DPA2300/DPA2450/DPA2650/DPA2800 is a 1U 2-channel Class-D professional power amplifier that delivers powerful performance in a compact chassis. It features a high-efficiency switching power supply, precision gain control, and selectable output modes (Stereo / Parallel / Bridge) to suit different system setups. With balanced XLR inputs/outputs, Speakon connectors, and selectable input sensitivity (0.775V / 1.414V / 32dB), it ensures flexible connectivity. The unit is built with an aluminum alloy front panel and efficient front-to-rear airflow for reliable cooling, while its intelligent protection system guards against overload, short circuit, overheating, and more—ensuring stable and safe operation at all times.
