how to reduce noises of engine from bus amplifier system?
Is the bus petrol or diesel?Hi all,
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.
Should be possible to buy a suppressor kit for the alternator.thanx for reply!
the bus has diesel fuel.
by grounding with chassis, not a good noise reduction.
should I use any filter design to remove engine noise from the audio? then how can I do?
Try reading post#7 again.hi, thanx MIkeML for your valuable opinion.
Already we have done common grounded with bus body using a choke filter which is used in Tube Lights. it works well but not satisfactory. it recomended by a professional working in electronic market.
I want to get ride off from this choke like solutions. I want to solve this problem using an efficient amplifier r filtering design. If, in your opinion, it is possible and affordable by involving a small circuitry then I should do this, otherwise go on an old solution.
Also I m not willing to use suppressor kit etc............!
