The Midas DL351 is a modular digital stage box system designed to offer maximum flexibility and scalability as the remote I/O hub for compatible digital mixing consoles. Unlike fixed-configuration stage boxes, its core chassis serves as an empty shell that can be populated with a variety of specialized input and output cards, allowing sound engineers and system integrators to build a custom-tailored analog interface precisely suited to the needs of any production. This modular approach enables the creation of a stage box with a unique blend of microphone preamplifiers, line inputs, and analog outputs, making it an ideal solution for complex touring productions, large installed systems, or any application where standard I/O counts and types are insufficient.

The system's foundation is its robust digital audio network, centered on the AES50 protocol, which transmits all audio channels with low latency and high fidelity over standard shielded Cat-5e cable to the mixing console. Available card options typically include modules housing multiple channels of the renowned Midas discrete microphone preamplifiers, known for their sonic transparency and headroom, as well as line-level input and output cards. This allows users to configure, for example, a box with 32 channels of premium mic preamps, or a mix of 16 mic pres and 16 dedicated line-level returns for external processors. All parameters of the installed preamps—including gain, phantom power, and filters—are remotely controllable from the console.

Housed in a durable rack-mount chassis built for the rigors of the road, the DL351 emphasizes reliability and serviceability. Cards are hot-swappable, facilitating quick replacement or reconfiguration without taking the entire system offline. The unit features redundant AES50 network ports for creating daisy-chained or redundant ring network topologies, enhancing system stability for mission-critical live performances. Power can be supplied via the AES50 link from a console with a dedicated power supply or locally. By providing a fully customizable, high-performance, and network-efficient stagebox solution, the Midas DL351 empowers audio professionals to design an I/O system that perfectly matches their specific technical and creative requirements.
