General information on the conduit in TCS systems
TCS audio systems
The conduit is determined by structural conditions and only limited by its length.
Observe when selecting the cable length: the
loop resistance must not exceed 20 Ω (table).
To keep the max. permitted loop resistance, the
cross-section of the wire can be doubled, that
means, for one wire two lines are used (illustra-
tion). The lines must be twisted.
When using shielded lines: connect the shields
with each other and connect one side to ground
(b-wire) at the power supply.
Optional star or strand shaped wiring.

6-wire operation
The 6-wire operation is the standard operation mode. Video operation, where two separat-
ed masses (b and M) are used.
The conduit of the lines is defined by the structural conditions and is only limited by length.
