Questions for anyone familiar with Schmid and Frequentis voice switches.
1. Can these systems accept any type and impedance of microphone without adjustment ? Or are they built to function with just one type ?
2. What is the pin-out for the 8-pole Lemo headset connectors ? Is there more than one ? I would expect one pair for the microphone, one pair each for the earphones and the last pair for the PTT switch.
Be assured my questions are nothing to be alarmed about. I have a genuine technical interest in ATC equipment, as well as the industry as a whole.
Thankyou.
