Features

INPUT/OUTPUT

X-DA2250 supports both balanced and

unbalanced audio inputs.To receive unbalanced

audio inputs, simply connect the ground port with

the negative input port  to the rear panel.

X-DA2250 can receive audio signal from

X-DCS2000/EN via Ethernet through the RJ45

standard port.

FAULT DETECTION

X-DA2250 can self-protect from overheat,

over current,over voltageand under voltage.  For

example, when the internal temperature reaches

its critical limit, the overheat protection circuit will

shut down the power amplification module and

activate the protection indicator light on the front

panel.

X-DA2250 can detect power supply errors

automatically during operation. The built-in fuse

will provide over current protection to the main

power supply.

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.

SAFETY

The device adopts lightweight design.The front

panel is made of UL94V-0 fire proof ABS material,

protecting the machine under extreme conditions.

A cooling fan is equipped for heat exhaustion so

that the machine can maintain high working

efficiency.
