•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.8 Place the microphone at the reference point indicated on-screen and note the last microphone placement will be at your main listening position:

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 ALIGN7 sets all speakers in accordance with the front speaker settings (no equalization is applied to the front left and right channels).

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.

4Follow the instructions on-screen.

•Make sure the microphone is connected.

•If you’re using a subwoofer, it is automatically detected every time you switch on the system. Make sure it is on and the volume is turned up.

Note

1If 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 41 and make sure to connect your speakers as necessary before continuing to step 3.

2The 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).

3Note 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).

4Select 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.

5• The EQ Pro. & S-Wavemeasurement is also taken when ALL is selected. See Acoustic Calibration EQ Professional on page 44 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 69.

6The Keep SP System option allows you to calibrate your system while leaving your current speaker setting (page 47) unchanged.

7If 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.

8Switch the Multi-Pointsetting NO if you only use one listening position.
