5.8.4 KF730P 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.
5.8.5 SB730P Input Connections
There are two 4-terminal barrier strip connectors on
the rear of each SB730P. The connectors are wired
in parallel so that the second connector can be used
to loop the LF1 and LF2 signals to additional
SB730s. The connectors accept stripped wire ends
or wire lugs.
5.8.6 Wire Gauge
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.
