Contacta STS-M74-02-B Discreet Microphone


The Contacta STSM7402 is a Discreet Microphone solution, designed to be mounted to a screen. It is ideal for use in any situation where one-to-one communication takes place at a counter, such as: banks, post offices, supermarkets, theatres, information centres or airports.

It is fitted using the included grey right angled bracket. The microphone is compatible with any Speech Transfer System that uses an STS-A31H amplifier. Alternatively, if you’d like to mount the STS-M74 to a computer screen then we would recommend looking at the STS-M74-02.
