Q: What are the core functions and technical advantages of Digital Sound Processor DSP?
A: The core function of the device is to support full matrix mixing routing with 12 audio inputs and 12 outputs, and realize signal distribution, gain adjustment and sound effect processing through high-precision DSP chips. Its technical advantages include:
Flexible routing configuration: allows any input signal to be distributed to a specified output channel, and supports independent sound reinforcement in multiple areas;
Intelligent audio processing: integrates adaptive feedback suppression (AFC), echo cancellation (AEC), automatic gain control (AGC) and other algorithms to ensure voice clarity;
Highly integrated design: some models have built-in wireless microphone receiving modules, power amplifiers and network transmission functions to simplify system construction;
Professional sound quality: supports 24bit/48kHz sampling rate, combined with 54dB microphone gain amplification, to meet high-fidelity sound reinforcement needs.
