X-DA2250 High Efficiency Power Amplifier
provides amplification for audio signal delivered by
high power loudspeakers that are connected to
X-618 Digital Public Address and Voice Alarm
System.X-DA2250 is reliable, efficient and light in
weight.

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.
VOLUME CONTROL
When HN-D32N Noise Detector is installed,
X-DA2250 can adjust volume according to the
ambient noise automatically to ensure high sound
intelligibility.
