THANK YOU FOR CHOOSING NAD

The L 54 DVD Receiveris 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 spatilly accurate as possible, incorporating much of what weve leamed from a quarter-centurys experience designing audio and home-theatre components. As with all our products, NAD's "Music First” design philosophy guided the L 54% design, such that it can confidentiy promise you both state-of-the-art surround home-theatre and audiophile-quality music listening for years to come

REFERENCE TROUBLESHOOTING . SPECIFICATIONS.… NOTES ........................4444444.ccccsssssssssssssssssss 31 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.

Packed with your L 54 you will find: + An AM loop antenna + An FMribbon-wire antenna with balun + The HTR 4 remote control with 4 (four) AAA batteries +__ This owners manual

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.Weve seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!

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 545 front panel and your primary listening/iewing 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. is perfectiy 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. is especially important that sufficient ventilation be provided. If you are contemplating locating the L 54 within a cabinet or other furiture, 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 TW/monitor. Please make all the connections to your L 54 with the unit unplugged.Itis also advisable to power- down or unplug all associated components while making or breaking any signal or AC power connections.

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 terminals 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 ofshort-circuits, ensure that only 1/2-inch ofexposed wire or pin is employed in connecting. + Thisunit is designed to produce optimum sound quality when connected to speakers with impedances within the receivers operating range. Please check that speakers are rated to be 8 ohms minimum per speaker. 2 FMANTENNA : 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 ofthe 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 à professional antenna installer.

3 AMANTENNA : The AM loop antenne supplied with the L 54 (or à 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 ofthe wire to that ofthe 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 545 principal inputs.

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 furiture mapped out, at least initilly. Unfortunately, discussion ofthe 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 systems 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: + Powerall your systems 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. may be useful to power video displays (and computers! from outlets on another circuit, especially ifthat circuit is supplied from the other‘leg'ofthe house wiring. + Do not bundie analog audio cables with AC power cables, or with coaxial digital-audio cables. Itis best ifthey cross at right angles ifthey must be in close proximity. + Employhigh-qualiy, wel-shielded audio cable throughout, and ensure that all connections are secure. + Apencikeraser 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 € Connect additional components, one at a time, to the L 54 and check for hum: At each stage, ifhum/noise appears, examine the audio cabling and AC-power routing of the new companent. In some cases, moving the new components AC cord to a different outlet, or installing à groundift (3-to-2-prong adapter) on its power cord, will eliminate the hum.

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' volume A/Y 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 volume knob or the HTR4 volume A/Y 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 notrecommend 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 systems loudspeakers ensures that surround-sound recordings, whether music or film, will present the balance of effects, music, and dialog that the artists intended. Additionally, i 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 fromLEFT"and'RIGHT" level adjustment and fine tune the level of each channel with the volume knob or remote’ volume A/W keys.

ADJUSTING THE TONE CONTROLS

The L 54 is fitted with BASS and TRÉBLE tone controls to adjust the tonal balance of your system. Maximum and minimum values for bath 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 intellgibilty 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 545 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. fthe 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 L545'DISPLAY'button on the front panel. The selected audio input wil be displayed on the VFD after releasing the'DISPLAYbutton. The same procedure is applicable when assigning optical or analog audio to the VCR input. The assigned audio input wél always be recalled whenever that Input is selected via the front panel INPUT SELECT or the HTR 4 remote‘ input-select buttons. Itis not necessary to connect at the same time both analog audio and digital audio input for every video input you employ. K is preferable to make only digital audio link to the L 54 for audio playback This avoids possible confusion and ensures that the L 545 high performance digital audio circuitry wél always be employed!

ADJUSTING THE VOLUME

In addition to the Volume knob, use the HTR 4 VOL A/Y keys to adjust the volume ofthe L 54 raising or lowering the channels altogether. With HTR 45 VOL A /v keys, a momentary keypress will change the volume by 1 dB increments. I you hold down VOL A/v 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. À 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, ifthe prior setting is greater than 10 dB, the L 54 will power up at -10 dB. This prevents inadvertentiy beginning a session at excessive volume

Use the HTR 45 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 ircumstances: for example to reduce excessive deep bass (or enhance deep bass) by lowering (raising) the subwoofer level. Use the HTR 4S'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 contreller for most cases, we wil focus on remote-controlled operations. Be sure also to read the section, “Front Panel”

OPERATION USING THE L 54'S AM/FM RADIO The L 545 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 antennals) 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 ofits"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 por 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:

CHOOSING FM MUTE/MODE

The front-panel'FM MUTE/MODE"key is a dual-purpose control. In the normal position,"STand “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 ifthe 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. ABOUT RDS 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 wil 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:

When an RDS-enabled FM broadcast is tuned, after a brief delay the"RDS"symbol will light in the L545 front panel readout and the readout$ character section will show is 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 (AT) readout, if any, which might scroll song- or artist-name or any other text ofthe stations 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 ofthe 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 ofthese Obviousy, the most logical system is that you teach the codes from your DVD player to the [DVD] Device Selector“page! your televisions 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 HTR4 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 commandé 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 command to take their place, the underlying library. commands remain in place and can easy 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 t0 load one or more different code-libraries (see‘Loading Code Libraries below.

CONTROLLING THE L 54

The HTR4 is divided into two main sections. Eight Device Selector keys at the top—{AMP], [DVD] ET] and 50 on—set the handsets remaining keys to a “page” of commandk to control à particular component. A Device Select key determines only what component the HTR 4 will commande 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 ofthe function keys on the [AMP] Device Selector“page" perform L 54 functions. (The HTR4 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 ofthe Device Selector key-labeling correspondé 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 45 [AMP] Device Selector page is active, these keys select the Receiver inputs. Similarl, the purple [DVD] Device Selector“page" correspond to several purple labels, the green [TV] page to green labels, and 50 on.

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 fit 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 4 key: + On the HTR4, simultaneously press-and-hold [AMP] and A; the Learn LED turns steady green + Pressil (pause); the Learn LED turns amber. + Press [CD}; press (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 keys command remains unchanged. 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 à 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, simultaneous|y 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 or each function (you may switch devices while recording the macro as many times as necessary), allowing you to create macro containing command 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 ilumination will turn off. NOTE Each macro can store a maximum of 64 command steps. f 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: + Onthe HTR4, 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 D] (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 ilumination lights for 5 seconds. While it remains lit, press an HTR 4 key to which à macro has previously been stored. The corresponding macro will run; as each step executes, its parent" Device Selectar key flashes lights briefly: when execution is finished, the [MACRO] key ilumination 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 emnitter 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.

The HTR 45 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% [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 ilumination is the biggest drain on the HTR 45 batteries. A short key-illumination timeout will extend battery life appreciably: tuning it offaltogether (set it to 0 seconds) will lengthen it still further. FACTORY RESET The HTR4 can be reset toits factory state, deleting all learned commands, copied and punched- through keys, macros, and other setup information, reverting all keys to their pre-programmed library. commandé. To perform à factory reset simultaneously press-and-hold for 10 seconds the HTR 45 [ON] and IRTNI keys:the Learn LED will start to flash green. Release [ON and [RTNI 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 HTR4 can store leamed, 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 commandk on the IAMP]'page/) You can delete command by layers back'down'to the default library command on any key, removing learned commandé, punched-through functions, and copied keys. NOTE The default library commandé 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 keys 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.

The HTR 4 can store a different library of default NAD codes for each ofits Device Selector"pages® Ifthe 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 L'on/ not merely in standby). To enter the HTR 4% 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 HTR4 pointed toward the component, enter the first appropriate three-digit code-library number from the table below IFthe component turns off, press LENTER] to accept that code-library number and exit the Library Mode. Ifthe 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.

Now press-and-hold the HTR 45 [A] or [WI) 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 commandés; should you prove to have stepped past the needed code-ibrary, re-enter the Library Mode and use the cursor key to step back to it NOTE Ii possible that search mode will nd 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 45 operation with other-brand components.

You can check the current code-library on any Device Selector key as follows. Enter Library Mode by simultaneous|y pressing-and-holding for 3 seconds both the desired component 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. 1, the HTR 4 will flash [TAPE] 5 times, pause, and then flash For example, to indicate code-library [MACRO] once. You might wish to make a note of your components’ code-library numbers
