By comparing the reverberation characteristics graphs before and after calibration, you can check how the 
reverb characteristics have been calibrated. Select “Before” to display the graph of the reverberation 
characteristics before EQ calibration, “After” to display the graph of the reverb characteristics after EQ 
calibration. If you want to check the actually measured reverb characteristics after EQ calibration, see 

Displaying the reverb characteristics after EQ calibration (actually measured values) (page 24)

.

You can see that the reverb characteristics of the various frequencies of the different channels are uneven.

You can see that compared to the graph before calibration the lines for the individual frequencies move in 
parallel by the amount of equalization and converge at the specified point on the time axis.

• The graphs displaying reverb measurements both before and after calibration are displayed in 2-D for 

comparison purposes.
