Magnetic loop system with low crosstalk

Magnetic loop system with low crosstalk

The Proloop LosPlus is a complete system ready to be connected to a low crosstalk installation covering a surface up to 1000 m². It includes all the necessary electronic configuration in one and the same housing.

This system is equipped with an automatic Gain Control (AGC) that guarantees the stability of the sound level of sound or voice, even in a difficult acoustic environment. The Proloop Losplus has a monitoring headphone output for verifying the quality of the audio signal transmitted on the A and B loop outputs.


AGCSets 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.
