The Sennheiser EW-DP SKP is a sophisticated and versatile digital plug-on transmitter that also functions as a standalone audio recorder, operating in the R4-9 frequency band (552 to 607 MHz). This device is designed to connect directly to the XLR output of a professional camera or mixer, converting the wired audio signal into a secure, high-quality digital wireless transmission for an EW-D series receiver. Simultaneously, it can record the audio internally to a microSD card, providing a critical backup or primary recording in a compact, self-contained unit. This dual functionality makes it an indispensable tool for broadcast journalists, documentary filmmakers, and solo shooters where audio redundancy and wireless flexibility are paramount.

The transmitter features a full-color touchscreen interface for intuitive control over settings, monitoring, and file playback. It supports 24-bit/48 kHz digital audio transmission with 128-bit AES encryption and records in high-quality WAV or compressed formats. Powered by a rechargeable lithium-ion battery, it offers extended operation and can also pass phantom power to the connected microphone. By combining reliable wireless transmission with fail-safe recording in a single device, the EW-DP SKP significantly de-risks field audio capture, ensuring that critical sound is never lost, whether transmitted wirelessly or recorded locally.
