If the position of the sound source (speaker) is fixed at a certain degree, set the tracking control to OFF.
1. Tracking control
Selects whether or not to enable tracking control. Set this function to ON when the sound source position is
not determined, and OFF when the sound source position is fixed.
2. Angle
Detects the sound and displays the sound source angle relative to the array microphone when Tracking
Control is set to ON.
Display range: −90° to 90°
Sets the sound source angle relative to the array microphone when Tracking Control is set to OFF.
Setting range: −90° to 90°
3. Distance
Detects the sound and displays the distance between the sound source and the array microphone when
Tracking Control is set to ON.
Display range: 0.5 m to 3.0 m or ∞ m (1.64 ft to 9.84 ft or ∞ ft)
Sets the distance between the sound source and the array microphone when Tracking Control is set to OFF.
Setting range: 0.0 m to 2.0 m (0 ft to 6.56 ft)
4. Tracking angle*
Sets the horizontal angle range within which the array microphone can detect the sound source. Set the
sliding bar within the setting menu or pointer (sound source position) to the desired position.
Setting range: −90° to 90°
Note
If the sound source is detected outside the range, the automatic sound source tracking function is disabled.
5. Tracking distance*

Note
If the sound source is detected outside this range, the automatic sound source tracking function is disabled.
23
6. Tracking sensitivity*
This is the threshold for sound source detection.
The sound source is detected whenever the input audio level is larger than the threshold value. Set the value
according to surrounding sound volume conditions.
Setting range: −24 dB to 0 dB
Note
It is recommended that the threshold value be set a little higher than the ambient noise level.
7. Tracking speed*
Sets the speed at which the microphone tracks the sound source. The larger the number, the faster the
tracking speed.
Setting range: 1 to 100
8. Audio gain control
Corrects the level. Selecting ON displays a light blue frame that indicates the effective distance. The range
can be changed with the pointer or sliding bar.
Setting range: 0.5 m to 2.0 m (1.64 ft to 6.56 ft)
9. Visual trail
Leaves a visible sound source position trail on the screen.
Selecting ON makes it possible to leave a visual sound source trail. The amount of time the trail is left on the
screen can be changed with the Duration setting.
