MEASUREMENT IS THE FIRST STEP
Connect the Audyssey microphone jack into the front panel's MP/MIC input
and the Audyssey Setup wizard will guide you through a simple step-by-
step configuration.
The sound at your main listening position is setup using the supplied Audyssey
microphone. A special test tone is sent to each speaker and the data is
memorized by the T 758. The duration of setup may take some time depending
on the number of speakers. After the measurements, Audyssey calculates the
ideal system response for your particular room and speaker setup.
If some inconsistencies or discrepancies are detected during the Audyssey
setup, 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
setup 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. If you cannot
withstand the test tone level, it is advisable that you stay away from the
room or location where the speakers are being calibrated.
USING THE T 758 – SETUP MENU
It is recommended that you take full advantage of the T 758's Audyssey
Setup feature for your speaker setup. However, if you desire to setup
your speakers manually or if you already had run Audyssey Setup 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.
