Sennheiser has announced that the first EW-DX wireless systems are shipping in North America, EMEA, Japan, and Singapore, with available products that include the EW-DX EM 2 two-channel receiver, the handheld transmitter – with or without programmable mute switch – and the bodypack transmitter.
The latter also comes in two versions, either with 3-pin mic connector or a 3.5 mm (1/8 in) jack for mics or instrument cables. Set packages are available as well with further higher frequency variants slated to be ready in Q1 2023 and more EW-DX devices and software being added to the line in mid-2023.
“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 a 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.”
The EW-DX offers stated low latency (1.9 milliseconds), is designed to eliminate the need for frequency calculation, and offers a stated wide input dynamic range of 134 dB. Operating time is specified 12 hours with the BA 70 rechargeable battery, while operating time with standard AA batteries amounts to eight hours.
EW-DX systems additionally offer 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.
In standard mode – i.e., with an equidistant frequency spacing of 600 kHz – EW-DX accommodates up to 146 links within its switching bandwidth and up to 293 frequencies in Link Density Mode (LD, at 300 kHz spacing). The company states that this is attained with only a loss of approximately 10 percent of range. j
“The Link Density Mode will give you even more room to manoeuvre in a densely populated RF spectrum,” Franke says. “The slight reduction in range is barely noticed during productions. EW-DX will give you peace of mind, knowing that audio quality and transmission power will not suffer. Signals will sound great, and will be reliably transmitted.”
EW-DX offers a choice of two bodypack transmitters – the EW-DX SK with a 3.5 mm jack for microphones and instrument cables and the EW-DX SK 3-PIN for microphones with a 3-pin connector. The bodypacks can be used with any digital-proof Sennheiser clip-on and headset microphone, the Neumann MCM system and digital-proof third-party mics. 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 users to change settings inaudibly or to keep a spare mic ready for use. A range of 14 Sennheiser and Neumann microphone heads (standard Sennheiser capsule interface) is available for the handheld.
All transmitters include 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.
EW-DX transmitters are also equipped with e-ink displays – even when switched off, users are still be able to read off essential transmitter data. They 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. And, all transmitters have 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 the green status LED of the transmitters can be turned off.
