SAFETY INFORMATION ELECTRIC POWER 1 Power Sources - Connect this unit only to power sources specified in the Operating Instructions, and as marked on the unit. 2 Polarization - As a safety feature, some units are equipped with polarized AC power plugs which can only be inserted one way into a power outlet. If it is difficult or impossible to insert the AC power plug into an outlet, turn the plug over and try again. If it still does not easily insert into the outlet, please call a qualified servi
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 mus

ABOUT THE S170 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 home- theater 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 (l

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

QUICKSTART In case you simply cannot wait to experience the performance of your new S170 preamplifier, we provide the following "Quickstart" instructions to get you underway. They assume that the DVD/CD player is connected to the VIDEO1 input and that the appropriate audio and video connections have been made. PLAY A DVD MOVIE (OR MUSIC CD) From the S70 remote's PREAMP menu, select [@ Source]; then press the [Source up] key until VIDEO 1 appears on the front-panel readout (and on-screen display,

SETTING UP THE S170 GETTING STARTED Before you make the first connection to your S170, you should have the arrangement of your listening room/home theater 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

ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT The S170 preamplifier employs a simple, self-explanatory system of on-screen display "menus" that will appear on the connected video monitor/TV, useful both during setup and in day-to-day operation. While the OSDs are always helpful, it is also perfectly possible to operate (or even set up) the S170 without them, because the same basic data is always shown, though sometimes in shortened form, on the preamp's own front-panel readout. DISP

CONFIGURING THE S170 You may set up your S170's levels, modes, and options in any order; it is not necessary to follow the order employed here. However, it is advisable to begin by configuring the S170's on-screen display options, since certain of these will affect the options made available to other setup routines. DISPLAY SETUP From the S170 OSD's Main menu, select the item using the remote's [Cursor up/down], and [Enter] keys. Using the [Cursor <>] keys, set: to "N

CONFIGURING THE S170 SPEAKER SETUP Every surround-sound system requires "bass-management" to direct low-frequency content from any or all channels to the speakers best able to reproduce it. In order for this function to operate correctly, it is very important that you correctly identify your speakers' capabilities. We use the terms "Small" and "Large" (and "No"), but note that physical size may be irrelevant. •A "Small" speaker is any model without significant deep-bass response, that is, below

The digital inputs will appear in order: Coax1-4, OPT 1, and Opt 2, followed by Off. You would set a source’s to “Off” if you wished to ensure that that source would not play an incoming digital bitstream.

USING THE S170 You may operate the S170 preamplifier equally from its front panel or via the S70 remote controller. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure to read the section, "Front Panel Operations," below. SELECTING SOURCES From the S70 remote's PREAMP menu, select [@ Source]; then use the [Source up/down] keys to cycle through all ten S170 inputs in order, beginning with the most recently selected one.
