Lead maybe you can elaborate on where the line between consumer and pro-equipment is drawn in Dutch legislation?
Is, for example, a Behringer mixer pro equipment?

I can hardly imagine it would qualify as such. Mainly because it will be bought for domestic use in 90+% of the cases. The quality would also rule it out for pro use anyway.
As a consequence wouldn't it be consumer audio and therefore qualify for a two year warranty period? Isn't the same thing true for a CDJ 100/200 (not for quality reasons)? Or is it pro-equipment because a manufacturer labels it as such (therefor not having to deal with a longer warranty period)
