[. . . ] 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 How to Interpret the Graphs (page 13). 2 Installing the Application Install this application on your PC by using the downloaded installer. You will find the installer in the folder that you specified when you downloaded the application. 1 2 Double click the "PioneerAdvancedMCACC_e_ver_*_*. exe" file The number after "ver" in the filename is the version number of the installer. . Click "Next. " 3 Click "Yes" (if you agree to the terms of the License Agreement). The destination selection screen of the installer appears. Continue Troubleshooting If an error occurs when you double click and you are unable to proceed with the installation. 3 Installing the Application (Continued) 4 Click "Next. " The application is installed in the indicated folder, and a shortcut icon is created on the desktop. To select a different folder to install the application, click "Browse. " 5 Click "Finish. " The installation is complete. You exit automatically from the installer. 4 Operations on the Amplifier and Cable Connections To display reverberation characteristics measured with the amplifier on your PC, you need to connect the amplifier to the PC. 1 Connect the amplifier to your PC with a RS-232C cable. Caution Before making or changing connections, switch off the power and disconnect the power cord from the power outlet. [. . . ] PC Output _ This completes the preparations for sending the measurement data to your PC. (To send the data, proceed to the next section Application Operations. ) Notes · The amplifier temporarily keeps the measured reverberation frequency data in its internal memory while waiting to send the data to the PC. · "PC Output" does not appear in the on-screen display when the amplifier does not have any reverberation frequency data to send to the PC. 6 Application Operations This section explains operations that you do in the application, from receiving measurement data to displaying graphs and saving the data. Receiving measurement data 1 Double click the application shortcut icon on the PC desktop. You can also start the application by selecting "Program" = "Pioneer Corporation" = "Advanced MCACC" from the "Start" menu. The application starts. 2 Select "Receive" under "File" on the menu bar. 3 Select the number of the COM port to which the RS-232 cable is connected and click "OK. " If you do not know which COM port number to select, try selecting each port in turn, beginning with "COM1. " COM port selection box Data transmission starts. (It should finish in about 10 seconds. ) When reception finishes, graphs of the received data appear. Note Refer the operating instructions of your PC for more information about COM port settings. Continue Troubleshooting If an error occurs when you select "Receive" and no data is sent. 7 Application Operations (Continued) Graph displays (names and functions of parts) When data is received, the first display to appear shows graphs for all channels (ALL display). This section explains the parts shown in ALL display and individual display.

Help Version Info Displays the version of the application. 2 Date and time Display the date and time when the measurement data was transferred to the PC. 3 Channel and frequency switch buttons Ch: Selects channel display mode (frequencies are displayed along graph depth axes). (See page 55 in the amplifier's Operating Instructions. ) Figure 4 Select the standard Acoustic Cal EQ. Front left low frequencies Level (dB) Front right low frequencies Front left high frequencies Front right high frequencies 0 80 160 Time (in msec) Notes · If you are not sure which time period to specify in Advanced EQ Setup, start by trying 20 to 40 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 amplifier, using the amplifier's Advanced EQ Setup function. Continue 15 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 16 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, you can use "Auto Pro. " of "Acoustic Cal EQ Professional" to automatically achieve the optimal calibration for the characteristics of your listening area. [. . . ] A window showing the version (Version 1. 1, etc. , ) appears. 1 2 Double click the new downloaded installer The Install Shield Wizard appears. . Click "Repair. " Continue 18 Updating and Deleting the Application (Continued) 3 Click "OK. " 4 Click "Finish. " This completes the updating of the application. Continue Troubleshooting If an error occurs when you click "Repair" and you are unable to proceed with the installation. 19 Updating and Deleting 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 downloaded installer to delete the application 1 2 Double click the "PioneerAdvancedMCACC_e_ver_*_*. exe" file The Install Shield Wizard appears. . Click "Remove. " 3 Click "OK. " Continue 20 Updating and Deleting the Application (Continued) 4 Click "Yes. " After you click "Yes, " the same screen may appear again. If it does, click "Yes" again. 5 Click "Finish.

The application is unstable, or does not work normally Cause: 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. 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. Cause 2: Installation of Advanced MCACC may fail because of incompatibilities with other applications. Try the following, in the order indicated. [. . . ]
