Racal Acoustics RA108 headset

Snagged one off ebay a few weeks back, seems like a good headset, and fits under my helmet perfectly.

Bad thing is, its the Canadian version for the IRIS/MeshNET system, so the plug is different. Am I hosed on this, or is there an adapter I can get to make this work with a VIC-1/3?

It's not that easy as swapping a plug....

that's what I was afraid of.... any idea where I can look into making it work? or am I just hosed?

www.swatheadsets.com Give them a call. but it wont be cheap I bet.

called them, they were no help.


Waiting on a call from Racal, but got some replies from Gen. Dynamics Canada and got a pin-out for their typical style headset. Found the female plug blank from Nexus, so as soon as I can verify the pinout from Racal, I might be in business. The headset I have is active noise reduction and stereo, so at worst I may have to wire an adapter for mono and lose the ANR all together.


You wouldn't have a pinout for the VIC-1 headset plug would you?

Check this link. Has pinouts for U-229 connector.

so if I read this correctly, there's a common ground for both the mic and the headset together? And the E pin for intercom use is a positive battery lead?

Did you call the CA #, or the NY #?

I got one it wont work with the vic-1 system properly I am told only one ear phone will work. I was told by a guy in the Canadian military that they were warned not to hook them up to a vic-1 system as it will fry the AM-1780 box because it has a powered or amplified mic. and it draws the power from the 1780 and the 1780 is not designed to out put power for that function for a vic-3 head set. but it will work with the VIC-3 system just fine. I have been too chicken to hook it up to my unit to see if it will fry it. Let us know what you find out I would like to get mine working also.

Well damn that just stopped the thread completely. hmmm

Im guessing an H-161F/GR wont work with the system either?

so can anyone verify if the mic on these are amplied/powered? I'd like to use these under a kevlar if I can

You probably have to convert the connector to a vic-3 style connector. You will need a vic-3 style male and female connector as you need to change the connector on the 2298 box also. You need to provide 24 volt to the middle terminal on the connector at the 2298. There is a place to pull it from inside the 2298. I am not sure how the Canadian one works so your proceed at your own risk. When I get around to it I am going to convert a 2298 box for my bose headset.
