Product Description
RDL RU-MX4LT Professional 4 Channel Line Level Mixer with Transformer - Microphone and Line Output
Overview
The RU-MX4L is the ideal choice in many applications where a combination of balanced and/or unbalanced line-level signals needs to be mixed. Balanced connections use XLR connectors. Unbalanced signals are coupled through phono jacks. Each of the four RU-MX4L inputs can accept either a balanced XLR line-level input or an unbalanced line-level phono jack input. The unbalanced phono jack LINE OUTPUT from one RU-MX4L may connect to the unbalanced input of other equipment, or may be connected to the DIRECT input of another RU-MX4L or an RU-MX4 to expand mixing capabilities. The RU-MX4L provides one balanced output, switchable for mic or line level. Audio levels are adjustable on the front panel. Each input channel is equipped with a front-panel dual-LED VU meter that follows standard VU ballistics. The final mix is displayed on an LED string VU meter featuring a visually comfortable arc motion. A factory installed output isolation transformer is available by ordering the RU-MX4LT.
