Connecting a PC for Advanced MCACC output

When using the Acoustic Calibration EQ Professional (see page 43) to calibrate the reverb characteristics of your listening room, you can graphically check the results on your computer connected to this receiver. Also, when the Full Band Phase Control function is activated, you can visually check the calibrated characteristics of group delay of the speakers and the corrected characteristics of group delay processed by the exclusive correction filter by installing the corresponding PC application on your computer.

Use a commercially-available RS-232C cable to connect the RS-232C jack on your computer to the 9-pin RS-232C jack on the back panel of this receiver (the cable must be cross type, female-female).

The software to output the results is available by contacting the Pioneer Authorized Distributor for your area (as listed on page 95 of this manual) as well as the instructions necessary for using it.

Please make sure your system meets the following requirements:

•Operating system must be Microsoft® Windows® XP 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 operating instructions and/or the PC manufacturer for more information on making the proper port settings.

•System must have internet access.

•Connect your computer to the RS-232C jack on the rear panel of the receiver.

Make sure that the receiver and all connected components are switched off and disconnected from the power outlet when you do this.1

Use a commercially-available cable to connect the RS- 232C jack on your computer to the 9-pin RS-232C jack on this receiver. See the documentation provided with the Advanced MCACC application for more information.

It will take about ten seconds for the transmission to complete, then you will be able to analyze the output on your computer. Since the data will be cleared from the receiver when you restart reverb measurement or turn off the receiver, you might want to save the information on your PC after measurement.

3When you’re finished, press RETURN.

You will return to the Data Management menu. Continue with other settings in the Data Management menu if necessary. Press RETURN again to exit the Data Management menu.
