6 CONNECTIONS
Each connector panel has two Neutrik Speakon connectors wired in parallel
with each other. The second connector allows use of a short link lead to
power another parallel loudspeaker. The connectors are wired as follows:
F8/F10/S12 Passive

7 CABLE LENGTHS
When connecting Blackline systems to an amplifier, it is recommended that
the return resistance of the cable used is less than one tenth of the nominal
impedance of the system or systems in parallel. The table below gives an
indication of the maximum permissible cable runs for various conductor
cross-sectional areas.

8 SYSTEM CONFIGURATIONS
There are many different system combinations possible when the F8 and
F10 full-range systems are used with the S12 and other Blackline sub-bass
systems. Shown below are some typical configurations. The number of F8
or F10 full-range systems required to match the efficiency of one sub-bass
system is shown as a recommended cabinet ratio (RCR). Please note that
for simplicity each line in the diagram represents a pair of wires.
