This section describes how to calibrate the frequency-
phase characteristics of the speakers only. Once you
have performed calibration with Auto MCACC set as a
default setting or with
CUSTOM set to ALL, the Full Band
Phase Control calibration is already done (In this case,
the previous settings are overwritten if you perform
calibration again as described here).
1 Select ‘FULL BAND PHASE CTRL’ from the System
Setup menu.
See
Making amplifier settings from the System Setup
menu on page 40 if you’re not already at this screen.
2 Select an option and press ENTER.
• Measurement – Calibrates and corrects the
frequency-phase characteristics of each speaker.
• Group Delay View – The original characteristics of
group delay of the speakers calibrated and the
targeted characteristics can be displayed
graphically.
3 If you selected ‘Measurement’, press ENTER.
1
When the Full Band Phase Control measurement is
finished, you can select
Group Delay View to see the
results on-screen.
4 If you selected ‘Group Delay View’, you can check
the graph showing the group delay characteristics.
Press RETURN, then you’re done. 2
This appears according to the setting you chose in
Measurement (step 2 above). Use
/ to select the
channel you want to check. 3
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).
4
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.
1 Select ‘Data Management’ from the System Setup
menu.
See
Making amplifier settings from the System Setup
menu on page 40 if you’re not already at this screen.
2 Select the setting you want to adjust.
• MCACC Data Check – Check the settings for any of
your MCACC presets using the on-screen display
(see
Checking MCACC preset data on page 51).
• Memory Rename – Name your MCACC presets for
easy identification (see
Renaming MCACC presets on
page 51).
• MCACC Memory Copy – Copy settings from one
MCACC preset to another (see
Copying MCACC
preset data on page 51).
• MCACC Memory Clear – Clear any MCACC presets
that you don’t want (see
Clearing MCACC presets on
page 51).
• Output PC – See Connecting a PC for Advanced
MCACC output on page 69 for more on this.
Note
1 When Measurement is selected and set and speaker phase disturbance is corrected, the Full Band Phase Control function automatically turns on.
2 When your PC is connected to this amplifier, 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.

3 The 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.
4 This can be done in
Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 11 or Automatic MCACC (Expert) on page 40,
either of which you should have already completed.
