Sennheiser completes the EW-DX line with the EM receiver 4 Dante

With the 19” four-channel receiver compatible with Dante, Sennheiser seeks to create a new standard for wireless microphones. Ideal for live audio applications, tours, transmission, theater and systems integration.

He receptor EW-DX EM 4 Dante completes the offer of Evolution Wireless Digital EW-DX microphones from Sennheiser. The receiver of 4 canales (19”, 1U), network ready, is an ideal choice for anyone specifying or configuring large multi-channel systems in live audio applications, tours, transmission, theater and systems integration.

“With the introduction of the EW-DX, We've created a new standard for wireless microphones and built a worthy successor to our series Evolution Wireless G4”, comments Michael Altemark, wireless product manager, business communication. "With MS 4 Dante, “We have further improved the standard and the EW-DX line is complete.”.

The receiver integrates into existing workflows and infrastructures, offering versatile connectivity through Dante (included AES support 67) for audio over IP, balanced XLR-3 audio outputs and unbalanced ¼” connectors.

“The EW-DX EM 4 “Dante delivers high-quality audio and spectrum-saving equidistant channel spacing in a compact design that system designers and operators require for large wireless configurations.”, afirma Ulf Sikora, Professional Audio Product Manager.

Spectrum friendly operation

EW-DX is another example of Sennheiser's spectrum-friendly product design, brand that distributes Magnetron. Since the systems do not emit intermodulation products, The frequencies can simply be placed in intervals of 600 kHz or intervals 300 kHz in mode

Switching bandwidth 88 MHz leaves a lot of room for maneuver in a congested spectrum and, in ideal conditions, will accommodate up to 146 channels in standard mode (spacing 600 kHz) or until 293 channels in LD mode (spacing 300 kHz).

Ease of use has been a primary objective in the design of the receiver, starting with its auto-switching power supply that adapts to the local power supply. Up to four EW-DX EM can be daisy-chained 4 (until 16 canales) directly without the need for additional devices, since the receiver is equipped with an integrated antenna splitter with antenna feed and signal loop.

For network based systems, The receiver's four network ports allow for flexible configuration modes, and the ports are configured accordingly: Control and primary Dante combined (single cable mode), Separate control and primary Dante (split mode), Control, Primary Dante and Secondary Dante separated (redundancy mode). Ethernet connectivity is IPv4.

Once the receivers have been configured, A quick frequency scan can be initiated via an EW-DX EM 4 Dante. The receiver will automatically implement free frequencies on all connected receivers, including EW-DX EM receivers 2 the EW-DX EM 2 Dante, which saves time and effort. Custom frequency lists can also be loaded into the receiver.

Transmitters conveniently sync via BLE from a distance of up to 20 metros: the operator does not have to crouch in front of the rack to link receivers and transmitters. The parameters to be synchronized can be determined through the receiver menu. The EW-DX receiver also gives you the option to perform a walk test to verify signal integrity on stage or performance area.

For remote control and monitoring, Sennheiser offers network-enabled software such as Wireless Systems Manager o Control Cockpit. Third-party media control systems can also be adapted via the SSC Sennheiser Sound Control protocol.. For small configurations with a maximum of 16 canales, The system can also be operated via the Smart Assist App.

EW-DX EM hospital 4 Dante is well structured with easy access to all functions via the navigation wheel and control buttons, and an OLED display that helps read settings even in less than ideal lighting conditions. In addition to displaying RF levels, a link quality indicator provides information on RF status and a switchable headphone output on the front panel allows monitoring of the audio signal.

Low latency audio

EW-DX uses the high performance audio codec (SePAC) patented by Sennheiser, which guarantees a latency of only 1,9 ms. “This codec has been developed especially for high-quality audio transmission”, emphasizes Sikora. “The quality and clarity of the audio obtained is much better than with standard codecs”. All transmitters have an input dynamic range of incredible 134 dB, eliminating the pressure of having to find the right gain for spontaneous performances or unrehearsed presentations.

In addition to the EW-DX EM 4 Dante, The EW-DX line includes two 19 and a half” two-channel receivers with and without Dante outputs, handheld and pocket transmitters with various microphone options, a wireless table stand, remote and wall mount antennas, as well as a variety of rack-mount and table-mount charging solutions.

“Evolution Wireless Digital EW-DX has been designed with ease of use in mind and offers a complete portfolio to flexibly fit almost any digital wireless microphone need”, concludes Sikora.
