Sennheiser SL MCR 4 DW-4 2 Channel Wireless Receiver - 508850

Product Overview

The Sennheiser SL MCR 4 DW-4 is a 2-channel SpeechLine Multi-Channel Receiver designed for professional installed audio in corporate, government, and educational environments. Operating on the interference-resistant 1.9 GHz DECT frequency band, it delivers reliable wireless audio without the spectrum management burdens associated with traditional UHF systems. A single network cable handles both power (PoE) and audio (Dante), making it the most cable-efficient wireless receiver in its class. It is compatible with SL Bodypack DW and SL Handheld DW transmitters and integrates directly into Dante-enabled AV infrastructures.

Product Description

The SL MCR 4 DW-4 2-Channel Wireless Receiver brings enterprise-grade wireless microphone management to rooms that demand reliability and clean installation. Built on Sennheiser's proven SpeechLine platform, the receiver operates exclusively in the 1.9 GHz DECT band—a spectrum that is globally available, license-free, and engineered to coexist with Wi-Fi and other RF systems without interference. Two independent receive channels allow simultaneous operation of two SpeechLine transmitters from a single compact unit that mounts on a wall, ceiling, or microphone stand.

Dante network audio eliminates analog audio cabling runs. A single Cat5e or Cat6 cable delivers PoE power to the receiver while simultaneously carrying up to two channels of lossless digital audio back to the DSP, mixing console, or Dante-enabled endpoint. The integrated auto mixer and analog mix output accommodate legacy analog systems and ensure compatibility with existing DSP installations without requiring hardware changes. AES 256 encryption secures every transmission, meeting the requirements of government, legal, and executive conferencing environments.

Remote management via Sennheiser Control Cockpit software and compatibility with third-party control systems—including AMX, Crestron, and Q-SYS—allows integrators to configure, monitor, and troubleshoot from a central interface. Automatic frequency management and interference avoidance eliminate the need for manual RF coordination, significantly reducing setup time and ongoing maintenance. The user-friendly infrared pairing function creates a verified, encrypted link between transmitter and receiver in seconds. Integrated antennas remove the need for external antenna distribution hardware, reducing both cost and installation complexity.

Frequently Asked Questions

Q: What is the difference between the SL MCR 4 DW-4 and the SL MCR 4 DW?

The SL MCR 4 DW-4 is the 2-channel version of the SpeechLine Multi-Channel Receiver. The SL MCR 4 DW is the 4-channel version. Both share the same 1.9 GHz DECT platform, Dante output, and PoE power design, but the 2-channel model supports up to two simultaneous transmitters while the 4-channel model supports four.

Q: Does the SL MCR 4 DW-4 require a UHF license or frequency coordination?

No. The receiver operates on the 1.9 GHz DECT band, which is license-free in most jurisdictions worldwide. No frequency coordination, frequency allocation software, or RF spectrum management is required.

Q: Which transmitters are compatible with this receiver?

The SL MCR 4 DW-4 is compatible with the Sennheiser SL Bodypack DW and SL Handheld DW transmitters, as well as SpeechLine KIT products that include these transmitter types.

Q: Can this receiver be integrated into an existing Dante network?

Yes. The receiver includes a 2-port Dante interface and connects directly to any Dante-enabled network. Audio channels are routable to any Dante endpoint, including third-party DSPs, amplifiers, and mixing consoles.

Q: Does the SL MCR 4 DW-4 work with Q-SYS, Crestron, or AMX control systems?

Yes. The receiver supports remote control and monitoring via third-party media control platforms including Q-SYS Control, AMX, and Crestron, in addition to native Sennheiser Control Cockpit integration.

Q: Is an external antenna distributor required for installation?

No. The SL MCR 4 DW-4 features integrated antennas, eliminating the need for external antenna distribution hardware and simplifying ceiling or wall mounting.

Q: What does DDM Ready mean for the SL MCR 4 DW-4?

DDM (Digital Dante Monitor) compatibility means the receiver can be monitored and managed through Sennheiser's network-wide monitoring tool, providing real-time status of all connected devices on a shared Dante infrastructure.

Q: How is the receiver powered?

The receiver is powered via Power over Ethernet (PoE) through the same Cat cable that carries Dante audio. No separate power supply or power outlet at the mounting location is required.
