Rated 4.9 (120 reviews)
The Ampetronic C10-1N is a networked, single-output perimeter hearing loop driver delivering 10 A RMS of loop current from a 1U rack unit. Network control lets installers and facilities teams adjust the driver remotely, monitor loop resistance and induction, and receive fault alerts by email. It suits larger single spaces such as lecture theatres, theatres, conference rooms, sports halls and transport concourses, where a system needs to meet BS EN 60118-4 field strength.

Metal loss correctionMLC corrects the frequency response tilt caused by metal in the building. It does not make up the overall signal loss, which can be large, so loops in steel-framed buildings still need a proper design.
Features
Single loop output, 10 A RMS (14.1 A peak) at 1 kHz
Ethernet control via hosted web server, Telnet and SNMP
Remote monitoring of driver status, loop resistance and induction, with fault alerts by email or Telnet
Priority input option and custom dual-slope metal loss correction (network models)
Two balanced mic/line inputs with switchable 24V phantom power, plus a 100V line input
Status relay that opens on fault, for connection to building management or alarm panels
Compatible with Loopworks Measure LoopLink for automated driver control
Built-in test tones and speech optimised AGC
Variable speed fan, front inlet and rear exhaust
