RDL RU-MX4LT - Professional 4-Channel Line-Level Mixer with Transformer and Mic Output

The RDL RU-MX4LT is a professional 4-channel audio mixer designed for combining balanced and unbalanced line-level signals. Each of the four inputs accepts either a balanced XLR connection or an unbalanced phono (RCA) jack. The mixer provides both an unbalanced line output and a balanced XLR output, which can be switched between mic and line level.

Designed for installation and studio environments, the RU-MX4LT delivers low-noise, studio-grade performance. This version includes a factory-installed output isolation transformer, ensuring galvanic isolation and minimizing interference in AV systems.

Each input channel features independent level adjustment and a dual-LED VU meter. The final mix is displayed on an arc-style LED VU meter for clear visual monitoring. The mixer also supports expansion via the DIRECT input and LINE OUT, allowing it to be linked with other RU-MX4 or RU-MX4L units.
