  • Control device for induction loop system
    Patent number: 9307329
    Abstract: There is provided a control device (220) for an induction loop system configured to: generate a calibration signal (202) having a known amplitude and frequency; feed the calibration signal (202) to an induction loop amplifier (106); detect level of electric current at the output of the induction loop amplifier (106); and determine an adjustment model (400) on the basis of the detected level of electric current and the known amplitude and frequency, wherein the adjustment model (400) is for adjusting the amplitude of a to-be-fed output signal (200) based on the frequency of a to-be-received input electrical audio signal (105) such that the level of the electric current at the output of the induction loop amplifier (106) is within predetermined limits.
