Supplier's note

  1. Technical Breakthroughs:

    • Class D Efficiency: Reduces power consumption by 30% compared to traditional Class AB amplifiers, lowering operational costs.
    • Wider Frequency Range (Pro Model): Extends bass response to 15Hz, ideal for subwoofers in live events.
    • Active Cooling (Pro Model): Maintains optimal performance in temperatures up to 50°C, outperforming passive designs by 40%.

  2. Version Selection Guide:

    • Base Model: Best for small venues or home studios prioritizing budget efficiency.
    • Advanced Model: Suitable for mid-sized events (e.g., bars, churches) needing full 1000W output and 4 channels.
    • Pro Model: Tailored for professional audio engineers requiring high channel density, extended frequency, and extreme reliability in outdoor festivals or theaters.

Example Use Case: The Pro Model’s 1200W output and 8 channels enable simultaneous control of main speakers, monitors, and subwoofers in a concert setup, while its active cooling ensures stable performance even during marathon events.
