Product Highlights
  • 4-Channel Microphone SubMixer
  • XLR I/O Connectors
  • Individual Level Control
  • Portable Battery Powered

The Rolls MX124 ProMix IV is a lightweight, compact, four-channel microphone mixer featuring 3-pin XLR inputs and transformer-balanced XLR stereo (L/R) outputs. Located on the side of the unit are four 18V DC phantom power switches and four low-cut filter switches.

Individually switchable phantom power supplies allows the flexibility to use dynamic and condenser microphone simultaneously and low-cut filter switches eliminate hum, rumble and noise associated with wind and proximity effect. The front panel reveals level and pan controls for each channel. The 1/4" TRS phone and 1/8" (3.5mm) mini outputs can be used to feed headphones or as alternative stereo outputs. The mixer is completely portable, operating on two 9V alkaline batteries, making it a convenient utility in ENG/EFP, video, sound reinforcement and public address applications.

    I use this on every wedding with 3 wireless mics and one shotgun. XLR in and out makes for very clean sound! Nice to be able to pan mics left or right to get stereo effects. Runs all day on two 9 volt batteries. I use rechargeable lithium batteries. I mount in in an aluminum box that fits between my tripod legs and head (which I sell). You can spend hundreds more and not get better sound!

    This is not a professional product but can be useful for some professional cameraman if you don't have a budget for a sound person and mixer. First, it is a 4 channel XLR input and 2 channel mic. level output, it is useful for a 2 camera interview setup and also shooting a forum with 4 mic., sound can be group and feed to both camera....

    Be reminded, there a output level switch close to the output jack and you have to adjust to a lower level to avoid peaking before first use.

    I have a zoom handle recorder and can be used as sound level monitor/recorder and this device has no meter for sound level. It is better if your camera can generate a 1KHz tone for sound level line up before every use.

      Bought because it was an affordable battery opperated mixer. Went to South Sudan, with very limited local electricity and baggage weight in getting there. Fit nicely in my camera bag (hand luggage) and worked perfectly. Audio sounds greats in the videos. Definitely glad we purchased this and hope to use it for all video shoots from here on out!

          This is mostly for producing wedding videos.
          It's perfect for the price.
          The ability to mix up to 4 mics is crucial.
          Works great for what we need!

                    I purchased this mixer from B&H about 3 years ago and wanted to update my review. I film 60 to 65 weddings a year and needed a good 4 channel field mixer that was small, ran on batteries and had good quality sound. I use 4 mics at almost every wedding and wanted to mix the 4 on the fly to save editing time. I am extreamly happy with this product. The only thing I needed was a place to mount it, so I designed an aluminum box that fits between the tripod head and legs. Many other videographers wanted the same set up so I added the TriPodBox to my website. You can get more info at my kamslider website.

                    Comments about Rolls MX124 Portable 4-Channel Stereo Mixer:

                    Without meters to clearly define if you're peaking or not, you should be very careful to listen intently with a pair of very flat headphones (do not use earbuds).

                    The workflow that we use is:

                    Microphone to Mixer
                    Mixer to Foxtex audio Recorder

                    We decided to adopt this workflow instead of a portable audio recorder because that was not optimal in most of our situations. The Rolls mixer allows for four channels in and outputs them to L/R.

                    It can be used to monitor and maintain wireless microphones which is very nice, and it also has a built in phantom power supply.

                    It mixes four channels down to a 2 channel L/R output, and sounds very clear before getting to the recorder itself, better mic's = better sound.

                    It is a solid device without any issues, and I will be using this on 90% of my film projects, bit or small.

                      I am running 3 H4n zooms on my current show. I have the 3 output/headphone jack from the different zoom running into the inputs, giving us the ability monitor all 3 audio devices without having to constantly unplugging and swapping the devices.

                      Comments about Rolls MX124 Portable 4-Channel Stereo Mixer:

                      The casing of the mixer look very solid the only think that worry me for durability is the plastic female input my connection are tight enough but I am not sure how long it will last. However there a screw beside every connection that make me believe it would be easy to replace the connection if it broke off.

                      The knobs for the levels fell smooth and accurate but I have not fully tested yet. There is four input for two outputs (channels) its very easy to pan your input to the channel that you want. For an example in a concert you could put three instruments in one channel and the vocal in the other one. The battery life is pretty good, I have use the mixer for more then 5 hours in a row and the batteries were still good.

                      I bought this mixer to plug into my Zoom H4N (sound recorder). The H4N as weak preamp, with this mixer I can set the gain very low on the H4N and still get strong levels with almost any noise (a lot better then if you set the gain to the max on the zoom). The smooth and accurate knobs make things a lot easier to mix the levels instead of pressing on a clunky and noisy button.

                      The biggest flaw on the mixer is there is no 48v phantom power. My mic as battery inside for phantom power so I don't really need that but sometime I have to rent out an extra mic, because of that I can't always rent the microphone that I really wanted.

                      The mixer is a little bit bulky (16cm, 11cm, 6cm) I been using it as field mixer. I have not find a way to mount my recorder or found a bag that let me mix on the mixer and have a clear view of my levels on the Zoom H4N.

                      For the price and sound quality, I think the mixer is pretty good buy.

                      English is not my first language so I apologize in advance for all the grammatical errors.

                      I was introduced to this little MX124 mixer. WOW! Love at first sight.4 channels of balanced input, 2 channels out, every feature you'd expect of a Shure FP-32 (like I am replacing) or FP-33, except - I'll admit, no tone generator or useless built in VU meter. Big deal. I set up this little guy, tested it out and was really pleased with the ease of use, sound quality and convenience! Look, for less than [$], you can have a really useful, professional level mixer that works for tons of applications. Sure, you can spend a lot more and get a superior product, but face it? Who needs a Rolls Royce when a Zip car will do?!

                        This is an inexpensive field mixer which has some limitations. The lack of VU meters or more than a single clipping diode limits its usefulness in setting levels. The switches require the use of a pocket knife or small flathead screwdriver to set.

                        However, it fills a need that I have for a battery powered mixer that I can carry in my sound bag to be used in video recording. Left to right pan centering which outputs to XLR plugs. Controls are more ballpark than accurate. Sound quality is OK for field video forget it for studio work.

                        It needs to come with a strap to hang it on the camcorder tripod.

                            Use this for small radio remotes where I need to just mix two or three headset levels before hitting the codec. Dead useful, battery life is pretty good too.

                              Hi, I do a lot of ENG field work and to be able to use a mixer of 4 mikes all needing different requirements this MX124 saves my work most days several times over. I recently gluded it to a heavy bracket so I can load it directly on to a tripod with a recording deck.... and 2 wireless recivers..Brilliant

                                  What can I say. It does everything I need. The price is right and although it cannot be hooked up to a tripod, you can buy a strap for it or put it in a carrying bag with your other sound equipment (like receivers and extra connectors etc.).

                                  Overall a great little unit.
