• What is the difference between Master and Follower receiver?

  • To get the maximum number of microphones it is necessary to synchronize them with each other. Therefore, a master is needed, which controls all other microphones (follower).
    If you are using SL MCR DW the Master/Follower set up is done automatically.
    
    If you are using only SL Rack Receiver DW please follow the steps below to ensure a valid Master / Follower configuration for your system:
    
    - Prepare and connect the antennas (if needed with AMW 4 and combiner)
    - Switch on one receiver and pair a transmitter. Wait until the LED at the receiver turns to green. This microphone will become the Master.
    - Switch on all other receivers, while the Master receiver is still on. All other microphones will become a follower automatically.
    
    IMPORTANT: As soon as the Master / Follower configuration has been done all receivers have to be switched on at the same time e.g. via a power strip.
