<P>PROBLEM TO BE SOLVED: To provide an analog sound monitoring apparatus and method for realizing flexible operations by varying an interconnection relation between input output ports and a mix ratio by external computer control or the like. <P>SOLUTION: The analog sound monitoring apparatus is provided with: a varying section 4 acting like a varying means to change a signal level of each desired channel as to a sound signal received by each channel from an input side and configured with a variable resistor (element) 40 being an externally controllable signal level adjustment unit provided respectively to each channel of a signal bus 3 from which a source is received; and a router section 5 and adders 6 acting like adder means for selecting, summing sound signals of each channel via the variable resistor 40 by a desired combination and outputting the sum to an output side. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
