| 3 - System planning
You can compensate this signal loss by configuring the transmission power of the receiver
accordingly. Observe the following minimum transmission power settings (SL Rack Receiver
DW: System Settings menu -> RF Power) for the respective cable lengths. The antenna
splitter causes about as much signal loss as a cable length of 15 m. These losses must be
included in the calculation of the transmission power level.
We recommend the following cable lengths in combination with the antenna splitter:
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 1 m
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 5 m
• Receiver to splitter: 1 m -> splitter to AWM 2/4: 10 m
• Receiver to splitter: 5 m -> splitter to AWM 2/4: 1 m
• Receiver to splitter: 5 m -> splitter to AWM 2/4: 5 m
• Receiver to splitter: 10 m -> splitter to AWM 2/4: 1 m
Cables longer than 10 m are not recommended for this variant.
This results in the following transmission power levels to be set in the menu of the receiver or
simultaneously for all receivers in the Sennheiser Control Cockpit software:
• 5 m cable length plus splitter -> at least level 2
• 10 m cable length plus splitter -> at least level 3
Direct line of sight
• If possible, position the antennas so that there is a direct line of sight (without
obstacles) between the transmitters and the antennas.
