Equipped with a robust metal housing and flexible control options, this handheld microphone is optimally designed for daily, intensive use in educational institutions, businesses, or on stage. Discover the benefits of precise digital wireless transmission for your events.

Your Benefits at a Glance

• UHF frequency range R1-9: Operation in the spectrum from 520 to 607.8 MHz for reliable and long-range signal transmission.
• 134 dB input dynamic range: Distortion-free audio recording without manual level adjustment thanks to the SePac audio codec.
• Permanent E-Ink display: Important parameters such as channel and battery status remain visible even when the device is switched off.
• Up to 12 hours of operating time: Reliable availability over long event periods when using the optional BA 70 lithium-ion battery.

Maximum dynamics and stable signal transmission in the R1-9 frequency band

Clear and dynamic voice transmission forms the foundation for successful presentations and moderations. The Sennheiser EW-DX SKM Handheld Transmitter (R1-9) uses a wide audio frequency response from 20 Hz to 20 kHz to reproduce voices faithfully and with rich detail. Thanks to the integrated SePac audio codec, the system features an input dynamic range of 134 dB. In practice, this means that the transmitter handles extreme differences in volume without you having to manually readjust the gain settings on the microphone. The signal always remains clear and protected against clipping. The digital system latency of just 1.9 milliseconds also ensures virtually delay-free lip synchronization, which is particularly crucial for live broadcasts and video conferences. With an RF transmission power of 10 mW ERP, the transmitter reliably covers an operating range of up to 100 meters in the R1-9 band. This allows you to benefit from a stable connection and high planning security, even in larger event spaces.

Maximum flexibility through capsule compatibility and ergonomic design

Different spaces and speakers often require different microphone characteristics to effectively minimize disruptive background noise or feedback. The EW-DX SKM Handheld Transmitter features a standardized capsule interface, allowing you to quickly change the microphone head. You can flexibly equip the transmitter with a wide range of Sennheiser and Neumann capsules – such as the MMD 835 or MMD 845 dynamic modules – and thus perfectly adapt the microphone to the local acoustic conditions. The durable metal housing reliably protects the sensitive technology inside from mechanical impacts in the demanding everyday event environment. With its compact dimensions of 40 x 200 mm without the module, the transmitter lies comfortably and balanced in the hand. Directly on the handheld microphone, you have full access to all transmitter settings via the integrated function buttons. A switchable button lock reliably prevents parameters from being accidentally changed during a performance.

Efficient power management and continuous status monitoring

Nothing is more critical during an ongoing event than a sudden battery failure or uncertainty about the remaining operating time. To prevent this, the handheld transmitter is equipped with a permanent E-Ink display. It shows you important status information such as frequency, channel, and the exact battery status – even when the device is switched off or the batteries have been removed. For power supply, you can choose between the two AA batteries included in the delivery or opt for the optionally available BA 70 lithium-ion battery. In combination with the BA 70 battery, the transmitter achieves an extended operating time of up to 12 hours, ensuring that even all-day conferences are safely covered without intermediate charging. Thanks to integrated charging contacts on the bottom of the housing, the transmitter can also be charged directly in the optional CHG 70N network charger without having to remove the battery. A digital low-cut filter, which can be flexibly switched in steps between 30 Hz and 120 Hz, rounds off the equipment and eliminates disruptive footfall or handling noises before transmission.

Our conclusion: The reliable component for your wireless audio setup

The Sennheiser EW-DX SKM Handheld Transmitter (R1-9) proves itself as a professional tool for demanding audio applications in the frequency range of 520 to 607.8 MHz. The combination of the high dynamic range of 134 dB, the minimal latency of 1.9 ms, and the flexible capsule interface guarantees you excellent speech intelligibility and maximum flexibility at every event.
