Series 150W Amplifier With Active Crossover Series 150W Amplifier with Active Crossover is very interesting. Actually, this circuit uses 4-channel power amplifier chip. Well, as an Active Crossover here we use also a chip that can separate the tone of the bass, midrange and treble, the output from the Active Crossover can be directly amplified by power amplifier.

The series of crossover is an electronic circuit in which the point to separate the audio sound frequency. objective that only sound with a frequency range that can be accepted speakers are forwarded. less is more like a filter function, so the speakers work optimally.


2 way or 3 way or else, that determines how many channels would be separated voice. Each channel is handled by a single class of speakers. Eg 3 way, the frequency of sound produced by the head unit, separated by crossover as a low freq (big size distinguished speaker better known as the subwoofer), medium freq (medium speakers), usually in the middle) and hi freq (small speakers I would call a tweeter) Let me better sound and reduce noise.
