The HKB-2X is a four-channel, two display with shift page, digital partyline speaker
station that connects with the HMS-4X Main Station and other user stations using
various cable types, including a single shielded twisted-pair cable.
The HKB-2X speaker station can assign and monitor four channels of intercom over a
single cable while communicating (talking) on any two of the four channels at any given
time. Access to channels and other functions are assignable through the main menu or
the Core Configuration Manager (CCM)*. User controls include position adjustable OLED
displays, momentary/latching Talk button, Call button and rotary encoder level controls.
The station has separate screw-pot level control for program audio.

When using a combination of power options, the priority of power is applied; local
power first, PoE second, then Powerline. The HKB-2X receives audio data, control
data, and DC power via the same Powerline cable connection to a HMS-4X Main
Mounting Options
The HKB-2X can be mounted into a standard 4-gang ANSI/NEMA OS-1 electrical box
or in the optional S-Mount enclosure to enable desktop use. Screw holes on the front
panel are provided to accommodate surface wall box mounting
