Bass Filter Circuit Diagram. If you want to plan to imply this 4558 ic circuit for bass and treble both then this is not the right circuit. Let s go to watch the video.
If we use this circuit in our amplifier as a preamplifier then we can get the only bass from the amplifier. The filter circuits actually attenuate all the frequency and hence the output filtered low frequency signal need to be amplified by the following amplifier circuit. The filter is sometimes called a high cut filter or treble cut filter in audio applications.
The post explains a simple low pass filter circuit which can be used in conjunction with subwoofer amplifiers for acquiring extreme cuts or bass in the frequency range 30 and 200hz which is adjustable.
The circuit has two pots one for volume adjustment and another to adjust the filter cutoff frequency of 50 to 150hz if you need to install the pots in a panel use shielded wires to make connections. For more information just check passive low pass filter. It s an active subwoofer circuit diagram. Here in this circuit we can input the audio as audio r and audio l and we can get the output as audio r and audio l.
