Hey aa777888,
Thanks for your reply. I think it's bonkers that Lightspeed have hobbled themselves in this way with the Tango: Why not make it as adaptable as possible? Surely this would lead to more sales by offering the same adaptability as the competitors?
Anyway, I see that you mention the passive attenuation if the DC headset. Does DC supply any passive figures for their headsets? When I asked Lightspeed they said that '... We do not have publicly posted passive ratings on our headsets....'. I'm guessing that they do then have in-house test results and that they are not particularly encouraging.The S92 is a very noisey beast. It's something like 80db with just the battery on and all the rack fans spinning. It rises to around 90db in the 70% cruise...and if you put the cockpit heater on over 100db!
