Again, try to be as quiet as possible while this is happening. It may take 3 to 7 minutes.

•If you selected a STAND.WAVE Multi-Pointsetup (in step 2), you will be asked to place the mic at the 2nd and 3rd reference points before finally placing it at your main listening position.

9The Auto MCACC Setup procedure is completed and the Advanced MCACC menu reappears automatically. 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

Manual MCACC setup menu (starting below) or Manual SP Setup menu (starting on page 84).1

You can also choose to view the settings by selecting individual parameters from the MCACC Data Check screen:

•Speaker Setting – The size and number of speakers you’ve connected (see page 85 for more on this)

•Channel Level – The overall balance of your speaker system (see page 75 or 86 for more on this)

•Speaker Distance – The distance of your speakers

from the listening position (see page 75 or 87 for more on this)2

•Standing Wave – Filter settings to control lower ‘boomy’ frequencies (see page 76 for more on this)

•Acoustic Cal EQ – Adjustments to the frequency balance of your speaker system based on the acoustic characteristics of your room (see page 77 for more on this)

•Output PC – The data transfer mode with the connected computer is set. The graphs of the reverb characteristics before and after calibration and the various MCACC parameters can be checked (see Output PC on page 81 for more on this).

Manual MCACC setup

You can use the settings in the Manual MCACC setup menu to make detailed adjustments when you’re more familiar with the system. Before making these settings, you should have already completed Automatically setting up for surround sound (Auto MCACC) on page 39.

You only need to make these settings once (unless you change the placement of your current speaker system or add new speakers).

CAUTION

•The test tones used in the Manual MCACC setup are output at high volume.

Important

•You will need to first specify the MCACC preset you want to adjust by pressing MCACC before pressing HOME MENU (step 2 in Making receiver settings from the Advanced MCACC menu on page 71).

•For some of the settings below, you’ll have to connect the setup microphone to the front panel and place it about ear level at your normal listening position.

Press HOME MENU to display the HOME MENU before you connect the microphone to this receiver. If the microphone is connected while the HOME MENU is not being displayed, the display will change to the Full Auto MCACC under Advanced MCACC.

•See Problems when using the Auto MCACC Setup on page 40 for notes regarding high background noise levels and other possible interference.

•If you’re using a subwoofer, switch it on and turn up the volume to the middle position.

Note

1• Depending on the characteristics of your room, sometimes identical speakers with cone sizes of around 12 cm will end up with different size settings. You can correct the setting manually using the Manual speaker setup on page 84.

•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.

•If Auto MCACC Setup measurement results are incorrect due to the interaction of the speakers and viewing environment, we recommend adjusting the settings manually.

2Since the distance measurements have been set according to the sound characteristics of your speakers, there are cases where (for optimal surround sound) the actual distance may differ from the speaker distance setting.
