Tl072 Subwoofer Circuit Pcb

The supply voltage of the subwoofer filter circuit is symmetrical 2x15v dc pcb has a regulation circuit with a zener diode the value of the limiting resistors 1k 2 2k 3w can be used up to 40 volts in this way the resistance values should be increased for higher voltages.

Tl072 subwoofer circuit pcb.

Subwoofer filter using ic op amp tl072 to enhancing bass amplifier. Since this circuit is designed to operate with a 12 volt dc power. This is circuit of active subwoofer circuit by using x4 ic tl082 or you can using equivalent ic 4558 jrc4558d jrc4558 tl072. Main purpose of this circuit is to provide low frequency output to the amplifier.

The active subwoofer function to filtering bass tones low and add settings for low tones frequency ranging from 20hz up to 70hz on audio signal input output the settings contained in the pot stereo that you can see in the picture circuit schematic. Input voltage 38vdc. 12v symmetrical zenerli regulated circuit max. Subwoofer active filter circuit diagram.

The active subwoofer function to filtering bass tones low and add settings for low tones frequency ranging from 20hz up to 70hz. Audio input is processing on ic tl072 this circuit need voltage supply about 5 15 volt. Nov 29 2016 circuit of active subwoofer circuit by using x4 ic tl082 or you can using equivalent ic 4558 jrc4558d jrc4558 tl072. The transition band of the filter is between about 10hz bottom and 80hz.

2016 sep 23 subwoofer controller uses a single ic tl072 include pcb and regulated power supply circuit for subwoofer controller. Active subwoofer filter circuit based on tl072 opamp is designed for use with power amplifier with good parameters narrow frequency response. But if you put it to use with a home stereo it do not have any rules. Bass sound in the subwoofer is actually due to this circuit the op amp gives the sound with.
