Xenyx Q502USB : Sub-entry level device

I bought this device to use it in online lessons and to record some basslines for learning purposes. It is barely usable.

The power supply connector has a very weak grip and disconnects frequently as you try to move the xenyx. This is annoying. The digital sound going through the USB port is strongly affected by noise in my configuration, i had to fix it by myself. When i bought the device i was convinced 16 bits were enough for learning purposes: they're not, the sound quality is poor, is different from the analog outputs. The analog sound in the earphones and mixer outputs is good, no noise or distortion.

So the conclusion is, xenyx is a small analog mixer, a little unconfortable, that allows you to send digital sound to your PC with poor quality. Not more and not less than this
