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:

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:

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.

Introduction

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”.

PLAY A DVD MOVIE

Connect the L70’s composite video or S-Video “MONITOR OUT” jack to your TV/monitor’s corresponding input.

Depending on the selection above, switch the “OSD SELECTOR” switch to either S-Video or Composite position (found on the back of the L70 beside the Composite Output “MONITOR” jack.

Connect your left and right front speakers to the L70’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. (Connect centre and surround speakers as well, if you like). If your system includes 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.

1 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 key (or the HTR L70’s ON and OFF keys).

NOTE

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

2AC POWER CORD: Connect AC power cord to the Voltage according to the model, 120 V for US and 240 V for Euro models.

3MONITOR 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.

4OSD SELECTOR: This switch places the OSD (On Screen Display) to either the Composite or S-Video MONITOR OUT.

5COMPONENT 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

6FM 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.

7AM 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.

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 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.

8

8SCART/RGB VIDEO OUT (PAL only): Connect the L70 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: 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/PDIFformat 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.

1112 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.

12PRE-OUT SUBWOOFER: Connect this output to a powered (“active”) subwoofer (or to a power amplifier channel driving a passive system).

135.1 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.

Identification of controls

REAR PANEL

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.”

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 copperand 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).

Setup

SETTING UP THE L70

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.

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.
