Overview
 
Rigorously engineered to meet the needs of demanding professionals working in business and educational settings, houses of worship, or on stage, the Sennheiser EW-DX MKE 2 SET  is a dual-channel digital UHF wireless system with an impressive feature set designed to simplify your workflow while delivering uncompromising audio quality. This configuration includes a dual-channel, 1/2-rack receiver and two bodypack transmitters with subminiature MKE 2 omnidirectional lavalier mics.
 
Features
 
Rock-Solid Wireless Audio with Professional Digital Sound & More Mic Channels
 
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 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.Â
The equidistant tuning grid removes the need for frequency coordination and allows you to add additional transmitters and receivers for 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.
 
2 Bodypack Transmitters with Mute Switches, e-Ink Displays, and MKE 2 Omni Lav Mics
 
The two rugged, all-metal compact bodypack transmitters are equipped with lockable mute buttons along with function buttons that allow you to control all the transmitters' settings directly from the device.
The sweat-resistant, subminiature MKE 2 lavalier microphones offer a pristine, broadcast-quality sound and are easy to conceal. They feature forgiving omnidirectional pickup patterns that capture sound equally well in every direction, for a consistent voice level, even when moving your head. The lavs plug into the locking 3.5mm connector on the bodypack transmitters, ensuring that they don't detach at a critical moment.
The persistent e-Ink displays help you quickly name and identify the transmitters and allow you to see parameters, even when the units are powered off.
Each transmitter will operate on its included BA70 rechargeable battery for up to 12 hours. Two AA batteries will power the transmitter for up to 8 hours. Charging contacts allow for in-device battery charging with the CHG 70N (available separately).
 
Dual-Channel Receiver with OLED Screen & Bluetooth
 
The all-metal, 1/2-rack, dual-channel EW-DX EM 2 receiver offers intuitive front-panel controls and a high-contrast OLED with meters for RF, battery status of the associated transmitter, and audio output that make setup a breeze.
Bluetooth capabilities allow you easily sync transmitters at a distance of up to 120' away and control the receiver remotely from your smartphone using the Smart Assist app.
The RJ45 port allows for PoE (Power over Ethernet) as well as networked control via Sennheiser's Wireless Systems Manager and Cockpit Control software.
Balanced XLR outputs as well as unbalanced 1/4" outputs provide plenty of connection options for PA systems and recording equipment. A front headphone jack with volume control is also provided, along with an external PSU if you're not using PoE.
A rackmounting kit is included.
In addition to the bodypack transmitters and MKE 2 lavs included with this system, Sennheiser offers a number of separately additional transmitter and mic options for the EW-DX system as your needs evolve.
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.
The EW-DX SKM handheld transmitter is available either with or without a mute switch. The interchangeable capsule design allows you to use a variety of optional dynamic and condenser mic capsules, with pickup patterns ranging from wide omnidirectional to narrow supercardioid—capsules include the MMD 845, MME 865, MMD 935, MMD 945, MMD 42, MM 435, ME 9004, MD 5235, ME 5004, and Neumann KK204 to name a few.
For conferences and meetings, the EW-DX TS is a tabletop transmitter that provides a stable base for gooseneck microphones and is available with 3-pin or 5-pin XLR inputs.
 
To maximize the reliability of the system, consider upgrading the included antennas.
 
The rear-mounted, 1/4-wave detachable antennas can be upgraded to longer, 1/2-wave dipole antennas (available separately) for added range and reliability; users can also choose an ADA UHF Active Antenna or the AWM Wallmount Antenna as well.
For setups with multiple receivers, the EW-D ASA Splitter allows you to split and distribute a dual-antenna signal across 4 receivers for clearer reception without the intermodulation problems that can occur when multiple antennas are used.
