Active subwoofer amp designed for use in the car cabin floor TDA7294 2SC5200 and 2SA1943 used, but the addition of an integrated output power to the output of this circuit is upgraded patlaşıl previously had different PCB drawing ; TDA7294 Power Transistor Output Power Enhancement Supplements
TDA 7294 2x38v DC symmetrical supply is working with cars for use in the TL494 PWM control integrated on the board dcdc converter circuit made additional olrak active bass filter and vu meter circuit well made subwoofer cabinet handmade original from a drawing made already all circuits inside the cabin is mounted
dcdc converter circuit for use in a car is a must but if you use the integrated amp 12v working with do not need or want to use it at home can be operated with normal transformer and rectifier circuit
VU Meter with LM3915 in the TDA7294 amp , TL494 and bass dcdc converter control circuit diagram of PCBs and PCB drawings have cabin dimensional drawing program can open files sprint layout
