The Ampetronic C5-1N is the networked version of the C5-1 single-output perimeter hearing loop driver, delivering 5 A RMS of loop current from a 1U rack unit. Its Ethernet port gives remote adjustment, status and loop measurement monitoring, and email fault alerts. It suits meeting rooms, classrooms, places of worship, council chambers and lecture rooms where the loop needs to be checked without a site visit.

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, 5 A RMS (7.1 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
Two balanced mic/line inputs with switchable 24V phantom power, plus a 100V line input
Compatible with Loopworks Measure LoopLink for automated driver control
Built-in test tones and speech optimised AGC
Passive cooling, no fan
