The C5-2 Series hearing loop drivers from Ampetronic mark a substantial development in assistive listening technology. C Series units feature digital signal processing and networking functionality, and enable fast, accurate setup and adjustment via a very simple and easy to use user interface.
Ampetronic has engineered the C Series to offer the high end performance, consistency and certainty of results usually associated with top of the range induction loop drivers, all for the price of a mid-range amplifier. Class ‘D’ drivers built into the C Series ensures low running and maintenance costs.
Network versions enable installers, technicians and facilities managers to remotely control the driver and monitor its condition status along with resistance and induction measurements. Fault condition alerts via email or Telnet provide reassurance that an operator will be informed of any issues with performance delivery.
The C5-2 features 5 Amps RMS current loop output, plus ample voltage headroom, making it suitable for a wide range of applications. Installation can be performed with total confidence; unique, multi-stage filtering ensures compatibility with other systems and global EMC regulations. These products are designed to form part of a system that can meet all of the requirements of the international loop performance standard IEC60118-4, and the relevant parts of IEC TR 63079.

Indicative metal loss scenarios are based on: Moderate – Calculated using “Concrete with moderate reinforcement” mode in Loopworks Design. Typical loss allowance of 5dB. High – Calculated using “Profiled Steel Deck” and “Metal System Floor” modes in Loopworks Design. Typical loss allowance of 9dB. All calculations based on square rooms. Perimeter loop systems modelled as single-turn loops using 2.5mm² single wire. Loops installed at height (essential in larger rooms). Multiloop systems modelled as floor-level installations using 3.0mm² Flat Copper Tape. *Optimised
