FEATURES

Input/ Output

X-DA4125 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-DA4125 can detect power supply errors automatically during

operation.The built-in fuse will provide overcurrent 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 back up power

supply will then be enabled to replace the main one.

X-DA4125 can receive audio signal from XDCS2000/ EN via Ethernet

through the RJ45 standard port.

Fault Detection

X-DA4125 can self -protect from overheat, overcurrent, overvoltage

and undervoltage. For example, when the internal temperature reaches

its critical limit, the over-heat protection circuit will shut down the

power amplification module and activate the protection indicator light

on the front panel.

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.

• Four channel 125W hight efficiency Class-D amplifier

• Automatic protection

• Fault detection

• Effective ventilation using forced air cooling fan

Safety

The device adopts lightweight design. The front panel is made of UL94V-0

fire proof ABS material, protecting the machine underextreme conditions.

A cooling fan is equipped for heat exhaustion so that the machine can

maintain high working effi ciency.

Volume Control

When HN-D32N Noise Detector is installed, X-DA can adjust volume according

to the ambient noise automatically to ensure high sound intelligibility.

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.

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.
