          I used this device when we ran out of inputs to our rack mounted mixer. We needed line level feeds from video players and computers. It was quiet as long as you use quality input cabling that is well shielded. If you use crummy cables, you will pick up hum. The small size made it so we could set the controls and mount it out of sight inside the rack.

            I ordered this product to replace a Presonus version of something similar, because the software with Presonus does not work under the latest Mac OS X operating system.I use it to mix two to three microphone inputs. It works very well. Plugging into the Mac and making it work was a breeze.Since I'm exploring this area this inexpensive way of combining signals works very well.

                  I use it to add multiple mics to the mix without having to break out the full mixer. It will produce white noise at more than 12 o'clock setting, but you cannot hear that when the music is playing. So overall, I give it a 4.5

                    Comments about Behringer MX-400 MicroMix - Four-Channel Line Mixer:

                    I can see this product having so many different purposes but I use it mainly for connecting various instruments with 1/4" lines. I've connected acoustic guitars, electric guitars, electric bass guitars, electric drum set, keyboards, microphones, and computers (with adapter).
                    I use this little box for practicing. Kind of like a make shift JamHub. I also use it to add more 1/4" inputs to my mixer.
                    The first one I purchased about 4 years ago had a cable that disconnect from the unit very easily. I recently ordered a new one and the cable is much better. These new ones stay in the unit.
                    It has basic volume functions. I wouldn't say this thing has limited functions because if you are looking for something with more functions, then obviously, you need to look somewhere else. This is a very simple unit that gets the job done.
                    It seems that people like to know where the review is coming from so...I have been recording and mixing music for many years and have a bachelor's degree in Recording Technology. This is a great product. You don't need to get a more expensive one just because of the brand. If this is all you need, why pay more?

                          Micromix is used with my effect rig to allow three stereo pedals run into a dual amplifier rig. I keep all levels between 12:00 and 1:00. If i need more volume i turn the second amp up.

                            I use the micromix to play music from a computer or I-pod and a CD player through the house pa. This is particularly helpful in rehearsals to review arrangements of songs the band is playing. The best thing about the MicrMix is that it mixes down to a mono output so it only takes one channel from the house mixer. That leaves another channel for instruments. I don't need stereo anyway because the monitors are mixed in mono. The MicroMix is also simple to setup and operate. Just plug in the inputs and single output and turn up the volume levels.

                                    This unit includes a power supply which is not included with some similar battery operated models from other manufactures. So, unless you enjoy replacing batteries on a regular basis I would recommend this unit.

                                    I used this to mix my ipod and guitar into the amplifier and it doesn't sound half bad. It works exactly how I thought it would work. I turned the IPod channel down and the guitar channel up and it doesn't sound too bad for a single speaker mono setup. Of course I had to by the 1/8th inch stereo to 1/4 inch mono adapter from[...]

                                      It does what it was designed to do, and it's quiet. I power it with the Voodoo Lab Pedal Power II Plus, and it works like a charm.

                                      I use it to mix the outputs of my Boss AC-3 Acoustic Simulator and my T.C. Electronics Nova System into one send which goes into my Boss RC-20XL Loop Station. It makes it nice and simple to seamlessly switch back and forth between guitar sounds, and still have the ability to layer everything into the Loop Station.

                                        Great small mixer for those who need to sum up to 4 inputs to a single output. We use it to join two stereo headphone outputs from two Yamaha consumer keyboards into one output going to a single powered speaker for dual keyboard stage performances. Dislikes: The one I received still uses the old transformer type power supply instead of the newer cool running switching (and multi-voltage) supply. Mfr web page appeared to show mult-voltage capability, so I was expecting the switching supply.

                                          I use this product for drum click track mixing. A click track is fed into channel-one while a track with all backing audio is fed into channel-two. I then feed the output to a headphone amp which drives in-ear monitors that the drummer wears. Once again keep in mind this is strictly a mono mixer.

                                          Overall does exactly what I hoped it would do and I would most likely purchase this or another Behringer product again.
