Humantechnik Proloop LOS Induction Loop Amplifier

Low overspill induction loop systems have traditionally required several devices, complex design, and high labour costs end to end... Until Now.
The Proloop LOS low overspill system by Humantechnik brings a new level of flexibility, configurability and affordability to assistive listening devices.
A low overspill solution has never been simpler.

The PROLOOP LOS is a compact system designed to operate low overspill systems.

It integrates the entire electronic configuration required in a single enclosure to provide a flexibly sized, reliable low-overspill solution for the coverage ofadjacent event rooms and assembly halls up to a size of 300 sq meters

The system is equipped with Automatic Gain Control (AGC) to produce stable sound with outstanding speech reproduction, even under difficult acoustic conditions. The values/data required to test the quality of the induction loop system can be conveniently picked up via anintegrated monitor output.

Features:

  • Uniform coverage throughout the room (no dead spots in the middle of the room) / No signal fluctuations when hearing-aid user moves his/her head

  • No signal fluctuations when hearing-aid users move around
  • Reduced sensitivity to architecture-related magnetic fields

  • High efficiency, low power consumption.

  • 19? 2RU rackmount enclosure
  • Well suited for retrofitted installation in theatres,cinemas, concert halls, schools, conference rooms
