Crossovers

Crossover:

You will find a Crossover is a part of most live events and is usually found on a rack-mounted box with the amplifiers. Signals are sent from the mixing desk into the crossover which splits signals into two or more frequency bands e.g. Hi’s and Lows. Depending on the crossover for example if you had two inputs and four outputs you could then send the two hi outputs into the treble amp and two low inputs into the bass amp.

You can get crossovers in many different ways such as 2-way, 3-way stereo or 4-way mono.

The crossover also has mute switches for the Hi’s and Low’s on each Input so you can check individual (Bass Bins / Mid Tops) to make sure they are all working. You can also cut or boost the Low Frequencies, Mid / Hi Frequencies and sweep through the range of frequencies on each input.

Low Frequencies; 20hz – 180hz

Mid – Hi Frequencies; 180hz – 20khz

The crossover splits them twice so you will get a Low Frequency and Mid – Hi Frequency from each input. The crossover has been created to split these frequencies to prevent damage to the speakers and monitors that may not be able to support the frequencies provided by the signal.
