About this manual
These are the Operating Instructions for an application which displays on your computer screen the
listening room reverberation frequency characteristics, the speakers’ group delay characteristics and the
MCACC parameters measured by the Advanced MCACC function of your SC-LX81 or SC-LX71.
It explains everything you need to know to use the application, from installation to troubleshooting. You will
need to operate the receiver to use this application, so please refer also to the Operating Instructions
supplied with the receiver.
About the Advanced MCACC Application
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 51 and 52 of the Operating Instructions of the
SC-LX81/LX71), 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.
Requirements for using the application on your PC
• Operating system must be Microsoft
®
Windows
®
XP (Service Pack 2) or Windows
®
2000.
• CPU must be at least Pentium 3 / 300 MHz or AMD K6 / 300 MHz (or equivalent) with at least 128 MB
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 reverberation frequency characteristics of your room. You can choose to
see these measurements both with and without the equalization performed by this receiver (before
and after calibration).
2. Allows you to display 3D graphics of the group delay characteristics of the different speakers. (The
values before and after calibration can be displayed.)
3. Allows you to display a list of the Advanced MCACC parameters (the results of measurements).
4. Allows you to view graphs in a number of different formats.
5. Allows you to save the various measured data on the computer.
6. Allows you to make memos about the conditions in your room when you made the measurements,
etc.
7. Allows you to print the various graphs and the MCACC measurement values.
