About the Advanced MCACC Application
The Advanced MCACC application software allows you to view graphs of the reverb characteristics of your
listening environment on a PC. It works in the same way as "Reverb View" in the amplifier's "Acoustic Cal
EQ Professional" function (see page 58 in the amplifier's Operating Instructions), but the graphs are more
attractive and easier to understand by using a PC.
Requirements for using the application on your PC
• Operating system must be Microsoft Windows® XP, Windows® 2000, Windows® Millennium Edition,
Windows® 98 Second Edition, or Windows® NT 4.0 (Service pack 6).
• CPU must be at least Pentium 3 / 300MHz or AMD K6 / 300MHz (or equivalent) with at least 128MB
of memory, and your monitor must be able to display a minimum resolution of 800x600.
• 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. Displays 3D graphs of the reverb frequency characteristics of your room.
Acoustic calibration by MCACC made on the amplifier itself is not reflected in these graphs.
2. Allows you to view graphs in a number of different formats.
3. Allows you to save the measured reverb characteristics data on your PC.
4. Allows you to make memos about the conditions in your room when you made the measurements.
5. Allows you to print graphs.
Things you can accomplish with this application
1. Advanced EQ Setup, which you can do with the Manual Pro function of the amplifier (see page 58
in the amplifier's Operating Instructions), allows you to choose the optimum time period for auto EQ
setup. You can use the graphs displayed by the application as a guide in choosing the best time
period for your room.
For details, see How to Interpret the Graphs (page
2. Skewed reverb frequency characteristics in your listening room can prevent you from enjoying an
accurate sound field. The graphs displayed by this application are a powerful tool because they
allow you to check these reverb frequency characteristics at a glance. 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.
