How to Interpret the Graphs (Continued)

About the display of the reverb characteristics graphs before

and after calibration

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).

Graph of reverb characteristics before calibration

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

Graph of reverb characteristics after calibration

You can see that compared to the graph before calibration the lines for the individual frequencies move

vertically in parallel by the amount of equalization and converge near the specified point on the time axis

(30-50 ms by default).

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

comparison purposes.
