ITEM NAME:DC12V TDA7850 Car Audio Power Amplifier Board Stereo 4x 50W with BA3121 Denoiser DC12V TDA7850 Car Audio Power Amplifier Board Stereo 4x 50W with BA3121 Denoiser Description: TDA7850 amplifier board car latest version with BA3121 common ground noise, with ACC function control (sound enhanced version) ST's TDA7850 is a high-quality Hi-Fi car audio amplifier IC, using a single power supply 12V - 14.4V supply, MOSFET amplifier output, 4 x 50W HiFi amplifier, low distortion, low noise, anti-interference ability, with output short circuit and temperature protection in particular aspects of performance particularly prominent power, low power consumption, stable, sound quality is excellent. For car audio upgrade and DIY 4-channel amplifier the best choice. HIFI concept design can be used for multi-channel production, with super good noise performance chip BA3121, effectively eliminating the common ground noise, TDA7850 and BA3121 can be a perfect match. ACC function control Introduction: Amplifier board ACC interface with vehicle ACC control line connecting (on-board computer better wiring), ACC signal control amplifier working and standby. Standby current is about 12 mA, basically not much power. The amplifier board there is a delay function, there is no impact sound, without adding speaker protection class. The board features: 1: The 25v8200UF large pond filter capacitor, more deep bass. To play the superior sound quality of the amplifier using a range of audio fever capacitance capacitors ELNA blue robe BP Promise fever, red WIMA Weimaraner fever audio capacitors, nichicon golden audio capacitors. 2: All new original authentic materials, non-polished material used disassemble, to optimize the adjustment on the original official line, no impact sound switch. 3: LC filter, power more pure, ripple smaller, less interference serpentine traces, sound more mellow, high-current traces strengthen tin for the high current state stable solid foundation. 4: With BA3121 .Find many great new & used options and get the best deals for DC12V TDA7850 Car Audio Power Amplifier Board Stereo 4x 50W with BA3121 Denoiser at the best online prices at Order2india Shopping!
