Sennheiser EW-DX EM 2 Dante receiver

The EW-DX EM 2 Dante is a two-channel half-rack receiver in Sennheiser’s Evolution Wireless Digital range. It adds a Dante digital audio output and three network ports to the analog XLR and jack outputs. Power comes from its 12 V supply or from PoE. Showcaller AI connects to the EW-DX EM 2 Dante over your show network through the Bridge App. Then it handles requests for channels 1 and 2 by voice or chat. The Sennheiser EW-DX integration page lists every function.

What Showcaller reads on the EW-DX EM 2 Dante

In every plan, Showcaller reads each channel’s name and mute state, gain and output level. For the transmitter linked to each channel, it reads the type, name and firmware. It also reads the transmitter’s mute state and whether its controls are locked. In addition, Showcaller mutes and unmutes each receiver output, for example before a presenter walks off with a live mic. Then it reads the mute state back from the receiver. The product type, hardware revision and serial number are also available.

Gain, names and frequencies

From the Pro plan, Showcaller reads and sets each channel’s receiver gain in dB. It also names the channels after the people using them. Showcaller reads or changes a channel’s operating frequency in kHz too. However, it asks you before it retunes. Afterwards, it reads the new frequency or name back from the receiver. It reads the transmitter lock state but does not change it. Some features are not offered over the receiver’s third-party interface, so Showcaller does not offer them. These are RF scans, automatic frequency setup, squelch and transmitter mute. Showcaller also cannot rename the device or read battery and RF levels.

Network setup and the plain EM 2

Showcaller controls the receiver, not the Dante audio. It does not read Dante status. Sennheiser offers three network modes on this model: single cable, split and redundancy. In each mode, one port carries Control. So the Bridge App must reach that Control port, not a Dante-only port. Also, third-party access (SSCv2) is off by default, so switch it on with a password first. The plain EW-DX EM 2 has the same two channels but no Dante output and one network port. In Showcaller, both get the same Tool Functions. See the EW-DX EM 2 page for that model. For full specs, see Sennheiser’s EM 2 Dante product page.
