USING THE T 775 – SETUP MENU

Measurement is the first step

The sound at each listening position (up to 8 positions) is calibrated using the same microphone used during the setup phase.

A special test tone is sent to each speaker and the data is memorized by the T 775. The duration of calibration may take some time depending on the number of speakers as well as the number of measuring points. 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. A notice screen is correspondingly displayed. 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

The test tone emitted during measurement is loud. This maybe bothersome for you and may affect your other household members as well, and even your neighbor.

Next a Target Curve must be chosen

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.

Corrected Room Response

Flat EQ is a third option, but not one that we recommend for listening (it is useful for verifying system performance when using external instrumentation).

Select the Target Curve you find to be most satisfactory by pressing the Audyssey key of the remote. The MultEQ XT corrected response can also be bypassed if you wish.

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.

Note

During manual setting of your speakers, previously calibrated Audyssey settings could be retrieved by re-adjusting back the altered configurations as highlighted by an asterisk.
