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.

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).
