Hi, I have a question about k8030.
If you try to record sth. from a distance, the input record noise amplitude is so small, that you can’t hear anything while playback. So I am wondering how could I amplify the input signal?
I’ve tried to connect the output of the MK136 on the k8030 mike pins and it worked perfectly at first, but now it’s suddenly making strange noises while playing back. I didn’t damage anything, though, because when I remove MK136 and record things normally, everything works fine.
Any ideas how to amplify the signal or why in the combination with MK136 the circuit is acting strange? (when I play the message amplified by mk136, loud and continuous “knocks” (like knocking on the door) are heard from the loudspeaker; even when I record in complete silence!)
