The MIDAS DL444 is a modular analog interface card designed for installation in the DL431 expansion frame, extending the analog input and output capacity of compatible MIDAS digital consoles like the Heritage-D series. This card is specifically engineered to provide eight channels of high-quality analog connectivity, each featuring a discrete MIDAS microphone preamplifier on the input side, delivering the same sonic transparency, musicality, and headroom for which MIDAS analog consoles are renowned. The inputs accept both microphone and line-level signals via a robust, multi-pin "D-type" connector (typically a 25-pin D-sub), which is wired to breakout cables that terminate in standard XLR or TRS jacks for connection to sources on stage or in the rack. This consolidated connector approach allows for clean, high-density patching in permanent installations or within equipment racks.

On the output side, the card provides eight channels of balanced analog line-level output, also accessible via a second D-type connector. This makes the DL444 a balanced 8-in/8-out analog expansion module that seamlessly integrates into the console's digital patchbay. All eight microphone preamplifiers are fully remote-controllable from the console's surface, with software access to gain, phantom power (+48V), polarity reverse, and high-pass filter settings for each channel. This allows front-of-house engineers to maintain complete control over the analog stage sound as if the preamps were built directly into the console, while the physical I/O can be located in a remote rack for optimal signal path management.

Designed for reliability in professional touring and installation environments, the DL444 card leverages the DL431 frame's power and digital connectivity to the main console. Configuration and monitoring are handled entirely through the console's intuitive software interface. By adding premium MIDAS analog I/O with remote-controlled preamps in a modular form factor, the DL444 provides system designers and engineers with a flexible tool to scale their console's local analog connectivity, ensuring that the celebrated MIDAS analog sound quality is maintained when integrating additional outboard gear, playback systems, or stage inputs into a digital workflow.
