5.8.4KF730P Input Connections

There are two 4-terminal barrier strip connectors on the rear of each KF730P. The connectors are wired in parallel so that the second connector can be used to loop LF and MF/HF signals to additional KF730s. The connectors accept stripped wire ends or wire lugs.

The maximum recommended loudspeaker cable lengths for each wire gauge are based on maintaining an acceptable damping factor and minimizing power loss at the nominal load impedances listed. While wire gauges smaller than those listed may be used, damping factor reductions and power losses may become significant. The table includes the overall nominal load impedances where the subsystems in multiple enclosures are wired in parallel to one amplifier channel.
