Multi-Room Mode setup with SL Multi-Channel Receiver DW
only
For an installation in multiple rooms using only the SL Multi-Channel Receiver DW please observe
the following steps.
Perform these steps room by room subsequently. When you perform the installation and configu-
ration in one room, all devices in all other rooms need to be switched off.
f Install all SL Multi-Channel Receiver DW units of one room to a wall or the ceiling with the front
sides of the receivers facing into the room.
Note: to ensure the Master/Follower functionality the receivers should be installed side to side
and not back to back, as indicated in the following illustration.
Room 2Room 1
f Connect a LAN cable supplying PoE to the Dante I / PoE / Ctrl RJ-45 socket of the first
SL Multi-Channel Receiver DW.
This receiver will become the Master.
f Pair all transmitters.
f Set the RF power level of the receiver to the recommended RF power level according to the
room size as indicated in the Sennheiser Control Cockpit.
f Perform a walktest to ensure the best reception coverage.
f If necessary adjust the RF power level and repeat the walktest for verification.
f Connect a LAN cable supplying PoE to the respective Dante I / PoE / Ctrl RJ-45 sockets of all
other SL Multi-Channel Receiver DW units of the room.
They will synchronize with the Master.
f Set all other receivers to the same RF power level as the Master receiver.
f Switch off all devices in this room before setting up the devices in the next room.
When you are using multiple SL Multi-Channel Receiver DW units, it is possible to dai-
sy-chain the network and audio signals by using the “Single-Cable Mode” (factory default
setting).
PoE will not be daisy-chained, so a PoE injector is required for any additional
SL Multi-Channel Receiver DW.
