Klark Teknik DN4816U

Adds Ultranet in/out and/or additional USB to the Behringer WING. The unit comes with a mains power adaptor, but it's not necessary as the unit is powered from the StageConnect interface from the desk (if you're using it as a periferal device to a WING, as I am). Plugged it in and it self-configured and "just worked". The Ultranet output doesn't supply the current necessary to self-power a P16-M unit, so you'll need a P16-D if you want to self power a bunch of P16-M devices from the Ultranet output on this device.
