Electronic Circuit Schematic Low Pass Filter for Subwoofer Based on Op-amp TL062

Robometricschool. - There are many electronic circuit schematic that used as Low Pass Filter for Subwoofer this day. In this time we want give you one of the electronic circuit schematic Low Pass Filter for Subwoofer based on Op-Amp TL062.

Electronic Circuit Schematic

Figure 1. Low Pass Filter for Subwoofer using Op-amp TL062 (Image:circuitstoday)

Component List
  1. R1,R2,R3,R4,R5,R6,R7,R8,R9,R10 (see figure 1 above)
  2. C1,C2,C3,C4,C5,C6,C7 (see figure 1 above)
  3. IC1 = TL062

Circuit Performance:
  1. According the electronic circuit schematic likein figure 1, you must provide symmetric power supply +12V, 0V, -12V.
  2. TL062 is a dual high input impedance J-FET opamp which has very low power consumption and high slew rate. The opamp has excellent audio characteristics and is very suitable for this circuit.
  3. The left and right channel are connected to the inverting input of IC1a for mixing. 
  4. The gain of first stage can be adjusted using POT R3.
  5. The output of the first stage is connected to the input of second stage through the filter network comprising of components R5,R6,R7,R8,C4 and C5. 
  6. The second opamp (IC1b) serves as a buffer and the filtered output is available at the pin 7 of the TLC062.
  7. Out of the two opamps inside TLC062, first one is wired as the mixer cum pre amplifier stage.
