RDL RU-MLD4 - 4-Channel Microphone/Line Distribution Amplifier

The RDL RU-MLD4 is a professional 1x4 audio distribution amplifier designed to split a microphone or line-level signal into four independent outputs. 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, providing full flexibility for integration with various AV systems.

Input gain is adjustable via a front-panel trimmer, and output level is monitored using a dual-LED VU meter calibrated to +4 dBu for line-level outputs. Outputs are isolated from each other and may be wired balanced or unbalanced. The RU-MLD4T version includes studio-grade output transformers for galvanic isolation.
