  • Page 2: About This Manual

    “Group Delay” functions of the receiver itself (see pages 50 and 51 of the Operating Instructions of the SC-07/05), namely to display the reverberation characteristics of the listening environment and the group delay characteristics of the speakers. Using a computer provides cleaner, more easily readable graphs. The application can also be used to display the measurement values stored in the receiver’s MCACC memory.
  • 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 50 in 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.

  • Page 18 How to Interpret the Graphs Things you can accomplish with this application As indicated in 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.
  • Page 19 How to Interpret the Graphs (Continued) 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).
  • 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 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.
  • Page 23 How to Interpret the Graphs (Continued) Displaying reverb characteristics after calibration To display the graph of your listening area’s reverb characteristics with the equalization performed by this receiver (after calibration), you’ll need to select the “EQ ON” option from the “Reverb Measurement” menu. Using this graph, you can confirm the effects of MCACC calibration for your listening area.
  • Page 24 How to Interpret the Graphs (Continued) Receive and save the data by selecting “Output PC” from “MCACC Data Check”. When you receive and save this information on your PC, you will be able to see the graph of your listening area’s reverb characteristics with the equalization performed by this receiver (after calibration). The following graph shows the reverb measurement results after Advanced EQ Setup calibration (with a time period setting of 30-50ms): About the types of displays of the graph for the reverb...
  • 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.

    PC. If an error occurs, refer to the troubleshooting points below. If the trouble cannot be rectified even after checking the points listed below, ask the Pioneer Customer Support Division (USA) or Customer Satisfaction Department (Canada).
  • Page 34 Troubleshooting (Continued) 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.
  • Page 35 Troubleshooting (Continued) Try the following, in the order indicated. 1) In the setup 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.
  • Page 36 Troubleshooting (Continued) Reverb characteristics graph cannot be printed Cause: It is not possible to print reverb characteristics graphs displayed in the “ALL” mode. 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.
  • Page 37 Troubleshooting (Continued) 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.
