Again, try to be as quiet as possible while this 
is happening. It may take 1 to 3 minutes.

The settings made in the Auto MCACC Setup 
should give you excellent surround sound from 
your system, but it is also possible to adjust 
these settings manually using the System 
Setup menu (starting on page 42).

If the room environment is not optimal for the 
Auto MCACC Setup (too much background 
noise, echo off the walls, obstacles blocking 
the speakers from the microphone) the final 
settings may be incorrect. Check for household 
appliances (air conditioner, fridge, fan, etc.), 
that may be affecting the environment and 
switch them off if necessary. If there are any 
instructions showing in the front panel display, 
please follow them.

• Some older TVs may interfere with the 

operation of the microphone. If this seems 
to be happening, switch off the TV when 
doing the Auto MCACC Setup.

will end up with different size settings. You can correct the setting manually using the Speaker Setting on page 43.
• The subwoofer distance setting may be farther than the actual distance from the listening position. This setting should be 
accurate (taking delay and room characteristics into account) and generally does not need to be changed.
