Product Overview
The AM252 Plate Amplifier is a compact high-quality Class D DSP module designed for small active speaker systems. With an output of 2 × 250 W at 8 Ω (or AM251 250W + 100W option), it offers full-range performance ideal for 6.5″–10″ cabinets. Embedded DSP offers EQ, crossover, limiter, delay and polarity control to fine-tune sound. It delivers clean, professional audio. Lightweight and efficient, the AM252 module makes it easy to convert passive speakers into active units, or to build compact powered cabinets with full DSP control.
Key Features & Advantages
1. Reliable 250 W × 2 Output
The amplifier provides 2 × 250 W RMS into 8 Ω (with alternate AM251 250W + 100W option), enabling true full-range performance in small loudspeakers. As a plate amplifier module, it lets compact active cabinets deliver rich sound without bulky external amps.
2. Advanced DSP Integrated Control
On-board DSP supports EQ, crossover, delay, limiter, polarity, mute and mixer functions. With USB or RS-485 connectivity, you can precisely control your speaker system—making it an effective DSP plate amplifier for modern active applications.
3. Professional Audio Quality
The AM252 offers ultra-clean audio performance. It also separates channels, ensuring minimal crosstalk—essential for clear stereo imaging in small active speakers.
4. Compact Design & Global Compatibility
Measuring just 248×142×70mm and weighing about 1.6kg, this unit is ideal for retrofitting passive cabinets or OEM builds. With dual voltage support (90-135V or 180-265V), it works internationally—highlighting its versatility as a compact active speaker amplifier.
5. Comprehensive Protection for Longevity
Built-in protections include short circuit, DC, over-voltage, under-voltage, over-current and over-temperature. This ensures the plate amplifier remains stable and reliable in real-world use, protecting both the module and connected drivers.
Application Scenarios
• Small Powered Cabinets — Ideal for 6.5″ or 8″ two-way full-range active speaker builds, offering all the amplification and DSP control in one compact module.
• Retrofit Passive Speakers — Upgrade your existing passive loudspeakers by installing the AM252 plate amp module to convert them into modern active speakers with DSP tuning.
• Portable PA Systems — The lightweight module allows for compact, efficient portable PA speaker systems, suitable for mobile events, presentations or small venues.
• DIY Speaker Projects & OEM Builds — For audio manufacturers or hobbyists designing custom active loudspeakers, the AM252 offers a plug-and-play core amplifier + DSP solution, reducing development time and increasing reliability.
