Basic Setup

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 sys-
tem, the receiver uses the information from a
series of test tones to optimize the speaker set-
tings 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 func-
tion is automatically turned on.
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.
CAUTION
! The test tones used in the Full Auto MCACC
Setup are output at high volume.

Make sure there are no obstacles between the
speakers and the microphone.
If you have a tripod, use it to place the micro-
phone so that it's about ear level at your
normal listening position. If you do not have
a tripod, use some other object to install the
microphone.
Install the microphone on a stable floor.
Placing the microphone on any of the following
surfaces may make accurate measurement
impossible:
! Sofas or other soft surfaces.
! High places such as tabletops and sofa tops.
