An electronic crossover is a device that is used to separate a single input signal into multiple output signals consisting of separated bands of low-, high-, and mid-range frequencies. These different frequencies are distributed over different speakers in a sound system consisting of subwoofers, tweeters and woofers.
Crossovers can be found in almost any type of speakers. For example, if your home theatre uses two-way speakers, it has an in-built 2-way crossover within the speaker box. The high-pass crossover block low frequency notes from channeling it to tweeter, while a low-pass filter passes the low frequency notes on to the sub-woofer.
An electronic crossover offer many features. Below is a small description of few of the important features that you should consider to make an informed decision when shopping for an electronic crossover.
Frequency – The frequency refers to the point where you’d like the signal to start drop off for the filter. For instance, to achieve a low pass crossover, especially for the woofer, you can set the frequency to 100Hz. This means that frequencies above 100Hz will start to crossover or drop in level.
Bass Boost – This is an important feature that provides a boost to low frequency sound signals. At center frequency, you achieve the strongest boost. Some electronic crossovers include a ‘Q’ adjustment which levels the width of frequencies mostly mixed-up by the bass boost.
Output Level – This control is used to configure the output level of the crossover channel such as sub-woofer, front speaker or rear speaker.
Multiplier – This switch is used to make appropriate changes in the range of frequencies usually experienced through the frequency control option that we discussed above.
Function of Electronic Crossover
Without a crossover, it is difficult to properly channelize high and low sound frequency to the respective tweeter and the subwoofer in a speaker system. Imagine a tweeter exposed to low sound frequency (Bass), it will certainly get destroyed. If a sound frequency goes in the wrong lane, it can damage your set of good speakers.Crossovers can be found in almost any type of speakers.

Uses of 3-Way Electronic Crossover
A 3-way electronic crossover is used for a lot of different purposes such as it can be seen in:- Subwoofer integration that have the remote capability
- Digital analyzers
- Digital equalizers
- In home theatre systems
- In combo amps
- In car audio
