General notes on the cabling in TCS audio systems

The cabling depends on the building situation and is only limited by its length.
• When selecting the cable length consider: the
loop resistance must not exceed max. 20 Ω (ta-
ble)
• To keep within the max. permissible loop resis-
tance the wire cross section can be doubled, i.e.
two lines are used for one wire (figure). The li-
nes must be twisted.
• When using screened cables: connect the
screens to each other and connect on one side
to earth (b wire) on the power supply unit
• Choice of line or star wiring
