RDL RU-MX4L overview

  • 1Description

The RDL RU-MX4L is a four-channel audio mixer with XLR and RCA line inputs. Outputs include a switchable balanced XLR mic/line output, as well as an additional unbalanced RCA jack that may be used to link another RU-MX4L or RU-MX4LT. This mixer is useful for combining balanced line and unbalanced line inputs into a single output. The RU-MX4L is suitable for small sound reinforcement, public address systems, or mixer expansion applications.

You'll note that for outputs, you have the options of an RCA out or a balanced XLR out. The XLR output is switchable between mic or line level. While you can only use one input configuration at a time (either XLR or RCA), you can use both outputs simultaneously.

Levels can be adjusted on the front panel, which leaves you enough space to label each input. Each input sports a dual-LED VU meter following standard VU ballistics with a green indicator for signal and a red LED when you go over the correct operating level. The output is displayed on an LED string VU meter. Please note, you must purchase the corresponding PS-24AS power supply separately.

Four Line Input Channels
Each channel features a balanced XLR line input and an unbalanced RCA line input.
Flexible Output Section
The outputs consist of a mic/line selectable XLR channel, and an unbalanced RCA output that may be used for linking multiple mixers.
