Making receiver settings from the Advanced MCACC menu
The Advanced MCACC (Multi Channel ACoustic Calibration) system was developed in Pioneer’s laboratories with
the aim of making it possible for home users to perform adjustments of the same level as in a studio easily and
with high precision. The acoustic characteristics of the listening environment are measured and the frequency
response is calibrated accordingly to allow high precision, automatic analysis and optimal calibration of the
sound field to bring it closer to a studio environment than ever before. Furthermore, while it was previously dif-
ficult to eliminate standing waves, this receiver is equipped with a standing wave control function using a unique
process to perform acoustic analysis and reduce their influence.
This section describes how to calibrate the sound field automatically and fine-adjust the sound field data
manually.
1 Press u STANDBY/ON to switch on the receiver and your TV.
Make sure that the TV’s video input is set to this receiver.
2 Press on the remote control, then press HOME MENU.
A Graphical User Interface (GUI) screen appears on your TV. Use i/j/k/l and ENTER to navigate through the
screens and select menu items. Press RETURN to exit the current menu.
! Press HOME MENU at any time to exit the Home Menu.
3 Select ‘Advanced MCACC’ from the Home Menu, then press ENTER.
4 Select the setting you want to adjust.
! Full Auto MCACC – See Automatically conducting optimum sound tuning (Full Auto MCACC) on page 44 for
a quick and effective automatic surround setup.
! Auto MCACC – See Automatic MCACC (Expert) on page 89 for a more detailed MCACC setup.
! Manual MCACC – Fine-tunes your speaker settings and customizes the Acoustic Calibration EQ (see Manual
MCACC setup on page 91 ).
! Demo – 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.
Automatic MCACC (Expert)
If your setup requires more detailed settings than those provided in Automatically conducting optimum sound
tuning (Full Auto MCACC) on page 44 , you can customize your setup options below. You can calibrate your sys-
tem differently for up to six different MCACC presets, which are useful if you have different listening positions
depending on the type of source (for example, watching movies from a sofa, or playing a video game close to the
TV).
Important
! Make sure the microphone/speakers are not moved during the Auto MCACC Setup.
! The screen saver will automatically appear after five minutes of inactivity.
CAUTION
! The test tones used in the Auto MCACC Setup are output at high volume.
1 Select ‘Auto MCACC’ from the Advanced MCACC menu, then press ENTER.
If the Advanced MCACC screen is not displayed, refer to Making receiver settings from the Advanced MCACC
menu on page 89 .
2 Select the parameters you want to set.
Use i/j to select the item, then use k/l to set.
! Auto MCACC – The default is ALL (recommended), but you can limit the system calibration to only one set-
ting (to save time) if you want.
— When data measurement is taken (after selecting ALL or Keep SP System), the reverb characteristics
data (both before- and after-calibration) that this receiver had been storing will be overwritten.
— When measurement is performed with other than SYMMETRY (after selecting ALL or Keep SP System),
the reverberation characteristics after calibration cannot be predicted, so the graph for the characteristics
after calibration (“After”) cannot be displayed. If you will need to display the graph for the characteristics
after calibration (“After”), take the measurement using the EQ Professional menu in the Manual MCACC
setup (
page 91 ).
— The EQ Pro & S-Wave measurement is also taken when ALL or Keep SP System is selected. See
Acoustic Calibration EQ Professional on page 92 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 73 .
! EQ Type (only available when the Auto MCACC Menu above is EQ Pro & S-Wave) – This determines how the
frequency balance is adjusted.
After a single calibration is performed, each of the following three correction curves can be stored separately
in the MCACC memory.
— SYMMETRY implements symmetric correction for each pair of left and right speakers to flatten the
frequency-amplitude characteristics.
— ALL CH ADJ is a ‘flat’ setting where all the speakers are set individually so no special weighting is given to
any one channel.
— FRONT ALIGN sets all speakers in accordance with the front speaker settings (no equalization is applied
to the front left and right channels).
If you selected ALL or Keep SP System as your Auto MCACC menu, you can specify the MCACC preset
where you want to save the SYMMETRY, ALL CH ADJ and FRONT ALIGN settings.
! THX Speaker (only available when the Auto MCACC Menu above is ALL or Speaker Setting) – Select YES
when using THX speakers (all speakers other than the front speakers are set to SMALL). In other cases, leave
at NO.
! STAND.WAVE Multi-Point (only available when the Auto MCACC 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 sev-
eral seating positions in your listening area. Place the microphone at the reference point indicated on-screen
and note that the last microphone placement will be at your main listening position:
