The Midas DL153-UL is a professional, rack-mountable digital stage box designed as a remote input/output extension for compatible Midas digital mixing consoles, such as those in the M32 and DL Series. Its primary function is to be placed on or near the stage, converting up to 16 analog microphone or line-level signals into a digital audio stream that is transmitted to the main console over a single Cat-5e or Cat-6 Ethernet cable via the proprietary Midas DL protocol. This setup dramatically reduces the amount of analog cabling required between the stage and front-of-house position, improving signal integrity by minimizing noise pickup and simplifying setup. The unit is equipped with 16 of Midas's renowned microphone preamplifiers, known for their musicality, headroom, and low noise, ensuring that the critical first gain stage in the signal chain maintains the console's sonic quality.

In addition to its 16 inputs, the DL153 provides 8 analog outputs, allowing it to also function as a digital-to-analog converter for sending mixes, effects returns, or other console outputs back to the stage for power amplifiers, in-ear systems, or stage monitors. This bi-directional flow of high-channel-count audio over a single network cable is a cornerstone of modern digital live sound systems. The stage box features robust construction with metal chassis and Neutrik connectors, built to withstand the physical demands of touring and frequent setup/teardown. Its UL certification indicates compliance with specific safety standards, which is often a requirement for professional installations in various venues and regions.

Operation is seamless when connected to a compatible console; the preamp gains, phantom power, and other parameters for each channel are controlled directly from the mixer's surface, as if the preamps were internal to the console. The DL153 forms a key component in a scalable system—multiple DL Series stage boxes can be linked together to expand the total channel count available to the mixer. By offering high-quality preamps, reducing cable runs, and providing a reliable digital audio network, the Midas DL153-UL enables live sound engineers to build cleaner, more flexible, and sonically superior systems for a wide range of events, from club gigs to touring productions.
