ABSTRACT:
A multichannel predictive gain amplifier system including a device for receiving input from a first channel and from a second channel, a variable gain amplifier, and a gain setting circuit for setting the gain of the variable gain amplifier. A switching device responsive to the input from the first and second channels sequentially connects each channel first to the gain setting circuit for determining the desired gain for that channel and then to the variable gain amplifier set to that desired gain.
