About this manual
These are the Operating Instructions for an application which displays on your computer screen the
listening room reverberation frequency characteristics and the MCACC parameters measured by the
Advanced MCACC function of your VSX-23TXH, VSX-21TXH, VSX-9140TXH or VSX-9040TXH.
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”
functions of the receiver itself (see page 84 of the receiver’s Operating Instructions), namely to display the
reverberation characteristics of the listening environment. 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
• 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.
