Behringer MX400

+ 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".

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.

I just wanted something decent and simple for home playing, for split signal in one amp or similar. And I bought just that - a simple, sturdy little mixer that I can put in my pocket.

output is mono so keep that in mind. Build is good, metal case. Knobs are sturdy. Power supply is included so it's ready to go. Works as it should. Wish it was stereo out (for headphones), but works as a way to combine audio from 4 devices.

I use it for integration in my liveset,. Silent, built like a tank, does exactly what I bought it for,.

I think this mixer is great for it's price. I use it to mix my volca fm with my minilogue. The metal build quality is great, and I love that the power supply is included. My only problem with this mixer, is that I wish the output was stereo, instead of mono. Since the output is mono when I connect my headphones to the mixer, I can only hear sound through one ear. If you want to fix this you'll need a mono to stereo adapter, which are pretty inexpensive.

I use this to combine inputs from different folk instruments into one DI box for when gigging. Some are passive, some are active piezo, one is active humbucker.

Unity volume seems to be at about 1 o'clock, increasing the gain on any input channel beyond this may start to overdrive (though it keeps in clean on passive instruments).

The build quality is solid, and dials move smoothly. Comes with a EU 12v power supply and adapter to the PSU needed for your country.

I use it to connect two guitars (can connect upto 4) to one amp. Works pretty well, and is very simple to use. There is however a little white noise that it adds to the output. Not very loud, but it is audible. Definitely not recommended for recording, but works for me for practicing with a friend.

Very simple 4-channel mixer. It introduces some noise but it is bearable for the money.

I bought this item in order to use it with Korg Volcas and Monontrons. It's great for a minimal (mono) setup, where your sound depends on the instruments you use (although you could use effect pedals between the units and the mixer). I've also used it as a temporary solution to have more channels in my (small) mixer before upgrading.
