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 natural-
acoustic 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.
