c. Focus Measurement
When the calibration is OK, press enter to start the measuring process and the following message will be displayed. Each measurement comprises four steps: a low and a high frequency measuring signal first in the left and then in the right channel. The length of each measurement depends on a combination of the measurement volume, set in the calibration process, and the background noise in your local environment. Typical measuring times for the low and high frequency measuring signals are 25 and 5 seconds, respectively. As mentioned, the measuring signals sound artificial and disharmonic due to the fact that they are made up of pure tones at different frequencies. It is advised that you do not to sit in the listening position during this measurement.
The measurement will stop prematurely if an error occurs during the measuring process. In this case, the error message is displayed. Press enter to continue and the following is displayed.
If the error needs correcting this should be done at this point (see RoomPerfect™ troubleshooting), thereafter press enter to retry the measurement. The measurement procedure will start again.
A measurement has ended successfully when the last measuring signal stops and the display shows a RoomKnowledge rating, as in the following.
Press enter to continue.
Do not sit in the listening position during focus measurements.
