DMS6000 Series

Compact Case, 1U Rack mounted and 3U Nest Mounted.

DMS6000 sound stores are based on industry standard MP3 compression. Audio data is stored on SD memory cards and can be recorded using any PC equipped with a SD card reader. Message playback can be initiated in a number of ways via: Direct Trip inputs, RS485 commands, or Command file selection. 


The DMS range of sound stores are ideally suited to audio applications in theme parks, multi-lingual applications, sound effects, public announcements or directions, emergency evacuations, background music and advertising, museum or trade displays, and numerous other applications.

Available Models:

DMS6000-PCB: Card only for 3U Subrack units or custom housing.
DMS6000-1U: 1U 19″ rack mountable case + DMS6000 card
DMS6000-CC: Compact case with DMS6000 card. (Supplied with external power supply)
DMS SUBRACK: 19″ 3U subrack capable of holding 8 cards. (Supplied with external power supply)
