Short and sweet. A solid, well made bracket that you screw to the bottom of the P16 mixer to attache to a mic stand with the supplied adaptor, or direct to a mic stand. The only annoying feature is that it's too easy to lose the special adaptor, and it's not a thing you can source locally, or bodge up - so hang onto it. It would be nice to have a quick release from the P16M, but the angle plate is not a quick attachment to do at a gig. Screw it on, and leave it alone. It makes the mixer heavier, and a bit chunkier, but not causing us any real issues. Quite expensive, when Behringer could simply have put a stand mount hole in the bottom of the mixers, but there you go!
