Sennheiser EW-D ME4 SET Digital Wireless Lavalier System (R4-9, 552-607.8 MHz)

This is the EW-D ME4 SET in the R4-9 UHF range (552-607.8 MHz), Sennheiser's Evolution Wireless Digital lavalier system fitted with the ME 4 cardioid clip-on microphone. The ME 4's cardioid pattern favors the wearer and rejects sound from the sides and rear, which controls feedback and cuts background noise on a loud stage or in a busy room, so it suits higher-volume live reinforcement, worship, and presentation where gain-before-feedback is the concern.

The digital backbone delivers a 134 dB dynamic range, 1.9 ms of latency, and up to 56 MHz of switching bandwidth to find a clean channel. The EW-D SK bodypack runs up to 8 hours on two AA cells or 12 hours on the optional BA 70 pack and pairs with the half-rack EW-D EM receiver over Bluetooth Low Energy for fast setup. The set ships with the EW-D EM receiver, EW-D SK bodypack, ME 4 lavalier, two rod antennas, power supply, and rackmount hardware.
