Subwoofer Filter NE5532 Schematic PCB

On this occasion, I will share the circuit for subwoofer filters in this subwoofer filter different from the previous filter or subwoofer module. In this circuit only use 3 pieces of Op-Amp IC which we usually encounter in tone control circuit, active crossover, a filter circuit, another preamp circuit that is IC NE5532. This IC is very popular so I will apply it to this filter subwoofer circuit and its circuit schematic.
Subwoofer Filter NE5532, Bass Booster
In the above circuit, there are three settings for the subwoofer filter frequency, where the frequency can be filtered from 50Hz up to 300Hz. This frequency setting is on a 50K stereo with a FREQ label, then also there for subwoofer phase settings that we can use ranging from 0 to 180 degrees. Phase settings contained in Phase 100K pot. then the last is the level setting or also can be called the volume subwoofer, which is used to set the amount of voice signal to be transferred to a special power amplifier bass/subwoofer. Level settings contained in the 50K pot Level.

Buy NE5532 IC for this filter circuit from allchips.ai, see image and link below:
To facilitate the making of this filter subwoofer circuit I also share PCB Layout design below, with the size of PCB 107mm x 69mm.
