  • Page 2: Safety Information

    SAFETY INFORMATION EXPLANATION OF GRAPHICAL SYMBOLS The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

    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.

  • Page 6: Unpacking And Setup

    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...

  • Page 7: 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: •...

  • Page 8: Upgradability

    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).

  • Page 9: Quickstart

    Start playback of the DVD/CD player. From the S70 remote's PREAMP menu, select [MODE/MULTI.S]; then press the [Mode •] key; the [Cursor up/down] keys will now cycle through all of the S170 listening modes that are available for the current input signal type (see "About the S170's Listening Modes," below).

  • Page 10: Front Panel

    FRONT PANEL 1 POWER: Switch off to disconnect the S170 from all AC power and exit the Standby mode. Switching POWER on both reconnects the AC and actively power-up the preamp. 2 STANDBY: Illuminates when the S170 is in the Standby mode (dark when preamp is on, or powered-off).

  • Page 11: Attention

    ATTENTION! Please make all connections to your S170 preamplifier with the unit powered off or unplugged. (It is equally wise to power-down or unplug all associated components while making or breaking any signal or AC power connections.) 1 COMPOSITE VIDEO IN 1-6: Connect Video Inputs 1-6 to composite- video from source components (see "Source Setup,"...

  • Page 12: Setting Up The S170

    USING THE S70 REMOTE You will likely find it most convenient to use the S70 remote handset to configure your S170. The remote is a "paged" display; that is, each set of commands or functions shows a new "page" of icons on its LCD screen.

  • Page 13: About The On-Screen Displays (Osd) And Front-Panel Readout

    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.

  • Page 14: Configuring The S170

    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.

  • Page 15: Audio Setup

    Using the [Cursor <>] keys, you may decrease the LFE channel setting by as much as 10 dB in 1 dB decrements. • In most systems the LFE channel setting may be left at 0 dB (no change), because the S170's Bass Limiter (see below) will be set to prevent subwoofer overload. However, if your subwoofer's headroom is known to be limited, or if the low-frequency effects of film soundtracks generally seem excessive in your system, you might profitably try decreasing the <LFE channel>...

  • Page 17: Speaker Setup

    NAD audio specialist may be able to help you with temporary use of a meter. Calibrating your system with an SPL meter also permits you to set its overall level so that, when the S170's Master Volume control is set to -0 ("reference level"), the playback in your home theater matches the loudness of the same film...

    3 audio-only inputs (labeled CD, AUX, and TUNER). There is also an audio-only TAPE MONITOR loop. For each input position of the S170, you may select a digital input to become active whenever that input is selected, and you may assign a 7-character name which will be displayed on the front-panel display and momentarily on the on-screen display whenever that input is selected.

    #1 to the 12V TRIGGER input jack on the S250 power amplifier. Note that this custom cable provides an 1/8th-inch mini-plug on one end for the S170, and a special, DC-style plug on the other to fit the S250 amplifier's trigger input.

    "back"-channel speakers, plus subwoofer (if any). If Dolby Digital EX/DTS ES encoding is present in the original recording its logic is used to derive the back channels; otherwise, the S170 preamplifier derives a single surround-back channel from the left/right surround channels.
  • Page 22 DVD or other recording's soundtrack selection is set to "stereo/PCM" rather than "5.1" or equivalent. ANALOG BYPASS Stereo or monaural recordings from any S170 source's analog input jacks are routed directly to the left- right-front outputs with no processing whatsoever. Use Analog Bypass to reproduce minimal-signal-path "audiophile" conditions for critical listening of two- channel (or monaural) sources.
  • Page 23 From the S70 remote's PREAMP menu, select [MODE/MULTI.S]; then press the [Mode •] key; the [Cursor up/down] keys will now cycle through all of the S170 listening modes that are available for the current input signal type (see table, above).

    Preset in force. NOTE THAT: • The selected Preset remains in force until you select a different Preset, or cycle the S170 through its Standby mode. • A Preset applies regardless of what source is selected, or what listening mode is in operation.

  • Page 26: Front Panel Operations

    USING THE S170 FRONT PANEL OPERATIONS It is possible to perform every function directly from the S170 Preamplifier's front panel, without the S70 remote controller. • To change input sources or listening modes, press AUDIO or Video or MODE; the VOLUME (SETUP) knob will now cycle, bi-directionally, through all audio-video or audio-only sources, or listening modes.

  • Page 27: Listening In A Remote Zone (Multisource)

    • Only analog-input sources are available for selection at the MULTISOURCE OUT jacks. For example: If a DVD/CD player is connected to the S170 only via its digital output, its playback will not be heard from the MULTISOURCE OUT jacks; to make it available for MultiSource use, also connect the DVD/CD player's stereo-analog outputs to the S170's corresponding VIDEO1-5 analog input.
