I have connected the board to a 6w amp and speakers,which were tested before playing music from my pc and they performed very well. Now,connected to the dasmikro i have a lot of hishing and maybe clipping or distortion. Is it because of the wires?the motor?the battery? Can i do anything about it or it's just the way it is?
Check the speaker impedance. I dont have the numbers in my head, but with some impedance it worked horrible, and with other it worked flawlessly.
I dont remember now if what you need is 8 ohms or 4 ohms speaker.
I found with the mini, it was CRITICAL and I am sure this is the problem you are experiencing.
EDIT: You need a 8ohm speaker. I had poor result with the 4ohms[/q
i am using an external amplifier with the dasmikro. All the dasmikro does,is sending the sound signal to the channel of the amplifier (audio input),then the amplifier drives the speakers.So, the speaker impedance is not directly related to the dasmikro. If i was connecting the speakers directly on the dasmikro i could see how the impedance could affect it,i dont think it is the problem in my case
