Q: What are the core functions and technical advantages of Digital Audio Processor?
A: Matrix routing capability: supports any combination of input signals to be assigned to output channels to meet multi-zone audio control requirements (such as conference room partition sound reinforcement);
Signal processing module: integrates DSP algorithms such as equalizer, compressor, delay and electronic frequency division to dynamically optimize the signal;
Network control: supports remote configuration of parameters via Ethernet or dedicated software to improve system deployment efficiency;
High compatibility: supports mixed access of analog input and digital audio protocols (such as Dante) to adapt to complex audio and video system architecture.
Q: In what application scenarios does Digital Audio Processor have typical value?
A: Small and medium-sized multi-functional halls: distribute input signals such as multi-channel microphones and background music to the main sound reinforcement, supplementary speakers and recording equipment;
Education and training venues: realize classroom audio partition control, such as directional output of lecturer audio to a specific area;
Commercial exhibition space: dynamically switch background music or guided voice in different exhibition areas while maintaining low latency and high-fidelity output;
Emergency broadcast system: ensure that emergency broadcast signals cover all output channels through priority routing function.
