Sennheiser EW-D ME4 SET Digital Wireless Lavalier System (R1-6, 520-576 MHz)

The EW-D ME4 SET pairs Sennheiser's Evolution Wireless Digital transmission with the ME 4 cardioid clip-on lavalier. The cardioid capsule favors the person wearing it and rejects sound arriving from the sides and rear, which controls feedback and room noise where an omni lavalier would struggle. An EW-D EM half-rack receiver and EW-D SK bodypack carry a full 20 Hz to 20,000 Hz over 24-bit digital audio at 1.9 ms of latency. This version is configured for the R1-6 band, 520 to 576 MHz.

Getting on air is a one-button routine: press Sync, the receiver scans its 56 MHz switching bandwidth for a clean frequency, and pushes the setting to the transmitter. The BA 70 lithium-ion pack delivers up to 12 hours of runtime, with AA cells as a fallback for up to 8. The set includes the EW-D EM rack receiver, EW-D SK bodypack, ME 4 cardioid lavalier, two rod antennas, a power supply with adapters, and a rackmount kit.
