•Custom Menu – The default is ALL (recommended), but you can limit the system calibration to only one setting (to save time) if you want.6 The available options are ALL, Keep SP SYSTEM,7 Speaker Setting, Channel Level, Speaker Distance and EQ Pro. & S-Wave.

•EQ Type (only available when the Custom Menu above is 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 (default) implements symmetric correction for each pair of left and right speakers to flatten the frequency amplitude characteristics. ALL CH ADJUST is a ‘flat’ setting where all the speakers are set individually so no special

weighting is given to any one channel. FRONT ALIGN8 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 Custom Menu above is 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 Custom 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.9 Place the microphone at the reference point indicated on-screen and note the last microphone placement will be at your main listening position:

position

When you’re finished settings the options, press RETURN to go back to the Auto MCACC main setup.

Note

1Except in cases where you are only adjusting one parameter (i.e. channel level) from the CUSTOM setup screen (step 2).

2If you are planning on bi-amping your front speakers, or setting up a separate speaker system in another room, read through Surround back speaker setting on page 40 and make sure to connect your speakers as necessary before continuing to step 3.

3The six MCACC presets are used for storing surround sound settings for different listening positions. Simply choose an unused preset for now (you can rename it later in Data Management on page 46).

4Note that correction curves are saved only when set to SYMMETRY. Select CUSTOM to save other correction curves (such as ALL CH ADJUST and

FRONT ALIGN).

5Select DEMO, and then press ENTER to activate the demo mode of Auto MCACC. In the demo mode, no settings are saved and no errors occur. When the speakers are connected to this receiver, the test tone is output repeatedly. Press RETURN to cancel the test tone.

6• The EQ Pro. & S-Wavemeasurement is also taken when ALL is selected. See Acoustic Calibration EQ Professional on page 43 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 68.

•The FULL BAND PHASE CTRL measurement is also taken when ALL is selected. See Full Band Phase Control on page 45.

7The Keep SP SYSTEM option allows you to calibrate your system while leaving your current speaker setting (page 48) unchanged.

8If you selected ALL as your Custom Menu, you can specify the MCACC preset where you want to save the ALL CH ADJUST and FRONT ALIGN settings.

9Switch the Multi-Pointsetting OFF if you only use one listening position.
