The RDL RU-MX4L is a professional four-channel line-level audio mixer designed for installations requiring flexible mixing of both balanced XLR and unbalanced phono jack inputs. Each channel accepts either a balanced or unbalanced line-level source, making the RU-MX4L ideal for commercial AV, broadcast, conferencing, production facilities, and system integration environments.
The RU-MX4L provides a balanced XLR output, switchable for mic or line level, plus an unbalanced line output for connection to additional mixers or equipment. A DIRECT input allows seamless expansion by linking to additional RU-MX4L or RU-MX4 mixers.
Every input channel includes a front-panel dual-LED VU meter, and the final mix is displayed on a smooth, arc-style LED VU meter for accurate visual monitoring. Built with studio-quality, low-noise circuitry, the RU-MX4L ensures clean, reliable performance in demanding audio systems. For installations requiring transformer-isolated output, the RU-MX4LT version is available.
