This compact and rugged transmitter is designed to be worn by a performer, converting an analog audio signal from a connected microphone, instrument, or other source into a secure, high-fidelity digital wireless transmission. It features a robust metal casing, a clear OLED display for monitoring settings and battery status, and a locking connector for secure attachment of lavalier microphones or instrument cables. The transmitter is powered by two standard AA batteries, offering extended operational time.

This bodypack utilizes the advanced technology of the EW-DX platform, including 24-bit/48 kHz digital audio transmission for pristine sound quality, ultra-low latency, and 128-bit AES encryption for secure communications. It is designed to pair seamlessly with EW-D series receivers. Whether used with a lavalier mic for presenters, a headset for vocalists, or a direct input for instrumentalists, the EW-D SK bodypack provides performers with reliable, cable-free mobility without compromising on the audio quality demanded by professional broadcast, theater, and live sound environments.
