Multi-Room Mode setup with SL Rack Receiver DW only

When installing SpeechLine Digital Wireless in several rooms, it is crucial that you perform the following steps one after the other and room by room. When installing SpeechLine Digital Wireless devices in one room, all devices in all other rooms must be switched off.

  1. Install all receivers in a room in one rack (see Installing receivers in a rack).
  2. Connect all cables for the receivers (see Connecting the receiver).
  3. Make sure to power all receivers via a multiple socket with a central power switch.
  4. Mount all antennas as recommended and feasible (see Recommendations on antenna mounting).
  5. Ensure that all receivers are switched off.
  6. Switch on the first receiver. This receiver will become the Master.
  7. If necessary, pair a transmitter. Only if necessary, as the sets are delivered already paired.
  8. Set the RF power of the receiver to the recommended RF power level according to the room size as indicated on the receiver UI or in the Sennheiser Control Cockpit.
  9. Power cycle (switch off and on again) the receiver to verify the selected value.
  10. Perform a walk test to ensure the best reception coverage (see Performing a walk test (reception quality)).
  11. If necessary adjust the RF power level and repeat the walktest for verification.
  12. Make sure to leave the Master receiver switched on for all following steps.
  13. Then, switch on all other receivers. They will synchronize with the Master.
  14. Set all other receivers to the same RF power level as the Master receiver.
  15. Power cycle the other receivers. The Master receiver must be switched on all the time.
  16. Once the rack is configured, all devices must be switched off/on together every time via the central power switch of the multiple socket.
  17. Make sure not to switch any receiver on or off individually.
