车的声音与温度的保护（G-501D)

car audio Temperature protection model: G-501D 1. With a boost power circuit design, its output power is 100W RMS; 2. With a built-in MP3 player, it can support standard USB interfaces of SD/MMC cards; 3. Panel and external connection remote signal input; 4. It has an RCA and 3.5MM stereophonic standard interface which makes it convenient to connect CD and external MP3 players; 5. It is equipped with a high pitch output port; 6. With built-in acoustic compensation circuits, it is fairly perfect in degree of balance of high, medium, and low pitch; 7. Over wide working voltage (12V system: 10V-16V; 24V system: 20V-32V); 8. With an ergonomic low-voltage protection function, it can prevent excessive drain on the battery, leaving one unable to start their vehicle; 9. With an overvoltage protection function, it will shut down automatically when supply voltage is higher than normal value; 10. Output short-circuit protection circuit can prevent machine burning caused by short circuiting of the output line; 11. With a temperature protection function, it will automatically stop working when the temperature is higher than 90°C and automatically recover after the temperature falls; 12. Using high-precision components and fully-automatic paster manufacturing engineering, it has better consistency and higher reliability.
