Inter-M - DPN-240S
Digital Amplifier Dante 1 x 240W, EN54-16 for EVA Matrix
Product Description
The Inter-M DPN-240S is a high-performance 1 x 240W RMS Class D network amplifier specifically designed for EN54-16 certified voice alarm systems, integrating seamlessly with the EVAMATRIX platform.
Engineered for mission-critical public address and evacuation applications, it supports 70V/100V constant voltage speaker lines with galvanic isolation to ensure safe, high-fidelity audio delivery.
Built on Dante and AES67 IP networking, the DPN-240S offers full audio and control redundancy via dual RJ45 ports and enables advanced DSP-based zone control, including EQ and volume adjustments via the EVAMATRIX web interface. It also features a dynamic backup amplifier input, dual A/B speaker outputs, and dry contact and UGA inputs for local alarm triggering and third-party integration.
All signal paths and faults are fully supervised with SNMP V2c monitoring, while robust cybersecurity includes HTTPS, TLS1.2, AES-256, and ECC encryption. With ultra-low THD (<0.45%), >91dB signal-to-noise ratio, and 20Hz–20kHz bandwidth, the DPN-240S ensures professional-grade audio.
The compact 1U rackmount unit includes OLED display, local audio input, and visual/audio fault indication, making it ideal for decentralised voice alarm deployments.
