Operating Instructions – Adv anced MCA CC PC Displa y Application Softw are – audio/video multi-channel receiver.
2 About this manual These are the Operating Instructions for an appli cation which displays on your computer screen the listening room reverberation frequency characteris tics and the MCACC parameters measured by the Advanced MCACC function of your VSX-23TXH, VSX-21TXH, VSX-9140TXH or VSX-9040T XH.
3 About the Advanced MCACC Application (Continued) Things you can accomplish with this a pplication 1. Advanced EQ Setup, which you can do with the rece iver (see page 84 of t he receiver’ s Operating Instructions), allows you to ch oose the optimum time pe riod for auto EQ setu p.

7 Operations on the Receiv er and Cable Connections Connect the receiver and the computer i n order to disp lay on the computer the various data measured on the rec eiver itself. 1 Connect the receiver to your PC with an RS-232C ca ble. Before making or changing connections, switch of f the power and disconnect the power cord from the power outlet.
8 Operations on the Rece iver an d Cable Connections (Continued) 2 Perform the “Full Auto MCACC” operation on the receiver. (See page 41 of the receiver’s Operating Instructions.) The measurements her e are not re quired if the “Full Auto MCACC” operation has alr eady been perfor med be fore connecting the RS-232C cable.
9 Applications Operations This section explains operations t hat you do in the application, fr om receiving measurement data to displaying graphs and saving the data. Receiving measurement data 1 Double click the application shortcut icon on the PC desktop.
10 Application Operations (Continued) 4 Select the type of data to be received, then select “OK”. Select “Reverb” to receive the data for the r oom’ s reverb characteristics, and “MCACC Parameters” to receive the data for the various MCACC parameters (measurements results).
11 Application Operations (Continued) Graph and parameter displays (n ames 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” and “Par ameters”.
12 Application Operations (Continued) MCACC Parameters (list display of MCACC parameters) A list of the measurements in all the MCACC memories is displayed.
13 Application Operations (Continued) 1 Menu bar and menu icons Y ou can choose the follo wing command s from the application menus. File Open Opens a file that has been saved on the PC (see page 17 ). Close Closes a file. Save Save measurement data in a file (see page 16 ).
14 Application Operations (Continued) 2 Display item selection tab A graph for the reverberation freque ncy characteristics or the MCACC parameter list is displayed. The “Group Delay” function is not used on this recei ver . Nothing is displa yed if it is selected.
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 bu tton. 12 File memo Memos concer ning the file (conditions at the time of me asurement, etc.
16 Application Operations (Continued) Saving graphs in data files Y ou ca n save measurement data received from the r eceiver on your PC. Data received at one time is saved in one file. 1 To save measure data, choose “Save” from the “File” menu.
17 Application Operations (Continued) Opening data files Y ou can open an d display two or more data files to compar e 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”.
18 How to Interpret the Graphs As indicated in Things you can accompl ish with this application (page 3) , the reverb characteristics graph can be used as reference when determining the calibra tion time posi tion with the receiver’ s “Advanced EQ Setup” function.
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).
20 How to Interpret the Graphs (Continued) Pattern 2: Different reverb charac teristics for different channels If the reverb characteristics differ for the different channels as shown in Figu re 3, eq.
21 How to Interpret the Graphs (Continued) Checking steps to improve your room’s reverb characteristics The reverb characteristics of your liste ning room graphs ar e evident from the graphs . For your reference, the following four examples explain how differ ent types of rooms appear in the graphs.
22 How to Interpret the Graphs (Continued) Case 3: Specific frequency show s unusual reverb characteristics There is probably something in the room that affects the reproduction of that frequency . If possible, tr y to find an arrangement that reduces the effect.
23 How to Interpret the Graphs (Continued) About the display of the reverb characteristics graphs before and after calibration By comparing the reverberation charac teristics graphs before and after c alibration, you can check how the reverb characteristics have been calibrated.
24 About the types of displays of the graph for the reverb characteristics after EQ calibration For “SYMMETRY” or “FRONT ALIGN” • The display type is set to “Pair Ch” ( page 13 ).
25 Display of the MCACC parameters In addition to the reverberation frequency ch aract eristics data measured with the Advanced MCACC function, all the parameters (results of measur ements) set in the MCACC memories can be checked on the computer . Parameters that can be displayed 1.
26 Updating, Deleting and Repairing the Application Updating the application A new installe r is made av ailable on th e download site w henever the Advanced MCACC application is updated. Y ou can download the new installer and use it to overwrite (update) th e application on your PC.
