Overview

What it is and how it fits the system.

The 4XDPS1200 (585033) is a constant-voltage, direct-output Class D amplifier for VARIODYN ONE voice-alarm applications, built on Class D modules with a Power Sharing feature. Each of its four channels can deliver 500 W at 100 V or 350 W at 70 V to the load. It runs from 115–250 V AC (±10 %) mains via an IEC connector, with an external 24 V DC backup supply for continued operation.

Technical overview

The 585033 is a 4-channel constant-voltage Class D amplifier from the VARIODYN ONE family, designed for direct speaker drive in voice-alarm systems. It delivers 500 W per channel at 100 V or 350 W at 70 V, utilising Power Sharing technology to optimise output across active channels. The unit operates from 115–250 V AC (±10%) via an IEC connector, with an external 24 V DC backup supply for mains failure resilience.

Audio performance includes <0.06% THD at 1 kHz, a 90 dB(A) signal-to-noise ratio, and >80 dB channel separation. It supports channel enable/disable and power-saving modes, and connects to VARIODYN ONE system components such as the GNP Controller and VARIODYN DI DOM modules for control, monitoring, and audio input. Compatible with industry-standard 100V speakers, it integrates into VARIODYN ONE voice-alarm installations via specified wiring detailed in the installation manual.
