What it is
Summary
AI-generated from vendor-published content · May 31, 2026
The HLD2 is the amplifier unit that drives a hearing loop at a service counter — it takes audio input from a microphone and generates the electromagnetic field that telecoil-equipped hearing aids and cochlear implants pick up directly. It's designed for one-on-one counter situations: a bank teller, pharmacy window, or reception desk where one staff member speaks to one customer at a time. The driver stays on continuously, so a hearing aid user just switches to T-coil mode and receives clear audio without having to ask for anything or handle extra equipment. This is a component, not a complete system — you'll also need a compatible loop aerial (the wire antenna) and a microphone, which Contacta sells separately or as a bundle. Built-in AGC and noise gate help with audio quality in noisy environments, and the energy-saving standby mode is a practical consideration for installations that run all day.

What Setup Looks Like
- With a guide
- Mount the HLD2 unit at the counter location and connect the loop aerial wire in the configuration specified for your counter dimensions.
- Connect a compatible microphone to the mic input.
- Power on and verify status LED indicates normal operation — test with a telecoil-equipped hearing device.
- Full installation typically takes 1-2 hours with the included documentation. See manufacturer support resources for detailed instructions.
- With professional help
- An AV installer or hearing loop specialist should verify loop field strength meets IEC 60118-4 standards using a field strength meter.
- In environments with significant background EMI (fluorescent lighting, computers), professional calibration of the AGC and noise gate settings will improve performance.
