Amplifier Crossover Circuit Diagram. For splitting the signal you can use resistors for basic splitting. One stage is tuned to the low frequency band and other is tuned to the high frequency band respectively.

Lm833 is a dual operational amplifier especially designed for audio applications. Passive crossover circuit uses passive components only and they are very simple but they waste a considerable amount of energy. This is the simplest type of network usually found in budget.

The circuit can be divided into two parts a high pass filter section and a low pass filter section.

Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal. And the frequency exceeds 3khz is the high frequency. The circuit can be divided into two parts a high pass filter section and a low pass filter section. Passive crossover circuit uses passive components only and they are very simple but they waste a considerable amount of energy.
