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 receiver.

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.

Important

The explanations concerning the “Group Delay” functions (“group delay characteristics of the speakers”, etc.) included in these operating instructions only apply for receivers supporting the Full Band Phase Control function.

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 the receiver’s Operating Instructions), 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

•The computer must be a PC functioning with one of the following operating systems: Microsoft® Windows® Vista Home Basic/Home Premium/Ultimate SP1 or Windows® XP Professional/Home Edition SP3.

•The monitor must have a display resolution of 800 x 600 dots (SVGA) or greater.

•The computer must be equipped with a USB port (a separate USB device is required to transfer measurement data from the receiver to the computer).

Microsoft®, Windows®Vista and Windows®XP are either registered trademarks or trademarks of Microsoft Corporation in the United States and/or other countries.

About the Advanced MCACC Application (Continued)

Things you can accomplish with this application

1.Advanced EQ Setup, which you can do with the receiver (see the receiver’s Operating Instructions), allows you to choose the optimum time period for auto EQ setup. You can use this application’s reverberation characteristics (Reverb) as a guide in choosing the best time period for your room. For details, see Deciding the time period for Advanced EQ Setup calibration (page 18).

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.

For details, see Checking steps to improve your room’s reverb characteristics (page 20).

3.The reverb characteristics after calibration can be displayed. This lets you to check the EQ effects of the Advanced MCACC measurements you have made.

For details, see About the display of the reverb characteristics graphs before and after calibration

(page 22).

4.The Group Delay graphs allow you to check the group delay characteristics before and after calibration.

For details, see Reading the group delay characteristics graph (Group Delay) (page 24).

5.The MCACC parameter display (Parameters) allows you to display on the computer all the parameters (measurement values) stored in the receiver’s MCACC memories.

For details, see Display of the MCACC parameters (page 25).

Operations on the Receiver and USB Connections

In order to display the various data measured on the receiver on the computer’s screen, perform the operations below to connect the USB device and transfer the receiver’s data.

1 Perform the “Full Auto MCACC” operation on the receiver. (See the receiver’s

Operating Instructions.)

The measurements here are not required if the “Full Auto MCACC” operation has already been performed. Proceed to step 2.

2 Select “Output MCACC data” from “MCACC Data Check”. (See the receiver’s

Operating Instructions.)

The message “Please connect your USB memory for the MCACC data, then press OK to output them.” appears on the monitor screen and the receiver enters the transmission standby mode. It is ready to send data to your USB device. (The display screen may differ, depending on the receiver’s model.)

Operations on the Receiver and USB Connections (Continued)

Note

•Do not disconnect the USB device or turn off the power under data transfer is completed.

•The graphs for both before calibration (“Before”) and after calibration (“After”) can be displayed on the screen displaying the reverberation characteristics graphs after Full Auto MCACC measurements (“Reverb”), but note that the graph displayed for the characteristics after calibration is a prediction of the reverberation characteristics after Full Auto MCACC with the EQ Type : SYMMETRY.

For details, see About the display of the reverb characteristics graphs before and after calibration

(page 22).

If you want to check the graph of the actually measured reverberation characteristics after MCACC calibration (not the prediction), measure the reverb characteristics again after calibration.

For details, see Displaying the reverb characteristics after EQ calibration (actually measured values)

(page 23).

•If calibration is performed with the Full Auto MCACC’s EQ Type set to anything other than SYMMETRY (to either ALL CH ADJ or FRONT ALIGN), the reverberation characteristics after calibration cannot be predicted, so the graph for the characteristics after calibration (“After”) cannot be displayed. In this case, the graph for the characteristics after calibration can be displayed by measuring the reverberation characteristics again with the same EQ Type as the type used for calibration. For details, see Displaying the reverb characteristics after EQ calibration (actually measured values) (page 23).

Applications Operations

This section explains operations that you do in the application, from opening measurement data to displaying graphs and saving the data.

Opening measurement data

1 Double click the application shortcut icon on the PC desktop.

You can also start the application by selecting “Program” “Pioneer Corporation” “Advanced MCACC” from the “Start” menu.
