Audio Control Module 2

 

Emergency personnel, security staff or public utility workers: All of them are sometimes tasked with informing and warning the public. This can be required in a disaster situation, in traffic or in general deployment situations. Usually, the only way to do so is a public address microphone which is connected to the exterior loudspeakers of a tone sequence system.

If additional audio - or low-frequency - sources are to be imported, other media such as MP3 players or cellphones are usually at hand. For these devices the ASM 2 is the interface to the tone sequence or amplifier for public address.

The audio sources are selected via a CiA447-compatible control unit, routed to the amplifier’s audio frequency inputs from the ASM 2 and played through the pressure chamber loudspeakers. Additionally the ASM 2 offers the option of a 10-second voice recording which can be played in a continuous loop or alternately with the tone sequence. The flexibility and quality of audio frequency signal processing are two more assets completing this product.
