DA8250 Digital Amplifier

Features:

● Touch screen design, user-friendly.
● 9 channels: 8 main amplifiers, 1 standby amplifier.
● Active/standby switching function: 8 main channels can use their respective main amplifiers, and they can also automatically/manually/remotely invoke standby power amplifier.
● Each amplifier channel has independent input and output interfaces, and one input corresponds to one output.
● Each amplifier can independently adjust the volume, the volume adjustment can be performed by the machine and remotely.
● High power switching design, with protection of over voltage, over current, high temperature, and short circuit.
● Status, volume, temperature and other operating parameters of this power amplifier can be displayed on LCD screen or remote host.
● 0 ~ 100V constant voltage output.
● Each module supports hot swap.
● A remote control host can connect and control multiple power amplifiers at the same time.
● With a communication interface, you can cascade multiple amplifiers.

The DA8250 device is an eight-master-one-standby-amplifier that integrates eight power amplifier modules and a sub-module and can control eight broadcast intervals. When one of the sections fails, the standby channel can also be used to continue broadcasting.
