The RDL RU-MX4LT 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-MX4LT 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. Additionally, the RU-MX4LT utilizes a factory-installed output isolation transformer to ensure a low-noise, pristine signal path.
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.
