Overview:
The Sennheiser EW-DX SK is a digital bodypack wireless transmitter compatible with EW-DX wireless receivers. Lightweight and comfortable for performers and presenters to wear, the bodypack features a rugged, all-metal housing well suited for daily use in conference rooms, houses of worship, or on stage.
The EW-DX SK is equipped with a locking 3.5mm TRS connector that accommodates the compatible lavalier or headset microphone of your choice, or an adapter cable for guitar and bass. With a remarkable 134 dB dynamic range on its input, the transmitter can handle a wide variety of sound sources, including loud vocalists and performers, connections to musical instruments, and even line-level signals from mixers, all without requiring any gain adjustment.
Features at a Glance
- The EW-DX SK features a mute button that can be locked out and overridden from the receiver or a mobile device during a performance. It quickly pairs with the receiver via Bluetooth at a distance up to 120', at the press of a button.
- The persistent e-Ink display helps you quickly name and identify the transmitter and allows you to see parameters, even when the unit is powered off.
- The transmitter provides up to 8 hours of operation on two AA batteries (included) or 12 hours with a BA 70 lithium-ion rechargeable battery pack (available separately). External charging ports allow for in-transmitter charging using the CHG 70N network charging dock (available separately).
- The EW-DX system utilizes an equidistant tuning grid that equally spaces 3200 frequencies across its wide 80 MHz bandwidth to prevent disruptive intermodulation issues that occur when multiple transmitters operate in confined spaces.
- The system can be expanded with multiple transmitters and receivers to offer up to 134 channels in equidistant tuning grid mode, and up to 269 channels in Link Density mode.
- The EW-DX SK is backward-compatible with EW-D receivers.
Compatible Mics and Instrument Cable with Locking 3.5mm TRS Connector
- The sweat-resistant, subminiature MKE 2 omnidirectional lavalier mic offers a pristine, broadcast-quality sound and is easy to conceal.
- The unobtrusive ME 2 omnidirectional lavalier mic provides a forgiving pickup pattern that captures sound equally well in every direction.
- The ME 4 cardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
- The ME 3 cardioid headset mic provides enhanced speech clarity for lectures and presentations.
- The CI 1 instrument cable lets you connect the bodypack transmitter to a guitar, bass, or keyboard.
