How To Set Up Actice Crossovers
Crossovers are a very important part of the stereo system of the car. They are generally meant to filter the signal by allowing a particular frequency and send it to the amplifier to give a clear audio with maximum clarity. There are two types of crossovers passive and active. The passive crossovers have the possibility of causing loss of volume due to disturbance and are also considered to be hard to control and adjust it. They are placed between the amplifier and speaker. On the other hand the active crossovers remove the line signal and provide a better sound quality. The adjustment of the active crossovers is comparatively easier to adjust. Since the active crossovers play an important role in providing clear audio, this article discusses some directions on how to set up active crossover.
There are few steps with which the question can be answered. These active cross overs are generally used in a car audio system. These also find application in home theater systems and public announcement rigs. A tri amped audio system and a three way active cross over is required to accomplish this task.
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.
Next the band pass filter is set for the system’s midrange speakers. Then the amplifiers are set at low frequencies less than 80 Hertz also it is greater than 3000 HZ.
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.
