Maximum distance limit:
this function is not active by default. When activated the possibility of moving the
loudspeakers is reduced within the red dashed line. This limit represents the maximum loudspeakers distance
allowed from the DSP delay lines; if all the loudspeakers in the map were moved away from the listening point,
the red circumference would increase its radius and a gray circle would appear in the center to indicate the
forbidden area within which the speakers cannot stand. If activated, this function ensures that you can then
use the automatic delay calculation command. However this function may not be activated and the loudspeakers
be positioned at any distance even outside the red circle: the drawback is that the automatic delay calculation
command may not be able to calculate the delays based on distances.
Zoom out:
to reduce the image size.
Zoom fit:
automatically sets the optimal view.
Zoom in:
to enlarge the image size.
Loudspeaker distance:
allows you to enter the loudspeaker distance with the keyboard. You can also click and drag
the loudspeaker onto the map.
Loudspeaker angle:
allows you to enter the loudspeaker angle with the keyboard. You can also click and drag the
loudspeaker onto the map. The 0° angle is on the vertical axis upwards; the angles are positive in a clockwise direction.
Loudspeaker selection buttons:
allows you to select a loudspeaker and bring it to foreground if it is hidden by other
loudspeakers. Initially all the loudspeakers are in the listening point.
Close button:
allows you to close the loudspeaker position panel without saving the changes. The distances are
not updated.
Confirmation button:
allows you to update the positions of the loudspeakers but does not calculate the delays.
The set distances are visible in the output channels panel.

WARNING:
if an output channel is moved from one zone to another, its position is preserved but it is advisable to
recalculate the delays of both zones involved using the automatic delay calculation command on the output
channels panel.
Remark:
the center of the map, that is the center of the axes, represents the listening point.
Remark:
each zone has its own listening point with respect to which delays are calculated.
Remark:
only the channels belonging to the currently selected zone are displayed on the map
Remark:
the positions set for the output channels relate to the spatial location of the loudspeakers and are the same
for all sources of the device.
