3.7.5Tap-offs

The network splitter (LBB4410/00) lets you make tap-offs (refer to figure 3.8 for an example). Tap-offs cannot be redundant. If the cable between the network splitter and the digital audio expander (PRS-4DEX4) becomes defective, the digital audio expander has no connection to the central control unit.
