Overview
The EW-DX EM 4 Dante is a four channel digital wireless receiver in a single 19 inch rack unit, built for installs and production racks that run audio over the network. All four channels go straight onto Dante, and the internal power supply takes an IEC mains lead, so there are no wall warts to manage behind the rack.
The antenna splitter is built in, with antenna power and a loop through, so one pair of antennas feeds all four channels. Cascade up to four EM 4 receivers from the same antennas for 16 channels without buying a separate splitter. It suits churches, conference venues, schools and corporate AV fit outs where the mixer or DSP already lives on a Dante network, as well as hire companies building fly packs. FFP supplies Australian legal bands and can advise which one suits your venue.

Forefront Tip
Set up the Dante network before you scan for frequencies. Run Dante primary and secondary on separate switches if the venue supports redundancy, and keep control on its own port. Mount the antennas front of rack or remote them with GZL RG 58 cable and an AWM 2 or ADP UHF paddle so they can see the stage, then run AutoScan with all transmitters off. Pair it with EW-DX SKM handhelds or EW-DX SK bodypacks on the same band.
