Contacta “Above the Counter” loop kit with Halo microphone

General Description

The Contacta “Above the Counter” Loop Kit is a complete system designed for counter installation and is most suitable for ticket counters, reception desks, and other point of sale locations. The aerial is combined within the sign and is fixed to the counter or desk surface, enabling users to easily identify the loop and get maximum benefit from it. The unit can be fitted into many positions due to its low profile design.

The system comprises of a loop amplifier, noise-cancelling Halo microphone, loop sign with integrated aerial, power supply and fixings.

For use in any situation where one to one communication takes place at a counter, booth or desk, for example: Banks, Post offices, Supermarkets, Theatres, Information Centres, and Airports.
