[. . . ] After all positions are measured, the DSP calculates the ideal system response for your particular room and speaker setup. If some inconsistencies or discrepancies are detected during the Audyssey calibration, the process maybe interrupted or the problem is shown in the particular setup window. After following and undertaking the displayed instructions, re-start the Audyssey calibration again. When the measurements are finalized, Audyssey calculates the ideal system response for your particular room and speaker setup. NOTE Thetesttoneemittedduringmeasurementisloud.

NEXTATARGETCURVEMUSTBECHOSEN Because loudspeaker designers assume that their products will be used in typical domestic rooms, they are `voiced' to work in this environment. It is assumed that the room will add some bass reinforcement and will absorb some treble energy. Thus if we effectively `remove the walls with room correction, and set the speakers for flat response, you may find this sounds too bright in the treble and too weak in the bass region. NAD engineers have done extensive research in this area of room acoustics, and along with Audyssey engineers developed what we believe is the ideal `in room' response curve. We include this NAD EQ, along with an Audyssey developed EQ as the two best choices. The response curves shown below typify NAD EQ room correction process. Room Response measured by Audyssey microphone Inverse Correction Filter calculated by NAD T775 Corrected Room Response Select the Target Curve you find to be most satisfactory by pressing the Audyssey key of the remote. It is recommended that you take full advantage of the T 775's Audyssey Auto Calibration feature for your speaker setup. However, if you desire to setup your speakers manually or if you already had run Audyssey Auto Calibration but would like to make adjustments, the following sections on Speaker Configuration, Speaker Levels and Speaker Distance can also be followed and implemented.

NEDERLANDS DEUTSCH ITALIANO ESPAÑOL FRANÇAIS ENGLISH OPERATION USINGTHET775­SETUPMENU ENGLISH FRANÇAIS ESPAÑOL LARGE SPEAKER CONFIGURATION 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. For this function to operate correctly, it is important that you correctly identify your speakers' capabilities. 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 surround-back speakers installed; in that case, you would set the `Surround' setup item to "Off". Depending on the relationship between speakers, the possible selections for each speaker are as follows: Front L/R Center Surround L/R LARGE LARGE SMALL OFF LARGE SMALL SMALL OFF LARGE OFF SMALL OFF SMALL SMALL OFF SMALL OFF SMALL OFF Back LARGE SMALL OFF LARGE SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF SMALL OFF OFF SMALL OFF OFF Subwoofer 1/2 ON or OFF ITALIANO DEUTSCH NEDERLANDS SVENSKA ON The Speaker Configuration is "global"; that is, it remains in force with all inputs and in all listening modes. Consequently, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require. Speaker Configuration can be managed and adjusted by pressing a combination of and then keys. [. . . ] · Correct `Speaker Configuration' or 'Speaker Levels' settings. No sound from Center channel. · Source is a 2/0 (etc. ). · Center set to "OFF" on `Speaker Configuration' menu. · Center level set too low on `Speaker Levels' menu. · Play a known 5. 1-channel recording or select Dolby Pro Logic IIx Music mode. · Correct `Speaker Configuration' or `Speaker Levels' settings. No Dolby Digital/DTS. · Source's digital output is not connected to a T 775 digital input. [. . . ]
