The RDL ST-MLX3 Radio Design Labs Mic Line Level Mixer is a versatile and high-performance audio mixing solution designed for use in various radio and broadcast applications. This compact mixer, measuring just 1 RU (rack unit) high, offers exceptional audio quality and an intuitive user interface that makes it an ideal choice for both experienced audio professionals and those just starting out.
At its core, the ST-MLX3 features three line-level mic inputs, each equipped with a 20dB pad and a 48V phantom power switch. These inputs are able to accept a wide range of microphones, from dynamic to condenser, ensuring flexibility for any broadcast scenario. Alongside the mic inputs, the mixer also includes an additional line input for connecting sources such as CD players or turntables, as well as a stereo RCA input for external sources like MP3 players or computers.
Each channel on the ST-MLX3 is outfitted with a 3-band EQ, allowing users to fine-tune the sound of their microphones to perfection. The EQ includes a 10kHz high-frequency boost/cut, a 1kHz mid-frequency boost/cut, and a 100Hz low-frequency boost/cut. This level of control makes it possible to compensate for room acoustics, eliminate unwanted noise, and shape the sound of each microphone to suit the specific needs of the broadcast.
The mixer's user interface is designed with ease-of-use in mind. Featuring large, illuminated VU meters, users can easily monitor the levels of each input, as well as the master output. The mixer also includes a headphone output with its own level control, allowing users to monitor their mix in private or while on the go.
The ST-MLX3 is built to last, with a rugged steel chassis and gold-plated RCA jacks that ensure reliable performance in even the most demanding environments. The mixer also features balanced XLR outputs, making it easy to connect to a power amplifier or other professional audio equipment.
