Abstract
A multiplex transmission device for multiple-channel signals, in particular multiple-channel audio signals, has a plurality of input channels, each of which receives an input signal, a multiplexer, the input channels being connected with the inputs of the multiplexer, and with an output channel which is connected to the output of the multiplexer for sending an output signal which is multiplexed from the input signals. A control element is connected in each input channel for controlling the amplitude of the respective input signal and a regulating device is provided for controlling the control elements. A special feature of the device consists in that the regulating device uses the output signal of the multiplexer as a regulating variable.
