Sennheiser 2 channel half-rack Dante receiver EW-DX EM 2 DANTE, 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 EM 2 DANTE is a two-channel digital half-rack wireless receiver engineered for commercial AV, broadcast, and live event installations requiring Dante audio networking and high channel density. Operating in frequency range V5-7 (941.700–959.650 MHz) and requiring an FCC Part 74 license, it is compatible with all EW-DX Series handheld, bodypack, and tablestand transmitters. With 88 MHz switching bandwidth, AES 256 encryption, and PoE power, this receiver integrates directly into Dante-enabled AV system architectures without additional audio interface hardware.

Product Description

The EW-DX EM 2 DANTE half-rack receiver is the network audio centerpiece of the EW-DX wireless platform. Three configurable network modes — single cable (Control, Dante, PoE combined), split mode, and full redundancy mode (dual Dante paths) — allow AV integrators to match the receiver to infrastructure requirements from simple conference rooms to mission-critical broadcast installations. Audio transmission is handled by Sennheiser's SePAC codec, delivering a 1.9 ms wireless latency and 134 dB input dynamic range across both channels simultaneously. Equidistant channel spacing with AutoScan allows fast, intermodulation-free frequency deployment: up to 146 channels in Standard Mode (600 kHz spacing) or 293 channels in Link Density Mode (300 kHz spacing). The receiver is managed remotely through Sennheiser Control Cockpit and Wireless Systems Manager software, and supports third-party integration via Q-SYS, Crestron, and other media control plug-ins. Power is supplied via PoE (IEEE 802.3af/at), eliminating a separate power supply in rack installations. The V5-7 frequency range operates under FCC Part 74 licensing requirements.

Key Features

• Two-Channel Half-Rack Receiver — 9.5-inch half-rack form factor fits standard AV equipment racks alongside companion wireless channels.
• Dante Audio Networking — Three network modes support single-cable simplicity or full redundant dual-path Dante configurations.
• 88 MHz Switching Bandwidth — Supports up to 293 intermodulation-free channels in Link Density Mode for high-density wireless deployments.
• SePAC Codec — 1.9 ms Latency — Proprietary codec delivers broadcast-grade low-latency audio without manual gain adjustment on transmitters.
• 134 dB Input Dynamic Range — Eliminates gain-setting at the transmitter, reducing setup time in multi-speaker commercial deployments.
• AES 256 Encryption — Secures RF transmission for government, corporate, and broadcast environments.
• PoE Power (IEEE 802.3af/at) — Single-cable PoE powers the receiver and carries control and Dante audio simultaneously.
• AutoScan Frequency Deployment — Scans the RF environment and assigns equidistant intermodulation-free channels automatically.
• Third-Party Control Integration — Compatible with Q-SYS, Crestron, and other AV control systems via plug-in.
• FCC Part 74 Licensed Band — V5-7 range (941–959 MHz) is reserved for licensed broadcast and qualified production use.

Frequently Asked Questions

Does the EW-DX EM 2 DANTE require a separate power supply?

No. The receiver is powered via PoE (IEEE 802.3af/at) through its network port, simplifying rack installations and eliminating a separate power brick.

What transmitters are compatible with this receiver?

All EW-DX Series transmitters are compatible, including the EW-DX SK bodypack, EW-DX SKM-S handheld, EW-DX SKP plug-on, and EW-DX SKD tablestand transmitters.

Can this receiver be controlled by a Q-SYS or Crestron system?

Yes. The EW-DX EM 2 DANTE supports third-party control via available Q-SYS and Crestron plug-ins, as well as Sennheiser Control Cockpit and Wireless Systems Manager software.

What is the difference between Standard Mode and Link Density (LD) Mode?

Standard Mode uses 600 kHz channel spacing for up to 146 simultaneous channels. LD Mode uses 300 kHz spacing for up to 293 intermodulation-free channels in dense multi-receiver installations.

Is an FCC license required to operate this receiver?

Yes. The V5-7 frequency range requires an FCC Part 74 license, typically held by broadcast licensees or qualified production organizations.

What Dante network redundancy options are available?

The receiver supports a full redundancy mode with separate primary and secondary Dante paths on dedicated ports, suitable for mission-critical broadcast and live event production environments.
