CONTACTA Above-the-Counter Audio Induction Loop System with Mouse Mic

The CONTACTA Above-the-Counter Audio Induction Loop System is designed to deliver crystal-clear sound directly to hearing aid wearers, even in noisy environments or where speech clarity is compromised. This innovative solution integrates the hearing loop aerial within a signage sticker, which can be affixed to a counter, desk, or glass surface, allowing customers to easily identify the loop point and benefit from enhanced audio reception. Thanks to its low-profile structure, the unit can be installed in a variety of positions without intruding on your space.

The system is packed with advanced features to ensure optimal performance and energy efficiency. It utilises microprocessor control and includes an energy-saving “green” standby mode, plus advanced audio processing with AGC, compression, and noise gate functions. A constant-current loop drive ensures consistent output, while continuous self-testing guarantees reliability. The isolated audio line input allows connection to alternative audio sources (optional), and power and LED status indicators keep you informed of the system's state.
