Can I mix old and new beltpacks with new and old headsets?
Mostly. Most full-size headsets with a four-pin female XLR type connector will work with Clear-Com, Telex, HME and Anchor stations, both wired and wireless, that have a matching connector. Some stations that have been used with lightweight headsets that have electret mics may need a minor modification for proper operation. Some new lightweight headsets may require mic power which limits the selection of beltpacks that can support them.
