Not sure what you mean. Do you mean that there is an electrical voltage on that input or that when you record, there is a non-zero mean level?

If the latter, then you can always apply a digital filter that takes out ultra low frequencies. > > As I know there is a lot cheap hardware which produces DC Offset. A capacitor removes DC offset. and they are quite cheap. ------------------------------------------------------------------------------ Gaining the trust of online customers is vital for the success of any company that requires sensitive data to be transmitted over the Web.
