 (b) PA announcement from cockpit From the cockpit a PA announcement is initiated with the handset or with the equipment connected to the Audio Management Unit (boomset, microphone and oxygen mask). The audio signal is transmitted from the handset directly or from the equipment connected to the AMU via AMU to the director. From the director the signals are transmitted to the DEU type A, which sends the signals either directly or via PISA to the loudspeakers. For a detailed description, how to use the AMU, see Audio Management (Ref. 23-51-00).
