Clear-Com HXII-KB HelixNet 4-Channel Digital Speaker Station

The HXII-KB is the HelixNet speaker station for a fixed operating position. Four channels are laid out across two displays with a shift page key, so an operator can reach more assignments than the keyset count suggests without hunting through menus. It accepts a headset or a 3-pin Tuchel gooseneck microphone and carries its own loudspeaker amplifier for open-air listening when a headset is off.

Audio and control arrive over a 5-pole terminal block Powerline connection or RJ45 Ethernet with PoE. The loudspeaker amp drives 8 ohms to +18dBu before clipping with response from 200Hz to 10kHz, and the headphone amp delivers +12dBu into 32 ohms or more. The -X7 build adds a 7-pin XLR headset connector with two PTT logic inputs that can be assigned to talk, call, mic or headset keys.
