Electronic Active Crossover CircuitSubwoofer Crossover NE5532 The audible band is in the frequency range 20 Hz to 20 kHz. Signal loud speakers are used, but they are not capable of transferring the entire audible band. Speakers are also used broadband that transmits most of the band but not whole. They still have a problem with low distortion, mini-directionality and sufficient acoustic performance. In the sub is created by the sum of the signals of the right a left channel. Sometimes the input signal is fed to only one channel, but it is loses the ability to create some sounds that are not common to both calles and are transmitted by the second channel.
A block is found behind the census member shows the lower pass filter of the 3rd row. It has a 18dB octave slope. Delving frequency f01 is adjustable from 20Hz to 200Hz. In addition, the subwoofer contains a phase inertor which, serves to optimize the phase characteristic of the subwoofer versus phase satellite characteristics. The switch is used to set the phase shift 0 ° or 180 °. The last branch block is the gain setting circuit. You can set the potentiometer from -20dB to + 20dB. Subwoofer Crossover
Active Electronic Crossover Circuit Schematic
Both the right and left channel channels are the same. The first block shows as in the subwoofer branch of the 3 rd filter, the upper pass. Frequency f01 sa adjusts the subwoofer division frequency. The signal is further divided using the additional 2 bottom and top flow filters. Frequency decomposition is f02, which is fixed at approximately 1.97 kHz. It follows that signal satellites are divided into two channels, one of which transmits lower frequencies and the other higher. Each of these is then fed into blocks that are intended for setup profit. As with the subwoofer, the gain can be set within the range of -20dB to + 20dB. Each channel then has its own output. Together, therefore, there is a switch 2 outputs for each satellite and one for the subwoofer.
