The RDL RU-MLA2 is a dual-channel, transformer-isolated microphone and line preamplifier module designed for installation in professional audio systems. It provides clean, low-noise gain for microphones or line-level sources, making it ideal for integrating into mixing consoles, DSP racks, or custom audio panels in fixed installation environments such as broadcast studios, houses of worship, conference centers, and performance venues. Each of the two independent channels features a combination XLR/TRS input jack, allowing connection to both balanced microphones (with switchable +48V phantom power) and balanced or unbalanced line-level sources.

A key feature of the RU-MLA2 is its high-quality transformer isolation on both inputs and outputs. This isolation effectively eliminates ground loop hum and protects sensitive downstream equipment from voltage spikes and RF interference, which is critical in complex installed systems. Each channel includes a precise gain control, a peak LED indicator to prevent clipping, and a balanced XLR output. The module is designed for easy integration into RDL's FP-SERIES or other compatible chassis that provide DC power, simplifying installation and reducing wiring complexity compared to standalone preamps.

Constructed on a durable printed circuit board with professional connectors, the RU-MLA2 is built for reliability in 24/7 operation. Its compact, modular form factor allows system designers to incorporate high-quality preamplification exactly where it's needed within a rack. By offering transformer isolation, flexible input options, and clean gain in a dual-channel module, the RDL RU-MLA2 is a fundamental building block for ensuring optimal signal integrity in professional installed audio systems.
