Purchased for occasional sound of sporting events. Impressively the equipment given the price. The slider ways are perhaps a bit short, the knob may be slightly fiddly, the MP3 player is capable of improvement, the DA converter certainly not the best of Mikrofonzug certainly not the lowest noise, the whole thing exudes beside functionality quite the impression of cost optimization in design and production .... but: for as little coal is all off, what I need, I got it right away to easily get it running. With amplifier, microphone, CD player, USB stick and headphones. The next mixer has perhaps' ne simple tone control. Otherwise I would not know what I should complain.
