The Sennheiser EW-DX EM 4 DANTE is four-channel digital wireless receiver with Dante networking capabilities housed in a rugged, all-metal single-rackspace chassis built to withstand the rigors of professional use and rigorously engineered to meet the needs of demanding professionals working in business and educational settings, houses of worship, or on stage.

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 EM 4 DANTE receiver is compatible with the EW-DX bodypack and handheld transmitters and backward-compatible with EW-D components.

• The EW-DX EM4 DANTE 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 87 MHz bandwidth gives you the ability to find a clean channel from 3480 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 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.
• AES-256 encryption keeps your transmissions private and safely protected from unauthorized users.

• The EW-DX EM 4 DANTE 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 four balanced XLR outputs and four unbalanced 1/4" outputs for direct connection to any PA system or mixing board.
• The unit features a built-in universal power supply and comes with a kit for rackmount installation.

• With the Smart Assist app (free download available separately) installed on your Android/iOS phone/tablet, the power of Bluetooth connectivity puts full control of the EW-D EM 4 DANTE right in the palm of your hand. Use your mobile device to connect via Bluetooth for efficient operation and monitoring of your system.
• Sennheiser's Control Cockpit software for Windows allows you to view all the devices across your network, check the microphones in use, monitor battery life, troubleshoot problems, and adjust settings.
• For larger setups, Sennheiser's Wireless Systems Manager provides frequency planning and coordination and real-time monitoring of RF and audio levels. It also allows you to import frequency scans from third-party devices and conduct walk tests and receiver bandwidth scans.
• The system supports third-party interface plug-ins for easy integration into any controlled environment.
• Dante ports allow you to integrate the receiver into your Dante network and distribute the digital audio anywhere you need it in your facility.

• 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; you 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.

Related Questions and Answers

Q: 1. what is the length or dimension of the antenna?

A: The Sennheiser HALF WAVE DIPOLE Half-Wave Antenna Rods for EW-D EM Receiver are 13.5" (344mm) long.

Q: 2. how many handheld mics can connect to this system at the same time ?

A: The receiver will only connect with one mic at a time.

Q: 3. are these antenna compatible with the XSW Band A iem?

A: The Sennheiser HALF WAVE DIPOLE Half-Wave Antenna Rods for EW-D EM Receiver are not intended for use with an IEM transmitter.

Q: 4. Does this output stereo or mono?

A: Hi Joselito - the output for this (and most rackmount wireless systems) is mono; if you have a special application where you'd like to transmit a stereo signal, you would need to have independent transmitters and receivers for your Left and Right Channels, or consider using an IEM System if a bodypack receiver could be used.

Q: 5. what is the gain of the antenna?

A: Regarding the Sennheiser HALF WAVE DIPOLE Half-Wave Antenna Rods for EW-D EM Receiver (Pair, Q: 470 to 550 MHz) and what is the gain of the antenna, it is 2.15 dBi.

Q: 6. Will this plug-in transmitter work with the EW-DX line of receivers? I'd like to replace my EW receivers and SKP2000 transmitte

A: No, the Sennheiser EW-DP SKP Digital Plug-On Wireless Transmitter/Recorder is not compatible for use with the Sennheiser EW-DX series receivers.

Q: 7. Does this fit the new EW-D receiver?

A: The Sennheiser EW-D EM receiver comes with a dedicated rackmount kit for mounting either a single receiver or two receivers together in a standard 19" rack. The GA 4 Rackmount Kit is designed for use with the EM D1 receiver and the dimensions of this receiver are slightly different from those of the EW-D EM receiver. The EM D1 is a bit smaller. At this time Sennheiser does not offer a separate rackmount kit for the EW-D EM since it is included in the box with the receiver. But you can contact Sennheiser directly if you need replacement parts.

Q: 8. Can I use these with an antenna distribution system, instead of the shark fin style? So 4 receivers would be patched into 1 of these antennas...

A: An antenna of this type would not be recommended for a distribution unit. They are designed to be used as a pair with a single receiver, and will not work properly connected to an antenna distro carrying multiple signals.

Q: 9. Can you use this system with an analog EW100 system for panel discussion or is the delay going to cause out of sync problems?

A: The Sennheiser EW-D 835-S SET Digital Wireless Handheld Microphone System has a latency of about 1.9 ms, so the offset will not be substantial when used alongside an analog wireless system.

Q: 10. If used with a the EW-DX EM 4, could use the antennas from the EM 4 by using the RF out of the EM 4 to the RF in on the EM 2?

A: Yes, the RF in of the Sennheiser EW-DX EM 2 DANTE Two-Channel Digital Rackmount Receiver can be connected to the RF out (A and B) of the Sennheiser EW-DX EM 4 DANTE Four-Channel Digital Rackmount Receiver to utilize the 2 x 1/4-Wave Rod Antenna.
