<p>PROBLEM TO BE SOLVED: To provide an intelligent audio source selection circuit executing the most part of necessary switching by it itself. SOLUTION: Input means for source signals F1, F2, NA and NB which are supplied by audio sources Q1 and Q2, a processor V forming plural pairs of signals connected in one channel from the source signals, a source selection logic device Qs to which the channel of the processor V is supplied, and output means which are connected to the signal output of the source selection logic device Qs and which form each output channels Co1, Co2... are installed. The processor V has an automatic audio mode setting device generating intermediate channels Cz1, Cz2... from the source signals F1 and F2, NA and NB in accordance with a source association mode and an application association mode, supplying them to the source selection logic device Qs and selecting them as the output channels Co1, Co2....</p> |
