BOSE A20 & THE EC135
Hi All,
Does anybody know for certain if the EC135 intercom system is LOW or HIGH impendence? We are looking to pruchase some Bose A20 headsets for the machines.
I have a A20 that I used in the EC225 and it does not work in the EC135. I seem to remember that the EC225 was LOW impendence and therefore am assuming the the EC135 is HIGH.
I would appreciate anyone's experience of this issue.
