Automatically conducting optimum sound tuning (Full Auto
MCACC)
The Full Auto MCACC Setup measures the acoustic characteristics of your listening area, taking into account
ambient noise, speaker connection and speaker size, and tests for both channel delay and channel level. After
you have set up the microphone provided with your system, the receiver uses the information from a series of test
tones to optimize the speaker settings and equalization for your particular room.
By performing the Full Auto MCACC Setup procedure, the frequency-phase characteristics of the connected
speakers are also calibrated.
Once the Full Auto MCACC Setup procedure is completed, the Full Band Phase Control function is automatically
turned on (page 62).
Important
! Make sure the microphone and speakers are not moved during the Full Auto MCACC Setup.
! Using the Full Auto MCACC Setup will overwrite any existing settings for the MCACC preset you select.
! Before using the Full Auto MCACC Setup, the headphones should be disconnected.

nected to the TV's HDMI input terminal by HDMI cable. When connected to the TV with anything other than an
