4-Channel Power Amplifiers

AMP-A4-60/120/250/350

 

To amplify four independent audio signals via voltage and power amplification with independent volume adjustment, boosting signals to drive speakers and enabling flexible audio system setup. Ideal for stable sound reinforcement scenarios.

 

FEATURES

  • Supports dual systems (100V/70V constant voltage and 4–16Ω impedance) for versatile use.
  • Offers scalable power options (4×60W/120W/250W/350W) to adapt from classrooms to large venues needing reliable sound.
  • Enables precise zone control with independent channel volume adjustments for multi-area PA systems.
  • Ensures robust protection against overvoltage, overcurrent, short circuits, and overheating for harsh environments.
