Product Overview
The AM450 Plate Amplifier is a compact, high-efficiency Class D DSP module tailor-made for active speakers and powered cabinets. It integrates a switch-mode power supply and a Class D output stage, offering up to 450 W into 8 Ω (500 W into 4 Ω). With a built-in DSP engine, dual RS-485 interfaces for multiple control, and a slim chassis design, the AM450 is ideal for modern, intelligent loudspeaker systems. Its low distortion (< 0.1 % THD+N), wide 20 Hz–20 kHz frequency response, and robust protections (short, over-voltage, over-temperature) make it a reliable core for pro audio applications.
Key Features & Advantages
1. High Efficiency & Compact Design
The AM450’s Class D architecture delivers outstanding power output while consuming minimal energy. Its compact plate amplifier form factor (e.g. 332×142×70 mm, ≈1.7 kg) allows seamless integration into speaker enclosures, making it ideal as a built-in DSP plate amplifier for space-sensitive applications.
2. DSP & Remote Control Capabilities
Embedded DSP allows crossover, EQ, delay, limiter and protection functions. Dual RS-485 ports support remote monitoring and control, making the amp module ideal for smart speaker systems and networked audio installations. These features elevate it beyond a standard Class D amplifier module.
3. Robust Protection & Audio Fidelity
The AM450 includes multi-level safeguards: short circuit, DC protection, over-voltage, under-voltage, over-current, and over-temperature protection.
4. Voltage Versatility & Connectivity
Supports wide input voltage ranges (90–135 V or 180–265 V), making it usable globally. it as a versatile Class D amplifier module suitable for different markets.
5. Scalable Channel Options
While AM450 is a single-channel plate amplifier, the Ascsonic Audio supports multi-channel variants (2-channel, 3-channel) under the same design, giving you room to scale your powered speaker product lineup with consistent DSP and performance.
Application Scenarios
• Powered Loudspeaker Enclosures
Install the AM450 DSP plate amplifier module inside active full range speakers. Its slim profile and robust output make it a perfect audio engine for pro floor monitors, line arrays, or satellite speakers.
• Portable PA / Rental Systems
Its light weight and energy efficiency mean you can build compact, road-worthy powered speakers for events, DJ systems, or mobile sound hire setups, without sacrificing reliability or sonic fidelity.
• Installation Sound Systems
In fixed installations (houses of worship, clubs, conference halls), the AM450 plate amplifier allows discreet installation behind grills, inside cabinets, or built into ceiling speakers — while enabling remote DSP tuning and monitoring.
• Custom DIY Speaker Projects
For enthusiasts or OEMs building custom active speaker solutions, the AM450 module offers a plug-and-play amplifier + DSP core that accelerates development while giving professional-grade performance.
