The Auto Multi-Channel Acoustic Calibration 
(MCACC) setup measures the acoustic 
characteristics of your listening area, taking 
into account ambient noise, speaker size and 
distance, 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. 

• The test tones used in the Auto MCACC 

Setup are output at high volume.

• The Auto MCACC Setup will overwrite any 

existing speaker settings you’ve made.

• Before using the Auto MCACC Setup, the 

iPod USB function should not be selected 
as an input source.

• When both the surround back speaker and 

the front height speaker are connected, 
conduct Auto MCACC setup twice: once 
with the Speaker System setting is in 
‘

Surr.Back’ and once with the Speaker 

System setting is in ‘

Height’. (There is no 

need to conduct Auto MCACC Setup every 
time the Speaker System setting is 
changed.)

Switch the TV input so that it connects to the 
receiver.

SETUP MIC jack on the front panel. 
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. Otherwise, place the 
microphone at ear level using a table or a chair.
