This is a Class D digital amplifier intended for commercial and industrial public address systems. Rack mount design in 1U type with rated power of 4*250W.Each channel supports both balanced and unbalanced line inputs. The balanced line output feeds another power amplifier while also ensuring that the signal is transmitted with less noise and over a longer distance. 70V and 100V speaker outputs make installation easier when selecting different speaker matchings. Clip, short circuit, high temperature, and overload are all part of the complete protection. There are indicators for power, signal, clip, protection, and temperature. This equipment can be referred to as a 4 channel mixer amplifier.
