The Hive Industries (Interspace Industries) MicroCue3 MC3-L3 is a wireless presentation cueing system for conferences, product launches, lectures and events where a presenter needs reliable control of slides running on up to three computers at once, such as main and backup playback machines. The MicroCue3 base unit has three USB ports, each connecting to a separate computer as a standard keyboard device, with front-panel buttons that select and show the status of each connection. This MC3-L3 package includes one 3-button handset with laser pointer, providing Next, Back and Blackout buttons, with signal-strength and battery-condition indication. On the rear, two XLR connectors link units over Interspace's i2Net network (tested to 1,500 m), so several MicroCue3 units can be chained to drive up to 12 computers from one click for multilingual or multi-graphics shows. Hive's system listings note that each main unit ships with three USB-A to Micro-USB cables. It is a robust alternative to consumer clickers for professional technical desks.
