Acoustic Calibration EQ Professional

This setup minimizes the unwanted effects of room reverberation by allowing you to calibrate your system based on the direct sound coming from the speakers. It can also provide you with a graphical output of the

frequency response of your room.1

Finish

Use / to select the channel.

Use / to select the frequency and / to boost or cut the EQ. When you’re finished, go back to the top of the screen and press  to return to Ch, then use / to select the channel.

The OVER! indicator shows in the display if the frequency adjustment is too drastic and might distort. If this happens, bring the level down until OVER! disappears from the display.

Tip

Changing the frequency curve of one channel too drastically will affect the overall balance. If the speaker balance seems uneven, you can raise or

lower channel levels using test tones with the TRIM feature. Use / to select TRIM, then use / to raise or lower the channel level for the current speaker.

3 When you’re finished, press RETURN.

You will return to the Manual MCACC setup menu.

How to use Acoustic Calibration EQ Professional

If you find that lower frequencies seem overly reverberant in your listening room (i.e. it sounds ‘boomy’), or that different channels seem to exhibit different reverb characteristics, select EQ Pro. & S-Wave(or ALL) for the Auto MCACC setting in Automatic MCACC (Expert) on page 44 to calibrate the room automatically. This should provide a balanced calibration that suits the characteristics of your listening room.

If you still aren’t satisfied with the results, the manual Advanced EQ Setup (below) provides a more customized calibration of your system using the direct sound of the speakers. This is done with the help of a graphical output that can be displayed on-screen, or using a computer (with software available from Pioneer

see Connecting a PC for Advanced MCACC output on page 72).

How to interpret the graphical output

The graph shows decibels on the vertical axis and time (in milliseconds) on the horizontal axis. A straight line indicates a flat-response room (no reverb), whereas a sloping line indicates the presence of reverberation when outputting test tones. The sloping line will eventually flatten out when the reverberant sound stabilizes (this usually takes about 100 ms or so).

By analyzing the graph, you should be able to see how your room is responding to certain frequencies. Differences in channel level and speaker distance are taken into account automatically (compensation is provided for comparison purposes), and the frequency measurements can be examined both with and without

the equalization performed by this receiver.2

Setting Acoustic Calibration EQ Professional according to your room characteristics

Using the manual setup, you can set the time period at which the frequency response is analyzed, pinpointing the time that is best for system calibration with your particular room characteristics.

Note

1This system allows you to customize your system calibration with the help of a graphical output that can be displayed on-screen, or using a computer (with software available from Pioneer—see Connecting a PC for Advanced MCACC output on page 72 for more on this).

2Note that due to an effect known as ‘group delay’, lower frequencies will take longer to be generated than higher frequencies (this is most obvious when comparing the frequencies at 0 ms). This initial slope is not a problem (i.e. excessive reverb) with your listening room.
