• Wiring Multiple Speakers Using Loop-through:
A loop-through electrical connection is made on the crossover board of the
SF 26X. Connect the wires to the captive screw connectors of the speakers, as
shown below. Be sure to tighten the screws.
NOTES:
• Be sure that the combined impedance of the speaker system does not
equal a value less than the rated minimum load impedance of the
amplifier.
• When a chain of speakers is wired in this configuration, disconnecting one
speaker removes power from the remaining speaker in the chain.

This configuration is useful for troubleshooting in four ways:
• The system is sectioned for easier troubleshooting.
• The source signal can be tested by connecting to the inner + (IN) and inner
– (IN) terminals of the captive screw connector, as shown below.
