    Audio input Audio board

    Dear all,,

    I use the audio board with sgtl5000, my short wave receiver produce CW signals so weak signal are very good but strong signals make errors.

    So the audio input is then to high for the board..... we can use a pot but in this case not possible because the signals are fluctuating from very low to strong signal. Low is not signal is not the problem but to high input gives problems.

    Is there any solution that I not overload the audio board?

    Any help is more then welcome!

    Best regards,

    If it’s only about cw “beeps”, you might limit the signal with two antiparallel diodes and a resistor.
