Patent ID: 7933422

Claim:
A mixing system including an operation panel, a plurality of input channels, a plurality of mixing buses for mixing output signals of individual ones of the input channels and a plurality of output channels provided in corresponding relation to said mixing buses, said operation panel comprising: an input channel section including faders for controlling attenuation rates of the individual input channels, ON/OFF switches for controlling ON/OFF states of the individual input channels, and channel selection switches for selecting any one of the input channels; a selected channel control section including an equalizer section having a plurality of controls for setting parameters of an equalizer for the one input channel selected via any one of said channel selection switches, a compressor section having a plurality of controls for setting parameters of a compressor for the selected one input channel, and an attenuation control for setting an input attenuation rate for the selected one input channel; a signal delivery control section including a plurality of level controls for controlling send levels, to said plurality of mixing buses, of the selected one input channel, and a plurality of ON/OFF switches for controlling ON/OFF states of signal delivery, to said plurality of mixing buses, of the selected one input channel; and a display for displaying a screen selected from among a plurality of screens for showing parameters of the selected one input channel, wherein said input channel section is positioned at a front row on said operation panel closest to a human operator position, and said display, said selected channel control section and said signal delivery control section are positioned at a second row on said operation panel further in distance from the human operator position than said first row, wherein said operation panel further comprises an operation mode selector for selecting one of a first operation mode and a second operation mode to set said signal delivery control section to the selected operation mode, wherein, when said first operation mode is selected, said level controls function as controllers for adjusting levels of signals to be supplied from the selected one input channel to individual ones of said mixing buses, while, when said second operation mode is selected, said level controls function as controllers for adjusting levels of individual signals to be outputted from said plurality of mixing buses via the corresponding output channels, and wherein, when said first operation mode is selected, said ON/OFF switches function as controllers for setting ON/OFF states of the signals to be supplied from the selected one input channel to the individual mixing buses, while, when said second operation mode is selected, said ON/OFF switches function as controllers for setting ON/OFF states of the signals to be outputted from said plurality of mixing buses via the corresponding output channels.
