SAFETY INFORMATION
EXPLANATION 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.
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.
INSTALLA ALLATION INSTALLATION
1 Water and Moisture - The apparatus shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the apparatus. 2 Heat - Do not use this unit near sources of heat, including heating vents, stoves, or other appliances that generate heat. [. . . ] We use the terms "Small" and "Large" (and "Off"), but note that physical size may be irrelevant. · A "Small" speaker is any model, regardless of physical size, that lacks significant deep-bass response, that is, below about 80 Hz. · A "Large" speaker is any full-range model, that is, one with deep-bass response · An "Off" speaker is one that is not present in your system. For example, you might not have any surroundback speakers installed; in that case, you would set the <Surr Back> setup item to "OFF". Depending on the relationship between speakers, the possible selections for each speaker are as follows: Front L/R Center Surr. L/R Subwoofer
LARGE LARGE SMALL OFF LARGE ON LARGE SMALL SMALL OFF LARGE OFF SMALL OFF SMALL SMALL OFF SMALL OFF SMALL OFF ON or OFF
SPEAKER SETTINGS
From the OSD's main <Setup> menu select the <Speaker Settings> line using the HTR 2 remote's [ / ], and [Enter] keys. Using the [ / ] keys, set <Front:> to "Large" or "Small" as your main-front speakers require according to the guidelines noted above. Similarly, set <Center:>, <Surround:>, and <Surr Back:> to "Large, " "Small, " or "Off" as your system's loudspeakers require. Set <Sub:> to "On" or "Off, " selecting "On" only if you have a subwoofer connected to the T 743's SUB analog output jack. NOTE: The Speaker Settings configuration is "global"; that is, it remains in force with all inputs and in all listening modes. However, speaker settings are part of the T 743's Preset system; consequently, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require. NOTE: You can set Subwoofer to "On" even with "Large" front speakers, in which case bass content from any channels set to "Small" will be routed to both the subwoofer and to the front speakers; LFE-channel signal will pass only to the sub. In most subwoofer-equipped systems, setting front speakers to "Small" is usually the better option.
LISTENING MODE
From the OSD's main <Setup> menu select the <Listening Mode> line using the HTR 2 remote's [ / ], and [Enter] keys. Using the [ / ] and [ / ] keys you can select mode variations, and adjust various parameters, depending on the current Listening Mode. For more information, see "About the T 743's Listening Modes". See "Creating and Using Presets, " below; NOTE: The Listening Mode used the last time a given input was selected will be recalled the next time that input is selected, unless overridden by a Dolby Digital or DTS signal, which automatically invoke their native Listening Modes.

CHANNEL-BALANCE (TEST) SETUP
Adjusting the relative balance of your system's loudspeakers ensures that surround-sound recordings, whether music or film, will present the balance of effects, music, and dialog that the artists intended. Additionally, if your system incorporates a subwoofer it establishes a correct relationship between the volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic elements.
USING AN SPL METER
It is quite practical to perform the T 743 Level setup routines "by ear, " and careful work will produce acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter, such as Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable. Ownership of such a meter could prove a valuable audio tool; your NAD audio specialist may be able to help you with temporary use of a meter. The SPL meter should be placed at the primary listening position, at approximately the height of the seated listener's head. A tripod is helpful, but with a little duct tape almost anything -- a pole lamp, music-stand, or ladder-backed chair, for example -- can do as well. Just be sure that no large acoustically reflective surfaces obstruct or are near the microphone element.

LOADING CODE-LIBRARIES
The HTR 2 can store a different library of default NAD codes for each of its Device Selector "pages. " If the original default library does not control your NAD CD player, tape deck, DVD player, or other component, follow the procedure below to change the code-library. Begin by ensuring that the component you wish the HTR 2 to control is plugged in and powered-up ("on, " not merely in standby). To enter the HTR 2's Library Mode, simultaneously press-and-hold for 3 seconds both the desired Device Selector key and the [A/V PRESET] key, until the Learn LED turns green. While keeping the HTR 2 pointed toward the component, enter the first appropriate three-digit code-library number from the table below. [. . . ]
