Very decent sound quality in both live and recording applications. Very versatile of having XLR, 1/8, 1/4 Jack mono and stereo input. This plus version with Bluetooth input is definitely my favourite features. FX is good to have and I don't use it. The only negative comment for me is the design of the firmware. As an audio interface, I prefer its default computer output map to channel 1/2 instead of 3/4. It causes me sometime to configure various software for playback audio.
