The Sennheiser EW-DPSKP (R1-6) is a sophisticated hybrid device that merges a professional digital plug-on wireless transmitter with a high-quality onboard audio recorder, designed for broadcast, documentary, and film production where ultimate flexibility and backup are critical. Functioning primarily as a plug-on transmitter, it connects directly to the XLR output of a wired shotgun, handheld, or lavalier microphone, converting it into a digital wireless microphone operating in the 520 to 576 MHz range (R1-6). This allows sound mixers to transmit a pristine, secure digital audio signal from the camera-mounted microphone back to an EW-DX receiver, eliminating the need for a cumbersome audio cable between the camera and the microphone and providing freedom of movement for the operator. The digital transmission boasts 24-bit/48 kHz audio quality with extremely low latency and robust resistance to interference, ensuring broadcast-grade wireless audio.

Beyond its core wireless function, the device integrates a professional-grade stereo recorder, a feature that provides a crucial safety backup or serves as a primary recording source for run-and-gun scenarios. It can record the microphone's signal directly to a microSD card in high-quality WAV format simultaneously with wireless transmission, creating an immediate, synchronized backup on location. This dual-functionality is invaluable for high-stakes productions where audio loss is not an option. The unit features a clear, informative color display for monitoring levels, transmission status, and recorder functions, along with intuitive physical controls for gain adjustment, menu navigation, and transport control of the recorder.

Built for the rigors of field use, the EW-DPSKP is housed in a robust, compact body with a secure cold shoe mount for easy attachment to camera hot shoes or cages. It features professional connectors including a 3-pin XLR input for the microphone and a 3.5mm headphone jack for direct monitoring. The unit is powered by a removable NP-F style lithium-ion battery, offering extended operational time and the ability to hot-swap batteries for all-day shooting. With its combination of reliable digital wireless transmission, a built-in safety recorder, and a professional monitoring/control interface, the Sennheiser EW-DPSKP provides sound professionals with an unparalleled tool for increasing production flexibility while guaranteeing audio integrity in any shooting environment.
