If you are looking for an inexpensive console for normal purposes and are not an audio fetishist, I can recommend this console. For all others who expect high-quality and reliable operation from their equipment, I would recommend buying a higher-quality mixing console.
Variant JB Systems Live-6
This rating has been translated automatically. Original language
What doesn't work well is the recording function. It does record, but there is no song that is recorded continuously and completely. With most songs there is a cut, about 1 bar is missing and then the recording continues immediately. I'm still working on this problem. I'm not sure whether this is only the case on this device or on several Live 6 mixers. If the error cannot be rectified (try several different USB sticks, formatted and not formatted) and I am curious to see if anything changes.
My conclusion, for small gigs in any case very well suited, makes on the whole not a bad impression. Definitely worth recommending for the money.
The workmanship and feel are also good.
