Guide To Adjust A JL Audio Amplifier Input Sensitivity
Audio systems have become a part of household devices. Hence has resulted in the emergence of companies which produce such systems. JL audio is one of the manufacturers of quality electronic audio products. Their products include audio systems for home, mobile and marine. They are well known for their subwoofers, subwoofer amplifiers and audio crossovers. This article reads on how to adjust a JL audio amplifier.
Amplifiers need to be set properly for the proper output. The following paragraphs will give you the clear picture of fixing the amplifier and adjusting it to obtain the best music.
A high frequency or a low frequency may cause damage to the amplifier. Thus it is understood that these frequencies has to be avoided from reaching the amplifier. The filter used for the above purpose is called the crossover filter.
The first step is to determine the permissible frequency ranges. These are called cross over frequency. They act just like filters filtering low and high frequency sound signals from reaching the car speakers. The low tones or bass are usually removed by high pass filter and trebles or higher tones are eliminated or removed by low pass filter. Next we have to decide whether we have to fix the cross over at high pass filter or low pass filter. This is determined by what the amplifier powers. It can be small speakers or even sub woofers. In the former case we go usually for cross over fixed at HPF. If amplifiers powers a woofer we may fix the cross over to low pass.
It is observed that small speakers are being powered by amplifiers, as in the case of car dash. In the above case, a high pass crossover filter is set. After that, the frequency is set to 100 Hz. It is also seen that subwoofers are powered by amplifiers. In this case, a low frequency crossover filter is set. Similarly as that of the other one, the frequency is set to 100 Hz. The frequencies can be adjusted according to one's wish using the settings available in the JL amplifier.
The amplifier's bass boost is then set. This is the next thing to be done. This bass boost comes as an in built feature of few audio's manufactured by JL groups.
Some music lovers will want to hear the lowest music also. This is achieved by setting the bass control in the amplifier. It is present in a few amplifiers and hence used to make music sound better. This control is adjusted so as to get the desired music, especially when we use speakers and subwoofers.
Thus we have learnt How to adjust a JL audio car amplifier by ourselves to tune the amplifier to enjoy our taste of music.
