Abstract:
1. A mixer comprising: a plurality of input ports that input external device audio signals from external devices; a connection section that connects to said mixer via a communication network, wireless microphone receivers included in the external devices that supply wireless microphone receiver audio signals to the plurality of input ports, the wireless microphone receivers receiving wireless microphone audio signals from wireless microphones and outputting the received audio signals; an address and protocol input section that, for a particular one of the wireless microphone receivers for which communication via the communication network is to be established, inputs an Internet Protocol (IP) address unique to the particular wireless microphone receiver and a protocol of an application layer to be used for control data communication between said mixer and the particular wireless microphone receiver; control data reception section that establishes a communication path between said mixer and the particular wireless microphone receiver corresponding to the IP address input by said address and protocol input section and receives, from the particular wireless microphone receiver, control data possessed by the particular wireless microphone receiver in accordance with the protocol of the application layer input by said address and protocol input section; an input port setting section that sets correspondence relationship between the plurality of input ports and the wireless microphone receivers for which control data communication is to be performed by said control data reception section; a plurality of input channels each having a plurality of channel parameters, each of the input channels performing signal processing on an input audio signal in accordance with the channel parameters and then outputting the processed audio signal; an input patch section that defines correspondence relationship between the plurality of input ports and the plurality of input channels; a mixing section that selectively mixes the processed audio signals input via the plurality of input channels; an output section that outputs audio signals mixed by said mixer; a channel strip group including a plurality of channel strips each including at least a fader, any desired ones of the plurality of input channels being allocatable to each of the plurality of channel strips; a channel allocation section that allocates desired ones of the plurality of input channels to individual ones of the plurality of channel strips; and a display section that displays, individually for the input channels, the channel parameters related to the input channels allocated to the individual ones of the plurality of channel strips by said channel allocation section, wherein, when the input channel to be displayed on said display section is an input channel for inputting an audio signal of the input port corresponding to the particular wireless microphone receiver, said display section displays, in place of a part of the plurality of channel parameters, states of the particular wireless microphone receiver, including a state of the wireless microphone for which the particular wireless microphone receiver is currently receiving a current audio signal on the basis of the control data received by said control data reception section.
