I have an Advanced AF3400 with audio warnings that I want to run unmuted to my flightcom 403 intercom. Also I have an SL-40 that I want to run to the 403. Trouble is that the 403 only has one pin (21) to use as input. After searching the internet I could see that some are using a small preamp which supports multiple inputs. But really I dont want another active component (more than enough allready). So I came across a drawing showing that the outputs from EFIS, RADIO ect. can be mixed simply by using a 150 Ohm resistor and 10 uF capacitor in series with each line. Can anyone confirm this will work without doing any harm?
