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)
