Crossover systems

What does a crossover do??

At its simplest form of crossover has two filters. Low pass filter and high pass filters Drive unit of a speaker with frequency range of signal that it can handle effectively and safely. Low pass filter only allow low frequency through to drive the mid-range driver/woofer if a two way speaker system. This can be a passive or an active speaker.

High pass filter only lets the Hugh frequency signals through More Complex systems might ass one or more band pass filters, extraction g a range of mid frequency signals to feed one or more mid-range drivers Some crossover designs are passive and are generally intended to handle a powerful range output signal from A power amp.

The crossover filter outputs the. Feed the corresponding ding speaker drive u it's directly. This kind of arrangement is still very common in my as I've domestic hi-fi speakers Active crossovers Many crossover design are active which means that they are designed to work on line level signals and are used to feed multiple power amplifiers instead of working on the amplified signal. In this situation the active crossover output Fred band limited signals to separate power amps and their respective drive units this kind is arrangement is commonly used in active studio monitors and most big PA speaker system.

The advantage of active crossovers More accurate Cheaper than passive Easier to adjust Versatile The shape, sloping you may get, cuts off are important to matching the characteristics and dispersion of the drive units properly and can vary from first orders Some crossovers also Incorporate delay, to provide time alignment of the drivers and sometimes also phase correction. Most also incorporate protective limiting circuitry.
