The digital audio processor features a built-in professional audio processing chip, utilizing a single professional audio processor (8-core, 6T high computing power), and incorporates industry-leading audio signal processing algorithms, such as the low-latency ClearVoice AI algorithm, adaptive sound field control technology, multimodal AI noise reduction system, spatial sound field modeling technology, a dual-engine architecture combining traditional audio processing with deep AI algorithms, and dynamic beamforming. 

These features effectively enhance the quality of voice interaction and deliver outstanding audio processing performance; It supports both analog and network audio signal transmission and processing, integrates a 4 × 100W power amplifier, and incorporates the industry-leading 5A audio preprocessing algorithm, effectively improving the quality of voice amplification and interaction; it supports connection with large microphone arrays for flexible and diverse application scenarios, allowing multiple units to be installed and used simultaneously, with users able to manage and control the devices centrally via PC debugging software. 

It supports multi-channel analog and network audio output and processing, making it suitable for video conference rooms, seminar rooms, and university teaching environments. A built-in Dante module enables network audio transmission. Equipped with proprietary advanced algorithms, it automatically adapts to various scenarios, ensuring clear and highly accurate voice reproduction whether for local sound reinforcement or output to remote terminals.
