The Clear-Com HXII-BP is a full-duplex 2-channel digital partyline beltpack that can carry power and audio over a Power-over-Ethernet (PoE) or single XLR cable. The user can listen via a headset and can talk via a headset mic. The HXII-BP's menu screen allows users to independently select among and change channel assignments as necessary, from any position on the intercom line. The brightness level of the OLED screen, Talk and Call buttons can be controlled from the beltpack. The OLED screen can show the level adjustment and then will revert back to the standard 2-channel screen. Every HelixNet device may be assigned a role, which is a pre-defined configuration of that particular device. Multiple channels can be assigned to a key, allowing one key to address many channels with a single push of a button. Made from light-weight poly-carbonate, the HXII-BP is built to withstand rugged environments. The sturdy beltclips on the back of the HXII-BP can be used to be worn on a belt or they can be used as feet for desktop use.
