Professional UHF transmission in the U1/5 frequency range

A stable connection forms the foundation of every successful event. The Sennheiser EW-DX SKM-S wireless microphone transmitter operates in this version in the flexible and, in many regions, license-free UHF frequency band U1/5, which covers the ranges 823.2 to 831.8 MHz and 863.2 to 864.8 MHz. This frequency grid, in combination with the high RF power of 10 mW, enables a reliable transmission range of up to 100 meters in open areas. A special technical advantage is the equidistant frequency grid with spacings of 600 kHz, which consistently eliminates intermodulation between multiple transmitter components. This allows numerous channels to be operated in parallel even in dense wireless environments, without the need for complex frequency calculations. You thus get future-proof scalability for growing setups.

Maximum dynamics and flexibly adjustable audio functions

Crystal-clear sound without annoying noise or clipping significantly increases intelligibility at lectures and concerts. With an impressive input dynamic range of 134 dB, the handheld transmitter effortlessly handles even extreme volume peaks without you having to manually adjust the input sensitivity. For precise adaptation to the respective room acoustics, a switchable low-cut filter is available to you, which effectively reduces low-frequency noise such as footfall noise at 30, 60, 80, 100, or 120 Hz. The integrated digital audio trim function and the test tone generator additionally support you in quick commissioning. An integrated, programmable mute switch on the housing also allows the speaker to mute the AF or RF directly to avoid unwanted side noises during speaking pauses.

Robust metal housing and smart power management

The demanding everyday event environment requires durable components that can be relied on in every situation. The handheld transmitter is made in an extremely robust metal housing and easily withstands mechanical stress during continuous use. The innovative E-Ink display permanently shows you parameters such as frequency, channel, and battery status – these values remain readable even when the device is switched off or the batteries have been removed. In terms of power supply, the system shows itself to be flexible: The transmitter can be operated either with two classic AA batteries or with the optionally available lithium-ion battery pack BA 70, which enables an extended operating time of up to 12 hours. Via the integrated charging contacts, the transmitter can also be charged directly in the separately available network charger CHG 70N.

Our conclusion: Why the EW-DX SKM-S is the ideal choice for your events

The Sennheiser EW-DX SKM-S handheld transmitter in the U1/5 frequency band impresses as a professional tool for conferences, stages, and educational institutions. By dispensing with manual gain controls and providing an intermodulation-free frequency grid, the system minimizes the setup effort to a minimum. The resilient metal housing, the long battery life of up to 12 hours, and the permanent E-Ink display guarantee economical and low-maintenance long-term operation.
