Sound quality is good, no doubt about that.
I use this box as an interface for FOH connections in an LV-1 Soundgrid network, and surprisingly the preamps are not digitally controlled. Just something to be aware of. You DO have physical knobs for gain control, so that is perhaps to be expected. To me this ought to be the perfect I/O companion at smaller shows, but it is a bit bulky and to be honest quite ugly. It also lacks a proper Ethercon connection, which is a bit of a shame. High impedance inputs are also a bit of an odd feature for my personal purposes.
Build quality is great and it really is as sturdy as it looks.
