The Sennheiser EW-D SK is a physical wireless transmitter compatible with the EW-D wireless receiver. Lightweight and comfortable for actors and actresses, this backpack features a sturdy all-metal case that's perfect for everyday use on stage. The
EW-D SK has a locking 3.5mm connector to accommodate your choice of lavalier or headset microphones, or adapter cables for guitar and bass. Its inputs have an excellent dynamic range of 134 dB and can control many sources without further adjustment, including popular singers and actors, instrument connections and even the line signal level from the mixer.
This unit has a sound system that can be turned off and masked by a receiver or cell phone during the show. With the push of a button, it quickly syncs with the receiver via Bluetooth at a distance of up to 120 feet. In addition, the EW-D SK uses a balanced line with a frequency of 2240 evenly distributed over a wide 56 MHz bandwidth to avoid disruptive interference problems when multiple transmitters are powered indoors. The
EW-D SK can be set up and remotely controlled within 120 feet from the receiver via Bluetooth or the Smart Assist app installed on an iOS/Android phone/tablet.
The
transmitter operates for up to 8 hours on two AA batteries or up to 12 hours with the BA 70 Li-Ion rechargeable battery pack (sold separately).
BA 70 battery requires L70 USB Dual Charging Station (sold separately).
Note: The EW-D SK is not backwards compatible with previous evolution systems.
