HO CHI MINH CITY, Vietnam, Sept. 28, 2023 /PRNewswire/ — Audio specialist Sennheiser is delighted to announce the launch of the highly anticipated EW-DX digital wireless microphone series in Vietnam. As part of the Evolution Wireless Digital family, the EW-DX will simplify professional workflows by utilizing refined technologies to deliver a digital UHF system that can be scaled with ease. The complete set of new EW-DX products will include handheld, bodypack and table stand transmitters, two two-channel receiver versions in a half 19″ rack space (one with and one without Dante®) as well as a four-channel Dante-enabled receiver in a full 19″ format.

“This awesome system combines pro features and ease of use in well-designed, rugged housings. We’re happy to see it hitting the market,” says Benny Franke, product manager at Sennheiser. “EW-DX is a more than worthy technological successor to the evolution wireless G4 series and will be setting a new standard in the live audio industry for simplicity, reliability, audio quality and frequency efficiency.”

Stepping up your mic set-up with the latest in digital wireless

Whether for rental companies, touring bands, theatres, worship or broadcasting – EW-DX will simplify workflows and bring an exciting feature set to any application.

Like its EW-D sister models, EW-DX offers the lowest latency on the market (1.9 milliseconds), eliminates the need for frequency calculation, and offers an ultra-wide input dynamic range of 134 dB, enabling your transmitters to handle any signal that is thrown at them. Their operating time is 12 hours with the BA 70 rechargeable battery, which will usually take you through rehearsals and the show or event itself. Operating time with standard AA batteries amounts to eight hours. Depending on the RF environment, the transmitters have a range of up to around 100 m, enough even for very generous stage layouts.

EW-DX systems additionally benefit from an automatic multi-channel RF set-up, scalable remote control and monitoring, as well as AES-256 encryption for secure transmission of contents. The bandwidth is higher than with EW-D, up to 88 MHz, enabling more channels to be accommodated.

Spectrum efficiency and ease of use – how it’s connected

The EW-DX is respectful towards the valuable resource that is the RF spectrum – and takes the complexities out of wireless at the same time. Carefully engineered, the systems do not generate any significant intermodulation products. From a spectrum efficiency point of view, this means that the microphones do not pollute the available spectrum with their own intermodulation products, hence more transmission frequencies can be used and distributed evenly at regular distances (the so-called equidistant frequency grid or tuning grid). A frequency calculation is no longer needed, making your job easier.

Peace of mind instead of frequency calculations: EW-DX does not generate any significant intermodulation products and therefore allows transmission frequencies to be simply placed with equidistant spacing

Ready for the stage – the EW-DX transmitters

EW-DX offers a choice of two bodypack transmitters – the EW-DX SK with a 3.5 mm jack for microphones and instrument cables, or the EW-DX SK 3-PIN for microphones with a special three-pin connector. The bodypacks can be used with any digital-proof Sennheiser clip-on and headset mic, the Neumann MCM system and digital-proof third-party microphones. The handheld microphone is also available in two versions: with a noiseless, programmable mute switch (EW-DX SKM-S) and without a switch (EW-DX SKM). The mute switch can be programmed as ‘off’, AF Mute and RF Mute – the latter enabling you to change settings inaudibly or to keep a spare mic ready for use. A wide range of 14 Sennheiser and Neumann microphone heads (standard Sennheiser capsule interface) is available for the handheld.

All transmitters feature a trim control so they can alternate on the same receiver channel – for example when multiple guitars are used – and still have the same level on the mixing desk. For guitarists and bassists who do not want to miss that typical cable sound, the EW-DX SK bodypack offers a three-step cable emulation.

The EW-DX transmitters are the first on the market to feature e-ink displays and are also fitted with an adjustable low-cut to reduce handling noise, or pop noise in a broadcasting situation. Settings are ‘off’, 30 Hz, 60 Hz, 80 Hz, 100 Hz and 120 Hz. All transmitters feature charging contacts for in-device charging of the BA 70 battery and an in-built test tone generator.

Display brightness can be adjusted, all settings locked, and – an invaluable asset in more intimate stage settings or in a broadcast environment – the green status LED of the transmitters can be turned off.

A star behind the scenes – the EW-DX receiver

The EW-DX EM 2 is the first two-channel receiver to launch in the series. It is an ideal choice for users that do not require a digital audio output, which will become available with the two Dante-enabled receivers soon.

The EW-DX EM 2 is fitted with an Auto Scan function, which will ably assist you in finding good frequencies for your receiver or multiple networked receivers. Transmitters are conveniently synced via Bluetooth® Low Energy: No line of sight is required, no crouching in front of your rack to ensure the transmitters can see the receiver. Even better: you can choose which settings you would like to exchange. If you only want to change a transmission frequency, you can select just that, all other transmitter settings remain untouched.

The receiver is fitted with a headphone output with volume control, both balanced XLR and unbalanced 6.3 mm analogue outputs, and an RJ 45 port for Power over Ethernet and integration into control and monitoring networks. An OLED display shows both channels at a glance, and a link quality indicator helps avoid surprises.

Power to your system – accessories

Until more charging options become available, the two-bay, stackable L 70 USB charger will recharge the BA 70 batteries. This charger is also available in the EW-D charging set, complete with NT 5-20 UCW power supply unit and two BA 70 batteries. Meanwhile, the EW-D power distribution cable and matching NT 12-35 CS power supply unit will power up to four EW-DX EM 2 receivers and keep your set-up cleaner. The EW-D ASA active antenna splitter, EW-D AB antenna booster and ADP UHF passive, directional antenna complete the system accessories that are available now.

Control software

To get the latest firmware updates right from the start, Sennheiser recommends downloading its free Sennheiser Control Cockpit software to a Microsoft Windows computer. Performing an immediate update to the receiver firmware ensures that you will benefit from the full functionality the system can offer. Assistance can be found in this How-to Guide. New versions of the Sennheiser Wireless Systems Manager (WSM, for firmware updates and professional operation) and the Smart Assist App (for convenient operation of smaller set-ups) are now available.
