Engineering Contradiction Analysis
1Reliability
If a speaker processor with multiple adjustable components (equalizer, delay device, etc.) is provided, then optimal signal processing for various speaker systems can be achieved, but it becomes difficult for poorly-skilled users to set the signal path and parameter values
Solution Approach 1:
The system pre-prepares multiple configuration data sets that contain pre-optimized parameter values for equalizers, delay devices, and other signal processing components. Each configuration data set corresponds to a specific amplifier mode (e.g., full-range, subwoofer, bi-amp). When a user selects an amplifier mode, the corresponding pre-configured data set is automatically applied, eliminating the need for users to manually adjust numerous parameters while still achieving optimal signal processing for the selected speaker system type
Solution Approach 2:
The system provides different configuration data sets with varying parameter settings tailored to different amplifier modes and speaker system characteristics. By changing the configuration data set based on the selected amplifier mode, the system automatically adapts the signal processing parameters (equalization curves, delay times, crossover frequencies) to match the specific requirements of full-range systems, subwoofers, bi-amp configurations, or other speaker types, thus resolving the contradiction between optimization and ease of use
2Adaptability or versatility
If multiple configuration data sets are prepared for different amplifier modes, then settings suitable for various speaker systems can be applied automatically, but the device complexity increases
Solution Approach 1:
The audio equipment is designed with a universal configuration system that can handle multiple amplifier modes (full-range, subwoofer, bi-amp, and other speaker system types) through a single integrated architecture. The system uses a unified interface where users simply select the amplifier mode, and the corresponding configuration data set is automatically applied. This multi-functional design allows the same device to adapt to various speaker system types without requiring separate processing paths or complex manual configuration for each mode, thus achieving high adaptability while maintaining relatively simple device structure
