Active loop amplifier with dynamic compressor for setting up an inductive hearing system in large rooms up to 750 m². The inductive transmission of audio signals allows users of hearing aids with a "telephone coil" or inductive receivers such as the LR-202 to receive audio signals. One advantage of inductive hearing systems is the wireless transmission, allowing users to move freely within the loop. Inductive hearing systems are used for various applications, such as aids for the hearing impaired in churches, theaters, cinemas, waiting and lounge areas, as interpreter systems, and during lectures in museums, exhibitions, etc. In inductive hearing systems, an induction loop consisting of a wire winding is installed in the floor, wall, or ceiling area and is powered by a current amplifier. This creates a magnetic field within the loop that induces a voltage in the telephone coil of the hearing aid or in the inductive receiver. This voltage is then converted back into an audio signal in the receivers.
