Sennheiser EW-D SK (R4-9) Bodypack transmitter Wireless Microphone Receiver
Sennheiser EW-D SK (R4-9) Bodypack transmitter Wireless Microphone Receiver
Versatile and feature-rich digital wireless system for those who sing, speak or play instruments that allows for seamless product pairing and management via the EW-D Smart Assist App. This bodypack transmitter is compatible with a wide range of Sennheiser headset microphones and clip-on/lavalier microphones.
Raising the bar
Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it’s easy to see why this wireless system is in a class of its own.
Equidistant Spacing – simpler than it sounds
Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems. Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies to be equally spaced every 600 kHz alongside each other. This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system’s scalability and impressively high channel count.
An engineer in your pocket
The power of Bluetooth Low Energy puts full control right in the palm of your hand with the Sennheiser Smart Assist app. Take advantage of a remarkably fast automated setup, mobile access to every system setting and the added benefit of remote monitoring, all from the convenience of your Android or iOS device. Save time, save energy and perform with confidence.
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)
