Since I was planning to use Bose headsets in the RV-10 , I had already decided that I would NOT install the standard RCA earphone/mic audio jacks.  Instead I plan to ONLY install the Bose (LEMO) jacks with provision for earphone/mic audio and power for ANR.  That decision is even more reinforced now that Lightspeed is now offering their Zulu headset with the LEMO connector.  If I ever have to use a standard headset, I carry a RCA earphone/mic audio jack to LEMO adapter.



The only thing I cannot determine is if the Lightspeed LEMO is the same as the BOSE LEMO.  I can't find any details on the Lightspeed LEMO and I found one reference that states it is a 5 Pin LEMO where I know the Bose LEMO is a 6 pin.  It would be a shame if Lightspeed used a different form factor than the 6 pin LEMO that is used by Bose.

Call Lightspeed and ask.  I've found them to be extremely responsive and more than willing to chat when I've called.

William,



I have both in mine, standard RCA and the Bose panel powered LEMO but I would love to take my Bose to other aircraft, do you know of an adapter that will go on the LEMO to RCA jacks? At OSH last year they said nothing excpet they would sell me a new cord for the headset for $135 but it would be easy for me to swap out..something I'd rather not do. I do plan another Bose for the RV-10...just I have two other perfectly good ANR headsets for passengers that don't have their own.

Is Zulu available in an aircraft powered version to eliminate the need for

AA batteries?



Yes.  The Zulu: P is the aircraft powered version.  It uses the most common

aircraft powered ANR headset plug, the 6-pin LEMO.  This plug is standard on

all Cirrus and Cessna 350, and 400 series aircraft.  Should you need it, the

mating half of the connector is available from many pilot supply retail

stores.



It still doesn't answer your question, but it does appear like there may be

some hope that they are compatible

I wired all 4 locations for both Bose and standard jacks.

I know, that doesn't answer the Lightspeed vs. Bose

question.  I have had a couple people ride along that

preferred to use their own, which is understandable.  I

also have a spare standard cord I can use if I need.



I installed a 5th headset jack for the rear seat that

often gets used to feed audio into a video camera.

That comes in handy sometimes.

You may also want to compare it to the David Clark ones as well.  I have the Flightcom ANR Panel Power Headset and then use a 10 pin connector which is a pain because they are the one one I know of that use this connector.  I too am thinking of mabe the Bose or Lightspeed and I also have the normal jack in case someone want to use there own headset without adapters.

I would reinforce the decision to also put in the RCA jacks as a back up.

Kinda like a backup set of steam guages......

Well I guess like all things "it depends!" To use your analogy, If you are a VFR pilot and only fly VFR, the need for steam gauge backup is kind of redundant as looking out the window should be your backup.  Same thing with jacks, are you worried about the jacks failing or that you may bring the wrong headsets?



All the same signals are in the LEMO jacks, only in a different form factor.  I'm looking at a source for the male LEMO jacks and will make a few female RCA to male LEMO adapters.  Should be able to put these together for a LOT less than the $100-$135 that Bose is asking--stay tuned.  But then thier adapter includes a battery case for power.  If you just want to get RCA signal to LEMO signal, its just wires.

William I think that's the kicker, you need a power supply if your using the headset on standard RCA jacks. It is soooo nice just plugging in the panel powered Bose headsets with that LEMO jack.

I installed the Bose (Lemo) connectors and fell into a trap with all the black wires. From memory:  there are four or more pairs emitting from the connector and each pair has a black wire. These are not common. You must use a meter and identify each wire.

Just to clarify,  since I will only have the LEMO jacks, I would only need the RCA (female) to LEMO (male) adapter if I wanted to use a headset with regular RCA plugs-this requires no power.



If I want to use the Bose headsets with LEMO jacks in another aircraft without LEMO jacks, there are two options;

 1) You can easily make an adapter by purchasing the $30 installation kit from spruce, adding RCA plugs and wire the power leads into a cigarette lighter adapter or battery pack.

 2) You can purchase the Bose LEMO to RCA adapter with battery pack for about $100-$135.



Installing only the LIMO jacks actually simplifies wiring.  I've seen folks totally mess up their intercom wiring and introduce ground loops when tying the RCA jacks to the LEMO in the panel.
