Displays 3D graphs of the reverberation frequency characteristics of your room. You can choose to see these measurements both with and without the equalization performed by this receiver (before and after calibration). [. . . ] : Displayed in three dimensions. (Reverb display only) The reverb characteristics graph display type can be changed. The graph for the listening environment's reverb characteristics (before calibration) is displayed with the "Each Ch" mode, allowing you to check the reverb characteristics for the individual channels. Pair Ch: Composite reverb characteristics for the left and right pairs of the "Front", "Surround" and "Surr Back" channels are displayed. Use the "Pair Ch" mode to display the graphs for the reverb characteristics after calibration. To finish, reselect and uncheck the box. Continue 13 Application Operations (Continued) Window Cascade Tile (Reverb display only) Minimize Arrange Cascades files. a Tiles files. a Minimizes the window. Help Version Info Displays the version of the application. 2 Display item selection tab A graph for the selected item or the MCACC parameter list is displayed. 3 Level [dB] The level axis. 4 Time [msec] The time axis. 5 Channel memo (only available when the channels are displayed on the reverb characteristics graph) Allows you to record a short memo about each channel. 6 Date and time Display the date and time when the measurement data was transferred to the PC. 7 Channel and frequency switch buttons Ch: Selects channel display mode (frequencies are displayed along graph depth axes). Data received at one time is saved in one file. 1 To save measure data, choose "Save" from the "File" menu. If you have data that has already been saved and want to save it under a new name, choose "Save As". 2 Check the save location, assign a file name, then click "Save". The data is saved in a CSV format file (the file extension is ". csv"). When you are finished saving data, you should (using the receiver controls) press "RETURN" to exit the Reverb Output PC screen. (See page 70 in the receiver's Operating Instructions. ) Note The CSV format file is often used to transfer data to applications such as databases and spreadsheets. You can use these applications to view the numeric values in your measurement data. However, if you use another application to edit the data and then save the file, the Advanced MCACC application may be unable to open the file. Continue 16 Application Operations (Continued) Opening data files You can open and display two or more data files to compare the data in the files. 1 Select "Open" from the "File" menu in the menu bar. 2 Select a file to display and click "Open". The previously saved measurement data is displayed. Exiting the application 1 Select "Exit" from the "File" menu. The application closes. 17 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. 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. Figure 4 Level (dB) Time period point to be selected Front left low frequencies Front right low frequencies Front left high frequencies Front right high frequencies Time (in ms) 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. · Another good method is to try various time periods in Advanced EQ Setup and select the one which sounds the best. They can only be made on the on-screen display of the receiver, using the receiver's Advanced EQ Setup function. Continue 20 How to Interpret the Graphs (Continued) 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 21 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. [. . . ] Note The application may not operate properly if two versions of it are installed on the same computer. If you wish to return to a previous version of the application, uninstall (delete) the currently installed version first, then reinstall the previous version. Continue 28 Updating, Deleting and Repairing the Application (Continued) Deleting the application You can use either of the following methods to uninstall (delete) the application from your PC. Method 1: Delete from the Control Panel of the PC From the Start menu, click "Setting" "Control Panel" "Add/Remove Programs". Method 2: Use the installer file for the currently installed version to delete the application Note The application cannot be deleted by launching the installer file of a version different from the installed version. To do so, launch the installer file for the same version. 1 2 3 Double click the "PioneerAdvancedMCACC_e_ver_*_*. exe" file The InstallShield Wizard appears. . Select "Next". Select "Remove", then select "Next". Continue 29 Updating, Deleting and Repairing the Application (Continued) 4 Select "Remove". 5 Click "Finish". This completes the deletion of the application. Continue 30 Updating, Deleting and Repairing the Application (Continued) Repairing the application The repair function can be used for example if desktop shortcuts have been deleted, etc. , to restore the application to the same conditions as when it was first installed.
