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%.
