Induction loop system with low-overspill up to 300m²

  • The PROLOOP LOS is an induction loop amplifier for the operation of low-overspill systems and it includes the complete range of electronics required in a single enclosure.
  • Suitable for theater, meeting room where several loops have to be put side by side without crosstalk.
  • Various audio inputs (XLR-3 / Jack 6,35 mm / RCA) allow sound equipment connectivity without external adaptation.
  • Automatic Gain Control (AGC) maintains a constant magnetic field that produce stable sound with outstanding speech reproduction.
  • Monitor output allows ,among other, to chained the amplifier to an other loop amplifier
  • Uniform coverageof magnetic field
  • No signal fluctuations when hearing-aid user moves his/her head
  • Reduced sensitivity of magnetic field present on the room
  • High efficiency, low power consumption
  • Well suited for existing facilities, such as theaters, cinema, concert hall, meeting room or schools and homes (during a renovation of the floor)
