Description

Honeywell X-DA4125-B High Efficiency Power Amplifier provides amplification for audio signal delivered by high power loudspeakers that are connected to X-618 Digital Public Address and Voice Alarm System. Honeywell X-DA4125-B is reliable, efficient and light in weight.

Features

Input/Output

X-DA4125-B supports both balance 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-B can receive audio signal from X-DCS2000/EN via Ethernet through the RJ45 standard port.

Fault Detection

X-DA4125-B 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-DA4125-B 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 circuit, the power will be automatically shut down. The backup power will then be enabled to replaced 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.

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.

Volume Control

When HN-D32N Noise Detector is installed, X-DA4125-B can adjust volume according to the ambient noise automatically to ensure high sound intelligibility.
