Terminal of a safety reasons, the bidirectional audio transmission of a direction as well as a method of compensating conducted attenuations and distortions of a via a transmission line the terminal supplied electric audio signal
Terminal of a safety reasons, the bidirectional audio transmission of a direction as well as a method of compensating conducted attenuations and distortions of a via a transmission line the terminal supplied electric audio signal
Terminal (3) of a safety reasons, the bidirectional audio transmission of a direction (1), in particular, is formed, which by way of an associated transmission line (4) electrical audio signals can be supplied, with adjustable means (9) to compensate for conducted attenuations and distortions in the supplied audio signal, wherein the compensation means (9) automatically as a function of the received audio signal can be set, characterized in that in order to adjust the compensation means (9) a computer unit (11) is provided, the means (13) for storing a value of function, in the input level of the supplied signal to control variables for the compensation means (9) are assigned in such a manner that an essentially constant output level of the compensation means (9) is adjustable, and that, in order to set a the ambient conditions of the terminal (3) volume, which is adapted to a final amplifier is provided, the gain factor by means of a of the arithmetic unit (11) digitally controlled potentiometer (15) can be predetermined.
