Splitter for mic in Cessna 206

[mxl]

I am flying a Cessna 206 that has 2 sets of audio input (headphone and mic) for passengers behind the front seats. However, as I intend to carry 4 passengers, I have decided to use an audio splitter (Hosa Y cable 1/4 in TRS to dual 1/4 in TRSF) in order to allow audio to be transmitted to 4 headsets. However, I can’t seem to find a solution to split the microphone port? So that the remaining passengers can also have microphone input. I have tried looking for pj-068 splitters but they don’t seem to exist. Can anyone advise on how to overcome this? Thanks!

I think the snag is the mics we use need an active pre-amp so just splitting them might not work. Have a look at this unit, powered by small batteries or a 12v outlet.

I'm sure other units are available from other suppliers.
