• Up to 12 hours of battery life: Extremely long operating times for full-day lectures or events in combination with the optional BA 70 battery pack.

Professional UHF transmission in the flexible frequency band (U1/5)

The transmitter operates in the license-free UHF frequency ranges from 823.2 to 831.8 MHz and 863.2 to 864.8 MHz, which guarantees you a high range of up to 100 meters and maximum reliability at events. Since frequency requirements can vary depending on the location, the Evolution Wireless Digital series is available in various frequency versions. The model listed here in the combined U1/5 band perfectly covers the common duplex gaps and ISM bands. If you require other frequency bands for your premises, such as Q1-9 (470.2 to 550 MHz), R1-9 (520 to 607.8 MHz), S1-10 (606.2 to 693.8 MHz), S2-10 (614.2 to 693.8 MHz), or Y1-3 (1785.2 to 1799.8 MHz), the configuration can be perfectly adapted to your local RF regulations. This allows you to invest in a future-proof wireless system that can be precisely tuned to your environment.

Maximum dynamics and easy operation without level stress

Thanks to the integrated SePac audio codec, the bodypack transmitter offers an input dynamic range of 134 dB. In practice, this means that you no longer need to make any gain adjustments at the transmitter. Whether it is quietly spoken words during a presentation or loud music passages via the instrument input with cable emulation, the system processes every signal distortion-free and absolutely clearly. With a minimal system latency of just 1.9 milliseconds, the audio transmission takes place practically in real time, which ensures a natural speech feel, especially during live lectures and interactions with the audience. A switchable low-cut filter also reduces unwanted footfall or wind noise in steps from 30 to 120 Hz directly at the source.

Robust housing and smart power management for continuous use

The transmitter features a robust metal housing that easily withstands the harsh demands of daily operation in schools, universities, or conference rooms. A real highlight is the permanent E-Ink display. Parameters such as frequency, channel, and battery status remain permanently readable on the screen, even if the batteries have been completely removed. This makes preparing events as a team much easier. For power supply, you can use either the two included AA batteries or the optionally available BA 70 lithium-ion battery pack, with which you can achieve an operating time of up to 12 hours. The transmitter can also be charged directly in the optional CHG 70N network charger via the integrated charging contacts without having to remove the battery.

Our conclusion: The ideal wireless component for your AV media technology

The Sennheiser EW-DX SK (U1/5) impresses as a reliable UHF bodypack transmitter with its straightforward handling, durable metal housing, and innovative E-Ink display.
