What Makes AM133 Different

The AM133 is built as an all-in-one amplification and control core for modern active loudspeakers. Instead of relying on external processors and multiple amplifiers, it combines high-power dual-channel amplification with integrated DSP management, allowing speaker designers to create compact, reliable, and professionally tuned systems.

Designed for continuous operation, the AM133 maintains stable output even under high load conditions, making it suitable for touring systems, fixed installations, and OEM-powered cabinets.

Core Technology Highlights

Dual Power Architecture

Two independently controlled amplifier sections allow precise allocation of power between low-frequency and mid/high drivers. This structure is ideal for bi-amped cabinets, reducing crossover losses and improving overall system efficiency.

Integrated DSP Engine

The onboard DSP enables accurate tuning through gain control, crossover configuration, EQ, polarity, limiter, and system protection parameters. This ensures consistent performance across different cabinet designs and applications.

High-Efficiency Class D Platform

With efficiency levels reaching approximately 92%, the AM133 minimizes heat generation and energy loss. This allows designers to reduce enclosure size while maintaining reliable thermal performance.

Industrial-Grade Reliability

A complete protection framework safeguards both the amplifier and loudspeaker drivers during startup, overload, or abnormal operating conditions. The robust aluminum structure enhances durability in demanding professional environments.

Typical System Applications

Active Two-Way Loudspeakers

Powered Subwoofer Systems

Line Array & Column Array Modules

OEM & Custom Speaker Manufacturing

The AM133 serves as a ready-to-integrate amplification platform for manufacturers seeking faster development cycles, reduced component matching, and consistent sound performance across product lines.
