Off-Panel Speaker Mounting
Typically, the speaker is connected to the appropriate motherboard connector via a cable. The
cable length enables the device to be placed within 1 m from the
2N

motherboard.
In
this case, mind the electrical safety, see below!
•
Warning
Make sure that the microphone hole is sealed against the noise that might get into
the microphone through the gap between the cabin wall and the mounting panel.
The microphone is supposed to receive sounds from the cabin only and not from
the shaft or the

installation cavity!
•
Caution
Installing the speaker separately, make sure that the grid does not surpass the
speaker dimensions in any case to eliminate the acoustic fault between the
speaker front and back sides!
•
Accident Risk
Make sure that the 50mm speaker is mounted on an insulating (non-metal)
surface. Otherwise, request an external panel, see the figure below (not included in
the delivery).
•
Caution
We do not recommend you to install the microphone and speaker on completely
different cabin sites (ceiling and wall, e.g.) as the users should find the speaker
(grid/perforation) easily and then speak into the microphone near it.
•
Caution
Should there be an acoustic feedback between the microphone and the speaker
(echo), turn down the speaker volume.
