Clear-com HKB-2X Flush mount Speaker Station
Clear-com HelixNet HKB-2X speaker station is a
4-gang flush-mountable user station with four channels over two shift pages
hosted by the Arcadia® Central Station or HelixNet HMS-4X main station.
User Station
This innovative front panel user station provides
two keysets assignable to any intercom channel to each of the two pages,
which the user can toggle between for a total of four channels. The
station’s displays can be swiveled for optimal viewing angle. The user
station is provided with a headset connection, gooseneck mic connector,
loudspeaker and Program Audio level controls.
HKB-2X can be mounted
in a standard 4-gang electrical enclosure or the optional S-MOUNT
multipurpose enclosure for portable and desktop applications. The HKB-2X-X7
has seven-pin headset connection with additional PTT GPI, assignable to user
station keys.

HelixNet System Hosts
Arcadia: Supports up to 64
HelixNet endpoints (HRM-4X, HKB-2X & HXII-BP) over Ethernet. Up to 24
Channels can be HelixNet Enabled using a Licensed Port for assignment to
any HelixNet endpoints keyset.
HMS-4X: Supports
up to 64 endpoints (HRM-4X, HKB-2X, HBP-2X, HXII-BP, HLI-2W2, HLI-4W2,
LQ port). User stations can connect via HMS’s 2 Powerlines (see
datasheet for limits) or over Ethernet via optional HLI-ET2 module. HMS
allows use of 12 channels which can be expanded to 24 using optional
license.
