Manually calibrating your 
listening area (MCACC)

You can use the Multi-Channel Acoustic Cali-
bration (MCACC) system to fine tune your 
speaker levels and channel delay. These are 
calibrated according to the distance from 
your left front speaker to the listening posi-
tion. You will hear a series of test tones that 
will allow you to set the speaker levels and 
channel delay to your liking. The advantage of 
doing this is that you can achieve an overall 
balance defined by the front speakers (the 
main speakers for home theater).

• You must complete the Speaker setting on 

• These test tones can be loud, so take care 

that there is no one in the room who will 
be startled by the noise.

The MCACC system uses the left front 
speaker as a reference point to calibrate the 
speaker level and channel delay.

The front left speaker tone and the target 
speaker (the one that you’re trying to adjust) 
tone will sound in turns, so you can judge 
which needs to be louder.

 and  to adjust each channel 

level in turn, pressing ENTER to go to the 
next channel when you’re done. 
The test tone is output in the following order 
(depending on the speaker setting):

 and  to adjust the delay for 

each channel in turn, pressing ENTER to go 
to the next channel when you’re done. 
Listen to the reference channel and use it to 
measure the target channel. Stand facing the 
two speakers with your arms outstretched 
pointing at each speaker. Try to make the two 
tones sound as if they are arriving simulta-
neously at a position slightly in front of you 
and between your arm span.
