Thanks for clearing that up for me. Could there be a detrimental effect if the coupling capacitor was not used during troubleshooting, I am guilty of doing it sometime back.A capacitor is used to inject a test signal into a circuit in order to trace what is working and what isn't.
The reason for a capacitor is you do not want DC currents flowing between your signal source and the circuit under test.
The capacitor is called an AC coupling capacitor.
You want a capacitance value that is not too small and not too large, since you are essentially creating a high pass filter.
A low capacitance (under 100nF) poorly passes low frequencies. The sound will be very tinny.
A high capacitance (over 10μF) will pass more low frequencies but also could carry a large charge around which we don't want.
Remember, this is just a temporary test. We don't care too much about the voltage rating and polarity at this point. A non-polar 1μF capacitor will do fine.
Yep not directly related to Tapco Thump.If your question has nothing to do with the Tapco Thump we can change the title of the thread.
If you do not use a coupling capacitor you are at risk ofThanks for clearing that up for me. Could there be a detrimental effect if the coupling capacitor was not used during troubleshooting, I am guilty of doing it sometime back.
So using a polarized cap with either polarity should not be an issue right? In case a non-polar cap is not available on hand at that moment.
Should I be using a coupling capacitor always? For eg: Say I was injecting some audio from my phone output to a node in the preamp section or the power amp section?
Thanks
