Product Overview
The AM3A 3CH Class D Plate Amplifier delivers exceptional sound performance and efficiency for professional active speaker systems. With total output power of 1800W + 900W + 900W, it ensures powerful and balanced audio across low, mid, and high frequencies. Built-in DSP processing provides full control over EQ, crossover, limiter, and delay settings for precise system tuning. Its compact aluminum panel design ensures excellent heat dissipation and easy installation in powered speaker cabinets. Perfect for high-end PA, touring, and installation setups requiring high reliability and crystal-clear sound reproduction.
Key Features
1. High-Power Triple Channel Output
The AM3A offers three independent Class D amplifier channels—1800W for low frequencies and two 900W channels for mids and highs. This design ensures accurate power distribution and superior dynamic performance, ideal for tri-amp speaker systems and active full-range cabinets.
2. Advanced DSP Control System
Equipped with an integrated DSP board, the AM3A allows engineers to adjust EQ, crossover, phase, and limiter settings via PC software or front control panel. It ensures precise tuning, consistent performance, and easy adaptation for different venues or speaker designs.
3. Efficient Class D Technology
Using the latest switching power supply and Class D circuit, the AM3A achieves over 90% power efficiency while maintaining ultra-low distortion. The design minimizes heat and energy loss, making it suitable for continuous
operation in professional environments.
4. Intelligent Protection & Reliability
The amplifier includes multiple protection systems—over-voltage, over-temperature, DC, and short-circuit protection—ensuring long-term reliability. Its stable performance has been verified in continuous testing before shipping.
5. Compact Design for Easy Integration
Lightweight and compact, the AM3A fits perfectly into a variety of active speaker enclosures. The precision aluminum panel improves heat dissipation, while the plug-and-play connectors simplify system wiring and maintenance.
