TABLE OF CONTENTS

THANK YOU FOR CHOOSING NAD

The L53 A/V Stereo 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 L53 delivers a range of genuinely useful options for Stereo and stereo listening alike, using powerful digital signal processing and
superbly accurate digital-audio circuitry. However, we have also been careful to ensure that the receiver 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 L53’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 NAD L53, and get the most from this
powerful and flexible home-theatre component.

One more thing: We urge you to register your L53 ownership on the NAD Worldwide Web site:

http://NADelectronics.com/w/Registration.html

For warranty information contact your local distributor.

UNPACKING AND SETUP
WHAT’S IN THE BOX

Packed with your L53 receiver you will find:

• An AM loop antenna

• An FM ribbon-wire antenna with balun

• The HTR L53 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 L53 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 receiver’s front panel and your
primary listening/viewing position-this will ensure reliable infrared remote control communications. The
L53 generates a modest amount of heat, but nothing that should trouble adjacent components. It is
perfectly possible to stack the L53 atop other components, but the reverse usually should be avoided.
Nonetheless, it is generally preferable that the L53 stands alone. It is especially important that sufficient
ventilation be provided; if you are contemplating locating the L53 within a cabinet or other furniture,
consult your NAD audio/video specialist for advice on providing adequate airflow.

SRS 3D AUDIO FROM SURROUND ENCODED MATERIAL

SRS (Sound Retrieval System), the leading 3D Sound technology in the world, is the result of many years
of research based on the psychoacoustics of sound and the dynamics of the human hearing system. SRS
retrieves the spatial information that is lost during the recording and playback process and restores the
original three dimensional sound-field. As a result, the reproduced sound is much closer to what the artist
originally intended and to that of a live performance. SRS 3D also eliminates the "sweet spot", filling the
listening environment with full rich sound. SRS 3D also delivers this same powerful 3D audio experience
over headphones.

SRS SURROUND MODE NOTES

• The SRS surround mode was intended for the playback of surround encoded material, such as
Dolby ProLogic movies, with only two loudspeakers in a standard stereo configuration. When used
in conjunction with this type of recorded material, the result is a large spacious sound with
enhanced directional cues.

• Using the SRS mode for the playback of normal stereo music recordings is not recommended, as
the results can be unpredictable and may sound distorted.

• This 3D Surround effect may not be available from some sources, such as those recorded with a
mono audio sound-track.

• Turn off the TV surround sound when using this 3D surround effect.

• For best 3D Surround effect it is recommended that the two speakers be positioned approximately
2m to 2.5m apart, and the listening position should be 2m to 2.5m away from the speakers.

GETTING THE MOST FROM THE NAD L53

ABOUT THE L53

Though the L53 is among the most technically sophisticated integrated A/V 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, including multichannel analog sources

• The L53 incorporates a high quality DVD player with exceptional playability. The player has support
for DVD video, VCD, SVCD with playback control (PBC), CD audio such as CD-RW as well as MP3.

• Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.

EASE OF USE

Despite the effort NAD has invested in the L53 receiver’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 L53 universal remote control is equally understandable, as are the L53’s own front-panel and on­screen displays (OSD).

ABOUT THE HTR L53 SYSTEM REMOTE CONTROL

Packed with your L53 is the NAD HTR L53 remote control, a full-system remote especially designed to be easy
to use and easy to understand. Be sure to read the section “Using the HTR L53 Remote Control,” to familiarize
yourself with the remote’s layout and operations before proceeding to setup your receiver.

Chances are, you will want to use your HTR L53 as your primary way to command your entire A/V system.
The HTR L53 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.

QUICKSTART

In case you simply cannot wait to experience the performance of your new NAD L53 DVD/Receiver, we
provide the following “Quickstart” instructions to get you underway. The steps below connect your L53
to a TV/monitor; be sure to read “Input Setup”.

PLAY A CD OR DVD MOVIE

• Connect the L53’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 L53’s “FRONT L and R” outputs, being 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 L53’s “SUBWOOFER
PRE-OUT” jack to its line input.

• Plug the AC mains plug into the AC; the LED on the front panel will be lit blue indicating the L53 is in
standby mode ready to accept commands from either the front panel power switch or the HTR L53 remote.

• To start playback of the DVD player; press the HTR L53 remote’s “DVD” Device Selector button, and
then its transport button “OPEN/CLOSE” to select the DVD, insert the media and press the transport

play button to start playing. 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 L53’s DVD on-screen menu systems
to check assignment of audio and video inputs; see “Input Setup”.

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 L53 carefully and completely.

ATTENTION!

Please make all connections to your L53 receiver 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.)

REAR PANEL

Identification of controls

1 SPEAKERS: Connect the left and right 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. (See
Figure 1 above)

NOTE

• Use stranded wire of at least 16-gauge (AWG); specialized speaker
cable may be valuable (consult your NAD audio specialist).
Connections to the L53 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 front speakers are rated to be 8
Ohms min. 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 of 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 L53 (or a

suitable replacement) is required for AM reception. Open the clip
terminal lever; insert the wire and close, 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 L53’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 L53 S-Video/composite video OUT jacks to these
components’ record-input. (Note that VCR may freely be used for
play-only components, in which case their IN 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).

6IRIN: 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 L53 from a remote location. Ask your dealer
or custom installer for further details.

7 OPTICAL & COAXIAL IN: Connect to the coaxial/optical S/PDIF-

format digital output of sources such as VCRs, HDTV or satellite
tuners, or other components; connect IN OPTICAL/COAXIAL to an
S/PDIF-format digital output. We recommend your source material
be set to PCM 2-channel format for these digital inputs.

NOTE

• During power-on from standby, there may be a momentary mute of
audio if CD/DVD-media is present in the L53's DVD tray, and either
Coaxial or Optical inputs are in use. This feature is normal operation
that allows the L53 to load the media's tables of contents and title
menus into memory. To avoid this momentary mute of audio,
remove the media from the L53's DVD tray before switching to
standby.

8 OPTICAL OUT: Connect the OUT OPTICAL port to the

corresponding S/PDIF digital input of a recording component such as
a CD recorder, DAT deck, or computer soundcard.

9 COMPONENT VIDEO OUT: Connect the L53’s “COMPONENT

VIDEO OUT” to the component-video input of a compatible video
monitor/TV. Be sure to observe consistency in connecting the
Y/Cr/Cb jacks (some source and TV components label these Y/Pb/Pr)
to the corresponding sources/inputs; do not rely purely on the colour
coding of the jacks, which may not always be consistent among
brands. The routing of the component-video output is fixed:
“COMPONENT VIDEO OUT” jack will only display the internal DVD
video signals.

NOTE

• The L53’s component-video output is a fully wide-band output,
compatible with all HDTV formats. The L53 will display its on- screen
menus on its component-video output.

10 AC POWER CORD: Connect AC power cord to the Voltage

according to the model, 120 V for US and 240 V for Euro models.

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 L53’s ON and OFF
buttons).

NOTE

• The total draw of all devices connected to this jack must not exceed
100 watts.

12 SCART/RGB VIDEO OUT (PAL only): Connect the L53’s

“SCART/RGB VIDEO 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. The routing of the SCART/RGB
input is fixed: the SCART/RGB VIDEO OUT” plug will only display the
internal DVD video signals.

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.

GETTING STARTED

Before you make the first connection to your L53, you should have the arrangement of your listening
room/home theatre 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.

NOTE

•

It is not absolutely necessary but one may find it easier to use the HTR L53 remote handset in conjunction
with the front panel buttons to configure your L53. See “Using the HTR L53 Remote”.

DEALING WITH HUM AND NOISE

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

• Power your system’s entire audio components 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, low­resistance 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 high­quality ones, is very thin and easily worn.

Track down hum/noise problems one component at a time, working backwards from the receiver. That
is: Connect the speakers to the receiver only, and check for hum. Then connect one component only (a
VCR, for example) alone, with no other components connected and check for hum. Connect additional
components, one at a time, to the receiver 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 adaptor) 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 L53 to factory default settings:

1) Place the L53 into FM mode.

2) Press quickly the three front panel buttons; “PLAY/PAUSE” then “STOP/OPEN” then “DISPLAY’,

holding the “DISPLAY” button for more than 7 seconds. The L53 will switch itself off then back
on to DVD mode.

NOTE

• Please note that setting the L53 to factory default settings will delete all AM and FM presets.

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT

The L53 receiver 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 L53 DVD OSD

While in DVD mode, press the L53’s “SETUP/MEMORY” button momentarily for the DVD’s OSD. With the
use of the HTR L53’s navigation buttons, you may select various menus. If the OSD does not appear, check
your “MONITOR OUT” connections either “COMPOSITE” or “S-VIDEO” outputs.

NOTE

• For convenience, the receiver’s OSD will appear on the L53’s component-video (NTSC/PAL),
SCART/RGB (PAL) output, and on the VCR record-outputs.

NAVIGATING THE DVD OSD AND MAKING CHANGES

Press the “SETUP/MEMORY” button on the front panel of the L53 as described above in “Displaying the
L53 DVD OSD”. Use the buttons of the HTR L53 to move up or down among the Setup menu’s list
of items; use “ENTER” to select a menu item, and use the ENTER button to change the parameter-value
of any item.
Select either “Save and Exit” or “Do Not Save and Exit” to store the selected values. Selecting “EXIT”
from the main setup menu exits the OSD altogether, retaining parameter-value changes, if any, made
previously.

NOTE

• When playing any DVD, VCD, or CD the L53’s DVD OSD can be activated at any time. This convenient
feature allows one to change audio and video settings “on-the-fly” without the need to stop or pause
the media.

INPUT SETUP

The L53 is equipped with 3 inputs; audio-video inputs labelled “CAB/SAT”, “VCR”, and “VIDEO 4”
(VIDEO 4 on the front panel) These will become active whenever that input is selected.

NOTE

• Incoming digital and audio signals present at either digital coaxial, optical or analogue are assigned to
their fixed inputs CAB/Sat and VCR. Assign Coaxial or Analogue to the CABLE/SAT input and Optical
or Analogue to the VCR input by toggling the L53's "DISPLAY" button through the choices shown in
the L53's fluorescent display.

INPUT SELECT

• From the front panel, press the “INPUT SELECT” button to toggle from DVD, CABLE/SAT, VCR, VCR,
VIDEO-4, AM Tuner, FM Tuner, and then back to DVD.

NOTE

• It is not necessary to have an analog audio input connected for every video input you employ. In fact,
in some cases-for example for a CABLE/SAT-it may be preferable to make only a coaxial digital audio
link to the L53 for audio playback. This avoids possible confusion, and ensures that the L53’s high­performance digital audio circuitry will always be employed.

• If you set the input to “ANALOG”, no incoming digital signal will be selected by that input. (Set an
input’s digital input to “ANALOG” only if you wish to ensure that that input will not play an incoming
digital bit stream, even if one is present.)

• The combination of analog-audio input and digital input assigned above will always be recalled
whenever that input is selected via the front-panel INPUT SELECT, or the HTR L53 remote’s input-select
buttons.

• That signals from digital inputs are not available on the analog VCR OUT jacks.

From the front panel or HTR L53 remote, select “AUDIO MODE”. Toggle through to SRS ON/OFF. Toggle
the SRS to on or off via the L53’s volume knob or the HTR L53 volume arrows

LEFT & 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.

From the
front L53’s front panel or HTR L53 remote select “AUDIO MODE”. Toggle from “LEFT” and “RIGHT” level
adjustment, fine tune the level of each channel with the volume knob or remote’s volume buttons.

ADJUSTING THE TONE CONTROLS

The L53 bass and treble controls are adjusted using the front panel’s “AUDIO MODE” button in
conjunction with the “VOLUME (SETUP)” knob; see “Front Panel”.

NOTE

• Bass/treble settings affect only the front left/right channels, not the subwoofer.

• The AUDIO MODE is “global”; that is, it remains in force with all inputs and in SRS mode.

ADJUSTING SUBWOOFER LEVEL TRIM “ON THE FLY”

You can make changes to the relative level of the 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

TO ADJUST LEVEL TRIM

Use the HTR L53 remote’s “SUB” buttons for direct-access level adjustment of this channel, over a
range of ±12 dB.

NOTE

• Channel Level changes made via the HTR L53 are retained even if you cycle the receiver through

standby.

You may operate the L53 DVD Stereo Receiver from its front panel or via the HTR L53 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”.

ADJUSTING THE VOLUME

Use the HTR L53 remote’s “VOL” buttons to adjust the “master volume” of the L53, raising or lower
all three channels together.

NOTE

• A momentary buttonpress will change the master volume by 1 unit increments; if you hold down
“VOL” buttons the master-volume change will “run-on” until the button 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.

• If muting has been activated, adjusting master-volume via the HTR L53 remote or the front-panel knob
automatically releases the mute function.

• The L53 will power-up from standby mode at whatever master volume setting was last used; however,
if the prior setting was greater than -10 the L53 will power up to -10. This prevents inadvertently
beginning a session at excessive volume.

MUTING THE SOUND

Use the HTR L53 remote’s “MUTE” button to silence all channels completely. Muting is always available,
regardless of source selection.

NOTE

• Cycling through standby or powering off releases muting; the L53 will return from standby with
muting off if standby was invoked with muting on.

• A changing input releases muting.

• Adjusting the master-volume via the HTR L53 or the front-panel volume knob automatically releases
the mute function.

SELECTING SOURCES

With the HTR L53’s remote’s “AMP” device selected, the remote’s numeric-button section directly selects
the receiver’s internal DVD and tuner “TUNER”, as well as the other inputs, refer to the orange labels
directly above each button.

• When a source other than the internal DVD is selected, the video signal at the monitor output is either
a black background, or the input video if present.

• When you change sources, the VFL will display the new input

When you want to play back DVD videodiscs, turn on the TV and select the L53’s DVD player. When you
want to experience the three dimensional sound-field of DVD videodiscs, VCDs, or audio CDs from the
L53, press the “AUDIO MODE” button on the L53 and select the SRS ON or OFF.

The HTR L53 Device Selector button “DVD” will enable the transport buttons beneath the HTR L53
navigation buttons. The source selector button “INPUT SELECT” on the L53 can also select DVD as well.
If the L53 is in standby mode, the “OPEN/CLOSE” button will also automatically select DVD mode.

Set the playback picture size according to the aspect ratio of the connected TV in the “SETUP/MEMORY”
OSD menus.

The L53’s internal AM/FM tuner offers very high quality sound from radio broadcasts. Note that reception
and sound quality will always be dependent to a degree 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
‘balun’ included adaptor, and should be fully extended to form a “T”. This folded-dipole antenna will
usually work best oriented vertically, with the arms of its “T” full 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 optimise 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.

SELECTING THE RADIO

Press the “INPUT SELECT” button on the L53 front panel, the HTR L53’s orange “TUNER” (the numeric 5
button), or the yellow “AM” and “FM” buttons to select the receiver’s radio mode. Each subsequent press
of either button will toggle the unit between its FM and AM bands.

TUNING STATIONS

Press “INPUT SELECT” on the front panel to select FM or AM frequencies. Press and hold “SCAN TUNE

” for more than 2 seconds to search up or down; the L53’s tuner will stop at the next
sufficiently strong signal it encounters. Pressing the “SCAN TUNE ” buttons momentarily
during the search process will stop the search.

NOTE

• As well as from the front panel, one can perform the Scan function from the HTR L53 remote using

the “TUNE ” buttons.

SETTING RADIO PRESETS

The L53 can store as many as 60 of your favourite radio stations for immediate recall; 30 FM stations and
30 AM. To store a radio preset, first tune the desired frequency (see above), then press the front panel
“MEMORY” button. Press the “PRESET , ” button to select the preset number. Then press the
“MEMORY” button once again.

NOTE

• The Radio Presets must be stored from the front panel; this setup function is not accessible from the

HTR L53 remote.

SELECTING RADIO PRESETS

Press “PRESET ” on the front panel to step up or down between presets; press and hold “PRESET

” to scroll continuously up or down. The HTR L53 remote’s “PRESET ” buttons work similarly.

DELETING A STORED PRESET

You can empty a preset by deleting the stored information.

• Select the preset to be emptied.

• Simultaneously press the front panel buttons DISPLAY and SETUP/MEMORY in the following order.

• 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.

• Release the DISPLAY button.

• The preset will then be deleted and "DELETED" scrolls on the display.

NOTE

• Empty presets will be skipped during preset tuning.

CHOOSING THE FM MUTE / MODE

The front-panel “FM MUTE / MODE” button is a dual-purpose control. First, it “toggles” the L53 between
stereo mute and unmuted mono reception (assuming that a multiplex-stereo station of sufficient strength
is tuned). FM Mute eliminates noise from “empty” FM frequencies but also mutes very weak or distant
stations. Toggling off the FM Mute will result in reduced noise 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

Toggling between FM Mute on or off also defeats the L53’s FM muting circuit. If you wish to listen to
a particularly weak or distant broadcast, toggle off the FM Mute and tune it manually.

ABOUT RDS

The Radio Data System (RDS) permits compatible FM receivers to display text determined by the
broadcaster. The L53 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 favourite 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 L53’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” button 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.

SPECIFICATIONS

• Controls up to 8 devices

• 44 function buttons

• Learns up to 352 commands

• Records up to 44 macros with a maximum of 64 commands each

• Configurable punch-through

• Button illumination with programmable timeout

• Upgradable

• Contains pre-programmed library of NAD remote codes for the L53.

The NAD HTR L53 is ready to operate the L53 receiver right out of the box, but it is really eight remotes
in one. Each of the 8 Device Selector buttons at the top of the handset can call up a new “page” of
remote-control codes to be transmitted by the remaining 44 buttons. 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 button on any page (see “Learning Codes From Other Remotes,” below).

The HTR L53 is already preprogrammed with a full complement of commands for the L53 receiver on its
“AMP”, “TUNER” and “DVD” 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 L53 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 L53, it should not be necessary to re-program any buttons on the HTR L53 “AMP”

and “DVD” page. However, in order for the HTR L53 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 L53

The HTR L53 is divided into two main sections. Eight Device Selector buttons at the top-“AMP”, “DVD,”
“TV,” and so on-set the handset’s remaining buttons to a “page” of commands to control a particular
component. A Device Select button determines only what component the HTR L53 will command; it does
not perform any function on the receiver. All of the remaining buttons are function buttons 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 L53.

However, the HTR L53 is already preprogrammed to operate the L53. All of the function buttons on the
“AMP”, “TUNER” and “DVD” Device Selector “page” perform L53 functions. (The HTR L53 can also
command many other NAD components, from its “CD” and “TAPE” pages.)

It is important to note that certain HTR L53 buttons perform different functions depending on the selected
Device Selector “page.” The colour of the Device Selector button-labelling corresponds to the labelling of
the function buttons. Most centrally, the orange “AMP” Device Selector “page” corresponds to the
orange input-select labelling adjacent to the numeric buttons: When the HTR L53’s “AMP” Device
Selector page is active, these buttons select the receiver inputs. Similarly, the red “DVD” Device Selector
“page” corresponds to several red labels, the green “TV” page to green labels, and so on.

LEARNING CODES FROM OTHER REMOTES

Begin by positioning the HTR L53 “nose-to-nose” with the source remote so the two devices’ infrared
windows are about 2 inches apart.

• Enter Learning Mode: On the HTR L53, simultaneously press-and-hold for 3 seconds both a Device
Selector button and the “OPEN/CLOSE” button (just below the “DISP” button), until the
Learn LED at the centre of the HTR L53 turns steady green.

• Press the HTR L53’s function button you wish to teach a command; the Learn LED will turn amber.

• Press-and-hold the function button on the source remote: The HTR L53’s Learn LED will flicker
amber for a second or two, then turn solid green. The command is learned.

• Press the HTR L53’s Device Selector button 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 button, by pressing the active Device Selector button before the learn
process is complete; the Learn LED will turn red.

Example: Learning “VCR Pause”:

Position the HTR L53 and your VCR player’s remote as described above.

• On the HTR L53, simultaneously press-and-hold “VCR” and ; the Learn LED turns steady
green.

• Press the HTR L53’s (pause) button; the Learn LED turns amber.

• Press-and-hold the VCR player’s remote’s pause button; the HTR L53’s Learn LED flickers amber and
then turns solid green. The command is learned.

• Press “VCR” again to exit the learning mode.

PUNCH-THROUGH

The HTR L53’s “punch-through” function allows you to retain a function button from one Device Select
“page” on another, so that, for example, the AMP “SURR MODE” function might still control the L53
when the DVD Device Selector page is active

NOTE

• The HTR L53’s “VOL” and “MUTE” buttons are pre-programmed as “punched-through” for all Device
Select pages: “VOL” will operate the L53’s master-volume regardless of the currently selected device.
The “SURR.” “CENTER,” and “SUB” Channel Volume controls similarly are pre-programmed as
punched-through.

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

Example: Punch-through the from the DVD “page” to the AMP “SURR MODE” button:

• On the HTR L53, simultaneously press-and-hold “DVD” and (OPEN/CLOSE); the Learn LED
turns steady green.

• Press “SURR MODE”; the Learn LED turns amber.

• Press “AMP” twice; the Learn LED turns green.

• Press “DVD” again to exit the learning mode.

COPY A COMMAND FROM ANOTHER BUTTON

You may copy a command from any HTR L53 button to any other. To copy a button function, after
entering the Learning Mode, and pressing the desired button to be copied to, simply press the device
button from which you wish to copy, having first pressed its Device Selector button if it resides on another
“page.” The status LED will turn green; press the Device Selector button again to exit Learning Mode.

Example: Copy the Pause command from the DVD page to the AMP button:

• On the HTR L53, simultaneously press-and-hold “AMP” and (OPEN/CLOSE); the Learn LED
turns steady green.

• Press (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-button) command , the copied-to button’s
command remains unchanged. If you punch-through to a command and then delete or over-write the
original button, 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
buttonpress. 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 SURROUND MODE, and begin playback-again, all from a single
buttonpress. The HTR L53 can store one macro on each of its function buttons (these exclude the Device
Selector buttons).

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” button and the HTR
L53 function button 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 buttons to be recorded into the macro, being
sure to first press the requisite Device Selector button 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” button 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” button to Turn on the L53, Select the DVD Input, and
Commence Playback:

• On the HTR L53, simultaneously press-and-hold “MACRO” and “0” (numeric zero); the Learn LED
turns steady green.

• Press “AMP”; press “ON”; press “1” (orange “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 button illumination lights for 5 seconds. While it
remains lit, press an HTR L53 button to which a macro has previously been stored. The corresponding
macro will run; as each step executes, its “parent” Device Selector’s button flashes lights briefly; when
execution is finished, the “MACRO” button illumination goes out. Pressing any other HTR L53 button
while a macro is executing will abort the macro. Remember that you must hold the HTR L53 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 L53’s button-illumination can be set to remain lit for 0-9 seconds. The default value is 5 seconds.

To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR L53’s “DISP”
and the “0-9” button, 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

• Button illumination is the biggest drain on the HTR L53’s batteries. A short button-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 L53 can be reset to its factory state, deleting all learned commands, copied and punched­through buttons, macros, and other setup information, reverting all buttons to their pre-programmed
library commands. To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR L53’s
“ON” and “RTN” buttons; the Learn LED will start to flash green. Release “ON” and “RTN” before the
second flash is complete; the Learn LED will turn red, indicate 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 L53 can store learned, copied, and “default library” commands on any single button. (The
default library commands are the pre-programmed NAD codes, such as the native L53 commands on the
“AMP” “page.”) You can delete commands by layers back “down” to the default library command on
any button, removing learned commands, punched-through functions, and copied buttons.

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 button’s Device
Selector button and the “RTN” button, until the Learn LED turns green. Press the function button 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 button again to exit Delete Mode.

NOTE

• You may delete multiple function-button 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.

LOADING CODE-LIBRARIES

The HTR L53 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 L53 to control is plugged in and powered-up
(“on,” not merely in standby). To enter the HTR L53’s Library Mode, simultaneously press-and-hold for 3
seconds both the desired Device Selector button and the “PROGRAM” button, until the Learn LED turns
green. While keeping the HTR L53 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 three­digit 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.

SEARCH MODE

If none of the codes from the table turn off 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
button and the “PROGRAM” button, until the Learn LED turns green. Now press-and-hold the HTR L53’s

or button; 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 button; 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 button 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
L53’s operation with other-brand components.

CHECKING CODE-LIBRARY NUMBER

You can check the current code-library on any Device Selector button as follows. Enter Library Mode by
simultaneously pressing-and-holding for 3 seconds both the desired component’s Device Selector button
and the “PROGRAM” button, until the Learn LED turns green. Press the “DISP” button; the HTR L53
indicates the current code-library by flashing its “TAPE”, “VCR”, and “MACRO” buttons. For example, to
indicate code-library #501 the HTR L53 will flash “TAPE” 5 times, pause, and then flash “MACRO” once.
You might wish to make a note of your components’ code-library numbers.
