Presonus this year seem focused on building upon their popular range of studio live desks, with a number of new I/O expansion options to help flesh out your setup.

The Presonus NSB 8.8
Designed to work seamlessly with the Presonus StudioLive Series 3 mixers, these two stage boxes allow for easy routing of your audio over standard cat5 or cat6 cable, allowing for less signal degradation over long runs and eliminating large heavy snake runs around the venue.
When setup alongside a Series 3 console, the stage boxes also allow you to remote control them straight from the desk or even from the dedicated touch control app. Featuring locking combo mic/line inputs, XMAX preamps and a pair of AVB connections to allow you daisy chain more units as required, meaning these boxes offer you the flexibility to route and patch your stage to accommodate pretty much any show.
Taking it up a level, the 24R and 32R are more stage box offerings that also function as sub-mixers as well, making ideal for doing secondary monitoring mixes on stage too. Once again you have the full remote mixing capability when hooked up to a series 3 studio live desk allowing you to fully control and customize your scenes and making it just as suitable for long-term shows and installs, as it is for going on tour.
Lastly, we have the EarMix 16M which does away with the stage box functions, making it a hands-on and easy to control 16-way headphone submixer and amplifier.
Each EarMix 16M accepts 16 mono channels of input via AVB networking and can network multiple units with a StudioLive Series III mixer. This allows you to setup up your own custom onstage mix in the headphones, and the line out options also allows you to feed this through to your foldback setup, for a fully custom monitoring arrangement.
