The DB94 is a next-generation, compact MPX over IP Decoder engineered to deliver reliable and efficient audio transmission for professional FM broadcasting. Utilizing the purpose-built µMPX (MicroMPX) algorithm developed by Thimeo, the DB94 ensures high-quality audio reproduction with remarkably low network bandwidth starting from just 320 kbps. Designed specifically for FM MPX transport, µMPX preserves the integrity of the stereo signal and RDS data while significantly reducing IP requirements, making the DB94 ideal for applications over narrowband or public IP links.

Compact yet powerful, the DB94 fits seamlessly into any broadcast infrastructure. LED indicators on the front panel provide instant system status, while an intuitive HTML5-based web interface allows complete configuration and monitoring from any desktop or mobile browser. For added convenience and control flexibility, the device supports remote access via HTTPS, FTP, NMS, and SNMP protocols empowering engineers to manage systems from virtually anywhere.

Engineered with DEVA’s hallmark attention to detail and reliability, the DB94 delivers pristine audio quality thanks to top-grade DAC components and precision signal processing. It supports both Digital AES192 and Analog MPX outputs, ensuring compatibility with a wide range of FM transmitters and studio setups. Whether deployed at a single transmission point or within a larger network, the DB94 guarantees low-latency, uninterrupted signal decoding across all environments.

The DB94 stands as a testament to DEVA’s commitment to innovation and customer-driven design, offering an advanced, cost-effective solution for MPX over IP distribution. Its support for µMPX sets it apart as a future-ready decoder that meets the growing need for efficient, high-performance broadcast tools.

Choosing DEVA’s DB94 means choosing reliability, flexibility, and the confidence that comes with decades of expertise in broadcast technology.
