The Sennheiser EW-DP ME2 SET (R4-9) is an integrated camera-mount wireless system designed for videographers and filmmakers, combining wireless transmission with local backup recording. Operating in the R4-9 band (552 to 607 MHz), the set includes the EW-DP plug-on transmitter/recorder and the discreet ME2 omnidirectional lavalier microphone. The EW-DP unit mounts directly to the camera's hot shoe, receives audio from the lavalier, transmits it digitally to a compatible EW-D receiver, and simultaneously records a backup copy to a microSD card. This dual functionality provides a crucial safety net for audio capture in unpredictable field production environments.

The ME2 lavalier is a miniature electret condenser microphone known for its natural sound reproduction, ideal for interviews and spoken word. The system delivers the high-fidelity audio of the EW-DX series, including 24-bit/48 kHz transmission and secure encryption. Designed for solo operators and small crews in documentary, news, and event videography, this all-in-one package streamlines the workflow by eliminating separate recorders and cables, ensuring professional wireless audio is captured with redundancy directly at the camera.
