Multiplex transmission device for multiple-channel signals, especially multiple-channel audio signals
First Claim
1. A multiplex transmission device for multiple-channel signals, in particular multiple-channel audio signals comprising:
- a plurality of input channels, each of which receives an input signal;
a multiplexer having inputs and an output;
said input channels being connected with the inputs of said multiplexer;
an output channel which is connected to said output of the multiplexer for sending an output signal which is multiplexed from the input signals;
a control element being connected in each input channel for controlling the amplitude of the respective input signal; and
a regulating device being provided for controlling the control elements;
said regulating device using said output signal of said multiplexer as a regulating variable.

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.
