DA2125

DSPPA DA2125 - Class D digital amplifier, 2x120W, 100V

The DSPPA DA2125 is a 2-channel Class D digital amplifier designed for commercial and industrial public address systems. It delivers 2x120W RMS output and supports both 70V and 100V speaker lines, offering flexibility for various installation scenarios. The 1U rack-mount design ensures easy integration into 19" equipment racks.

Each channel supports both balanced and unbalanced line inputs, while the balanced line output allows signal transmission to another amplifier with reduced noise and extended range. The DA2125 includes comprehensive protection features against clipping, short circuit, overheating, and overload. LED indicators provide real-time feedback on power, signal, clipping, protection, and temperature status.
