X-DA2250EN
High Efficiency Power Amplifier
with 24 VDC Backup Power Supply
• Two channel 250W efficiency Class-D amplifier
• Automatic protection
• Fault detection
• Effective ventilation using forced air cooling fan
• CE complied
• With 24 VDC backup power supply
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.
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.
The amplifier can work without main power
in emergency.

X-DA1500EN can receive audio signal from
XDCS2000/EN via Ethernet through the RJ45

FAULT DETECTION
X-DA1500EN can self-protect from overheat, over
current, over voltage and 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-DA1500EN 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.

X-ND100 (Digital Noise Detector) is used to detect ambient noise,
automatically calculate the noise SPL, and transmit the SPL data to
X-DCS3000. It is an important component tofulfill the function of automatic
volume control. While broadcasting, the sound is mixed with ambient noise.
In order to measure the noise SPL accurately, X-ND100 measures
broadcast signal from speaker lines, comparing with the signal from
microphone to get the actual noise data.
FEATURES AND BENEFITS
• Connect toX-DCS3000 by a pair of cables, through which fulfill
communication and power supply.
• Max. 5 noise detectors for each channel.
• Max. transmission distance is 1000m.
• Flush-mounting in ceiling.
• Currently collect broadcast signal and noise signal.
• Fire-proof ABS shell.
• Ideal for indoor installation.
