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.

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.
