b. Setting the measurement volume level
The measurement volume – also called the calibration volume – is a recommended
maximum volume. It is important that you always judge whether the measurement volume
is too loud. The calibration volume should not be so loud that it causes:-
1. uncomfortably loud sounds that are inconvenient to you and your environment, or
2. damage to your loudspeakers.
Connect the microphone to the microphone input found on the right side of the back panel.
Thereafter, place the microphone, using the microphone stand, in an appropriate
focus/listening position. This location should be at your main listening position, typically
more or less centered between the loudspeakers.
Make sure that the height and the orientation of the microphone corresponds to your
typical listening height and direction as illustrated in figure 3.
Fig 3: Measurement of main listening position
When the microphone has been correctly connected and placed in the focus position, you
are ready to set the calibration volume. The calibration signal is a combination of the high
and low frequency measuring signals and is only presented in your left loudspeaker. The
signals sound very artificial and disharmonic due to the fact that they are made up of pure
tones at different frequencies. Press enter to confirm and to commence the calibration
process.
