Ampetronic C7-2N

The Ampetronic C7-2N networkable multiloop induction loop driver features digital signal processing with fast, accurate setup and adjustment via a simple user interface. The dual outputs facilitate an accurate and stable 90° phase shift - ideal for installing a low spill loop where confidentiality is an issue or where adjacent rooms have individual loops fitted. This system is also good for overcoming losses due to high metal content in the fabric of the building.

Three variants are available; this C7-2N networkable model, yhe C7-2 standalone model, and the C7-2D which additionally offers Dante control over your network.

Network connection enables 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 C7-2N features a 7 Amp RMS current loop output, plus ample voltage headroom, making it suitable for a wide range of applications. Two balanced inputs are provided for either line or mic level operation. Input 2 can alternatively be used for 100V line operation.

Ampetronic has engineered the C Series to offer the high end performance, consistency and certainty of results usually associated with top of the range hearing loop drivers. Class ‘D’ drivers ensure low running and maintenance costs.

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.
