5. ERGO Calibration Software (ERGO Cal)

If the Focus measurement was Ok, ERGO will instruct you to place your measurement mic in Room Position 1, then click Enter. (Figure 5.18)

If there was a problem with the measurement, ERGO will dis- play the information and instructions for the next step.

5.2.4Room Position Measurements

The number of room positions needed depends on the value of Room Knowledge. If it is below 90% after the third measurement, ERGO Cal automatically includes extra room measurements until a Room Knowledge of 90% or better has been achieved.

The remaining measurements should be taken from random positions in the room with random orientations of the microphone. Choosing these positions and orientations is a breeze. All you have to do is place the microphone at different positions in the room and in different orientations. It is important to perform well-spaced measurements to get a covering image of the acoustical properties in the room that is varying positions, heights, and orientations of the microphone.

For optimal room correction, make sure that the measurements are:

1.Performed more than 1 m (3 ft) away from the loudspeakers

2.Not performed behind the loudspeaker

3.Taken at a minimum of 50 cm (1.5 ft) between each measurement

The following illustration shows the steps listed above. (Figure 5.19)

Once you’ve placed your mic in an acceptable location, you may begin.

This process is repeated at least three times and until the Room Knowledge reaches 90%.
