Partyline: Can my 2 channel Beltpack allow me to talk and listen to both channels at the same time?

The simple answer is "Yes" Unlike some 2 channel  belt packs offered by others, the Clear-Com dual channel packs -- such as the RS-502 and RS-602 allow the user to talk and listen to both A&B at the same time.  This is a feature you can use or "lock out" as in the case of the 602. In some production needs, you may need to speak and listen to "A" but still need to hear "B"   All this is possible with 2 channel packs from Clear-Com...
