Abstract

In an audio signal processing system, a plurality of signal processing units are connected to a transmission line. Each signal processing unit has a plurality of channels for applying a signal process to audio signals inputted thereto and outputting the audio signals to the transmission line after the signal process is applied. A control unit is connected to the transmission line for operating a target channel belonging to one of the signal processing units by transmitting a control signal to the one signal processing unit through the transmission line. The control unit has a plurality of color pallets which are different from each other and which are previously selected in correspondence to the plurality of the signal processing units. When the control unit detects an instruction to display an operation screen of the target channel, the control unit performs a process of rendering the operation screen of the target channel using the color pallet corresponding to the signal processing unit to which the target channel belongs, such that a background color of the operation screen of the target channel displayed on a display part of the control unit is different from a background color of an operation screen of another channel belonging to another signal processing unit.

Claims

1. An audio signal processing system comprising:

a transmission line that transmits a control signal and an audio signal;

a plurality of signal processing units that are connected to the transmission line, each signal processing unit having a plurality of channels for applying a signal process to audio signals inputted thereto and outputting the audio signals to the transmission line after the signal process is applied; and

a control unit that is connected to the transmission line for operating a target channel belonging to one of the signal processing units by transmitting a control signal to said one signal processing unit through the transmission line, the control unit having a display part and a plurality of color pallets which are different from each other and which are previously selected in correspondence to the plurality of the signal processing units for use with the display part, wherein

when the control unit detects an instruction to display an operation screen of the target channel, the control unit performs a process of rendering the operation screen of the target channel on the display part with using the color pallet corresponding to the signal processing unit to which the target channel belongs, such that a background color of the operation screen of the target channel displayed on the display part of the control unit is different from a background color of an operation screen of another channel belonging to another signal processing unit.

2. The audio signal processing system according to claim 1, wherein the operation screen contains an image of a knob or button for operating the target channel over the background color of the operation screen, and a color of the image of the knob or button is set invariable although the background color of the operation screen is changed according to the color pallet of the signal processing unit to which the target channel belongs.

3. The audio signal processing system according to claim 1, wherein the operation screen contains a common area over the background color of the operating screen, and a color of the common area is set common among the plurality of the signal processing units although the different color pallets are selected to the different signal processing units.

4. The audio signal processing system according to claim 1, wherein the plurality of the signal processing units include an external signal processing unit arranged separately from the control unit, and an internal signal processing unit integrated into the control unit.

5. An audio signal processing system comprising:

a transmission line that transmits a control signal and an audio signal;

a plurality of signal processing units that are connected to the transmission line, each signal processing unit having a plurality of channels for applying a signal process to audio signals inputted thereto and outputting the audio signals to the transmission line after the signal process is applied; and

a control unit that is connected to the transmission line for operating one or more channels belonging to one or more signal processing units by transmitting thereto control signals through the transmission line, the control unit having a display part and a plurality of color pallets which are different from each other and which are previously selected in correspondence to the plurality of the signal processing units for use with the display part, wherein when the control unit detects an instruction to display an operation screen on the display part for operating target channels belonging to different signal processing units, the control unit performs a process of rendering the target channels in the operation screen with using different color pallets corresponding to the different signal processing units to which the target channels belong, such that background colors of target channels belonging to different signal processing units are made different when all of the target channels are displayed on the display part of the control unit.

6. The audio signal processing system according to claim 5, wherein the operation screen contains an image of a knob or button for each of the target channels, and a color of the image of the knob or button of all the target channels is invariable although the background color of the target channels is made different.

7. The audio signal processing system according to claim 5, wherein the operation screen contains a common area in each of the target channels, and a color of the common area is set common among the target channels although different color pallets are selected to the different signal processing units.

8. The audio signal processing system according to claim 5, wherein the plurality of the signal processing units include an external signal processing unit arranged separately from the control unit, and an internal signal processing unit integrated into the control unit.
