Description
X-DA2250EN is the Class-D amplifier and it is lighter, more stable, and high efficiency. The audio transmission is completely digitalized which makes it free from interference and easy to be controlled. It also has 24 VDC backup power supply conforming to international voice alarm standard which is the perfect choice for safety required applications.
When a shout circuit is detected in the main power supply circuit, the power will be automatically shut down. The backup power supply will then be enabled to replace the main one.
When a fault, self-protection or self-testing happens, its audio input fault port on the rear panel will short circuit and a fault signal will then be sent to the control unit in the network.
