H3-215 3-Channel Class D DSP Plate Amplifier with Ethernet – 1800W + 1800W + 900W at 4Ω
Product Overview
The H3-215 is a high-power 3-channel Class D plate amplifier module designed for active three-way loudspeakers and professional sound reinforcement systems.
It integrates a Class D amplifier board, switch-mode power supply, DSP processor, and Ethernet control module into one compact unit. At 4Ω, the three output channels deliver 1800W + 1800W + 900W, providing powerful and efficient amplification for low-, mid-, and high-frequency speaker drivers.
The integrated DSP supports comprehensive loudspeaker processing, including gain, delay, polarity, limiting, mixing, equalization, and crossover control. System parameters can be configured from a PC through USB, RS-485, or Ethernet.
Its compact plate-mounted design simplifies installation and makes the H3-215 suitable for active three-way line array speakers, touring systems, powered subwoofer-and-top configurations, rental equipment, and fixed professional audio installations.
