Digital Mixer Dual Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital mixers lack the capability to simultaneously display, operate, or change multiple channels or parameters, limiting user efficiency in audio signal processing.
Innovation Solution
A digital mixer with two displays that allows users to switch between modes: one mode for displaying different audio signals on each display, and another mode for displaying the same audio signal's parameters on both displays, enabling simultaneous operation and parameter setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single display screen is used to show parameter setting screens, then the device structure is simple, but multiple parameters or channels cannot be operated simultaneously
Solution Approach 1:
The display system is segmented into multiple independent display screens (first display and second display), allowing different parameter setting screens to be displayed simultaneously on different screens. This enables users to operate multiple parameters or channels at the same time without switching between screens, directly resolving the contradiction between simultaneous operation capability and display structure complexity.
2Productivity
If parameter setting screens are switched sequentially on a single display, then the display structure is simple, but user efficiency decreases due to constant screen switching
Solution Approach 1:
The solution transitions from a single-dimensional display (one screen showing one parameter at a time) to a multi-dimensional display system where multiple parameter setting screens are displayed simultaneously across multiple screens. This dimensional expansion eliminates the need for sequential switching, allowing users to access and operate multiple parameters concurrently, thereby improving user efficiency and eliminating time loss associated with screen switching.
3Adaptability or versatility
If multiple displays are provided to enable simultaneous display of multiple parameters, then simultaneous operation is enabled, but the physical size of the mixer increases
Solution Approach 1:
Each display screen is designed to be multi-functional, capable of displaying different types of parameter setting screens (input level, equalizing, compressor, etc.) depending on the selected mode. This universality allows the system to provide simultaneous display of multiple parameters without requiring dedicated displays for each parameter type, thereby enabling simultaneous operation capability while controlling the increase in physical size.

AI summary
A digital mixer is disclosed having a plurality of displays and which applies a mixing process on an audio signal. The digital mixer includes an input interface, one or more processors, an output interface, at least a first display and a second display, and an operator. The operator includes a mode switching button for switching between a first mode and a second mode. The one or more processors are configured to cause parameter setting screens of audio signals of different channels to be displayed respectively on the first display and the second display when the mode switching button is set to the first mode, and cause different parameter setting screens of an audio signal of a single channel to be displayed respectively on the first display and the second display when the mode switching button is set to the second mode.
