Product description The RDL RU-MX4T is a four-channel audio mixer with XLR mic inputs and RCA line inputs. It provides 24V phantom power on a per-channel basis for microphones that require it. Also on hand is a switchable compressor/limiter to keep levels from peaking, if need be. This mixer is useful for combining balanced mic and/or unbalanced line inputs into a single output. The RU-MX4T 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 unbalanced RCA and a balanced XLR out. The XLR output itself 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-MX4T 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 green indicating signal and red to indicate 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 Mic/Line Input Channels
- Each channel features a balanced XLR mic input and an unbalanced RCA line input. An additional RCA direct input accepts input from another RU-MX4.
- Flexible Output Section
- The outputs consist of a mic/line selectable XLR channel along with an unbalanced RCA output that may be used for linking multiple mixers.
- Phantom Power
- A 24V phantom power switch is located below each microphone input. These switches activate the phantom voltage and set the input preamp for the optimum gain range for the type of microphone. An integral high-pass filter rolls off frequencies below 80 Hz.

| Subject: RU-MXT Professional 4 channel sound mixer | | Date: 11.10.2022 03:12:15 | Name: jerry Oliver | While inventorying my group storage cabinet I came across this sound mixer. I could not locate a power supply. The nomenclature refers to 24VDC with no specifics. I can not find a description that indicates the current plug to match the 24VDC receptive.
I would like to purchase A P.S. that I can adapt to the mixer but I don't have enough info about power requirements. The unit doesn't have an external data plate.
I appreciate any info you can supply. | | Post reply |
