About the Advanced MCACC Application (Continued)
Things you can accomplish with this application
1. Advanced EQ Setup, which you can do with the receiver (see page 84 of the receiver’s Operating
Instructions), allows you to choose the optimum time period for auto EQ setup. You can use this
application’s reverberation characteristics (Reverb) as a guide in choosing the best time period for
your room.
For details, see Deciding the time period for Advanced EQ Setup calibration (page 19).
2. Skewed reverb frequency characteristics in your listening room can prevent you from enjoying an
accurate sound field. The graphs displayed by this application are a powerful tool because they
allow you to check these reverb frequency characteristics at a glance. You can also check the
effectiveness of steps that you take to improve the acoustics of your listening room, for example,
installing sound absorbent material.
For details, see Checking steps to improve your room’s reverb characteristics (page 21).
3. The reverb characteristics after calibration can be displayed. This lets you to check the EQ effects of
the Advanced MCACC measurements you have made.
For details, see About the display of the reverb characteristics graphs before and after calibration
(page 23).
4. The MCACC parameter display (Parameters) allows you to display on the computer all the
parameters (measurement values) stored in the receiver’s MCACC memories.
For details, see Display of the MCACC parameters (page 25).

How to Interpret the Graphs
As indicated in Things you can accomplish with this application (page 3), the reverb characteristics graph
can be used as reference when determining the calibration time position with the receiver’s “Advanced EQ
Setup” function. It is also a valuable means for checking the effect of measures taken to improve the
acoustics of the room. The display can be switched between the reverb characteristics graphs before and
after calibration. For details, see About the display of the reverb characteristics graphs before and after
calibration (page 23)
.
How to interpret reverb graphs (Reverb)
The graphs show changes in microphone input level along a time axis, beginning from a state of quiet at
time 0, when test tones begin to be output, and continuing while a constant level of sound is output from the
speakers.
• If there is absolutely no reverberation in your room, the graph will look like figure A below.
• If there is reverberation, the graph will show a gradual accumulation of acoustic power, as shown in figure B.
Note
• Due to an effect known as “group delay”, lower frequencies may take longer to be generated than higher
frequencies (this is most obvious when comparing the frequencies around 0 ms).
• If a graph extends beyond the display range, or almost fills it, you can change the display by using the Z
(Zoom) control on the graph adjustment bar, adjusting the display range of the Level [dB] scale so that the
whole graph is visible.
• Since channel level and speaker distance settings are displayed in the graphical output, it is best to make
sure these settings (made in the Auto MCACC “ALL” or “Channel Level” setup) are adjusted properly
before reverb measurement.
• Even in cases where there is a great difference in the output levels of different frequencies (the frequency
characteristics of the room are poor), the frequency characteristics of individual channels can be set
closer to flat using the “SYMMETRY” or “ALL CH ADJ” calibration settings in the receiver’s “Auto MCACC”
function. (For details, see page 78 of the receiver’s Operating Instructions.)
• It is usually not possible to calculate the equalization values employed by the receiver’s Acoustic Cal EQ
function simply by viewing the graphs displayed on your PC. (This is because the automatic adjustments
made by Acoustic Cal EQ function take account of factors such as equalization band interference and
analytical filter characteristics, to achieve the optimum characteristic profile.)
• There may be differences on the reverb characteristics graphs after measurements with the Full Auto
MCACC function as compared to after measurements with the Reverb Measurement function (Manual
MCACC “EQ Professional”) due to the standing wave control setting. With Full Auto MCACC, the
reverberations are measured with standing wave controlled, so the reverb characteristics graph does not
reflect the influence of the standing waves. By contrast, with Reverb Measurement, the reverberations are
measured without standing wave control, so you can check the reverb characteristics including the
influence of the standing waves. If you want to check the acoustics of the room (with the standing waves),
we recommend using Reverb Measurement.

Deciding the time period for Advanced EQ Setup calibration
With conventional MCACC EQ calibration, the microphone input’s data acquisition time was fixed at
between 80 and 160 [ms] (red part of Figure 1). By contrast, with the receiver’s Advanced EQ Setup function
allowing more professional equalization, the customer can select individual points between 0 and 80 [ms]
(with a 20 ms width) (blue part of Figure 1).
Note
You can specify the time period setting using the “Advanced EQ Setup” in the “EQ Professional” sub-menu
(in the “Manual MCACC” menu). This setting is not required if you’re satisfied with the results of the “Full
Auto MCACC” setup (For details, see page 84 of the receiver’s Operating Instructions).

Time (in ms)
To decide the time period for Advanced EQ Setup calibration, view the graphs of the measured reverb
characteristics, and refer to the following three patterns.
Pattern 1: Different reverb characteristics for high and low frequencies
In rooms with reverb characteristics like those shown in Figure 2, lower frequencies often seem overly
reverberant compared to higher frequencies (i.e. the room sounds ‘boomy’). With conventional MCACC EQ
calibration, data between 80 and 160 [ms] (red part of Figure 2) was acquired, so the low frequency volume
was deemed high and the high frequency volume deemed low, and the equalization curve was calibrated
with the high frequencies somewhat boosted. However, for the characteristics of the sound reaching the ear
directly within about 40 ms, there is enough volume that there is no real need to boost the high frequencies,
so with equalization using the conventional MCACC EQ calibration the high frequencies sometimes
sounded too strong. Therefore, the Acoustic Cal EQ may result in a room where high frequencies sound
shrill. In cases like this, setting the time period for Advanced EQ Setup to 30 to 50 msec (the blue area
in Figure 2) to adjust for sounds coming directly from the speakers can flatten the frequency response
for direct sounds (including initial reflections) and give a better-balanced sound field.

How to Interpret the Graphs (Continued)
Pattern 2: Different reverb characteristics for different channels
If the reverb characteristics differ for the different channels as shown in Figure 3, equalization using the
conventional Acoustic Cal EQ acquired data between 80 and 160 [ms] (red part of Figure 3), so equalization
was performed to gradually equalize the tone of the different channels for 80 ms from the time the sound
was emitted from the speakers and after (it was not possible to equalize the response of the direct sound).
However, the sense of placement and movement of the acoustic image and the unity of the sound from the
different speakers is influenced not by the reverberations but by the direct sound from the speakers
(including the early reflected sound). In cases like this, you should use Advanced EQ Setup and set the
time period to 30 to 50 msec (the blue area in Figure 3). This allows the characteristics of direct sounds
to be balanced for each channel, giving an ideal sound field with good acoustic positioning and
movement.

Time (in ms)
Pattern 3: Similar reverb characteristics for high and low frequencies and
all channels
As shown in Figure 4, when the reverb characteristics for all channels are similar across all frequencies,
your sound experience will probably not be adversely affected by reverberation. We recommend
calibrating with a time of about 60 to 80 [ms] (green part of Figure 4) specified at Advanced EQ Setup.
This produces a total calibration for both direct sounds and reverberations, resulting in an ideal sound
field.

Note
• If you are not sure which time period to specify in Advanced EQ Setup, start by trying 30 to 50 msec. If the
graphs show an unusual reverb curve for a specific frequency, the cause may be some accidental
variation. Instead of selecting 30 to 50 msec, try another time period.
• Another good method is to try various time periods in Advanced EQ Setup and select the one which
sounds the best.
• Time period settings cannot be made on the PC. They can only be made on the GUI screen output from
the receiver’s video outputs, using the receiver’s Advanced EQ Setup function.

Checking steps to improve your room’s reverb characteristics
The reverb characteristics of your listening room graphs are evident from the graphs. For your reference, the
following four examples explain how different types of rooms appear in the graphs.
Case 1: Graph rises to right across all frequencies
This is probably a room with a good deal of reverberation. If possible, we recommend that you try installing
some sound absorbent material to create a deader acoustic space according to your preference.
Case 2: Specific channel shows unusual reverb characteristics
There is probably some object near the speaker which affects sound reproduction. If possible, we
recommend that you try to reduce the influence of that object.
Continue

How to Interpret the Graphs (Continued)
Case 3: Specific frequency shows unusual reverb characteristics
There is probably something in the room that affects the reproduction of that frequency. If possible, try to
find an arrangement that reduces the effect.
Case 4: A specific channel is slow to start
This can happen when a speaker is unstable. If possible, we recommend that you try to stabilize the
speaker stand, to bring the characteristics of that channel into line with the other channels.
Note
In all of these cases, when the “Full Auto MCACC” operation is performed, the calibration time position is
selected automatically in consideration of the room’s characteristics so that the optimum sound field can be
achieved. (See page 41 of the receiver’s Operating Instructions.)
When measurements are made with the “Auto MCACC” function, automatic calibration taking the
reverberations into consideration is only performed when “ALL”, “Keep SP System” or “EQ Pro & S-Wave” is
selected at “Auto MCACC”. (See page 78 of the receiver’s Operating Instructions.)

About the display of the reverb characteristics graphs before
and after calibration
By comparing the reverberation characteristics graphs before and after calibration, you can check how the
reverb characteristics have been calibrated. Select “Before” to display the graph of the reverberation
characteristics before EQ calibration, “After” to display the graph of the reverb characteristics after EQ
calibration. If you want to check the actually measured reverb characteristics after EQ calibration, see
Displaying the reverb characteristics after EQ calibration (actually measured values) (page 24).
Graph of reverb characteristics before calibration
You can see that the reverb characteristics of the various frequencies of the different channels are uneven.
Graph of reverb characteristics after calibration
You can see that compared to the graph before calibration the lines for the individual frequencies move in
parallel by the amount of equalization and converge at the specified point on the time axis.
Note
• The graphs displaying reverb measurements both before and after calibration are displayed in 2-D for
comparison purposes.

About the types of displays of the graph for the reverb
characteristics after EQ calibration
For “SYMMETRY” or “FRONT ALIGN”
• The display type is set to “Pair Ch” (page 13). For reasons of the properties of the different EQ curves,
when the “Each Ch” display type is set, the reverb characteristics for the different channels do not line up
properly.
• The reverb characteristics prior to calibration are displayed in the “Each Ch” mode, so if you want to
compare the characteristics before and after calibration, set the display type prior to calibration to “Pair
Ch”. This way the number of channels before and after calibration are the same, allowing you to compare.
For “ALL CH ADJ”
• The display type is set to “Each Ch” (page 13). For reasons of the properties of the EQ curves, when the
“Pair Ch” display type is set, the reverb characteristics for the different pairs of channels do not line up
properly.
• Since the “Each Ch” display type is set both before and after calibration, the graphs can be compared as
such.
Displaying the reverb characteristics after EQ calibration (actually
measured values)
The graphs for before and after calibration can be displayed at the screen displaying the graphs of the
reverberation characteristics after Full Auto MCACC measurements, but note that the graph displayed here
for the characteristics after calibration is a prediction of the reverb characteristics after MCACC calibration.
If you want to check the graph of the actually measured reverberation characteristics after MCACC
calibration (not the prediction), you must re-measure the reverb characteristics after calibration. To do so,
follow the procedure described below.
1 Connect the receiver to your PC with an RS-232C cable.
If the “Full Auto MCACC” operation has never been performed, conduct the “Full Auto MCACC”
operation here.
(See page 41 of the receiver’s Operating Instructions.)
2 Select the “EQ Professional” option for “Manual MCACC”, and perform with
“Reverb Measurement” set to “EQ ON”.
(See page 84 of the receiver’s Operating Instructions.)
Measure the room’s reverb characteristics after equalization with the microphone at the same position as
when the “Full Auto MCACC” operation was performed. The measurements are performed with the EQ
values stored in the MCACC memory selected on the receiver, so before measuring the reverb
characteristics, select the MCACC memory to be measured after equalization.
3 Receive and save the data by selecting “Output PC” from “MCACC Data Check”.
You can display the graph of the reverberation characteristics actually measured after EQ calibration by
displaying the Reverb graph and selecting “After”.

The application is unstable, or does not work normally
Cause 1:
If your PC does not meet the requirements for using this application, the
application can be unstable, very slow, or freeze up.
Check to be sure that your PC meets the requirements for using this application. (See page 2.) You
cannot use this application unless your PC meets all of the requirements.
Cause 2:
Even if the required conditions for the computer environment are met, if many
files are opened in the application and all are displayed with the MCACC
Parameters option, an error message may appear due to lack of computer
memory.
If an error message like the one shown below appears, either close some of the opened files, or quit the
application itself then restart it. If you want to compare many files, we recommend printing them out
using the Print function and comparing them on paper.
Not enough storage is available to process this command.
Advanced MCACC cannot be installed
Cause 1:
An error message may appear if there are not enough system resources
available.
If an error message like the one shown below appears, re-start the PC, then start the installer
(PioneerAdvancedMCACC_e_ver_*_*.exe) with no other applications active.
The InstallShield Engine (iKernel.exe) could not be installed.
The system cannot read from the specified device.
Cause 2:
Installation of Advanced MCACC may fail because of incompatibilities with other
applications.
Try the following, in the order indicated.
1) If there are any other applications active, exit the other applications and try starting the installer
(PioneerAdvancedMCACC_e_ver_*_*.exe) again.
2) If that does not work, try restarting your PC, and starting the installer
(PioneerAdvancedMCACC_e_ver_*_*.exe) with no other applications active.

Troubleshooting (Continued)
Cannot send measurement data to PC
Cause 1:
Random transmission errors sometimes occur.
Even if an error occurred on your first attempt, try sending the data again. Sometimes the transmission
succeeds when you try again.
Cause 2:
Messages like the following may appear if a transmission error occurs.
Timeout occurred.
Command error occurred. Please try again.
Send failed.
Try the following, in the order indicated.
1) In the GUI screen of the receiver, check that “Start the MCACC application on your PC” is displayed.
(This message indicates that the receiver is ready to send data to the PC.)
2) Check that the RS-232C cable is properly connected. (Be sure to switch off all components and
disconnect their power cord from the power outlets before changing any cable connections.)
3) Exit any other active applications.
4) Check the COM port number.
5) Check the type of RS-232C cable to use is correct (page 7).
6) Restart the Advanced MCACC application.
7) Restart your PC.
Cause 3:
The following message may appear and the data transmission may be not
available.
Cannot open the serial port (COM*).
Refer to the operation manual for PC or the application software using the COM port, and make the
connecting COM port available for transmission.

Troubleshooting (Continued)
Advanced MCACC cannot be updated
Cause 1:
An error message may appear if there are not enough system resources
available.
If an error message appears (like the one explained above in Cause 1) of Advanced MCACC cannot be
installed (page 31), restart your PC and start the installer (PioneerAdvancedMCACC_e_ver_*_*.exe) with
no other applications active.
Cause 2:
Updating of Advanced MCACC may fail because of incompatibilities with other
applications.
Try the following, in the order indicated.
1) If there are any other applications active, exit the other applications and try starting the installer
(PioneerAdvancedMCACC_e_ver_*_*.exe) again.
2) If that does not work, try restarting your PC, and starting the installer
(PioneerAdvancedMCACC_e_ver_*_*.exe) with no other applications active.
Reverb characteristics graph cannot be printed
Cause:
It is not possible to print reverb characteristics graphs displayed in the “ALL”
mode.
ALL display
Print after selecting an individual channel or frequency graph.
Some functions in application operation cannot be used
Cause:
You may not properly use the application software not corresponding to your
receiver.
Check the model number of your receiver and use the application software corresponding to it.

Troubleshooting (Continued)
The receiver causes a malfunction when it is connected to the PC with an RS-232C
cable
Cause:
When the receiver is connected to your PC with an RS-232C cable, the power of
the receiver may be automatically switched on when you operate the PC.
Unplug the cable when not in use.
EQ response in the graph (following calibration) does not appear flat
Cause 1:
The slope of the graph indicates the reverb characteristics. The reverb
characteristics of the room itself cannot be corrected by equalization alone, so
the angle of the graphs’ slope is the same before and after calibration.
Through calibration, the graphs for the different frequencies move horizontally by the amount of the
equalization. For the results of calibration, you can check that the graphs line up at a specific point on
the time axis.
The reverb characteristics themselves (the shape of the graph) do not change unless the listening
environment is improved.
(See pages 18 to 20.)
Cause 2:
For various reasons, the frequency characteristic graphs may not become flat
even when equalization is performed with the “SYMMETRY” or “ALL CH ADJ”
functions.
With MCACC, calibration is performed automatically to achieve the optimum sound quality, but without
any unreasonable calibration.
Adjustments made with the “Manual MCACC” setup do not change the graph
Cause:
Despite level adjustments being made, the filters used for analysis may not
display these adjustments in the graphical output.
However, these adjustments are taken this into account by the filters dedicated to overall system
calibration.
Lower frequencies do not seem to have been calibrated for SMALL speakers
Cause:
Low frequency calibration with the equalizer is not performed for speakers that
are set to “SMALL”, but the reverb characteristics display shows the pure
characteristics of the sound output from the speakers, so it indicates the
characteristics with no low frequency calibration.
With MCACC, optimum calibration is performed in function of the speakers’ sound reproduction
capacities, so there is no problem for low frequency calibration of speakers that are set to “SMALL”.
