Digital Mixer Channel-ON Operator Bus Routing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital mixers require complex and labor-intensive operations for human operators to confirm and set which input channels to send sounds to monitoring buses, as they need to manually navigate dedicated setting screens for each bus, making the process time-consuming and inefficient.
Innovation Solution
A digital mixer apparatus with bus selecting operators, channel-specific send operators, and channel-ON operators that display ON/OFF states of signal delivery, allowing users to easily confirm and set input channels for monitoring buses by operating the bus selecting operators, which changes the ON/OFF states and display settings without requiring new components, simplifying the operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional dedicated setting screens are used for each bus, then complete control over signal delivery is achieved, but operation complexity and time consumption increase significantly
Solution Approach 1:
The channel-ON operators are made multi-functional: they serve dual purposes as both channel power switches and as indicators for signal delivery status to the selected bus. This eliminates the need for separate dedicated setting screens and reduces operational complexity while maintaining complete control capability.
Solution Approach 2:
The invention merges the functions of channel power control and bus signal delivery indication into a single operator interface. By combining these functions, the system reduces the number of separate controls needed and simplifies the operator's workflow when configuring monitoring buses.
2Productivity
If manual navigation of dedicated setting screens is required for each bus, then precise control over channel-to-bus routing is achieved, but time consumption increases
Solution Approach 1:
The system performs preliminary action by automatically displaying the ON/OFF states of channel-to-bus signal delivery when a bus is selected, eliminating the need for operators to manually navigate through multiple setting screens. This preliminary display of status information speeds up the setup process while maintaining precise control.
Solution Approach 2:
The channel-ON operators provide immediate visual feedback about the signal delivery status to the selected bus. This feedback mechanism allows operators to quickly verify and adjust channel routing without time-consuming navigation through separate setting screens, thereby increasing productivity.
3Ease of operation
If independent setting of channel levels for monitoring is required, then accurate monitoring levels are achieved, but operational complexity increases
Solution Approach 1:
The channel-ON operators serve multiple functions: they control channel power, indicate signal delivery status to the selected bus, and can be used to adjust send levels. This multi-functionality reduces operational complexity by eliminating the need for separate independent setting procedures while maintaining accurate monitoring level control.

AI summary
While an AUX-bus selecting operator is being operated beyond a predetermined time period, displays of channel-ON operators, normally indicating ON/OFF states of corresponding input channels, indicate ON/OFF states of signal delivery from the input channels to the AUX bus. Thus, a user can readily confirm, with minimized operation, the ON/OFF states of the signal delivery from the input channels to the second bus. Operating any one of the channel-ON operators in this state can change the ON/OFF state of the signal delivery from the corresponding input channel to the AUX bus. Further, operating the AUX-bus selecting switch while keeping operating the layer operator, current fader settings of the input channels can be copied as delivery levels of signals from the input channels to the AUX bus. Because the delivery levels of sound signals from the input channels to the bus can be set using the fader settings of the input channels as initial values, time and labor necessary for the setting operation can be minimized.
