[. . . ] The application can also be used to display the measurement values stored in the receiver's MCACC memory. Requirements for using the application on your PC · The computer must be a PC functioning with one of the following operating systems: Microsoft® Windows® Vista Home Basic/Home Premium/Ultimate SP1, Windows® XP Professional/Home Edition SP3 or Windows® 2000 Professional SP4. · The monitor must have a display resolution of 800 x 600 dots (SVGA) or greater. · An RS-232C port connector is necessary for graphical output. Refer to the PC's operating instructions and/or the PC manufacturer for more information on making the proper port settings.

Main features of the application 1. [. . . ] : Displayed in three dimensions. Type (Reverb display only) The reverb characteristics graph display type can be changed. Each Ch: All the channels are displayed individually. The "Each Ch" display type is set when EQ calibration is performed with the reverberation type set to "ALL CH ADJ". Pair Ch: Composite reverb characteristics for the left and right pairs of the "Front", "Surround" and "Surr Back" channels are displayed. The "Pair Ch" display type is set when EQ calibration is performed with the reverberation type set to "SYMMETRY" or "FRONT ALIGN". Displays 3D graphs with rotating. a Demo a.

In frequency display mode, it becomes the channel axis. 16 Group Delay [msec] This axis indicates the group delay amount (length of group delay time). 17 Freq [Hz] This is the frequency axis. 18 Channel This is the channel axis. 19 List display/individual display selector buttons All the MCACC memories are displayed when "ALL Memory" is selected, individual MCACC memories are displayed when set for individual displays ("Memory1", etc. ). Continue 15 Application Operations (Continued) Saving graphs in data files You can save measurement data received from the receiver on your PC. 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. 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. Figure 2 Level (dB) Time period point to be selected Time (in ms) Low frequencies High frequencies Continue 19 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. Figure 3 Level (dB) Time period point to be selected Time (in ms) Front left channel Front right channel 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. 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. Instead of selecting 30 to 50 msec, try another time period. [. . . ] If the trouble cannot be rectified even after checking the points listed below, ask the Pioneer Service Center specified on your warranty card. 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. [. . . ]
