The MIDAS DL431-UL is a professional active microphone splitter system designed to provide multiple, isolated outputs from a single set of microphone inputs, a critical tool for large-scale live events where one stage setup must feed separate mixing consoles. It features 24 high-quality MIDAS Pro Series microphone preamplifiers that accept the original microphone signals from the stage. Each preamp output is then actively split to provide three completely isolated and buffered outputs: one direct output and two transformer-isolated outputs. This configuration allows the signals to be sent to three separate destinations—such as a front-of-house console, a monitor console, and a broadcast or recording truck—without ground loops, signal degradation, or any interaction between the consoles.

Engineered for reliability in demanding touring environments, the DL431-UL is housed in a robust 3U rack-mountable chassis. Its independent preamplifiers offer individual gain control, phantom power (+48V), and polarity reverse for each of the 24 channels. The transformer-isolated outputs provide complete galvanic separation, eliminating hum and buzz caused by ground potential differences between the various systems. The unit is powered by an internal power supply and includes comprehensive status indicators. By centralizing the gain staging at the splitter, it ensures that all engineers receive an optimal signal level, and the FOH engineer typically controls the master phantom power for the entire stage.

As a cornerstone of professional live sound for major tours and festivals, the MIDAS DL431-UL combines pristine audio quality with practical problem-solving. It eliminates the technical compromises and potential noise issues associated with passive Y-cable splits. By providing three clean, independent feeds from one set of microphones, it enables seamless collaboration between separate audio crews, ensuring that front-of-house, monitors, and broadcast each receive the highest quality signal without interfering with one another's work.
