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
•
