The Midas DL371PRO9 is the central digital audio engine and router for the flagship PRO9 live sound mixing system, representing the pinnacle of Midas's digital console technology. This rack-mountable unit is the computational heart of the system, housing all digital signal processing (DSP), analog and digital I/O, and the proprietary HyperMAC audio networking infrastructure. Its formidable processing power, quantified at 31.6 Gigaflops, is dedicated to running the console's vast channel count, extensive dynamics processing, high-resolution equalization, and effects on every input and output simultaneously with ultra-low latency. This ensures that even the largest and most complex live productions can be mixed with the same headroom, clarity, and responsiveness as a high-end analog console.

A core innovation of the DL371PRO9 is its integrated HyperMAC router. This provides a high-bandwidth, deterministic audio network that connects the engine to multiple control surfaces (up to four with a PRO9 system) and remote I/O racks over a single fiber optic cable. HyperMAC carries all audio channels, control data, and communications bi-directionally, allowing surfaces to be positioned hundreds of meters from the stage racks without signal degradation. The system supports a massive I/O capacity, with the ability to handle hundreds of input and output channels at sampling rates up to 96 kHz. The engine itself is equipped with extensive local I/O, including analog microphone preamps, line outputs, and digital AES/EBU and MADI ports, providing immense flexibility for system integration.

Designed for mission-critical reliability, the DL371PRO9 features a modular, redundant architecture. It supports dual-redundant power supplies and can be configured with redundant DSP cards and network paths, ensuring uninterrupted operation. All components are hot-swappable, allowing for maintenance without taking the system offline. This engine is what enables the Midas PRO9 console to deliver its legendary sonic signature—the "Midas sound"—in a digital format, providing engineers with unparalleled sonic tools, system scalability, and absolute reliability for the world's most demanding live audio applications, from major concert tours to broadcast events.
