how to reduce noises of engine from bus amplifier system? Answered
I am designing an amplifier system for a bus which is serving all passengers like DAEWOO BUS at a time. this system is working good in normal case. but when driver accelerates, the sound of engine is mixed up with audio signal and causes a noise. I don't know how to remove this noises from my amplifier system. One thing to know that a common amplifier TV, and mp3 player is used to amplify audio signals and next individual passenger will be served his headphone/ handsfree as individual headphone jack adjacent to his seat. Also all headphone with all seats are connected in parallel.
I will be thankful if someone help me out in this problem.
