Acoustic Cal EQ
Use this to display the calibration values for the frequency response of the various channels set in the different
MCACC presets. See Acoustic Calibration EQ Adjust on page 102 for more on this.
1 Select ‘Acoustic Cal EQ’ from the MCACC Data Check menu.
2 When ‘Ch’ is highlighted, use i/j to select the channel.
The calibration value for the frequency response of the selected channel stored at the selected MCACC preset
and its graph are displayed.
3 Press k to highlight ‘MCACC’, then use i/j to select the MCACC preset you want to
check.
Group Delay
Use this to display the calibrated speaker group delay results. See Better sound using Phase Control on page
73 for more on this.
1 Select ‘Group Delay’ from the MCACC Data Check menu.
2 When ‘Channel’ is highlighted, use k/l to select the channel you want to check.
The result of group delay calibration for the selected channel is displayed.
When measurements have been performed with Full Auto MCACC selected at Advanced MCACC or with ALL
or Full Band Phase Ctrl selected when Auto MCACC is selected, the graph before group delay calibration is also
displayed.
When After is selected at Calibration, the group delay after calibration is displayed. Compared to when Before
is selected, with After there is less difference in the delay between frequency bands and the group delay between
the different channels is uniform, allowing you to check the full band phase control effect.
No Data is displayed if the selected group delay has not been measured.
Data Management
This system allows you to store up to six MCACC presets, allowing you to calibrate your system for different listen-
ing positions (or frequency adjustments for the same listening position). 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 copy from one preset to another, name presets for easier identification and clear any
ones you don’t need.
! This can be done in Automatically conducting optimum sound tuning (Full Auto MCACC) on page 57 or
Automatic MCACC (Expert) on page 99 , either of which you should have already completed.
1 Select ‘Data Management’ from the MCACC PRO (VSX-1130/VSX-930)/Advanced MCACC
(VSX-830) menu, then press ENTER.
2 Select the setting you want to adjust.
! Memory Rename – Name your MCACC presets for easy identification (see Renaming MCACC presets on
page 104 ).
! MCACC Memory Copy – Copy settings from one MCACC preset to another (see Copying MCACC preset data
on page 104 ).
! MCACC Memory Clear – Clear any MCACC presets that you don’t want (see Clearing MCACC presets on
page 104 ).
Renaming MCACC presets
If you have several different MCACC presets that you’re using, you may want to rename them for easier
identification.
1 Select ‘Memory Rename’ from the Data Management setup menu.
2 Select the MCACC preset you want to rename, then select an appropriate preset name.
Use i/j to select the preset, then k/l to select a preset name.
3 Repeat for as many MCACC presets as necessary, then press RETURN when you’re finished.
You will return to the Data Management setup menu.
Copying MCACC preset data
If you want to manually adjust the Acoustic Calibration EQ (see Manual MCACC setup on page 101 ), we recom-
mend copying your current settings to an unused MCACC preset. Instead of just a flat EQ curve, this will give you
a reference point from which to start.
! The settings made in Automatically conducting optimum sound tuning (Full Auto MCACC) on page 57 or
Automatic MCACC (Expert) on page 99 .
1 Select ‘MCACC Memory Copy’ from the Data Management setup menu.
2 Select the setting you want to copy.
! All Data – Copies all the settings of the selected MCACC preset memory.
! Level & Distance – Copies only the channel level and speaker distance settings of the selected MCACC pre-
set memory.
3 Select the MCACC preset you’ll be copying the settings ‘From’, then specify where you
want to copy them ‘To’.
Make sure you don’t overwrite an MCACC preset you’re currently using (this can’t be undone).
4 Select ‘OK’ to confirm and copy the settings.
When MCACC Memory Copy? is displayed, select YES. If NO is selected, the memory is not copied.
Completed! shows in the GUI screen to confirm the MCACC preset has been copied, then you automatically
return to the Data Management setup menu.
Clearing MCACC presets
If you are no longer using one of the MCACC presets stored in memory, you can choose to clear the calibration
settings of that preset.
1 Select ‘MCACC Memory Clear’ from the Data Management setup menu.
2 Select the MCACC preset you want to clear.
Make sure you don’t clear an MCACC preset you’re currently using (this can’t be undone).
3 Select ‘OK’ to confirm and clear the preset.
When MCACC Memory Clear? is displayed, select YES. If NO is selected, the memory is not cleared.
Completed! shows in the GUI screen to confirm the MCACC preset has been cleared, then you automatically
return to the Data Management setup menu.
