Sennheiser EW-D ME4 SET Digital Lavalier System R4
Versatile and feature-rich all-in-one digital wireless system for those who speak or present that allows for seamless product pairing and management via the EW-D Smart Assist App. With a metal housing, the robust bodypack transmitter and unobstrusive clip-on microphone ME 2 (omni-directional) with high speech intelligibility suit perfectly for daily use on stage.
Features:
- Digital transmission operating in the UHF spectrum greatly enhances range, reliability and scalability
- Smart Assist App connects via Bluetooth Low Energy for a streamlined setup and operation at a distance
- Auto scan creates reliable connections with minimal time and effort
- 134 dB audio input dynamic range eliminates need for sensitivity adjustments and preserves every detail
- Elimination of intermodulation enables channels to be placed in an equidistant tuning grid 600 kHz apart
- 56 MHz of tuning bandwidth and equidistant spacing enables up to 90 channels
- 2,240 selectable frequencies allow for fine tuning
- Lithium-Ion battery pack (sold separately) delivers up to 12 hours of operation (up to 8 hours of operation with 2x provided AA batteries)
