AM155 2 Channel 1500W DSP Plate Amplifier Power Module

Product Overview

The AM155 is a high-performance 2-channel Class D plate amplifier designed for active speaker systems. Delivering 1800W + 700W RMS output, it provides clean, stable power for both subwoofers and full-range drivers. With advanced switching technology and low heat dissipation, this amplifier ensures reliable performance even under continuous load. Featuring balanced XLR input, comprehensive protection circuits, and a compact aluminum heatsink, the AM155 is ideal for professional PA systems, stage monitors, and club installations. Built with precision engineering and premium components, it ensures long-lasting durability and consistent sound clarity.

Key Features & Advantages

1. Dual-Channel High Power Output

Equipped with two independent channels (1800W for sub and 700W for mid/high), the AM155 provides flexible power distribution, ideal for bi-amped active speakers or compact PA setups. High efficiency MOSFET technology ensures strong, distortion-free performance across all frequencies.

2. Efficient Class D Technology

Using advanced Class D circuitry, the amplifier achieves up to 92% efficiency, reducing energy loss and heat buildup. This makes it perfect for compact enclosures where space and cooling are critical, while maintaining precise transient response and dynamic headroom.

3. Reliable Protection System

Built-in thermal, short-circuit, overcurrent, and DC protection keep the system stable under demanding conditions. The AM155 also features soft start and clip limiter functions to protect both the amplifier and speakers during power-up and heavy load operation.

4. Compact, Rugged Design

Constructed with a heavy-duty aluminum heat sink and solid chassis, the AM155 delivers excellent heat dissipation and durability. Its modular design allows for easy integration into powered cabinets or OEM speaker systems.

Application Scenarios

• Bi-Amp Active Loudspeakers

Use AM155 in a speaker that splits bass and mid/high drivers. Its dual outputs let you power the woofer and top section independently, with the DSP adjusting crossover and EQ for optimal crossover between channels.

• Active Subwoofer + Satellite Systems

Power your sub with the high-power channel and feed the weaker channel to drive a passive satellite speaker. This subwoofer plate amplifier module simplifies system design and reduces external amps.

• Line Array & Column Speakers

In array or column systems, AM155 provides flexibility to bi-amp critical elements. DSP control ensures fine tuning across vertical coverage, making it a reliable DSP plate amplifier for active line arrays.

• Custom Speaker & OEM Integration

For speaker manufacturers or custom builds, AM155 provides a turnkey DSP + dual-channel power solution. It speeds up development, ensures matched performance, and simplifies design of powered speaker systems.
