Digital Paging Microphone
The APM1xx series are Digital Paging microphones with zone-selection buttons which are equipped
with a digital audio memory which allowing storage of addidional "chime" signals.
The gooseneck microphone is equipped with an electret capsule with cardioïd pickup pattern. A
built-in Compressor/Limiter with Automatic Gain Control controls the output level of the unit. There's
also an indication on the front plate, to give the person who's talking an impression of his voice level.
The complete operation, from microphone cell till signal output including all digital parts, is guarded. In
case of malfunction, there is a fault-indication. This is to make sure that when there is an emergency
call, the message arrives at the listeners.
When there are several paging units placed in a bus-structure, you can configure them with different
priority levels. The status of the audio-bus is indicated on the front panel (enable led).
