4-Channel Line Mixer

Despite its ultra-compact size, the MICROMIX MX400 4-channel line mixer is really big on features! Providing the highest sonic quality at all output levels vs. the competition, the MX400 features ultra low-noise 4580 operational amplifiers for outstanding audio performance – the same chips as the ones found in its much bigger mixers. Use the MX400 as a sub-mixer for your mixer: If you are running short on available channels on your “big” mixer and need to add 3 more keyboards to your mix, just connect them to the MX400, dial-in the mix – and connect MX400’s output to a single input on your main mixer. This way you have the opportunity to mix your keyboard with the MX400, without immediately occupying several valuable mixer channels.

Cheap and simple mixing desk
Anonymous 04.12.2014
I was needing a mixing apparatus so i could merge various signals from different sources and the Behringer MX400 was the cheapest, simplest and smallest of all.

It does a decent job as its low in noise if you don't turn it up to 11.
The small form was a deciding factor as i can use the mixing desk on top of my synths or on my pedalboard without to much hassle.
It has a great feature that is working as a passive mixing desk if the power is out.

The building is ok with a metal chassis and the knobs feel fine.
I have used it in more applications that I was thinking of when i get it.
Sometimes me and my friends want to jam (2 guitars with pedals, a bass and a synth) and now we can all do it using just one amp.

It would be perfect if it could be battery powered but i guess you can't ask for everything at this price point and probably it would drain the batteries in a few minutes so Behringer's engineers don't give us that option.

If you need a small, well build, simple and cheap mixing desk i would recomend the Behringer MX400

Bang for the buck!
anotheri 23.07.2019
+ it's cheap and works as expected;
+ built like a tank;
+ sounds good unless you max its output (you'll get an overdrive in this case);
+ it's quite useful if you need to connect a few instruments to your main mixer or sound interface and has limited inputs on it;
+ but NOTICE! in case you want to use its output with headphones you will need mono to stereo adapter, e.g. "the sssnake 1936 Adapter".

Increases your flexibility in home studio or live situations.
Joe911 20.11.2025
I used this item busking on a 1 channel amp, a guitar and backing track, taking 2 channels. Then at a party an acoustic guitar, bass guitar, and an SM58 into one channel of the PA. I used the small mixer to control sound levels, adjacent to me for local control. The sound is clear, with no artifacts, and a little BluTack affixed to the underside stabilised the unit considering it's lightness and occasional pull from cables. It would be really useful with a 2 channel audio interface to get a total of 5 inputs, or with 2 units, 8 tracks of input 'bounced' realtime into the 2 inputs on the audio interface. That would give your home studio 8 channels of live input for only a cost of €31.40 while you save for an 8 track audio interface. It would be feasible to track a whole drum kit live this way, with only the 2 channel audio interface.

Neat piece of equipment
DimitriosB 17.03.2017
I bought this to combine two guitar channels into one (one with effects and one clean). I wanted something that lets me adjust their corresponding volumes. So Behringer MX400 is definitely doing the trick. I would have loved if the output was stereo and panning options were available, but nevertheless this is a great product. It's actually quite solid, sturdy-made which was impressive for Behringer.
