Behringer MX400 MicroMIX 4-Channel Mono Line Mixer for Guitar, Synth, Podcast & Studio, Ultra Low-Noise Audio Blender with Level Controls, 12V Adapter Included

Great value for money! Works very well!

There not a lot to it and the knobs are pretty cheap feeling, but the unit itself is metal in construction and (most importantly) I haven't noticed any noise from the unit or crosstalk from the inputs. It's pretty silent in operation. (I've had a couple of Behringer's Xenyx mixers in the past and they have been far from silent, but no complaints here.) I was concerned there were no mute buttons, but when a knob is on zero it does seem to completely cut all signal, so less of an issue than anticipated. I'm using this as sub-mixer for a rack of 3 desktop synths before feeding to a Zoom MS70CDR effects pedal and on to inputs on my Scarlett 18i20 and in this configuration I haven't heard any extra noise, whine or hum added to the signal, so for the money, a perfect solution for a simple submix if you just want to sum or mix between a few bits of external gear and don't need the EQ, sends etc you might find on an 'actual' mixer.

This 4 channel Mixer is an essential part of my pedal board and does the job well but unfortunately doesn't use the standard power connections that all other guitar pedals use, so needed a special cable rigging to hook it up to the pedal board power supply unit, as it is a different plug size and uses +ve centre rather than the standard -ve centre pin. It is spec'd at 12V but works OK with 9V with the specially made power cable converter. It does come with an appropriate 12V power supply if you want to use a separate mains plug to power it.

A minimal powered four-channel mono mixer, including power supply, for under £20 - what's there not to like? Obviously such a stripped-down piece of hardware is going have its limitations but if you can work within those constraints it will serve you well. The main creature comforts it's missing are a master output level, pan controls and a stereo output. The fixed master output level isn't a deal-breaker at the price and simply requires a little more care when balancing the input levels. If stereo output is a requirement then this isn't for you unless you're willing to adopt a hardcore dual-mono approach and buy two of them. It's also not quite as portable as it could be given its dependence on the supplied PSU so you're unlikely to be jamming off-grid, but for something you can throw in a bag, set up anywhere where there's mains power available and not worry if it doesn't make it back alive, you'll struggle to find anything better for the money. Mono output isn't that much of an issue for live use as many PA systems will mix down to a mono output anyway, and while home users may miss having a stereo signal path for recording purposes a mono signal path is perfectly fine for performance purposes. I bought one as a semi-disposabe and extremely portable mixer to go with my Korg Volca modules for casual jamming with friends and its minimalist limitations haven't got in the way of creativity at all. The one thing that's not been mentioned so far is sound quality. "Good enough" is the bottom line. I found no obvious issues with noise and interference and the output sound lacked any obvious colouration. We're not looking at audiophile/reference grade at this price point but regardless I found nothing to complain about. Things have come a long way for budget equipment. A long time ago I bought a Technics SL-1200 bundle which came with a Soundlab DSM-15 mixer, an equally budget-conscious design like the Behringer but with truly dreadful sound quality and essentially unusable for performance work. Behringer have proven time after time that it's possible to have decent quality audio at a modest price tag, and the MX400 doesn't disappoint.

Ordered this twice now after returning the original for not having a UK spec plug. Was promised by amazon customer service that if I re ordered it would be fine. Parcel turned up today with yet again a non uk plug on it.. the product its self is great and I have a couple of others it's just a certain seller selling what I guess is European stock not uk. Amazon really need to control this better. If it had had the correct plug it would have Been 5*

Needed this because my guitar amp only had one input. Ended up plugging in a few guitars a mic and my looper. Easy to set up and balance, do get a very slight hum but not so you would notice and no impact on the sound. I think it is more the fault of my aging amplifier than this mixer. Overall, small, neat and very capable for people like me that don’t have too much to spend. A great asset to my setup that has given me good flexibility with both guitars and mic for a low price.

Had to order a shaver adapter before I could use this in the UK as it doesn't come with three pins which is annoying. I connected my mic, guitar and connected in the unit to my Bluetooth modelling amp. You have to work the volume controls to stop feedback and there is a slight hum although this is drowned out when playing music. It gave me a solution to connect multiple items to play my music at home so it's ok. I'll have to try and find a solution, rather than bluetack to hold it in place from moving around though

This is very impressive indeed, especially at the price, but quite a few people seem to be having problems simply because they don't know quite what they're buying, so here's a quick introduction to mixer technology...... Firstly of course, it's clearly sold as a "4 Channel Mono Line Mixer", so I really don't understand why so many are complaining that it isn't stereo :~) A line mixer is a specific thing, it's function is to provide a sub-mix of line level signals, in this case mono signals, and to output a single line level signal. The output has to go to a device that will take a line level signal (amplifier, main mixer, some effects pedals, etc....) It won't directly drive a speaker. You might get a quiet or distorted sound out of a pair of headphones, but extended use will probably damage the unit as, because of the impedance mismatch, the circuitry will be drawing far too much current All audio equipment, no matter how good or expensive, generates some background noise, this is known as the noise floor. Although they don't give any figures, I've measured it and the noise floor is ridiculously low, and running at the levels it's designed for any noise is, for practical purposes, non-existent. Although not designed for it, the unit is versatile enough to work with much lower level signals from guitars and even some microphones, but in that case you have to be careful with levels otherwise some background noise can become audible. Any background noises you get other than a hiss are down to dodgy output stages on whatever you've got plugged in (Phones, tablets and cheap laptops are notoriously bad!). At the other end, if the signals going in are too high it will eventually distort. If so , you just have to turn everything down! I originally got mine for general studio duties - temporary hook-ups of odd bits of equipment, but within an hour it found a permanent home attached to a Behringer RD-8 which has separate outputs for each drum sound. I can now route some of them out for effects processing, recombine them, and either back into the return socket on the RD-8 or to a second main mixer channel. Looks like I'll have to buy another one...... ;~)

Der kleine Mono Mixer macht was er soll. Die Qualität ist Hardwareseitig sehr stabil und haptisch gut. Die Regler gehen mit angenehmen Widerstand und sind stabil montiert, sie wackeln nicht. Die Ein- und Ausgänge sind für MONO-Klinkenstecker mit 6,3mm. Ein passendes Netzgerät liegt bei. Die Audiosignale werden unverfälscht und nahezu rauschfrei übertragen. Er ab ca. 3/4 offener Reglerstellung beginnt man sehr leises Rauschen wahrzunehmen. Das ist ein MONO Mixer, der LINE Signale mischt und MONO ausgibt! Wer Stereo braucht kann 2 davon verwenden (Für Links und Rechts jeweils einen MX-400). Das funktioniert gut und zuverlässig. Der MX-400 ist extrem klein und leicht. Fixierung funktioniert mit „Uhu Patafix“ (dann bleibt er wo er ist, lässt sich aber leicht wieder entfernen) oder mit selbstklebenden Gummi/Silikonpads. Diese lagen zumindest meinem bisherigen zwei Exemplaren nicht bei. Fazit: Kaufempfehlung wenn man weiß wofür. Tipp: Unterschiede der Signal-Pegel von LINE, Instrument und Balanced bzw. Mikrofon googeln.

He comprado varios y los usamos entre varias personas de forma intensiva a menudo y han dado cero problema. Es muy práctico y sencillo de usar. No hemos tenido ningún problema con ninguna de las fuentes de sonido que hemos conectado (móviles, micros, etc...), ni con los dispositivos de salida. Muy buen dispositivo a precio ajustado. ¡Recomendado!

Great for adding more inputs to your mixer.

Amazing what a small, inexpensive micro mixer can do. It solved my problem of connecting four instruments to a single output, and now I can control the volume of each one individually. As a bonus, it also eliminated the static noise I’d been trying to fix for months. Sometimes the simplest solutions work best.

I needed something that would allow me to connect multiple instruments to my Boss RC-1 looper pedal so I could layer them all on the same pedal through the same amp. I've bought a few Behringer guitar pedals before, and I've had mixed feelings about them. They were really cheep and sounded good enough, but were made of flimsy plastic. This mixer is a different story. The housing is metal and everything feels sturdy, very impressive. Basically, the mixer has 4 mono 1/4 size input jacks and 1 mono 1/4 size output jack. It requires a 12v power adaptor, but it comes with one, which is really nice. The included power adapter did feel a little flimsy, but it works fine and only takes up one outlet space. Setup was easy, I was able to connect my drum machine, synthesizer, guitar, and bass, to the mixer. I do wish that the input jacks were more spaced out though. Really, the only cables that are going to fit are ones with straight connectors. I had a lot of trouble with my right angle patch cables, they didn't fit. I made it work, luckily I had some straight cables. The mixer works really well, sounds good, etc. I do wish it had a power switch, it's a little annoying having to unplug it every time I want to turn it off, but I can't argue with the price and build quality. I did notice that my guitar and bass sounded really nasty when I turned the volume knobs on the mixer up past 50%, but that may have just been the nature of the instruments and the presets on other gear in my setup. Those instruments sounded fine when the mixer knobs were kept low and other volume knobs elsewhere were turned up. Overall, Behringer really outdid themselves with this little mixer. The price is unbeatable and it works just as expected. It's really great to have this tiny thing I can stick onto the side of my pedal board instead of having to use a huge mixer board. Definitely would recommend.
