About Sennheiser EW-DX MKE 2/835-S

- EW-DX EM 2 Rack Receiver -
The Sennheiser EW-DX EM 2 is a half-rack, dual-channel digital wireless receiver compatible with EW-DX SK bodypack, EW-DX SKM handheld, and EW-DX TS tabletop transmitters. Housed in a rugged, all-metal chassis built to withstand the rigors of professional use, it can either sit on a tabletop or be rackmounted (with the included rackmount set) for portable rigs and permanent A/V installs.

The wide 80 MHz tuning range, intelligent switching diversity, auto-scan, equidistant tuning grid, and Link Density mode work to provide rock-solid wireless performance and massive channel counts, even in challenging RF environments. Bluetooth capabilities allow you to remotely sync components and change settings from your phone using the Smart Assist app, while Sennheiser's Control Cockpit and Wireless Systems Manager software provide computer-based control for more extensive networked setups. The EW-DX EM 2 receiver is backward-compatible with EW-D components.

Reliable Wireless Performance with More Channels via Link Density Mode
• The EW-DX EM 2 operates in the UHF band, far away from potential Wi-Fi interference in the 2.4 GHz band.
• The UHF transmission greatly enhances range (up to 330') and the wide 80 MHz bandwidth gives you the ability to find a clean channel from 3200 available frequencies.
• Intelligent Switching Diversity offers effective protection against multipath and other anomalies that cause RF interference. The system compares incoming signals on two independent antennas and receiver circuits to ensure optimal wireless quality. The receiver switches between antennas only during header data as to never affect the audio information.
• Sennheiser's equidistant tuning grid removes the need for frequency coordination and enables you to operate up to 134 mic channels simultaneously.
• For complex systems requiring even more mics, engage the Link Density mode for up to 269 channels on the same system.
• AES-256 encryption keeps your transmissions private and safely protected from unauthorized users.

Easy-to-Use Receiver with Fast and Intuitive Interface
• The EW-DX EM 2 receiver offers intuitive front-panel controls and dual high-contrast OLED screens with meters for RF, battery status of the associated transmitter, and audio output that make setup a breeze.
• The auto-scan function automatically seeks out the cleanest available frequency for you.
• The receiver pairs with the transmitter via Bluetooth from up to 120' away, enabling you to quickly pair the mic directly from the stage without having to bring it close to the receiver.
• The back panel houses two balanced XLR outputs and two unbalanced 1/4" outputs for direct connection to any PA system or mixing board


- EW-DX SK Bodypack Transmitter -
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 (available separately) or 12 hours with a BA 70 lithium-ion rechargeable battery pack (included). 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.


- EW-DX SKM-S Handheld Transmitter with MMD 835 Capsule & Mute Switch -
The Sennheiser EW-DX SKM-S is a digital handheld wireless transmitter/mic compatible with EW-DX wireless receivers. Well suited for a wide range of professional performance and presentation applications, the transmitter features a programmable mute switch and an MMD 835 dynamic capsule with a cardioid pickup pattern that focuses audio capture on the talent in front of the mic capsule, helping to minimize noise and feedback. Lightweight and comfortable for performers and presenters to hold, the transmitter features a rugged, all-metal housing built to withstand daily use on stage.

Features at a Glance
• With a remarkable 134 dB dynamic range on its input, the EW-DX SKM-S can handle a wide variety of sound sources, including loud vocalists and performers, all without requiring any gain adjustment. A trim control allows you to adjust the level for group performances.
• The included MMD 835 capsule is a dynamic capsule with a cardioid polar pattern that rejects off-axis sound, helping to focus audio capture on the presenter or performer and reducing feedback issues when monitor speakers are used.
• The transmitter is equipped with a programmable mute button that can be locked out and overridden from the receiver or a mobile device during a performance.
• The e-Ink display helps you quickly name and identify the transmitter and allows you to see parameters, even when the unit is powered off.
