Sennheiser EW-DX

Sennheiser has announced that the first EW‐DX devices are shipping in North America, EMEA, Japan, and Singapore. Available products 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 a special 3‐pin mic connector or a 3.5 mm (1/8”) jack for mics or instrument cables. Convenient set packages are available, too, with further, higher frequency variants ready in Q1 2023, and more EW‐DX devices and software being added to the line in mid‐2023.

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.

As part of the Evolution Wireless Digital family, 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.

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 kHzspacing).

And the best thing? This just comes at the expense of approx. 10% of the range, so you will have the same great audio quality and transmission power in LD mode, too.
