In a distribution amplifier, plug-in modules or jumpers are essential components for determining which secondary downstream output ports are active. These modules or jumpers can be used to configure the amplifier's output settings based on specific requirements, allowing flexibility in how signals are routed to various downstream connections. By utilizing these components, the technician can enable or disable different outputs, effectively managing signal distribution and ensuring that the correct ports are active for their intended purpose.

Patch cables play a different role. They are typically used for connecting devices rather than for configuring output ports. Multi-switch boxes serve a distinct function in switching signals between multiple sources and destinations but do not directly control the activity of output ports on a distribution amplifier. Signal analyzers are tools for measuring and analyzing signals rather than for determining the activation status of output ports. Therefore, the role of plug-in modules or jumpers is pivotal in managing output configurations in distribution amplifiers, making them the correct choice in this scenario.
