TDA7850 power amplifier board 4 channel automotive power amplifier board 4X50W with BA3121 noise reduction

TDA7850 Power Amplifier Board 4 channel automotive power amplifier board 4X50W with BA3121 noise reduction function

TDA7850 automotive power amplifier board
Audio coupling capacitors use the original audio coupler g capacitors
The main filter capacitor adopts the new original 10000uf, which has more energy and lower bass. The main chip TDA7850 uses new original authentic, non-removable grinding parts
With LC filter, more pure power supply, less ripple, less interference, BA3121 isolation noise reduction (eliminate common ground noise)
Reasonable circuit design, no noise when starting, no need to connect the horn protection board 4 input /4 output 12v power supply or use 12v automotive power supply
