Audited Supplier Fever class TDA7850 power amplifier board 4 channel car power amplifier board 4X50W with BA3121 noise reduction
TDA7850 car power amplifier board
Audio coupling capacitors use original audio coupling capacitors
The main filter capacitor uses a new original genuine 10000uf, more energy, bass is more low. The main chip TDA7850 adopts new original genuine, non-disassembled grinding parts
Using LC filter, the power supply is more pure, the ripple is smaller, the interference is smaller, and the BA3121 isolation noise reduction (elimination of common ground noise)
The circuit is reasonable in design, no noise when starting up, no need to connect the horn protection board 4 input / 4 output
DC 12V power supply or use 12V automotive power supply
There is no impact sound with delay function, no need to install horn protection
