Abstract:
1. A mixing console comprising: an input channel section having N input channels which control levels of one or more input audio signals and output the one or more level-controlled audio signals, wherein N is an integral number equal to or greater than one; M mixing buses which mix one or more level-controlled audio signals from said input channel section to output one or more mixed signals, wherein M is an integral number equal to or greater than one; an output channel section having M output channels which are supplied with the one or more mixed signals output from the M mixing buses; M talkback input sections provided at a stage preceding respective ones of the M output channels of said output channel section; a selection section which selects one or more of said M talkback input sections; and a talkback supply section to which a talkback signal is input, and which supplies the talkback signal to said talkback input sections, wherein, when the talkback signal is supplied at least to the talkback input section selected by said selection section, the talkback input section selected by said selection section attenuates an amplitude of the mixed signal supplied from a corresponding one of the M mixing buses, mixes the supplied talkback signal with the attenuated mixed signal to thereby generate a mixed output signal, and supplies the mixed output signal to a corresponding one of the M output channels, wherein each of said M talkback input sections includes: wherein the selected talkback input section selects the output signal of said attenuator as said attenuated mixed signal by said first switch and selects the talkback signal by said second switch to thereby output a signal obtained by mixing the signals selected by the first and second switches, and wherein each talkback input section not selected by said selection section from among the M talkback input sections selects the mixed signal supplied from the corresponding mixing bus by said first switch but does not select the talkback signal by said second switch, so that the talkback input section not selected by said selection section outputs only the mixed signal supplied from the corresponding mixing bus.
