Summary of Contents for Pioneer SC-25

  • Page 1 Operating Instructions – Advanced MCACC PC Display Application Software – audio/video multi-channel receiver...

  • Page 2: About This Manual

    The functions of the Advanced MCACC application are used with the same purpose as the “Reverb View” and “Group Delay” functions of the receiver itself (see pages 116 and 120 (SC-27, SC-25)/102 and 105 (SC- 9540) of the receiver’s Operating Instructions), namely to display the reverberation characteristics of the listening environment and the group delay characteristics of the speakers.
  • Page 3 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 116 (SC-27, SC-25)/102 (SC- 9540) of the receiver’s Operating Instructions), allows you to choose the optimum time period for auto EQ setup.

  • Page 4: Installing The Application

    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. If a previous version of the Advanced MCACC application (“Ver. 1.1”, “Ver. 1.4”, “Ver. 2.0” or “Ver. 2.1”) is installed on your computer, please update the application.

When using USB connections, be sure to select the proper COM port...
  • Page 8 RS-232C cable. Proceed to step Select “Output PC” from “MCACC Data Check”. (See page 118 (SC-27, SC-25)/104 (SC-9540) of the receiver’s Operating Instructions.) The message “Start the MCACC application on your PC” appears on the monitor screen and the receiver enters the transmission standby mode.

    Receiving measurement data 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. Select “Receive” under “File” on the menu bar.
  • Page 10 Application Operations (Continued) Select the type of data to be received, then select “OK”. Select “Reverb” to receive the data for the room’s reverb characteristics, “Group Delay” to receive the data for the speakers’ group delay characteristics and “MCACC Parameters” to receive the data for the various MCACC parameters (measurements results).
  • Page 11 Application Operations (Continued) Graph and parameter displays (names and functions of parts) When measurement data is received, the graphs and parameters display window appears. The display window is divided into two items, “Reverb”, “Group Delay” and “Parameters”. Select the desired tab to switch to that window and display the respective details.
  • Page 12 Application Operations (Continued) Group Delay (graph of the speaker’s group delay characteristics) You can switch the display between the speaker’s group delay characteristics before calibration and the speaker’s group delay characteristics after calibration. You can also switch between the group delay characteristics for all channels and the group delay characteristics for individual channels.
  • Page 13 Application Operations (Continued) 1 Menu bar and menu icons You can choose the following commands from the application menus. File Opens a file that has been saved on the PC (see page 17). Open Closes a file. Close Save Save measurement data in a file (see page 16).
  • Page 14 Application Operations (Continued) Window Cascades files. Cascade Tiles files. Tile Minimizes the window. Minimize Arranges minimized icons. Arrange a. Available when two or more files are open. Help Displays definitions of terms related to the MCACC function and this application. Glossary Displays the version of the application.
  • Page 15 Application Operations (Continued) 11 Bar Graph Changes the type of graph display. The display switches between the band graph and bar graph by pressing this button. Reverb: Move the time axis. Group Delay: Move the frequency axis. 12 File memo Memos concerning the file (conditions at the time of measurement, etc.) can be stored for the different items.
  • Page 16 When you are finished saving data, you should (using the receiver controls) press “RETURN” to exit the Reverb Output PC screen. This takes the receiver out of transmission standby mode. (See page 120 (SC-27, SC-25)/106 (SC-9540) of the receiver’s Operating Instructions.) Note The CSV format file is often used to transfer data to applications such as databases and spreadsheets.

  • Page 17: Opening Data Files

    Application Operations (Continued) Opening data files You can open and display two or more data files to compare the data in the files. Select “Open” from the “File” menu in the menu bar. Select a file to display and click “Open”. The previously saved measurement data is displayed.
  • Page 18 “SYMMETRY” or “ALL CH ADJ” calibration settings in the receiver’s “Auto MCACC” function. (For details, see page 110 (SC-27, SC-25)/96 (SC-9540) 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.
  • Page 19 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 116 (SC-27, SC-25)/102 (SC-9540) of the receiver’s Operating Instructions).
  • Page 20 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).
  • Page 21 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.
  • Page 22 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 110 (SC-27, SC-25)/96 (SC-9540) of the receiver’s Operating Instructions.)
  • Page 23 How to Interpret the Graphs (Continued) 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”...

Measure the room’s reverb characteristics after equalization with the microphone at the same position as...
  • Page 25 How to Interpret the Graphs (Continued) Reading the group delay characteristics graph (Group Delay) Group delay characteristics graphs for before and after calibration can be displayed. By comparing the two, it is possible to check in detail the group delay characteristics of the speakers being used and the effect of calibration using the Full Band Phase Control function.
  • Page 26 Display of the MCACC parameters In addition to the reverberation frequency characteristics and group delay characteristics data measured with the Advanced MCACC function, all the parameters (results of measurements) set in the MCACC memories can be checked on the computer. Parameters that can be displayed 1.
