A8A-4 channel DSP digital power amplifier


  • Product Description
  • Usage: Drive 4 CM15s or 4 P10s;
    Energy Dynamic Analysis Technology: Independently and dynamically analyzes audio signal input, power output, frequency bands, and time segments. It calculates the accumulated heat of the treble and bass speakers over different durations and accurately calculates the power output distribution, allowing the speakers to deliver high-dynamic energy amplification for extended periods, ensuring stability and protecting the speaker units from damage.
    Dynamic Distortion Compensation Technology: The amplifier analyzes and receives the real-time online status of the current in the audio cable, feeding back the phase distortion and nonlinear distortion of the speaker. It performs subtle calculations to determine the optimal distortion compensation, significantly improving the speaker's performance and providing more precise refinement of the sound quality. This showcases new application areas and development trends for audio products.
