These crossover are made entirely of passive components and circuitry; the term "passive" means that no additional power source is needed for the circuitry. A passive crossover just needs to be connected by wiring to the power amplifier signal. Passive crossovers are usually arranged in a Cauer topology to achieve a Butterworth filter effect.
Amplifier and loudspeaker with two elements and crossover networks. Top: normal connection. Bottom: bi-wiring. Loudspeaker bi-wired using banana plugs. Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two ...
Bi-amping typically consists of a crossover network and two or more drivers. With ordinary loudspeakers, a single amplifier can power the woofer, mid-range and tweeter through an audio crossover , which filters the signal into high- medium- and low-frequencies (or high- and low-frequencies in 2-way speakers) – a mechanism that protects each ...
In high frequency horns, the L Pad is seen by the crossover, not the amp. L pads may not necessarily use continuously variable rheostats, but instead a multi-position rotating selector switch wired to resistors on the back. Tapped transformers are not L pads; they are autoformers. L pads can also be used at line level, mostly in pro applications.

A crossover cable may also be used to connect two hubs or two switches on their upstream ports. Because the only difference between the T568A and T568B pin and pair assignments are that pairs 2 and 3 are swapped, a crossover cable may be envisioned as a cable with one modular connector following T568A and the other T568B (see TIA/EIA-568 wiring ...
The connector on the Amiga 1000 uses crossover wiring, similar to a telephone handset. The connector wiring on the Apple computers, however, requires a polarized straight-through pinout. Using a telephone handset cable instead of the supplied cable could short out the +5 volt DC supply and damage the Apple computer or the keyboard. [12]
In electronics, a crossover switch or matrix switch is a switch connecting multiple inputs to multiple outputs using complex array matrices designed to switch inputs to outputs such that each output is connected to only one input, but usually inputs may be connected to multiple outputs. There are blocking and non-blocking types of cross-over ...
