Induction loop system with low-overspill up to 300m²

ref. PROLOOP LOS

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)
