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.

Conductor CSA	Maximum Cable Run
	4 ohms	8 ohms	16 ohms
1.0mm2	11m	22m	44m
1.5mm2	17m	34m	68m
2.0mm2	22m	44m	88m
2.5mm2	29m	58m	116m
4.0mm2	44m	88m	176m
6.0mm2	66m	132m	264m

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.
