GETTING THE MOST FROM THE NAD S170
Thank you for choosing NAD.
The S170 A/V Surround Sound Preamplifier is one of the most technologically advanced surround-audio processor/preamplifiers yet devised, incorporating advanced, ultra-high-speed 32-bit digital signal processing, an architecture that is fully upgradeable (in both hardware and software), and extraordinarily precise 24-bit precision/96 kHz-sampling digital-to-analog conversion for all channels.
More importantly, it is among the most musically transparent and spatially accurate designs available, the culmination of everything we've learned, over a quarter-century, about music and home-theater sound reproduction. With our company's "Music First" design philosophy as its guiding design principle, we're confident that the S170 will make good on our promise to you of delivering both a state-of-the-art surround home-theater experience, and genuinely audiophile-quality music listening, for many years to come.
We urge 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 S170, and get the most from this powerful and flexible hometheater component.
One more thing: We urge you to register your S170 ownership on the NAD Worldwide Web site:
HTTP://NADELECTRONICS.COM/W/REGISTRATION.HTML
This is by far the best way to ensure that we at NAD world headquarters can inform you of possible future software and firmware updates, changes that might significantly enhance the performance and utility of your S170. Please also send in your warranty card, so that your local NAD organization will have a record of your purchase, and save your original purchase receipt. This will assure you of warranty service in your area.

UNPACKING AND SETUP
WHAT'S IN THE BOX
Packed with your S170 preamplifier you will find:
•A removable AC cable (if you wish, any IEC-standard AC cable of suitable wattage may be substituted).
•1 DC trigger cable.
•The S70 remote controller with operating manual and 9v (PP-3) battery.
•A pair of white cotton gloves—for handling your S170 during setup without fear of scratches or fingerprints marring its finish.
•This owner's manual.
SAVE THE PACKAGING
Please save the box and all of the packaging in which your S170 arrived. Should you move or otherwise need to transport your preamplifier, 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
We hope you will agree that the S170's finish quality and appearance earn it pride of place in any home theater or music system. 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 preamp's front panel and your primary listening/viewing position—this will ensure reliable infrared remote control communications. Due to the S170's high-speed DSP hardware and high-current audio circuits it generates a modest amount of heat, but nothing that should trouble any adjacent components. It is perfectly safe to stack additional components atop the S170, or vice versa, but it is generally preferable (and considerably handsomer) if the S170 stands alone. The one exception is a power-amplifier or receiver, or any other unit that generates substantial heat: The S170 should not be stacked above or below any such component.

Though the S170 A/V preamp is among the most powerful and sophisticated digital-surround decoder/processors available, we worked hard to make it one of the most musically transparent hometheater components as well; this is what we mean by NAD's "Music First" design philosophy. Here are just a few examples:
•The S170 employs the latest, most sonically pure high-performance FET components throughout its analog audio circuits
•Exceedingly low output impedance from all channels (long an NAD hallmark) eliminates sonic impact from cables and amplifier input-impedances
•Output muting is via reliable, sonically transparent gold-contact relays rather than sound-coloring electronics
•Gold-surfaced connectors are employed throughout both internally and externally to ensure unimpeded signal transfer.
E.A.R.S.
A key element of the S170's unique musicality is NAD’s proprietary Enhanced Ambience Recovery System (EARS). In sharp contrast to many "ambience-synthesis" music-surround modes, EARS exploits the S170’s substantial DSP power to route the ambient content that is "encrypted" in virtually all natural-acoustic recordings to the appropriate main, center 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.
On the digital side, the S170 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 (and A/D conversion for analog inputs processed for surround sound) for all channels. A single, high-precision master clock runs all digital circuits to eliminate the timing errors ("jitter") that otherwise occur between digital stages, compromising sonic performance. The result is legitimately state-of-the-art surround decoding from Dolby Digital and DTS sources in both 5.1-channel and 6.1/7.1-channel output modes, and genuinely superior sound quality in all modes.
ABOUT THX
The S170 preamplifier is certified by Lucasfilm Ltd. as meeting the rigorous requirements of its home THX/Ultra program for surround controllers. This means that it is capable of delivering an audio experience equal to that of the finest commercial cinemas when its superb fundamental performance is combined with the surround enhancements mandated by the THX/Ultra program.
EASE OF USE
While we expended enormous effort to ensure that the S170 preamplifier's sonic performance is second to none, we invested no less in making it powerfully easy to use. Its design is unusually simple for so sophisticated a component, and the S70 LCD remote controller's functioning is uniquely self-prompting and intuitive, as are the S170's own front-panel and on-screen displays. A simple yet powerful system of presets will permit you to fine-tune your listening setup for different conditions, and to recall these multiple parameters with a single keypress.
INTEGRATION
The S170 preamplifier offers extensive, flexible system-integration options through its two configurable DC triggers outputs, as well as via NAD's proprietary NAD Link inter-component communications protocol. Additionally, an RS-232 serial port stands ready to integrate the preamp with still more sophisticated controllers such as touch-screen systems and whole-house automation installations by offering two-way communication.

ABOUT THE S170
UPGRADABILITY
We engineered the S170 preamplifier with selectively modular construction. All of its digital-control and - processing “intelligence” is located on a single plug in module. This sophisticated yet accessible architecture simplifies servicing while maintaining signal-path integrity, making potential hardware upgrades possible. That said, given the S170's extraordinary processing power and speed we do not foresee the need for hardware upgrades at this time. Nevertheless, you may feel confident that the S170 will not become obsolete in the foreseeable future.
Software upgrades are a more likely scenario, and are easily accomplished via the high-speed RS-232 port on the rear panel of the S170. Owners who have registered their S170s on our international web site at www.NADelectronics.com will be advised of updates (see "Getting the Most from the NAD S170," above). Updates may be free of charge, or in some cases may require royalty payments for proprietary decoding systems and the like. Computer-savvy users can perform these upgrades by downloading the files (and an installer application) from our web-site, and uploading to the S170 by connecting the preamp's RS-232 port to the PC's serial port. (See “System Integration”, page 26 for more detailed information). Alternatively, the NAD audio specialist from whom you purchased your S170 will assist you in performing software upgrades.
ABOUT THE S70 SYSTEM REMOTE CONTROL
Packed with your S170 is the NAD S70 LCD remote controller, accompanied by a short, dedicated operating manual covering its general function. We strongly recommend that you scan this manual and familiarize yourself with the S70's simple layout and operations before proceeding with setup of your S170 preamplifier; you will find that this process takes but a few minutes.
The S70 remote controller is a "paged" display; that is, each set of commands or functions shows a new array of icons on its LCD screen. This makes it a powerfully flexible commander; however, because we were careful to keep its menu structure very "shallow"— there are never more than three levels between any command and the uppermost, "top" screen—you will find it simple and intuitive to use.
Chances are, you will primarily use your S70 to command the S170 A/V preamp, but the remote can also operate other Silver Series and C-Series NAD components such as a CD player or recorder, cassette-tape component, and an AM/FM tuner. You will find the details of its function with these components in each of their owner's manuals.
