Honeywell X-DA2250EN supports both balanced and unbalanced audio inputs as well as receives audio signals from X-DCS3000 via Ethernet through the RJ45 standard port. X-DA2250EN can also self-protect from overheating, over current, over-voltage, and under voltage. For example, when the internal temperature reaches its critical limit, the overheating protection circuit will shut down the power amplification module and activate the protection indicator light on the front panel. Moreover, it can detect power supply errors automatically during operation. The built-in fuse will provide overcurrent protection to the main power supply.

The front panel of the X-DA2250EN is made of UL94V-0 fireproof 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 case of emergencies.
