Dynon intercom for 4 place aircraft

[RV14_TD]

I’ve been using the Dynon intercom for a couple of years now and really like its simplicity and low panel foot print. As I’m presently building a 4 seater I was wondering if there is any hack or extension that would allow me to plug into the intercom 3 passenger headsets in place of the single one. There is this all thread covering the subject but it doesn’t provide an answer to my question. I don’t need a second COM, I don’t need entertainment inputs, no extras.
I would appreciate any help.

Maybe not, depending on what you want. You could use a mixer to allow additional headsets to hear the intercom, and possibly to talk on it, but it would get complicated. I would ask Vern Little that question. He designed the AMX-2A and AMX-10A mixers for aircraft.

Out of curiosity, have you considered the PM1000II from PS Engineering? It's designed for certified planes, but it has a similarly small footprint, and offers similar functions. It's about twice the price of the 2S, but it's four place instead of two, so....

Get a PS Engineering audio panel. An intercom is no substitute for a real audio panel.

I did have a look at the MGL audio panel. It has all the bells and whistles which I don't want and don't need. That's why I'm looking for a solution to adapt the Dynon intercom

The PM1000II doesn't have all the bells and whistles the MGL intercom has. It doesn't have stereo, Bluetooth or a cockpit voice recorder. Other than being four place instead of two, it's very similar in function and form to the Dynon intercom. That's why I asked if you'd looked at it. It's also cheaper than the MGL.

For listen only (backseat pax), just connect the pax headphone phone jacks in parallel with the copilot or pilot phone outputs from the intercom. Do not connect the pax mic jacks to anything. If you want to listen to the pax, things get more complicated, requiring a mixer and more circuitry. At some point, a 4-place intercom is the simplest solution.

Thanks!

Thank you!
