The Sennheiser SL MCR DW is a versatile receiver designed to handle both analog and digital audio signals, offering flexible connectivity and control options for professional audio environments.

Function Description

The primary function of the SL MCR DW is to receive audio signals and output them in either analog or digital formats. It supports Power over Ethernet (PoE) for power supply, simplifying installation by eliminating the need for a separate power cable. The device can be controlled and monitored via a network using Sennheiser Control Cockpit software, providing comprehensive management capabilities.

Usage Features

Audio Output:

The receiver provides a 3-pin Analog Out socket for analog audio output, compatible with Phoenix Contact MCVW 1.5-3-ST-3.81 connectors. For digital audio, it features a Dante™ interface with two RJ-45 sockets (Dante I and Dante II), supporting redundant output for enhanced reliability. These Dante ports also facilitate network control and configuration.

Power and Network Connectivity:

The Dante II / PoE / Ctrl RJ-45 socket serves multiple purposes: it provides PoE supply for powering the receiver, acts as a digital audio output, and enables configuration and control via the network. This integrated approach streamlines cabling and setup. The receiver automatically powers on when PoE is supplied, and there is no separate on/off switch.

Control and Monitoring:

The SL MCR DW is primarily operated and configured using the free Sennheiser Control Cockpit software, which can be downloaded from the Sennheiser website. This software allows for comprehensive control and monitoring of the receiver via a network, eliminating the need for direct interaction with the device itself. The online help within the software provides detailed information on its functions and how to configure the SL MCR DW and the network. A one-time registration with an email address is required to receive the software activation code.

Status Indicators:

The receiver features status LEDs that provide visual feedback on the device's operational status and the status of individual microphone channels.

• Device Status (all LEDs):
  • All LEDs green: Device is starting (approx. 20 seconds).
  • All LEDs flashing red: Indicates a device error, with details available in the Control Cockpit.
  • All LEDs flashing yellow: The device is performing a firmware update.
  • All LEDs flashing green: The "Identify" function for the entire device has been initiated in the Control Cockpit.
• Individual Channel Status (per LED):
  • LED green: A radio link to the transmitter is established.
  • LED flashing red: An error has occurred in this channel, with details shown in the Control Cockpit.
  • LED red: No radio link to a transmitter.
  • LED yellow: The received transmitter has been muted with the MUTE switch.
  • LED flashing yellow: A firmware update is in progress on the received transmitter.
  • LED flashing green: The "Identify" function for this channel was initiated in the Control Cockpit.
  • LED flashing red and green: Pairing mode is active for this channel.

Mounting Options:

The SL MCR DW offers flexible mounting options to suit various installation needs:

• Wall Mounting: The receiver can be mounted on a wall using the supplied mounting frame. It is crucial to use appropriate screws and anchors for the specific wall characteristics. A minimum distance of 1.5 m from other walls and the ceiling should be maintained. The mounting frame has a "top" marking that must be correctly aligned to prevent the receiver from falling out.
• Ceiling Mounting: Similar to wall mounting, the receiver can be mounted on the ceiling using the supplied mounting frame, maintaining a minimum distance of 1.5 m from walls.
• Stand Mounting: The mounting frame includes a 3/8" thread, allowing it to be mounted on a standard microphone stand.
• VESA Mounting: The mounting frame features holes positioned 100 mm apart, enabling it to be mounted on any VESA 100 mount using four suitable screws. In all mounting scenarios, the receiver is inserted into the mounting frame until an audible "click" confirms it is securely in place.

Maintenance Features

Firmware Updates:

Firmware updates for the receiver are performed using the Sennheiser Control Cockpit software. Detailed instructions for this procedure can be found in the software's instruction manual, available in the Sennheiser Documentation app or the download area of the Sennheiser website.

Reset Functionality:

A "Reset" button is provided on the device to restore factory settings. This button should be held for 5 seconds to initiate the reset process.

The SL MCR DW is designed for professional use, offering robust audio capabilities, simplified power and network integration, and comprehensive remote management through dedicated software. Its flexible mounting and clear status indicators contribute to its ease of use and reliability in various audio setups.
