                            Professional Class-D Four Channel Power Amplifier 
CX4.4
Description:
The professional sound range digital class-d amplifier is designed with switching power technology, whose advantages are without transformer for less heat generation and long life span. Moreover, higher efficiency of more than 85% could help to decrease the power electricity consumption by green environment protection. Special power circuit design of PWM to ensure the world first level natural cooling system with additional four fans.
The 19” rack mount design is suitable for universal permanent installation of any sound reinforcement system. The digital Class-D technology also bring the lighter amplifier of less rack space consumption into true, so it is very useful and cost-effective amplifier for installer and system contractor.
The rated power output of this amplifier is 4×400W, so it is enough for most of the meeting room, small stadium, bar, theme park and train station indoor and outdoor sound system, capacity of maximum connection of eight professional sound low impedance loudspeakers.
