVDs. Results with stereo music soundtracks typically found on CDs can be variable and we generally do not recommend SRS for enhancing these programs. Furthermore, SRS decoding is only available on digital sources and cannot be selected for analog sources such as FM radio and VCR inputs.

LEFT AND RIGHT (BALANCE ADJUST) SETUP

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.

After selecting "AUDIO MODE", toggle from "LEFT" and "RIGHT" level adjustment and fine tune the level of each channel with the volume knob or remote's volume / keys.

ADJUSTING THE TONE CONTROLS

The L 54 is fitted with BASS and TREBLE tone controls to adjust the tonal balance of your system. Maximum and minimum values for both tone controls are - / + 10 dB. Bass/treble settings affect only the front left/right channels, not the subwoofer.

DYNAMIC RANGE CONTROL (DRC)

You can select the effective dynamic range (subjective range from soft to loud) for playback of Dolby 2.0 soundtracks. Settings of 25% , 50% and 75% progressively reduce dynamic range, making soft sounds comparatively louder while limiting the peak loudness of loud ones.

The 100% setting is best for late-night sessions or other times when you wish to retain maximum dialog intelligibility while minimizing overall volume levels. To maintain full dynamic range, set DRC to OFF.

NOTE

To access DRC feature, always set SRS first to OFF.

INPUT SELECT

Aside from the L 54's internal DVD and tuner section, the L 54 is also equipped with 3 inputs - Audio/ Video inputs labeled "CAB/SAT", "VCR" and "VIDEO 4 (VIDEO 4 on the front panel). The input becomes active whenever it is selected.

From the front panel, press the "INPUT SELECT" button to toggle from DVD, CABLE/SAT, VCR, VIDEO 4, AM, FM and then back to DVD. If the L 54 is in standby mode, the "STOP/OPEN" button will automatically select DVD mode.

Incoming digital and audio signals present at either digital or analog audio are assigned to their fixed inputs - CAB/SAT and VCR. Assign either coaxial or analog audio to CABLE/SAT input by toggling the L 54's 'DISPLAY' button on the front panel. The selected audio input will be displayed on the VFD after releasing the 'DISPLAY' button. The same procedure is applicable when assigning optical or analog audio to the VCR input.

The assigned audio input will always be recalled whenever that input is selected via the front panel INPUT SELECT or the HTR 4 remote's input-select buttons.

It is not necessary to connect at the same time both analog audio and digital audio input for every video input you employ. It is preferable to make only digital audio link to the L 54 for audio playback. This avoids possible confusion and ensures that the L 54's high performance digital audio circuitry will always be employed.

ADJUSTING THE VOLUME

In addition to the Volume knob, use the HTR 4's VOL / keys to adjust the volume of the L 54 raising or lowering the channels altogether. With HTR 4's VOL / keys, a momentary keypress will change the volume by 1 dB increments. If you hold down VOL / keys, the volume level 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 volume setting. A setting of -20 may sound "as loud" from one CD or DVD as -10 does from another.

The L 54 will power-up from Standby mode at whatever master volume setting was last used; however, if the prior setting is greater than -10dB , the L 54 will power up at -10dB . This prevents inadvertently beginning a session at excessive volume.

MUTING THE SOUND

Use the HTR 4's 'Mute' key to silence all channels completely. Muting is always available regardless of the source or listening mode selections. Note that adjusting the volume upward via the HTR 4 or the front panel knob automatically releases the mute function.

ADJUSTING THE SUBWOOFER LEVEL TRIM "ON THE FLY"

You can make changes to the relative level of subwoofer output. This may prove useful in a number of circumstances; for example to reduce excessive deep bass (or enhance deep bass) by lowering (raising) the subwoofer level.

Use the HTR 4's 'SUB' keys for direct-access level adjustment of these channels over a range of ± 12 dB.

You may operate the L 54 DVD Receiver from its front panel or via the HTR 4 remote control. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure also to read the section, "Front Panel".

REGION MANAGEMENT INFORMATION

The L 54's internal DVD Player is designed and manufactured to respond to the Region Management Information that is recorded on a DVD disc. If the Region number described on the DVD disc does not correspond to the Region number shown on the back of the L 54, the internal DVD player cannot play that disc.

ABOUT DVD/SVCD/VCD/CD

The L 54's internal DVD/SVCD/VCD/CD player will play DVD, SVCD with or without PBC (Play Back Control), VCD, DivX and CDs including recorded MP3, copyright-protected WMA and JPEG files. To turn on or off PBC, toggle the "MENU" button on the HTR 4.

NOTE

You cannot playback discs other than those listed above such as Video, CD-CD-ROM, CD-Extra, CD-G, photo-CD, and CD-i data discs. To do so may render the L 54 permanently inoperable.

DISC LOADING AND PLAYBACK

You can open the disc tray by pressing 'STOP/OPEN' button even if the L 54 is in standby mode. The power indicator will turn from blue to dark. Place a disc on the disc tray with the playback side down.

There are two different disc sizes. Place the disc in the correct guide on the disc tray. If the disc is out of the guide, it may damage the disc and cause the L 54 to malfunction. 'NO DISC' appears on both the L 54's display and the TV/monitor screen, if the disc is placed upside down (and it is a single sided disc).

The following are important tips when loading a disc

• Do not push the disc tray while it is moving. Doing so may cause the L 54 to malfunction
• Do not push up the disc tray or put any objects other than discs on the disc tray. Doing so may cause the L 54 to malfunction.
• Keep your fingers well clear of the disc tray as it is closing. Be especially careful with children's fingers around the closing disc tray, as there is a risk of personal injury.

Press "PLAY/PAUSE", the disc tray is automatically closed and playback begins. Press the HTR 4's navigation buttons and then press "ENTER" or press the numeric button(s) to select the desired track (CD). Play of the selected item now begins (Depending on the DVD disc or other disc media, some operations may be different or restricted. Refer to the jacket or case of the disc you are playing).

Press the HTR 4's "STOP" key during playback to display an audio CD's total number of tracks and total playback time in the VFD.

If you insert a SVCD videodisc, the PBC symbol (Play Back Control) will appear in the L 54's display and OSD. The "MENU" button on the HTR 4 will toggle on and off PBC.

After playing back all of the chapters in the title, L 54's DVD player automatically stops and returns to the menu screen.

NOTE

Do not move the L 54 during playback. Doing so may damage the disc and the L 54.

ROTATE PICTURE

Press / / keys during the showing of a picture to rotate the picture '90 deg,"180 deg,270 deg' and back to 'Original'.

The L 54'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

1 Rotate the outer frame of the antenna.
2 Insert the bottom edge of the outer frame into the groove on the stand.
3 Extend the antenna cord.

SELECTING THE RADIO

To select the L 54's tuner mode, press "INPUT SELECT" button on the front panel repeatedly until AM/ FM mode or the HTR 4's numeric +10' while at AMP or TUNER device selector page.

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

Press and hold TUNE / for more than 2 seconds to search up or down - the L 54's tuner will stop at the next sufficiently strong signal it encounters. Pressing the TUNE / during the search process will stop the search.

SETTING RADIO PRESET

The L 54 can store as many as 60 (30 FM and 30 AM stations) of your favorite radio stations for immediate recall. To store a radio preset, first tune the desired frequency (see above), then press the front panel "SETUP/MEMORY" button. The VFD will show a blinking "PROG" icon and a vacant Preset number.

Press "SETUP MEMORY" button again to store the desired frequency on the Preset number shown or use the keys to select another available Preset number. Then, press "SETUP/MEMORY" key button again.

The Radio Presets must be stored from the front panel. This setup function is not accessible from the HTR 4 remote control.

Use the PRESET / keys on the front panel to step up or down between presets. Press and hold PRESET / to "scroll" continuously up or down. The HTR 4 remote's 'PRESET' keys work similarly. Empty presets will be skipped during preset tuning.

DELETING A STORED PRESET

You can empty a preset by deleting the stored information.

1 Select the preset number to be emptied.
2 First press the DISPLAY button and hold it in. While holding in the DISPLAY button press the SETUP/ MEMORY button for about one half second, then release the SETUP/MEMORY button.
3 The preset will then be deleted and "DELETED" scrolls on the display.
4 To clear all the Presets at the same time, repeat step 2 again but this time do not release the SETUP/MEMORY button. Hold down both buttons until the current Preset number shown in the VFD is extinguished. All Presets are now deleted.

CHOOSING FM MUTE/MODE

The front-panel 'FM MUTE/MODE' key is a dual-purpose control. In the normal position, "ST" and "MUTE" icons on the VFD are lit; only the stations with a strong signal can be listened to, and the noise between stations is muted.

Pressing the "FM MUTE/MODE" button again ("ST" and "MUTE" 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.

The Radio Data System (RDS) permits compatible tuners to display text determined by the broadcaster. The L 54 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). However, 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.

VIEWING RDS TEXT

When an RDS-enabled FM broadcast is tuned, after a brief delay the "RDS" symbol will light in the L 54's front panel readout and the readout's character section will show its station-name (PS) text: "ROCK101,"for example.

Press the front panel DISPLAY key to toggle the readout between this and the station's radio-text (RT) readout, if any, which might scroll song- or artist-name or any other text of the station's choosing.

The NAD HTR 4 is ready to operate the L 54 right out of the box, but it is really eight remotes in one. Each of the 8 Device Selector keys at the top of the handset can call up a new "page" of remote control codes to be transmitted by the remaining 44 keys. You may "teach" codes from any infrared-remote controlled component, regardless of brand, to any or all of these.

Obviously, the most logical system is that you teach the codes from your DVD player to the [DVD] Device Selector "page," your television's codes to the [TV] "page," and so on, but there is no required scheme: You may load any commands to any key on any page (see "Learning Codes From Other Remotes," below).

The HTR 4 is already preprogrammed with a full complement of commands for the L 54 on its [AMP] Device Selector page, and as well as with library commands to operate most NAD-brand DVD, CD or TAPE components on the corresponding Device Selector "pages." These default commands are permanent: Even if you teach the HTR 4 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 (see "Delete Mode", below).

Note: For use with the L 54, it should not be necessary to re-program any keys on the HTR 4 [AMP] page. However, in order for the HTR 4 to control your specific NAD-brand components you may need to load one or more different code-libraries (see "Loading Code Libraries," below).

CONTROLLING THE L 54

The HTR 4 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [DVD], [TV], and so on—set the handset's remaining keys to a "page" of commands to control a particular component. A Device Select key determines only what component the HTR 4 will command; it does not perform any function on the L 54. All of the remaining keys are function keys that can "learn" control codes from virtually any infrared remote controller, allowing you to teach the codes of your equipment, regardless of brand, to the HTR 4.

However, the HTR 4 is already preprogrammed to operate the L 54. All of the function keys on the [AMP] Device Selector "page" perform L 54 functions. (The HTR 4 can also command many other NAD components, from its [DVD], [CD], [TUNER], and [TAPE] pages.)

It is important to note that certain HTR 4 keys perform different functions depending on the selected Device Selector "page." The color of the Device Selector key-labeling corresponds to the labeling of the function keys. Most centrally, the orange [AMP] Device Selector "page" corresponds to the orange input-select labeling above the numeric keys: When the HTR 4's [AMP] Device Selector page is active, these keys select the Receiver inputs. Similarly, the purple [DVD] Device Selector "page" corresponds to several purple labels, the green [TV] page to green labels, and so on.

LEARNING CODES FROM OTHER REMOTES

Begin by positioning the HTR 4 "nose-to-nose" with the source remote so the two devices' infrared windows are about 2 inches apart.

• Enter Learning Mode: On the HTR 4, simultaneously press-and-hold for 3 seconds both a Device Selector key and the key until the Learn LED at the center of the HTR 4 turns steady green.
  Press the HTR 4's function key you wish to teach a command; the Learn LED will turn amber.
• Press-and-hold the function key on the source remote: The HTR 4's Learn LED will flicker amber for a second or two, then turn solid green. The command is learned.
  Press the HTR 4's Device Selector key again to exit the learning mode.

If the Learn LED does not flicker amber you may need to vary the distance between the remotes. If the Learn LED turns red rather than green, that particular command of that source remote command could not be learned.

CANCEL OPERATION

You can cancel configuring a key, by pressing the active Device Selector key before the learn process is complete; the Learn LED will turn red.

Example: Learning "DVD Pause"

Position the HTR 4 and your DVD player's remote as described above.

• On the HTR 4, simultaneously press-and-hold [DVD] and ; the Learn LED turns steady green.
  Press the HTR 4's key; the Learn LED turns amber.
• Press-and-hold the DVD player's remote's pause key; the HTR 4's Learn LED flickers amber and then turns solid green. The command is learned.
  Press [DVD] again to exit the learning mode.

PUNCH-THROUGH

The HTR 4's "punch-through" function allows you to retain a function key from one Device Select "page" to another, so that, for example, the AMP [AUDIO MODE] function might still control the L 54 when the DVD Device Selector page is active.

NOTE

The HTR 4's [VOL] keys are pre-programmed as "punched-through" for all Device Select pages: [VOL] will operate the L 54's volume regardless of the currently selected device. The [SUB] level control is similarly pre-programmed as punched-through.

To set a punch through, after entering the Learning Mode, and pressing the desired key to be punched through, simply press the device key twice of the device to punch through to. The status LED will turn green; press the Device Selector key again to exit Learning Mode.

Example: Punch-through AMP [AUDIO MODE] key to the DVD "page"

• On the HTR 4, simultaneously press-and-hold [DVD] and ; the Learn LED turns steady green.
  Press [AUDIO MODE]; the Learn LED turns amber.
  Press [AMP] twice; the Learn LED turns green.
  Press [DVD] again to exit the learning mode.

COPY COMMAND FROM ANOTHER BUTTON

You may copy a command from any HTR 4 key to any other key. To copy a key function, after entering the Learning Mode, and pressing the desired key to be copied to, simply press the device key from which you wish to copy, having first pressed its Device Selector key if it resides on another "page." The status LED will turn green; press the Device Selector key again to exit Learning Mode.

Example: Copy the Pause command from the CD page to the AMP key:

• On the HTR 4, simultaneously press-and-hold [AMP] and ; the Learn LED turns steady green.
  Press III(pause); the Learn LED turns amber.
  Press [CD]; press II(pause); the Learn LED turns green.
  Press [AMP] again to exit the learning mode.

NOTE

The copy and punch-through functions are similar. However, if you copy a command and then subsequently delete, or over-write the original (source-key) 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.

MACRO COMMANDS

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 HTR 4 can store one macro on each of its function keys (these exclude the Device Selector keys).

NOTE

Macros are independent of the currently selected device.

RECORDING MACROS

To record a macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR 4 function key to which you wish to assign the macro, until the status LED turns green. The macro button will also light up.

Press the sequence of function keys to be recorded into the macro, being sure to first press the requisite Device Selector key for each function (you may switch devices while recording the macro as many times as necessary), allowing you to create macro containing commands from more than one Device Selector "page."

When you have finished entering the desired command sequence, press [MACRO] again to store the macro; the Learn LED and [MACRO] key illumination will turn off.

NOTE

Each macro can store a maximum of 64 command steps. If you exceed this number, the macro will be stored automatically after the 64th command is added.

Example: Record a Macro to the [0] key to Turn on the L 54, Select the DVD Input, and Commence Playback:

• On the HTR 4, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns steady green.
• Press [AMP]; press [ON]; press [1] (red "DVD"); press [DVD]; press ] (Play) - the Learn LED blinks as each step is added.
  Press [MACRO] again to exit the macro-record mode.

To clear a macro, perform the above steps without entering any functions.

EXECUTING MACROS

To execute a macro, press and release [MACRO]; its key illumination lights for 5 seconds. While it remains lit, press an HTR 4 key to which a macro has previously been stored.

The corresponding macro will run; as each step executes, its "parent" Device Selector's key flashes lights briefly; when execution is finished, the [MACRO] key illumination goes out. Pressing any other HTR 4 key while a macro is executing will abort the macro. Remember that you must hold the HTR 4 so that its infrared emitter can activate the target components.

NOTE

When a macro executes, a 1 second delay is automatically inserted between its commands. If you need more than a 1 second delay between particular commands — for example, to permit a component to power up completely — you can record "empty" steps into the macro by changing Device Selector "pages" without entering actual command functions.

BUTTON ILLUMINATION TIMEOUT

The HTR 4's key-illumination can be set to remain lit for 0-9 seconds. The default value is 2 seconds. To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 4's [DISP] and the [0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash twice to confirm the new setting. When set to zero, the illumination will not turn on at all.

NOTE

Key illumination is the biggest drain on the HTR 4's batteries. A short key-illumination timeout will extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further.

FACTORY RESET

The HTR 4 can be reset to its factory state, deleting all learned commands, copied and punched through keys, macros, and other setup information, reverting all keys to their pre-programmed library commands.

To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 4's [ON] and [RTN] keys; the Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the Learn LED will turn red, indicating the remote has been reset.

NOTE

You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not reset; should this occur, repeat the full procedure.

DELETE MODE

The HTR 4 can store learned, copied, and "default library" commands on any single key (The default library commands are the pre-programmed NAD codes, such as the native L 54 commands on the [AMP]"page").

You can delete commands by layers back "down" to the default library command on any key, removing learned commands, punched-through functions, and copied keys.

NOTE

The default library commands cannot be deleted, so you need not worry that using Delete Mode might cause irreparable changes.

To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired key's Device Selector key and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wish to delete; the Learn LED flashes; the number of times indicates which type of function has become active - see the table below. Press the active Device Selector key again to exit Delete Mode.

NOTE

You may delete multiple function-key commands on the same Device Selector "page," but to delete from more than one Device Selector page you must exit Delete Mode and then re-enter it on the required page.

Flashes	Command Type
1	Default Library Command
2	Copied Library Command
3	Learned Command

LOADING CODE LIBRARIES

The HTR 4 can store a different library of default NAD codes for each of its Device Selector "pages." If the original default library does not control your NAD CD player, tape deck, DVD player, or other component, follow the procedure below to change the code-library.

Begin by ensuring that the component you wish the HTR 4 to control is plugged in and powered-up ("on," not merely in standby). To enter the HTR 4's Library Mode, simultaneously press-and-hold for 3 seconds both the desired Device Selector key and the [PROGRAM] key, until the Learn LED turns green.

While keeping the HTR 4 pointed toward the component, enter the first appropriate three-digit code-library number from the table below. If the component turns off, press [ENTER] to accept that code-library number and exit the Library Mode. If the component does not turn off, enter the next three-digit code-library number from the table.

When you enter the correct number the component will turn off; press [ENTER] to accept that code library number and exit the Library Mode.

NAD-brand component	HTR 4 code-library numbers
CD Player (new)	200
CD Player (old)	201
Tape Deck B	400
Tape Deck A	401
T562	600
T550, L55	601
T512, T531, T532	602
T571, T572	602
L56	604
T513, T533	605

SEARCH MODE

If none of the codes from the table, when entered, turns on the component, and if you are quite sure you have followed the above procedure completely and carefully, you may want to try the "search" method as follows:

Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired Device Selector key and the [PROGRAM] button until the Learn LED turns green. Now press-and-hold the HTR 4's [▲] or [▼]) key; the remote will step through all the available codes at a rate of approximately 1 per second.

When the component turns off, immediately release the cursor key; press [ENTER] to accept that code-library and exit the Library Mode. Try a few commands; should you prove to have stepped past the needed code-library, re-enter the Library Mode and use the cursor key to step back to it.

NOTE

It is possible that search mode will find code-libraries that operate, at least partially, some other brand (non-NAD) components. You may certainly exploit such capabilities as you find them. However, since we can only ensure the completeness or accuracy of NAD code-libraries, we cannot support the HTR 4's operation with other-brand components.

USING THE HTR 4 REMOTE CONTROL

CHECKING CODE-LIBRARY NUMBER

You can check the current code-library on any Device Selector key as follows. Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired component's Device Selector key and the [PROGRAM] key until the Learn LED turns green. Press the [DISP] key; the HTR 4 indicates the current code-library by flashing its [TAPE], [VCR], and [MACRO] keys.

For example, to indicate code-library #501, the HTR 4 will flash [TAPE] 5 times, pause, and then flash [MACRO] once. You might wish to make a note of your components' code-library numbers.
