FAULT DETECTION

X-DA4125EN 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-DA4125EN 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 por

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. The amplifier can work without main power in emergency.

VOLUME CONTROL

When HN-D32N Noise Detector is installed, X-DA4125EN can adjust volume

according to the ambient noise automatically to ensure high sound intelligibility.
