STS-K003L Flush Mounted Speech Transfer System

The STS-K003L flush mounted speech transfer system is neat and unobtrusive, making this configuraion ideal for an aesthetically discreet installation. The microphone and loudspeaker modules on the customer side of the counter are fitted flush to the counter surface.

The STS-K003L is a two-way intercom specifically designed to aid communications where normal speech is impaired by the use of glass security screens or other similar barriers. Every system is controlled and powered individually and operates on a stand-alone basis.
The STS-K003L comprises a twin- channel audio amplifier, power supply unit, a microphone and speaker for the staff and a microphone and speaker for the customer. The microphone and speaker modules are supplied in various formats to enable the system to be installed in differing locations.

The STS-K003L operates on an “Open Duplex” basis, i.e. microphones and speakers are live simultaneously, similar to a telephone with no manual or automatic switching of the voice. This means that clipping of speech is not encountered whilst still allowing users to operate the system “Hands- Free”. Sophisticated electronic circuitry in the amplifier and purpose designed speaker and microphone modules ensure that the risk of acoustic coupling or “Feedback” is kept to a minimum.

The STS-K003L is ideal for use in:

  • Banks and building societies
  • Benefit agencies
  • Booking offices
  • Bureaux de change
  • Consulates and embassies
  • High security environments
  • Petrol stations
  • Hospitals and clinics
  • Passport offices
  • Post offices
  • Prisons and detention centres
  • Reception counters
  • Stations
  • Sales kiosks
