Product Description
The AM825A is a 2-channel Class D plate amplifier module designed for bi-amped full-range speakers and column array systems. Delivering 800W + 250W at 8Ω, this amplifier offers a perfect balance of power, precision, and reliability — making it ideal for compact PA systems or upgrading passive loudspeakers into active configurations.
Each channel of the AM825A is equipped with an independent DSP processor, allowing detailed control over crossover frequency, EQ parameters, delay, limiter, and gain. This flexibility enables professional engineers to fine-tune every aspect of the sound, ensuring smooth integration between low and high frequency drivers.
The amplifier also features USB and RS-485 connectivity, giving users full access to system settings and remote tuning through PC software.
Compact yet powerful, the AM825A integrates all the essential features of a modern active sound system — making it a smart solution for portable PA, installation, or OEM speaker manufacturing.
