Sennheiser EW-DX SK 3-PIN Digital Wireless Bodypack Transmitter with 3-Pin LEMO Connector (S1-10: 606.2 to 693.8 MHz)

The Sennheiser EW-DX SK 3-PIN is a professional-grade digital bodypack transmitter designed for seamless integration with EW-DX wireless systems. Built with a rugged all-metal housing, it is engineered to withstand the demands of daily use across live productions, conference environments, houses of worship, and stage performances, while remaining lightweight and comfortable for extended wear.

Featuring a 3-pin LEMO input, the transmitter supports a wide range of compatible lavalier and headset microphones, as well as instrument cables for guitars, bass, and other line-level sources. Its impressive 134 dB input dynamic range allows it to handle everything from soft speech to loud vocalists and high-output instruments without requiring manual gain adjustments—ensuring consistent, distortion-free audio in any scenario.

Operational efficiency is enhanced with Bluetooth pairing for quick, reliable syncing with receivers at the push of a button, even at distances up to 120 feet. A persistent e-Ink display provides clear visibility of key parameters and device identification, remaining readable even when powered off. The integrated mute button can be locked or remotely controlled via the receiver or mobile device, offering flexibility during live performances.

Power options include standard AA batteries for up to 8 hours of operation, or the optional BA 70 rechargeable battery pack for extended runtime up to 12 hours. The unit also supports in-device charging via the optional CHG 70N network charging dock, streamlining workflow for multi-device setups.

Leveraging an advanced equidistant tuning grid, the system distributes frequencies evenly across an 87 MHz bandwidth to minimise intermodulation—ideal for dense RF environments. The system supports up to 146 channels in standard mode and up to 293 channels in Link Density mode, making it highly scalable for complex productions. Additionally, the transmitter maintains backward compatibility with EW-D receivers, ensuring flexibility within existing setups.

Compatible microphone options include the MKE 2 omnidirectional lavalier for broadcast-quality audio, the ME 2 for versatile everyday use, the ME 4 cardioid lavalier for improved feedback rejection, and the ME 3 headset for clear speech applications. For instruments, the CI 1 cable enables direct connection to guitars, basses, and keyboards, expanding its versatility across performance and presentation applications.
