Four-channel TDA7388 amplifier board kits (not installed)                

New design is with ACC control inputs by the switch to choose whether to use ACC power control. User-friendly design, easy DIY car audio upgrade modifications friends!

 

The kit uses the original STMicroelectronics (ST brand) of TDA7388 audio amplifier IC,  Hi-Fi level four-channel output. TDA7388 using MOSFET amplification with low distortion, low noise, anti-interference ability, etc., BTL four-channel output, the maximum output power of up to 4 x 41W. This circuit uses a single chip (CPU) to control the sound, and a wide range of applications in car audio, LCD TVs and other products of the electronic volume IC (PTC brand) PT7313 is for volume and sound processing, deep and power, clear treble . Encoder with a push button to select and adjust: treble / bass and total volume, with two external audio signal input from a push button by the CPU control: AUX_1 and AUX_2 input selection (eg: AUX_1 connection DVD audio, AUX_2 connected to a computer or MP3 mobile phones and other audio sources, by selecting the button you can easily convert the input audio signal, without plugging cables). Have two-way audio input, the operation is very simple. 

The single power supply circuit design, DC 12V - 15V (12V battery-powered use can be connected), AC 9V - 12V (Note: The minimum supply current 3A,  It will sound better if use over 3A current)
