The Contacta STS-K002L-G and STS-K002L-B Surface Mount Talk Through Glass speech transfer system helps customers hear and be heard when needing to talk through glass safety screens and partitions. An integral loop driver also helps hearing aid users to hear more effectively by using their Telecoil switch.

Such screens are a vital addition to reception desks in Hospitals & Doctors Surgeries during the current Coronavirus outbreak.

This unit is especially quick & easy to fit as the speakers are surface mounted. 

The customer facing speakers are freestanding to suit your installation and the microphone is built in too.

The  STS-SU1-G / STS-SU1-B noise cancelling staff microphone has an integral speaker and benefits from a semi-rigid stem, adjustable neck and mute switch.

The energy saving STS-A31 amplifier offers full duplex communication and it can be fitted easily to the underside of the counter using the built in mounting points. It also has a constant current loop driver for the IL-AE99 hearing induction loop also supplied in the kit.
