9.9 System limits
• The total cable length (using standard LBB 4116/xx cable)
between the central control unit and the last unit in any
branch of the system must not exceed 250 m (820 ft 2 in).
This includes all extension cables and the 2 m (78.74 in)
long cable attached to each system unit
• The total length of the extension cable from the central con-
trol unit to the first regenerative tap-off (i.e., from Trunk
Cable Splitter LBB 4114/00, Audio Media Interface Unit
LBB 3508/00 or Extension Power Supply Unit
LBB 4106/00) must not exceed 100 m (328 ft 1 in)
• The total length of the extension cable between regenerative
tap-offs outputs must not exceed 100 m (328 ft 1 in)
• The maximum distance between table-top contribution units
is normally 160 cm (62.99 in). This distance can be
increased by using the LBB 4116/xx Extension Cable
Assembly
Examples
The examples given below of the LBB 3500/xx,
LBB 4106/00 and LBB 3508/00 show the following:
• Maximum number of units that can be connected to
a single output
• Maximum number of units that can be connected to
all outputs
• Maximum cable length from an output to the last unit
In these examples, the following annotations are used:
TT

= Table-Top Discussion Units

DAI = Dual Audio Interface Unit
MPC = Multi-Purpose Connection Unit
CON = Concentus Units
It can be seen by the maximum number given for each
type of unit that a Table-Top Discussion Unit requires
less current than a Dual Audio Interface Unit or a
Multi-Purpose Connection Unit, and therefore more
Table-Top Units can be connected to central control
equipment. Concentus Units require more current than
the above mentioned units.
LBB 3500/15, 35 power capacity identical to LBB 4106
power capacity.
