Data Management

This system allows you to store up to six MCACC presets, allowing you to calibrate your system for different listening positions (or frequency adjustments for the

same listening position).3 This is useful for alternate settings to match the kind of source you’re listening to and where you’re sitting (for example, watching movies from a sofa, or playing a video game close to the TV).

From this menu you can check your current settings, copy from one preset to another, name presets for easier identification and clear any ones you don’t need.

1Select ‘Data Management’ from the System Setup menu.

See Making receiver settings from the System Setup menu above if you’re not already at this screen.

•MCACC Memory Copy – Copy settings from one MCACC preset to another (see Copying MCACC preset data below).

•MCACC Memory Clear – Clear any MCACC presets that you don’t want (see Clearing MCACC presets below).

•Output PC – See Connecting a PC for Advanced MCACC output on page 61 for more on this.

Checking MCACC preset data

After you have completed Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 8 or Automatic MCACC (Expert) on page 37, you can check your calibrated settings using the on-screen display.

Note

1When your PC is connected to this receiver, the original characteristics of group delay of the speakers calibrated and the corrected characteristics of group delay can be displayed in 3-dimension on your PC.

2The subwoofer is excluded from correction.The super tweeter in the super high-frequency range is excluded from correction. Also, speakers theoretically unaffected by group delay (full-range speakers, for instance) are excluded from correction. Because calibration involves the spatial characteristics, you may not get the same results after you perform calibration again depending on your audiovisual environment and your speaker system.

3This can be done in Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 8 or Automatic MCACC (Expert) on page 37, either of which you should have already completed.
