User manual NAD S170I

[. . . ] 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. eNGLISH FRANÇAIS DEUTSCH ESPAÑOL ITALIANO PORTUGUÊS SVENSKA 2 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. PRECAUTIONS Read the Operating Instructions carefully and completely before operating the unit. All warnings and cautions in the Operating Instructions and on the unit should be strictly followed, as well as the safety suggestions below. [. . . ] If any other settings are in place, use the remote's [Cursor to the above conditions. ] and [Cursor ] keys to change them THX AUDIO SETUP THX Surround EX creates a sixth, "center-back" channel intended for reproduction by one or more loudspeakers located behind the listening area. With recordings bearing the Dolby Surround EX mark, this delivers a specifically engineered center-back channel that is encoded into the left/right surround channels-precisely as the center channel was encoded into the left/right front channels in matrix-encoded Dolby Surround mixes. However, the THX Surround EX processing will often produce a useful center-back effect even from software that was not, originally, deliberately encoded for EX playback. BASS LIMITER The S170i incorporates a Bass Limiter that you can set to eliminate any chance of your subwoofer producing audible distortion. You will do this by auditioning a built-in test-noise signal the S170i sends to your subwoofer, and increasing the Bass Limiter's "headroom" setting to the point of audible distortion. The Bass Limiter now prevents any program-material signals exceeding this level from being sent to the subwoofer. CONFIGURING THE BASS LIMITER From the <THX Audio setup> menu, use the remote's [Cursor ] and [Enter] keys to select the <Bass limiter setup> item. Using the same keys, set <Bass limiter> to "On" and <Limiter noise> to "On"; you will hear a soft rumbling from your subwoofer. (If you do not hear sound from the sub, check your subwoofer audio and power connections, check Speaker Setup, below, and/or check the subwoofer's own "hardware" control settings) Now use the remote's [Cursor ] keys to move to the <Limiter level> item, and [Cursor ] to decrease the limiter setting by 1 dB increments. Listen for the point at which audible distortions (harshening, "clacking, " "chuffing, " or other extraneous elements) become evident, then use [Cursor ] to return (increase) the limiter level by 1 or 2 dB until the distortion ceases. This establishes the "distortion-free" limit for your current subwoofer setup. It is advisable to return and re-check your Bass Limiter setup after you have completed the Level Setup routines (see below). Even after the Bass Limiter is set you may usefully engage its test-noise to "search and destroy" the room-rattles that are inevitably excited by high-level subwoofer output. (Window-treatments, electrical wall-plates, and hanging artwork are three common sources. ) · Should you ever change subwoofers, or reposition your current subwoofer or listening position, you should repeat the Bass Limiter setup routine. With a high-performance subwoofer, this routine can get rather loud. It is often best to await an opportune moment when spouses/children/pets are not at home to perform Bass Limiter setup fully. BOUNDARY GAIN COMPENSATION This THX Ultra 2 feature compensates for the audio gain (level increase) when the subwoofer is placed against a wall or near a room corner. ENGLISH 21 SVENSKA PORTUGUÊS ITALIANO ESPAÑOL DEUTSCH FRANÇAIS NOTE This feature is only applicable when using a THX Ultra 2 certified subwoofer for which the frequency response and sensitivity are part of the specification. Select <THX Ultra2 Sub> using the remote's [Cursor ] keys, then select <Yes> or <No> using the remote's [Cursor ] keys. Then using the remote's [Cursor ] keys select <Boundary gain comp. [. . . ] If you need more than a 1 second delay between particular commands-for example, to permit a component to power up completely-you can record "empty" steps into the macro. For example, if the [TITLE] key is not used for your CD player, you could record that command into the macro to insert a delay. KEY-ILLUMINATION TIME-OUT The HTR 2's key-illumination can be set to remain lit for 0-9 seconds. To set the illumination time-out, simultaneously press-and-hold for 3 seconds both the HTR 2's [DISP] and the [0-9] key, with the digit corresponding to the desired time-out duration; the Learn LED will flash twice to confirm the new setting.
