Induction loop system with low-overspill up to 1000m²

ref. PROLOOP LOSplus
  • As a ready-for use system for operating low-overspill systems in large rooms of up to 1,000 m², the induction loop amplifier PROLOOP LOSplus has all the required electronic configurations in one single casing.
  • Each of the two XLR(F) inputs can be configured as LINE (balanced) or as microphone input (unbalanced).
  • On MIC mode it is possible to activate the function : gain control and 15V phantom power for condenser microphones.
  • The high-performance amplifier has an Automatic Gain Control (AGC) that also guarantees stable sound with excellent speech reproduction even in difficult acoustic conditions.
  • For acoustic quality controls on the induction loop outputs A and B, the PROLOOP LOSplus has a monitor output for connection of headphones
  • The equipment provides an output of up to 2x12A RMS and guarantees secure audio transmission.
  • Reduced sensitivity in respect to architecture-related steel reinforcements
AGC Sets the voltage and current for continuous signals such as oscillation and sinus curves to -10 dB after 0.6-1 seconds. Short pulses and normal program signals are not limited.
