About the Midas DL151 24 Input Stage Box w/ 24 Midas Microphone Preamplifiers
The Midas DL151 is a high-channel-count digital stage box dedicated to providing pristine audio capture at the source, equipped with 24 discrete Midas-designed microphone preamplifiers. It functions as the primary remote input hub for compatible digital mixing consoles, transmitting high-fidelity digital audio over a robust AES50 network connection to replace lengthy and noise-prone analog multicore cable runs. This unit is engineered for applications demanding a large number of simultaneous, high-quality microphone inputs, such as major live sound events, broadcast productions, large houses of worship, and theatrical performances, where maintaining sonic integrity from the stage to the mixer is critical.
Each of the 24 input channels features the transparent and musical gain structure characteristic of Midas preamps, accessible via combo XLR/TRS jacks that accept both microphone and line-level signals. All parameters—including gain, phantom power (+48V per channel), a 75Hz high-pass filter, and polarity reverse—are fully remote-controllable from the connected console's surface or software, giving the front-of-house or monitor engineer complete command over the input stage from a distance. The stage box digitizes all 24 channels at sample rates up to 96 kHz and transmits them, along with digital returns from the console, via its dual AES50 ports using standard shielded Cat-5e cable, ensuring a clean, low-latency signal path over distances up to 100 meters.
Housed in a durable 2U rack-mount steel chassis built for touring, the DL151 emphasizes reliability and seamless integration. Its dual AES50 network ports support daisy-chaining multiple stage boxes or configuring redundant network loops for enhanced system stability in mission-critical applications. The unit can be powered directly through the AES50 link from a console equipped with a dedicated power supply or locally with an external adapter. By concentrating a significant number of premium preamps into a single, network-efficient device, the Midas DL151 offers system designers a scalable and sonically superior solution for expanding a digital mixer's input capacity, ensuring that every source is captured with the clarity and depth expected from the Midas legacy.
