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 SK-SKM-S BASE 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 1/2-rack, dual-channel receiver, one bodypack transmitter without a lavalier, and one handheld transmitter without a mic capsule—so you can choose your preferred lav mic and mic capsule for the application.

With a remarkable 134 dB dynamic range, the transmitters can handle just about any input level you throw at them. The wide 87 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 is backward-compatible with EW-D components.

Rock-Solid Wireless Audio with Professional Digital Sound & More Mic Channels

• The UHF transmission greatly enhances range (up to 330') and the wide 87 MHz bandwidth gives you the ability to find a clean channel from 3480 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. 
• The equidistant tuning grid removes the need for frequency coordination and enables you to operate up to 146 mic channels simultaneously.
• For complex systems requiring even more mics, engage the Link Density mode for up to 293 channels on the same system.

1 Handheld Transmitter without Mic Capsule

• This set provides two transmitters, the first is a handheld transmitter without a mic capsule, so you can choose your preferred capsule for the application.
• 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 835, 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.
• The rugged, all-metal transmitter is equipped with lockable mute buttons along with function buttons that allow you to control all the transmitter's settings directly from the unit.

1 Bodypack Transmitter without Microphone

• This set also provides an all-metal bodypack transmitter with function controls and a locking 3.5mm input jack to accommodate your choice of compatible lavalier mic, headset mic, or guitar cable.
• The e-Ink displays helps 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 a transmitter for up to 8 hours. Charging contacts allow for in-device battery charging with the CHG 70N (available separately).
• Input trim controls allow you to adapt individual transmitters for group performances.

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.

Add Functionality with Additional Transmitters, Mics, and Accessories

In addition to the bodypack and handheld transmitter/mic included with this system, Sennheiser offers a number of separately available transmitters and mic options for the EW-DX system as your needs evolve.

• The EW-DX SK bodypack transmitter is also available with a 3-pin LEMO connector.
• 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 four receivers for clearer reception without the intermodulation problems that can occur when multiple antennas are used.
