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 755. 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.
NOTES
• The test tone emitted during measurement is loud. This maybe bothersome for you and may affect
as well your other household members and even your neighbor.
• The mention of "Back Right" and "Back Left" refer to your external amplifier's corresponding "Back
Right" and "Back Left" speakers (if any) as interfaced with the T 755. The Audio PRE- OUT makes it
possible to use the T 755 as a pre-amplifier to external power amplifiers for some or all channels.
It is recommended that you take full advantage of the T 755'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.

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 "Back" setup item to "Off".
