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 page 116 (SC-27, SC-25)/102 (SC-

9540) of 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 19).

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 21).

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 23).

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 25).

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 26).
