* Required Fields


The Contacta STS-K001L-G and STS-K001L-B Bridge Bar Kit is a speech transfer system to help 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.

Ideal for banks, ticket offices and post offices.

The speakers are connected with a fixed length bar with integral directional central microphone.

The  STS-SU1-G / STS-SU1-B / STS-SU1-SS 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.
