RDL RU-MLD4T - 1x4 Microphone/Line Distribution Amplifier with Transformer

The RDL RU-MLD4T is a professional 1x4 audio distribution amplifier designed to split a microphone or line-level signal into four independent outputs. Each output is equipped with a studio-grade isolation transformer, ensuring galvanic isolation and minimizing interference.

Both the input and all outputs are available on front-panel XLR connectors and rear-panel detachable terminal blocks – all active simultaneously. The input can be configured for mic or line level via a rear-panel switch. Additional switches allow selection of LO or HI mic gain and activation of 24 V phantom power.

Each output can be independently set to mic or line level. Input gain is adjustable via a front-panel trimmer, and signal level is monitored using a dual-LED VU meter calibrated to +4 dBu for line-level outputs. Outputs are isolated and may be wired balanced or unbalanced.
