SKU: 954.017UK Category:

Description

An over-counter loop system, providing clear communication with hearing aid wearers, especially where background noise is a problem or clear speech is restricted. The aerial is contained within the sign, which fixes to a counter or desk surface, enabling users to easily spot the loop and get maximum benefit from it. The unit can be fitted in many positions due to its low-profile structure. Complies with the following standards: CE, ROHS and WEEE compliant; BS EN 60118-4 in correct installations.

Features

Energy-saving “green” standby mode achieves a power saving of up to 80% during quiet periods
Advanced audio processing features, including AGC, compression and noise gate
Constant-current loop drive
Continuous self-testing
Isolated audio line input allows the driver to take alternative audio sources (optional)
Power and LED status indication
Magnetic field range of 800mm
