Use 

/ to select the item, then use / to set.

• Auto MCACC – The default is ALL (recommended), 

but you can limit the system calibration to only one 
setting (to save time) if you want.

1

• EQ Type (only available when the Auto MCACC 

EQ Pro & S-Wave) – This determines 

how the frequency balance is adjusted.

After a single calibration is performed, each of the 
following three correction curves can be stored 
separately in the MCACC memory. SYMMETRY 
implements symmetric correction for each pair of left 
and right speakers to flatten the frequency-amplitude 
characteristics. ALL CH ADJ is a ‘flat’ setting where all 
the speakers are set individually so no special weighting 
is given to any one channel. FRONT ALIGN

2

 sets all 

speakers in accordance with the front speaker settings 
(no equalization is applied to the front left and right 
channels).

• THX Speaker (only available when the Auto MCACC 

ALL or Speaker Setting) – Select YES 

if you are using THX speakers (set all speakers to 
SMALL), otherwise leave it set to NO.

• STAND.WAVE Multi-Point (only available when the 

Auto MCACC Menu above is EQ Pro & S-Wave) – In 
addition to measurements at the listening position, 
you can use two more reference points for which test 
tones will be analyzed for standing waves. This is 
useful if you want to get a balanced ‘flat’ calibration 
for several seating positions in your listening area. 
Place the microphone at the reference point 
indicated on-screen and note that the last 
microphone placement will be at your main listening 
position:

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. If you 
do not have a tripod, use some other object to install the 
microphone.

outputting test tones.
A progress report is displayed on-screen while the 
receiver outputs test tones to determine the speakers 
present in your setup. Try to be as quiet as possible while 

it’s doing this.

• With  error messages (such as Too much ambient 

noise! or Check microphone) select RETRY after 
checking for ambient noise (see Problems when 
using the Auto MCACC Setup on page 39) and 
verifying the mic connection. If there doesn’t seem to 
be a problem, you can simply select GO NEXT and 
continue.

the GUI screen.
The configuration shown on-screen should reflect the 
actual speakers you have.

1 •  When  data  measurement is taken (after selecting ALL or Keep SP System), the reverb characteristics data (both before- and after-

calibration) that this receiver had been storing will be overwritten. If you want to save the reverb characteristics data before measuring, 
connect a USB memory device to this receiver and transfer the data.
• When measurement is taken of data other than SYMMETRY (after selecting ALL or Keep SP System), the data are not measured after the 
correction. If you will need to measure after correction data, take the measurement using the EQ Professional menu in the Manual MCACC 
setup (page 75).
• The EQ Pro & S-Wave measurement is also taken when Keep SP System or EQ Pro & S-Wave is selected. See Acoustic Calibration EQ 
Professional on page 77 for more on this.
• Either effect of Acoustic Calibration EQ Professional and Standing Wave can be switched on and off in the respective MCACC preset. For 
details, see Setting the Audio options on page 59.

2 If you selected ALL or Keep SP System as your Auto MCACC menu, you can specify the MCACC preset where you want to save the 

SYMMETRY, ALL CH ADJ and FRONT ALIGN settings.
