Sennheiser Digital wireless lavalier set with EW-DX EM 2 receiver, 2x EW-DX SK bodypack, 2x MKE 2 lavaliers, frequency range: V5-7 (941.700-951.800 & 953.050-956.050 & 956.650-959.650). Part 74 license required.

Product Overview

The Sennheiser EW-DX Digital Wireless Lavalier Set delivers a complete two-channel UHF wireless solution engineered for demanding commercial AV, broadcast, and live production deployments. Designed around the EW-DX EM 2 half-rack receiver with dual EW-DX SK bodypacks and MKE 2 lavalier microphones, this set operates in frequency range V5-7 (941.700–959.650 MHz) and requires a Part 74 license. With AES 256 encryption, Dante audio networking, and up to 293 intermodulation-free channels, it is suited for corporate event production, house of worship, government, and broadcast studio installations where channel density and network integration are priorities.

Product Description

The EW-DX ecosystem is built around Sennheiser's proprietary SePAC (Sennheiser Performance Audio Codec), delivering a 1.9 ms wireless transmission latency and 134 dB input dynamic range — eliminating the need to manually set gain on transmitters in the field. The included EW-DX EM 2 receiver is a two-channel 9.5-inch half-rack unit that supports Dante audio networking with three configurable network modes: single cable (Control, Dante, PoE), split mode, and redundancy mode for mission-critical installations. An 88 MHz switching bandwidth allows frequency coordination across large multi-channel systems, with AutoScan deploying equidistant channel spacing automatically. The two EW-DX SK bodypacks support in-device charging and deliver up to 12 hours of battery operation per charge. Each EW-DX SK bodypack pairs with an MKE 2 omnidirectional lavalier, a miniature condenser capsule proven across broadcast and live production environments. AES 256 encryption secures all RF transmission. Remote system monitoring and control are available through Sennheiser Control Cockpit, Wireless Systems Manager, and third-party control systems via plug-in. The set operates in the V5-7 frequency range and a Part 74 FCC license is required prior to deployment in the US.

Key Features

• AES 256 Encryption — End-to-end RF encryption protects audio transmission in government, corporate, and broadcast applications.
• 134 dB Input Dynamic Range (SePAC) — Sennheiser's proprietary codec eliminates the need for manual gain setting on bodypacks in the field.
• 1.9 ms Wireless Latency — Ultra-low latency is suitable for IEM-monitored live production and broadcast workflows.
• 88 MHz Switching Bandwidth — Up to 293 intermodulation-free channels available in Link Density (LD) mode with 300 kHz equidistant spacing.
• In-Device Charging + 12-Hour Runtime — EW-DX SK bodypacks charge inside compatible charging slots with a full-day runtime per charge.
• AutoScan Frequency Deployment — Automatically scans the RF environment and deploys clean frequencies with equidistant spacing.
• MKE 2 Lavalier Microphones (×2) — Miniature omnidirectional condenser lavaliers included, field-proven in broadcast production environments.
• PoE Power Supply — Redundant power via Power over Ethernet (IEEE 802.3af/at) simplifies rack and infrastructure cabling.
• 9.5-Inch Half-Rack Form Factor — Two-channel receiver fits standard equipment racks alongside other wireless channels.

Typical Applications

• Boardroom and executive conference room wireless microphone systems

Frequently Asked Questions

Does this set require an FCC license?

Yes. Operation in the V5-7 frequency range (941–959 MHz) requires an FCC Part 74 license. This is typically held by broadcast licensees and qualified production companies.

What Dante network modes does the EW-DX EM 2 support?

The receiver supports single cable mode (Control, Dante, and PoE on one cable), split mode (Control + PoE on one port, Dante daisy chain on another), and redundancy mode with primary and secondary Dante paths for mission-critical installs.

How many channels can be coordinated in this frequency range?

Up to 146 channels in Standard Mode (600 kHz spacing) or up to 293 intermodulation-free channels in Link Density (LD) Mode (300 kHz spacing).

Is the system compatible with third-party control platforms?

Yes. The EW-DX EM 2 integrates with Sennheiser Control Cockpit, Wireless Systems Manager, and third-party media control systems via available plug-ins, including Q-SYS and Crestron.

Can the bodypacks be charged in a rack-mounted charger?

Yes. The EW-DX SK bodypacks support in-device charging and are compatible with Sennheiser's CHG 2 and L 2015 charging solutions sold separately.

What is the warranty on this system?

Sennheiser provides a standard 2-year warranty on EW-DX products. Extended coverage options may be available through your dealer or Sennheiser support.

Where can I find compatible accessories for this system?

Antennas, antenna splitters, chargers, and cables compatible with the EW-DX ecosystem are available at creationnetworks.net/collections/sennheiser.
