Sennheiser EW-DX EM 4 Dante: four-channel digital wireless system for professional installations
The Sennheiser EW-DX EM 4 Dante is a four-channel digital receiver designed for professional audio systems that require reliable reception, centralised management and flexible network integration. Installed in a 19-inch rack, it receives signals from transmitters in the Evolution Wireless Digital range and transmits the audio streams to a Dante infrastructure or to compatible equipment in the audio system.
The Q1-9 version covers the frequency range from 470.2 to 550 MHz. Its switching bandwidth reaches 88 MHz. The system is based on the Sennheiser Performance Audio Codec (SePAC), which delivers a claimed latency of 1.9 ms and an input dynamic range of 134 dB. This wide dynamic range reduces the need to adjust the transmitters’ gain according to each speaker’s volume level.
The receiver offers two modes of equidistant frequency spacing: a standard 600 kHz mode allowing for up to 146 channels, and the 300 kHz Link Density mode allowing for up to 293 channels under the conditions specified by the manufacturer. These figures describe the system’s planning capabilities and do not replace the need for an RF survey taking into account available frequencies, existing equipment and local regulations.
Dante connectivity transmits digital audio over Ethernet at 48 or 96 kHz and 24-bit resolution. The four configurable network ports allow you to separate or organise control and primary and secondary Dante streams according to the chosen architecture. Support for IPv4 and IPv6 facilitates integration into professional IT infrastructures. AES-256 encryption protects the wireless link, whilst Dante Media Encryption adds protection specifically tailored to the transport of audio over the network.
The built-in antenna splitter, featuring antenna power and cascade outputs, simplifies the set-up of a multi-channel system. Up to four EW-DX EM 4 Dante receivers can be cascaded via RF, allowing a configuration that can centralise up to sixteen reception channels with the appropriate equipment.
The OLED display, navigation dial, control buttons and headphone output with adjustable volume facilitate local operation. Remotely, the Sennheiser Control Cockpit, Wireless System Manager and SoundBase tools enable the organisation of system control and monitoring. The Smart Assist app also offers Bluetooth Low Energy control at a claimed range of up to 25 metres.
The EW-DX EM 4 Dante Q1-9 is therefore aimed at system integrators, event organisers, theatres, educational establishments and conference venues seeking to streamline a multi-channel wireless microphone infrastructure.

Practical advice and further information:
1. Check the frequency band before purchasing
The Q1-9 variant covers 470.2 to 550 MHz. The associated transmitters must use a compatible band. You should also check which frequencies are actually usable at the site of operation, depending on local regulations and other radio services in the area.
2. Use Link Density mode where the configuration allows
Link Density mode uses a channel spacing of 300 kHz, compared with 600 kHz in standard mode. This may allow for the allocation of more channels, but the number that can actually be used depends on the frequency plan, the RF environment and operating conditions.
3. Utilise the built-in RF cascade
The built-in splitter and BNC outputs allow up to four EW-DX EM 4 Dante receivers to be connected in an RF cascade. This solution can simplify the cabling of a sixteen-channel system, whilst still requiring verification of antenna sizing and frequency coordination.
4. Organise the control and Dante networks separately
The four network ports can be configured for different functions, in particular to separate control from the primary and secondary Dante streams. A redundant architecture must be set up using suitable ports, switches and cabling; the mere presence of multiple ports does not in itself guarantee system redundancy.
5. Monitor link quality using the LQI
The Link Quality Indicator provides additional information at the RF level. It can help identify a degraded link during a walk test, particularly in venues where the movements of personnel alter reception conditions.
