I bought this mixer for our project studio as the main interface for anything computer based. Having loads of experience from the top end of live audio I never really favored Yamaha in any way but I have to say I am pleasantly surprised about what this little thing can do. It's well built, with proper pre-amps on four of the 10 channels, nice gain structure but most importantly, it sounds very good for such a cheap mixer.
It ended up doubling as the ASIO interface for the main work station and it's doing just fine although we had to download the latest drivers from Yamaha before we got it working. If you experience intermittent noise on the outputs, it's a driver problem on Win 10. Under Ubuntu on the Linux side it works flawlessly out of the box though.
If any critique what so ever, I would say I miss a mix bus. A single mono bus would even blow the competition out. Other than that, the controls are small and can be a tiny bit fiddly but that's the logical price for such a compact unit. The built in FX bus based on the SPX engine is just that. If you are ok with any Yamaha SPX series, you will be ok with this. But it's not a Lexicon for sure! Finally the compressor just about ok for say streamers, but honestly, it's nothing I would ever use.
All in all, fantastic mixer that within the price range, beats an competition provided you ignore the compressor and lack of mixing busses.
