Description
DSPPA DA4250 - Class D digital amplifier, 4x250W, 100V
The DSPPA DA4250 is a 4-channel Class D digital amplifier delivering 4x250W RMS output, designed for professional public address systems in commercial, educational, and industrial environments. It offers high efficiency and flexible configuration with real-time switchable 70V/100V output.
The amplifier features balanced, unbalanced, and priority line inputs, as well as balanced line outputs, all using HT-3.81 Phoenix connectors. DA4250 includes full protection against clipping, short circuit, overheating, and overload. LED indicators provide real-time feedback on power, signal, clipping, protection, and output voltage mode.
With active power factor correction (PFC), temperature-controlled fan speed, and voltage limit circuitry, the DA4250 ensures stable and safe operation under all conditions.
