Sennheiser EW-DX EM 4 Dante receiver
Showcaller AI reads and controls all four channels of a Sennheiser EW-DX EM 4 Dante by voice or chat. It covers receiver output mute, gain and frequency. It also covers channel names and linked transmitter status.
Overview
The Sennheiser EW-DX EM 4 Dante receiver with Showcaller
The EW-DX EM 4 Dante is the four-channel model in Sennheiser’s Evolution Wireless Digital range. It is a full 19-inch rack receiver with an internal power supply and Dante output. It also has an integrated antenna splitter and four network ports. Showcaller AI connects to it over your show network through the Bridge App. Then it handles requests for channels 1 to 4 by voice or chat. On a four-channel unit, that saves walking to the rack and paging through two front panels. The Sennheiser EW-DX integration page lists every function.
What Showcaller reads on the EW-DX EM 4 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 receiver’s product type, hardware revision and serial number are also available. That helps when several identical EM 4 units share a rack.
Gain, names and frequencies
From the Pro plan, Showcaller reads and sets each channel’s receiver gain in dB. It names the channels after the people using them. Showcaller also reads or changes a channel’s operating frequency in kHz. 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.
Limits and setup points
Some EW-DX features are not offered over the receiver’s third-party interface, so Showcaller does not offer them. These are RF scans and automatic frequency setup, squelch, and transmitter mute. Showcaller also cannot change the transmitter lock, rename the device, or read battery or RF levels. Mute happens at the receiver output.
Two setup points are specific to the EW-DX EM 4 Dante. First, third-party access (SSCv2) is off by default, so you need to switch it on with a password. Second, you can assign each of the four network ports to Control, Dante or both. So the Bridge App must reach a port that carries Control. For full specs, see Sennheiser’s EW-DX EM 4 Dante page.

Connection
Connecting the Sennheiser EW-DX EM 4 Dante receiver
- Control protocol
- Sennheiser Sound Control Protocol v2 (SSCv2), a REST API over HTTPS, through the Showcaller Bridge App
- Enable on the receiver
- Third-party access is off by default. Open Sennheiser Control Cockpit or the receiver's web interface (https://). Go to the network or 3rd Party Access settings and enable SSCv2 (not SSCv1). Set a password of at least 8 characters, mixing letters, numbers and symbols.
- What Showcaller needs
- The receiver's IP address and the SSCv2 password. The username is always "api".
- Network
- Connect a port assigned to Control (Control, or Control + Dante) to the same network as the Bridge App.
- Firmware
- EW-DX firmware 4.x or later
- First check
- Showcaller reads the device info to check the receiver is reachable, then the device name, which needs the password. An authorization error usually means SSCv1 was enabled instead of SSCv2, or the password was not saved.

FAQ
Questions about the Sennheiser EW-DX EM 4 Dante receiver
Can Showcaller mute an EW-DX EM 4 Dante channel?
Yes, in every plan. Showcaller mutes and unmutes each receiver output and reads the mute state back. It cannot mute the transmitter itself, because the EW-DX third-party interface has no command for it.
Why can't Showcaller connect to my EW-DX receiver?
Check that third-party access is set to SSCv2 (not SSCv1) with a saved password. Check that the receiver runs firmware 4.x or later. Also check that the Bridge App reaches a network port assigned to Control, not a Dante-only port.
Can Showcaller read EW-DX battery levels or run a scan?
No. The EW-DX third-party interface does not offer battery or RF level readings, RF scans or automatic frequency setup. So Showcaller does not offer them. Run AutoScan from the receiver or Sennheiser's software.
Can Showcaller change an EM 4 Dante frequency?
Yes, from the Pro plan. It sets a channel's operating frequency in kHz after asking you, and reads the new frequency back from the receiver.
What is the difference between the EM 4 Dante and the EM 2 models in Showcaller?
The Tool Functions are the same. The EM 4 Dante has four channels, so Showcaller addresses channels 1 to 4. The EM 2 and EM 2 Dante have two.
