The RTS MDA-100 is a professional mixing distribution amplifier designed for critical audio signal management in broadcast, production, and installed sound environments. Its primary function is to accept multiple audio inputs, combine (mix) them into a single output, and then distribute that mixed signal to multiple destinations with clean, isolated amplification. This makes it an indispensable tool for creating program feeds, submixes, or routing combined audio sources to various recorders, monitors, or transmission lines without signal degradation or ground loop issues.

The unit typically features several balanced microphone/line-level inputs, each with individual level control, allowing for precise balancing of sources before they are summed. The mixed signal is then fed to multiple independent, transformer-isolated outputs, each capable of driving long cables without noise or level loss. This combination of mixing and distribution in one rack-mountable unit saves space and simplifies signal flow in complex audio systems, such as those found in television studios, radio stations, and live broadcast trucks.

Built to RTS's high standards for reliability and audio quality, the MDA-100 is engineered for continuous operation in demanding professional settings. Its robust construction and transparent sound ensure that audio integrity is maintained from source to destination. By consolidating mixing and distribution tasks into a single, reliable device, the MDA-100 provides audio engineers with a versatile and efficient solution for managing multiple audio feeds and creating clean, distributed program audio.
