The following article shows how to set an active crossover. They are important for all audio system. By means of frequency the signals are filtered and for better clarity they are directed to the best amplifier and speakers. Generally any car audio system should have an active crossover to be used. They are also used in public meetings and in theatres mostly. An audio system namely the tri-amped is an active crossover and is needed to install the crossovers.

A three way crossover is typically used for audio systems in car. Therefore for setting up active crossover, the following things will be required: three way active crossover, a tri amped audio system, and few basic tools.

Next the audio signals are connected from the crossover’s inputs of the audio system to the stereo unit. Each crossover band’s outputs are connected to the respective amplifier. Path between subwoofer amps and low signal is routed. For the tweeters high signals are routed.

Then all the possible electrical connections are made. The crossovers run approximately for a dc voltage of about 12. A suitable connection to the battery is needed. Suitable Ground line should run to car’s chassis. Connection to the electrical signal which is switched by means of ignition should also run. It is done to prevent the battery getting drained while the car does not run. To know about wiring instructions, the literature should be consulted as it is a vital part in making the connection work properly.

The required electrical connections are made. Since the crossover uses twelve volt direct current connection it needs a connection with the battery. Additional connections are to be made to the chassis of the car for the ground line. It is advisable to connect to the electrical signal that is switched on by the ignition. This ensures that the battery is not drained.

The low pass of the crossover is set at 8o Hz. This ensures that sound below this frequency is passed to the subwoofer amplifier. The high pass is set at 3000Hz. This passes the sound above this frequency to the tweeters.

The next step is to set band pass filter. This is set between the low and high pass.

Cross overs can be used for increasing the quality and clarity of sound but the question how to set up active cross overs makes it look like a big task but by following these simple steps one can easily accomplish the task.
