Fault Detection

X-DA1500 can self-protect fromoverheat, overcurrent, overvoltage

andunder voltage. For example, when theinternal temperature

reaches itscritical limit, the over-heat protectioncircuit will shut

down the power amplification module and activate theprotection

indicator light on the frontpanel X-DA1500 can detect power

supplyerrors automatically during operation.The built-in fuse

will provide overcurrent protection to the mainpower supply.

When a shout circuit is detected in themain power supply circuit,

the powerwill be automatically shut down. Thebackup power supply

will then beenabled to replace the main one.

When a fault, self-protection orself-testing happens, its audio inputfault

port on the rear panel will shortcircuit and a fault signalwill then besent 

to the control unit in the network.

equippedfor heat exhaustion so that themachine can maintain high

workingefficiency.
