Ref: DMS20

£579.00 excl. VAT £694.80 inc. VAT
Only UK orders accepted

The DMS20 Digital Microphone Station comprises a sloping desk console with a flexible gooseneck paging microphone, and is designed to work with the whole range of ASL Safety & Security Voice Alarm and Public Address systems. Twenty zone selection switches are provided, each having a ‘Busy’ LED and a ‘Select’ LED. A single 'Push To Talk' switch and associated ‘Speak Now' LED are also provided.

An in-built signal limiting automatic gain control is provided to help compensate for varying operator technique.
A processor within the Paging Microphone interfaces all LEDs and switches to the DSP Router by means of a serial interface, while microphone audio is provided as a balanced 0 dBu (nominal) analogue signal. All connections are provided through CAT5 cabling terminated with an RJ45 connector.

The microphone’s processor is also responsible for generating an outgoing low-frequency surveillance tone which is used to monitor the audio connection to the VAR Router, while microphone capsule monitoring is performed by injection and monitoring of a signal such that either open or short circuit of the capsule or associated wiring will indicate a fault.
