This yamaha mixer, is a nice small mixer with decent features and audio quality.
There are however some small issues with it.
If you use the USB audio interface, for both input and output, there is some crossover effect, and this make the USB interface not usable as both recording and monitor return, so if you plan to use this feature combo, then you will be disappointed.
But as long as you only use the USB interface one-way it works fine.
Also the power supply is an old school AC supply, that is quite large and unhandy, compared to the mixers size.
