The Sennheiser EW-DP ME4 SET (R1-6) is a comprehensive digital wireless system designed for on-camera use, featuring a cardioid lavalier microphone and operating in the R1-6 frequency band (520 to 576 MHz). This set includes the innovative EW-DP plug-on transmitter/recorder paired with the ME4 cardioid lavalier microphone. The EW-DP unit attaches directly to the camera's hot shoe and connects via a locking 3.5mm cable to the camera's audio input, while simultaneously transmitting the audio wirelessly to a compatible EW-D receiver and recording a backup internally to a microSD card. This dual-functionality provides filmmakers and videographers with a reliable wireless link and crucial audio redundancy in a single device.

The ME4 cardioid lavalier microphone offers focused frontal pickup with good rejection of ambient noise, making it ideal for interviews and presentations in moderately noisy environments. The system delivers the high-quality audio of the EW-DX platform, including 24-bit/48 kHz digital transmission and 128-bit AES encryption. Designed for solo shooters, documentary crews, and broadcast journalists, this all-in-one camera-mount set ensures professional-grade wireless audio capture with the safety net of a local recording, streamlining workflow and de-risking audio in critical shooting situations.
