It comes in a plastic box in colored ABS that encloses a microphone of excellent quality.
The connection with the module takes place by means of a small plug-in connector di-
rectly on the front of the AA-600 device. The microphone can be positioned behind a
panel to create a VoIP communication intercom system. The two remaining wires must
be connected to the call button on the carrier panel, if any.
