Automotive P.A Amplifier.
All project files will be required including, gerber, Altium project, code, firmware for the device.
This project is to design an Automotive P.A Amplifier that will be manufactured
9- 36VDC Input Voltage Permanent
9-36VDC Input Voltage Ignition
Switch mode low heat low power loss xxVDC to 12VDC converter.
12V Output Permanent (Current limited to 6A Max )
12V Output Ignition (Current limited to 6A Max )
2 Microphone Inputs Mono 600 Ohm (Auto mute all sources, MIC always has priority)
Bluetooth Audio Source Input
2 channel Hi-Power Car Radio Audio Source Input
Encoder remote control -> volume turn, long press Power, short press Source select Radio/Bluetooth
2 Channel Audio Output
40W RMS output @ 4 ohm per channel,
Class-D Mosfett to be used.
Optional Ambient noise sensor connector
Design should be optimized for high vibration environment
PCB should be optimized for high production volumes
Design should be done with components that have an estimated availability lifetime of >10 years.
Components where available should have easily replaceable alternatives.
Hi, I read your project description. Your project is really interesting to me and i have many experience working with PCB design, manufacturing functional prototyping with firmware programming, android app, and test. I Daha Fazla
