DETAILS

Reliable, high-performance digital PA amplification with advanced protection and AC/DC redundancy.

The DPX Series from Inter-M are a range of high-end digital PA amplifiers, engineered for dependable performance and great sound quality.

Building on the proven reliability of the Inter-M DPA series, the DPX range combines robust power output with comprehensive protection systems, intelligent monitoring, and flexible installation options.

Advanced Protection

The DPX Series is equipped with extensive protective and preventive circuitry to safeguard both the amplifier and connected speaker lines:

  • Reverse Voltage Protection – Detects reverse AC voltage on output lines during standby and blocks operation to prevent damage.

  • Ground Fault Protection – Automatically isolates the output when a ground fault is detected.

  • Output Short Protection – Channel-level short detection that immediately blocks affected outputs.

  • Over-Input Protection – Integrated limiter circuit protects the amplifier from excessive input signals (above 10V).

  • Voltage Error Protection – UVP (Under Voltage), OVP (Over Voltage), and OCP (Over Current) circuits ensure stable performance even in unstable power conditions.

  • Thermal Protection – Intelligent temperature monitoring with variable-speed fan control prevents overheating.

Clear front-panel LED indicators and an audible buzzer provide instant status feedback, allowing issues to be identified and resolved quickly in the field.

Built for Real-World Installations

Retaining the core strengths of the DPA platform, the DPX Series features:

  • AC/DC power redundancy (220–240V AC / 24V DC) for uninterrupted operation

  • Priority input for emergency paging integration

  • Remote control terminals for system flexibility
