Sennheiser EW-D ME4 SET Wireless Bodypack System with ME 4 Lavalier Mic

For over 20 years Sennheiser's Evolution Wireless has allowed performers of every type to roam free. The next logical step in that Evolution is the EW-D series, delivered just when we need to roam more than ever!The EW-D-ME4 is a receiver and bodypack set with a Sennheiser ME4 lavalier mic that delivers pure digital wireless audio free from noise, interference, and annoying static bursts. The system's automated setup makes for quick easy implementation with little effort. A dedicated mobile app eschews deep menus giving users a convenient familiar way to operate and change settings.The ME4 clip-on lavalier has a cardioid pickup pattern that rejects sound from the rear and sides to deliver intimate highly intelligible vocals with a slightly enhanced bass response compared to an omnidirectional lav. Whether speaking or singing, they'll be hanging on every word.With over 2,200 selectable frequencies you're never out of range or out of touch. Speaking of range, the EW-D-ME4's 134 dB dynamic range means they'll hear everything you intend, from a whisper to a scream. The bodypack's familiar metal housing reflects Sennheiser's standard rugged design. Operating up to 12 hours per charge when used with the Li-ion battery pack (sold separately) or 8 hours on a pair of AA batteries, you can be sure the show will go on, and on!IncludesEW-D EM rack receiverEW-D SK bodypack transmitterME 4 lavalier microphone(2) Rod antennasPower supply with country adaptersRackmount set(4) Rubber feetQuick guideSafety guideManufacturer declaration sheetFeaturesDigital wireless eliminates noise, interference and static burstsUHF transmission greatly enhances range, reliability and scalabilityMobile App streamlines setup and operation and eliminates complicated menusAutomated setup creates reliable connections with minimal time and effortUp to 2,240 selectable frequenciesLithium Ion battery pack delivers up to 12 hours of operation (up to 8 hours of operation with AA batteries)56 MHz Bandwidth will allow for up to 90 channelsPreserves every detail of even the most dynamic performances with 134 dB transmitter dynamic rangeSpecificationsAudio link frequency rangesQ1-6: 470.2 - 526 MHzR1-6: 520 - 576 MHzR4-9: 552 - 607.8 MHzBluetooth® Low Energy frequency range: 2402 - 2480 MHzAudio frequency response: 20 Hz - 20 kHz (-3 dB) @ 3 dBfsAudio THD: ≤ -60 dB for 1 kHz @ -3 dBfs input levelOperating temperature -10 °C - +55 °C (14 °F - 131 °F)Relative humidity 5 - 95 % (non-condensing)EW-D EM (Rack Receiver)Input voltage: 11 - 13 V ?Input current: ≤ 300 mATransmit power (radiated): BLE: max. 10 mW EIRPAudio output power: 18 dBu max.Dimensions: 212 x 44 x 189 mmWeight: approx. 1000 g (without antennas and power supply)EW-D SK Bodypack TransmitterInput voltage: 2.0 - 4.35 VInput current: < 300 mAPower supply: 2 AA batteries 1.5 V (alkali manganese) or BA 70rechargeable battery packOccupied bandwidth: 200 kHzTransmit power: (radiated) Audio link: 10 mW ERP (Range
