Power Amplifier

The Inter-M DPX-1200S is a robust single-channel, 1200W Class-D digital amplifier engineered to deliver exceptional performance in large-scale public address and background music systems. Built with uncompromising reliability, the DPX-1200S combines high efficiency, advanced protection circuitry, and redundant AC/DC power operation, making it an ideal solution for mission-critical audio environments.

One of its defining features is the dual AC/DC power redundancy, enabling the amplifier to continue operation seamlessly via a 24V DC backup supply in the event of mains failure. This guarantees that emergency broadcast messages remain active under all circumstances.

The amplifier also supports a priority broadcast function, ensuring that alarms and emergency announcements override all other inputs for maximum safety compliance. Additionally, the comprehensive protection system safeguards against overheating, output short-circuits, reverse voltage, ground faults, and over-input errors, protecting both the amplifier and connected loudspeakers.

With its status LED indicators and optional buzzer alert, the DPX-1200S provides instant feedback on operational status and fault conditions. Offering clean, reliable power and flexible system integration, this amplifier is a trusted choice for engineers, installers, and facility managers working on large distributed audio systems.
