RDL ST-MX2 2-Channel Audio Mixer, Microphone or Line Input and Output

The Radio Design Labs ST-MX2 2-channel audio mixer delivers reliable, professional mixing where clarity and simplicity matter most. Built for AV integrators and security professionals, the ST-MX2 lets you combine a microphone with a line-level source (or two mics) and feed balanced or unbalanced outputs into amplifiers, recorders, or monitoring systems. With selectable mic or +4 dBu line inputs, low-noise circuitry and dual-LED VU metering, it preserves speech intelligibility for surveillance, paging, and monitoring applications. Its balanced outputs and 24V DC power option reduce interference on long runs common in security installations, while the compact footprint makes it easy to add two channels to existing racks or field panels. Use the ST-MX2 as a dedicated mic preamp, a mono-sum line adapter, or a simple mixer for control rooms, access control sites, and broadcast monitoring. Enhance your security or AV system with the dependable performance of the ST-MX2—order now to streamline audio integration and improve on-site intelligibility.
