The 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.

Make sure you do this before moving on to Playing a 
source on page 45.

• Make  sure the microphone and speakers are not 

moved during the Auto MCACC Setup.

• Using the Auto MCACC Setup will overwrite any 

existing settings for the MCACC preset you select.

• Before using the Auto MCACC Setup, the 

headphones should be disconnected and the iPod/
USB, XM or SIRIUS Radio function should not be 
selected as an input function.

• The test tones used in the Auto MCACC Setup are 

output at high volume.

 

 

Use 

 RECEIVER to switch on.

• Push  down  on  the  PUSH OPEN tab to access the 

MCACC SETUP MIC jack.

Make sure there are no obstacles between the speakers 
and the microphone.

If you have a tripod, use it to place the microphone 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.
