Introduction
This Class D digital amplifier DA2250is a 2 channel digital amplifier, which designed for commercial and industrial public address applications. Rack mount of this amp digital design in 1U type and rated power is 2*125W/250W/500W.
DA2250 is also called two channel amplifier, both balanced and unbalanced line inputs are available for each channel. Balanced line output feeds to another power amplifier as well as secures the signal transmission is less noise and longer distance. 70V, 100V speaker outputs are convenient for installation when selection different speaker matching. Complete protection of this Class D digital amplifier include clip, short circuit, high temp and overload. With indications for power, signal, clip, protection and temperature. This product can be called 2 channel power amp or 2 channel 70v amplifier.
