Contacta STS-M74-01 Halo Microphone with Round BaseThe Contacta STS-M74-01 Halo Microphone is a compact halo microphone which comes on a round base for easy mounting. It is a compact and unobtrusive solution which 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 features built in noise cancelling and there is a halo light indicator at the base of the microphone stem. This lights up green when the system is working correctly and red when a fault is detected. The microphone is compatible with any Contacta speech transfer system which uses an STS-A31H amplifier. 

Alternatively if you'd like a larger microphone then we would recommend looking at the STS-M72 as an alternative option.
