THANK YOU FOR CHOOSING NAD
The L70 A/V Surround Sound 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 L70 delivers a range of genuinely useful options for surround sound 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 L70’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 L70, and get the most from this
powerful and flexible home-theatre component.
One more thing: We urge you to register your L70 ownership on the NAD Worldwide Web site:
http://NADelectronics.com/w/Registration.html
For warranty information contact your local distributor.

GETTING THE MOST FROM THE NAD L70
UNPACKING AND SETUP
WHAT’S IN THE BOX
Packed with your L70 receiver you will find:
• An AM loop antenna
• An FM ribbon-wire antenna with balun
• The HTR L70 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 L70 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
L70 generates a modest amount of heat, but nothing that should trouble adjacent components. It is
perfectly possible to stack the L70 atop other components, but the reverse usually should be avoided.
Nonetheless, it is generally preferable that the L70 stands alone. It is especially important that sufficient
ventilation be provided; if you are contemplating locating the L70 within a cabinet or other furniture,
consult your NAD audio/video specialist for advice on providing adequate airflow.
ABOUT THE L70
Though the L70 is among the most technically sophisticated integrated A/V & 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:
ESPAÑOL
ITALIANO
PORTUGUÊS
SVENSKA
• High-performance components used throughout the receiver’s analog audio circuits maximize
quality from all sources, including multichannel analog sources such as DVD-Audio and SACD.
• The L70 incorporates a high quality DVD player with exceptional playability. The player has support
for DVD video and audio, VCD, SVCD with playback control (PBC), CD audio such as CD-RW as
well as MP3. As with all NAD DVD players, a set of convenient navigation buttons is provided on
the front panel. See “Front Panel Controls”.
• Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.
E.A.R.S. AND DIGITAL SURROUND
A key element of the L70’s unique musical aptitude is NAD’s proprietary Enhanced Ambience Recovery
System (EARS). In sharp contrast to many “ambience-synthesis” music-surround modes, EARS exploits the
L70’s substantial DSP power to route the ambient content that is “encrypted” in virtually all naturalacoustic recordings to the appropriate main, centre and surround speakers, without resorting to artificially
generated reflections or regeneration. EARS’ natural ambience yields a subtle but exceptionally effective
surround mode that naturally enhances the spatial presentation in a fashion suitable for serious music
listening. Dolby ProLogic II Music, Movie and Emulation modes can also create enjoyable experiences from
2-channel sources.
On the digital side, the L70 combines extraordinarily high-speed DSP processing employing one of the
most advanced high-speed DSP “engines” available, with fully 24-bit, 96 kHz-sampling-capable D/A
converters for all channels. A single, high-precision master clock synchronises all digital circuits to eliminate
the timing errors (“jitter”) that otherwise compromise sonics. The result is legitimately state-of-the-art
surround decoding from Dolby Digital and DTS sources, and 5.1-channel reproduction, with genuinely
superior sound quality in all modes.

GETTING THE MOST FROM THE NAD L70
EASE OF USE
Despite the effort NAD has invested in the L70 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 L70 universal remote control is equally understandable, as are the L70’s own front-panel and onscreen displays (OSD).
UPGRADABILITY
The L70 receiver permits flexible system growth via individually accessible 5.1 channel input for
connectivity to products with integrated surround decoders.
See “Rear Panel (5.1 CH. INPUT)”.
ABOUT THE HTR L70 SYSTEM REMOTE CONTROL
Packed with your L70 is the NAD HTR L70 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 L70 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 L70 as your primary way to command your entire A/V system.
The HTR L70 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 L70 DVD/Receiver, we
provide the following “Quickstart” instructions to get you underway. The steps below connect your L70
to a TV/monitor; be sure to read “Input Setup”.

a powered subwoofer, connect the L70’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 L70 is in
standby mode ready to accept commands from either the front panel power switch or the HTR L70 remote.
•To start playback of the DVD player; press the HTR L70 remote’s “DVD” Device Selector key, and then
its transport key “Open/Close” to select the DVD, insert the media and press the transport play
key to start playing. You should hear multichannel or 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 L70’s Receiver or 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 L70 carefully and completely.

NOTE
The total draw of all devices connected to this jack must not exceed
100 watts.
2 AC POWER CORD: Connect AC power cord to the Voltage
according to the model, 120 V for US and 240 V for Euro models.
3 MONITOR OUT: Connect to video input of the monitor/television,
using quality dual-RCA and/or S-Video cables designed for video
signals. In general, the S-Video connection is superior and should be
used if your TV/monitor provides the corresponding input.
4 OSD SELECTOR: This switch places the OSD (On Screen Display) to
either the Composite or S-Video MONITOR OUT.
5 COMPONENT VIDEO OUT (NTSC only): Connect the L70
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 input
is fixed: COMPONENT VIDEO OUT jack will only display the internal
DVD video signals.
NOTE
The L70’s component-video output is a fully wide-band output,
compatible with all HDTV formats. The L70 does not display its onscreen menus on its component-video output. To use on-screen

6 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.
7 AM ANTENNA: The AM loop antenna supplied with the L70 (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. Do not remove the AM loop antenna.

SCART/RGB plug will only display the internal DVD video signals.
NOTE
The L70 does not display its on-screen menus on its SCART/RGB
output. To use on-screen menus, you will need to make an S-Video
or composite connection between the L70 and the monitor/TV, and
select it for menu display. Refer to OSD SELECTOR.
9 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. See “Setup.”
10 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.
11 12 V TRIGGER OUT: This mini-jack will control on or off any auxiliary
equipment with a 12V trigger input when the L70 switches from
standby to on state respectively. The maximum current this output
can handle is 50 mA at 12 V. Consult your NAD audio specialist for
more information.
12 PRE-OUT SUBWOOFER: Connect this output to a powered
(“active”) subwoofer (or to a power amplifier channel driving a
passive system).
15 SPEAKERS: Connect the left and right front, centre, and left and
right surround speaker outputs 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.
NOTE
• Use stranded wire of at least 16-gauge (AWG); specialized speaker
cable may be valuable (consult your NAD audio specialist).
Connections to the L70 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 front, centre, and surround speakers
are rated to be 8 Ohms min. per speaker.
IMPORTANT NOTE
For optimum surround performance, the L70 SPEAKER
CONFIGURATION and levels must be set correctly via the receiver’s
setup routines; see “SPEAKER CONFIGURATION.”

13 5.1 CHANNEL INPUT: Connect to the corresponding analog audio
outputs of a multichannel source component such as a DVD-Audio
or multichannel-SACD player, or external multichannel decoder.
NOTE
There is no bass-management or other processing (other than
master-volume control) available to this 5.1 CHANNEL INPUT. While
the multi-channel audio outputs of a DVD-Video player can be
connected to these jacks, using the L70’s own Dolby Digital and DTS
decoding and digital-analog converters, via a digital connection, can
usually produce superior results.
14 CABLE/SAT & VCR: These comprise the L70’s principal inputs.
Connect S-Video, composite video, and analog stereo audio from
source components such as HDTV/satellite tuners (see “Setup”). VCR
may be used with recording components such as videocassette or
DVD-recorders; connect the L70 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.)
NOTE
For best results when recording to a VCR, select “SURROUND:
STEREO”, and SUB: OFF in the receiver’s setup OSD.

Setup
SETTING UP THE L70
GETTING STARTED
Before you make the first connection to your L70, 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 L70 remote handset in conjunction
with the front panel buttons to configure your L70. See “Using the HTR L70 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.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT
The L70 receiver employs two; self-explanatory systems of on-screen display “menus” one for the L70
receiver, the other for the internal DVD player. These “menus” will appear on the connected video
monitor/TV and are required during the setup process (useful in day-to-day operation); so be sure to
connect the monitor/TV before proceeding with setup.
NOTE
The receiver’s on-screen displays (OSD) are carried to either one of the S-Video or composite MONITOR
OUT jacks as defined by the receivers OSD SELECT switch. In addition to the receiver’s OSD, there is
an internal DVD’s OSD; designed for greater enjoyment and flexibility when watching DVD/CDs by
allowing simultaneous output of the OSD on S-VIDEO, COMPOSITE, COMPONENT (NTSC models) and
SCART/RGB (PAL models).
10
DISPLAYING THE L70 RECEIVER’S OSD
While in DVD mode, press the L70’s “SETUP” key momentarily for the DVD’s OSD, and for 3 seconds for
the receiver’s OSD. With the use of the navigation keys either on the L70’s front panel or the HTR L70
remote, you may select various menus. For the L70’s receiver, the <MAIN MENU> will display on your
video monitor/TV. If the OSD does not appear, check your MONITOR OUT connections either COMPOSITE
or S-VIDEO outputs, in conjunction with position of the OSD SELECT switch. Use the OSD Select switch
located on the back of the L70 beside the MONITOR OUT jacks to switch the OSD between COMPONENT
and S-VIDEO.
NOTE
The receiver’s OSD does not appear on the L70’s component-video (NTSC) or SCART/RGB (PAL) output,
nor does it appear on the VCR record-outputs; these are for recording, not monitoring during receiver
operation.
Setup
SETTING UP THE L70
ENGLISH
NAVIGATING THE OSD AND MAKING CHANGES
Press the SETUP button on the front panel of the L70 as described above in “Displaying the L70 Receiver’s
OSD”. Use the keys of the HTR L70 or on the front panel, to move up or down among the Setup
menu’s list of items; use “Enter” to select a menu item, and use to change the parameter-value
(setting) of any item. Selecting <MAIN MENU OFF> from the main setup menu exits the OSD altogether,
retaining parameter-value changes, if any, made previously.
When in the DVD OSD, pressing the “SETUP” button on the L70 will toggle off the dedicated DVD OSD
and at that moment the DVD settings will be stored.
NOTE
When playing any DVD, VCD, or CD the L70’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.
SETTING L70 OSD LANGUAGE (RECEIVER SECTION ONLY)
From the OSD’s <MAIN MENU> screen, select the <LANGUAGE> item using the remote's and
“Enter” keys. Using the keys, select between English, French or German for the L70’s receiver OSD.
INPUT SETUP
The L70 is equipped with four configurable inputs; 3 audio-video inputs labelled CAB/SAT, VCR, and
VIDEO 4 (VIDEO 4 on the front panel), and one set of audio-only labelled 5.1 CHANNEL INPUT. These will
become active whenever that input is selected.
NOTE
Incoming digital and audio signals present at either digital (either coaxial or optical) or analog inputs
are mutually exclusive. Any audio signal can be permanently selected toggling the L70’s “DISPLAY”
button through the choices shown either in the L70’s fluorescent display and OSD.
