Only one filter can be used, but the response can be made smoother by taking measurements in several locations and averaging them. In consideration of the sound spread in the main listening position, it is recommended that measurements be taken in 3 or more positions. For example, if the listening position is a sofa seating three persons, frequency response measurements might be taken at each of the three ear locations. Channel balance will degenerate if measurements are too heavily weighted to one side or the other. These measurements can be repeated as many times as desired, merely by moving the microphone and clicking the [Take Measurement] button again. The measurement values for each sweep signals are displayed in the corresponding columns.

If the sound beam is blocked by a person, another noise occurs and distorts the measurement, or otherwise if you wish to delete a recorded measurement, click the [Clear last measurement] button. To delete all measurement values, click the [Clear all measurements] button. Click on the [Next] button to proceed to the next page.
