I’m having different audio sources that I want all to be played by the same boxes. I don’t expect anything fancy, only bringing the signals together (hence I hope to get it cheap) while maintaining the quality.

As I read through the internet, when it comes to quality it’s where all the affordable ones seem to stay behind. And I’m afraid of tuning the sound to an ill manipulated signal that is added by the mixer and not the track itself.

I first thought about Behringer MX400.

Any experiences on that field? Am I over-engineer it or is this a valid error source that I would introduce, which wasn’t there before?

Thanks ahead!
