AUDIO SIGNAL SWITCHING DEVICE

摘要

PROBLEM TO BE SOLVED: To switch the distribution of the audio signals from the input to the output in a simple operation. SOLUTION: An output 21 (BUS 1) adds only the audio signals of fixedly selected input 11, input 13 and input 14 between the input 11 to the input 14 and outputs the added audio signals. An output 22 (BUS 2) adds the audio signal of the fixedly selected input 12 between all of the inputs to the signals of the input 13 and the input 14 that are dynamically selected in the states of switches SW31 and SW32 and outputs the added audio signals. An output 23 (BUS 3) adds only the audio signals of inputs that are dynamically selected in the states of switches SW1 to SW4 between all prescribed inputs and outputs the added signals. A BUS 4 configures an output system of a full assign system capable of adding additional inputs. A pattern switch 5 controls the switches SW1 to SW4, SW31 and SW32. COPYRIGHT: (C)2004,JPO
