Inter-M DPX-600D 2-Channel 600W Digital Power Amplifier

The Inter-M DPX-600D is a high-performance 2U digital power amplifier engineered for reliability and clarity in commercial sound and public address applications. Delivering 600W across two channels, the DPX-600D offers pristine audio reproduction, high signal-to-noise ratio, and a comprehensive suite of protection and monitoring features.

Built around a high-efficiency Class-D amplifier design with a robust SMPS power supply, it provides dependable performance even in demanding installations. In the event of a mains power failure, the DPX-600D automatically switches to DC 24V emergency backup operation, ensuring uninterrupted broadcasting—ideal for integration in emergency PA systems.

A key advantage is its intelligent protection system, safeguarding against overheating, over-input, output shorts, ground faults, reverse voltage, and more. Front-panel LEDs and a buzzer offer instant visual and audible status indication, enabling quick troubleshooting and system assurance.

The DPX-600D also includes a priority broadcast input, allowing emergency messages or alarms to override standard program audio automatically. Remote power control via contact closure and audio link capability further enhance system flexibility and integration potential.

The DPX-600D offers dual 600W channels for flexible multi-zone or stereo applications, while the DPX-600S delivers a single 600W output in a compact 1U design—ideal for single-zone systems requiring powerful, reliable performance with identical protection and redundancy features.

Typical applications include:

• Retail and franchise chains

• Hotels and hospitality venues

• Schools and training centres

• Commercial offices and business complexes

• Shopping centres and department stores

• Transport hubs and public facilities
