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 conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
Tri-amping is the practice of connecting three channels of amplification to a loudspeaker unit: one to power the bass driver , one to power the mid-range and the third to power the treble driver . The terms derive from the prefix bi- meaning 'two', tri- meaning 'three', and amp the abbreviation for amplifier .
Overhead power lines are often equipped with a ground conductor (shield wire, static wire, or overhead earth wire). The ground conductor is usually grounded (earthed) at the top of the supporting structure, to minimize the likelihood of direct lightning strikes to the phase conductors. [ 18 ]
In a typical bi/tri/whatever speaker system, typically a device known as an active crossover sits between the line-level source of each amplifier, taking the full bandwidth line level signal from say a mixing console, as an input and outputting multiple line level signals for input to each of the amplifier/speaker systems.
Power line adapter. Power-line communication (PLC) is the carrying of data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. The line that does so is known as a power-line carrier. In the past, power lines were solely used for transmitting electricity. However, with ...

As of 2022, more than 10,000 power plant and energy storage projects were awaiting permission to connect to the US grid — 95% were zero-carbon resources. New power lines can take 10 years to plan, permit, and build. [33] Traditional power lines use a steel core surrounded by aluminum strands (Aluminium-conductor steel-reinforced cable).
An underground power line provides electrical power with underground cables. Compared to overhead power lines, underground lines have lower risk of starting a wildfire and reduce the risk of the electrical supply being interrupted by outages during high winds, thunderstorms or heavy snow or ice storms. An added benefit of undergrounding is the ...
