The circuit below is a resistor voltage divider circuit which just does about 10 1 voltage attenuation. Let s say you wanted to divide the input signal by 3. Professional audio line level output from your microphone processor is typically 4db.
This circuit is indeed quite simple.
Line level input r1 mic level output r2 ground input ground output r1 33 kohm r2 100 ohm circuit technical data. 47k ω resistor hot output hot pin 2 line level out 100 ω to microphone input low output low pin 3 47k ω resistor. Line level comes in two flavors. This circuit is indeed quite simple.
