The Clear-Com HXII-KB-X4 is a flush-mount HelixNet speaker station built for professional wired intercom systems where operators need convenient access to multiple communication channels without occupying a traditional rack or desktop position. Its four-gang wall-mount design makes it particularly useful for theaters, broadcast facilities, production rooms, control areas, and live event venues where reliable communication needs to be available at a fixed location.
The HXII-KB-X4 combines a built-in loudspeaker with headset connectivity, programmable keysets, OLED displays, and backlit controls. Operators can communicate hands-free through the station's speaker and microphone or connect a compatible intercom headset when greater privacy or isolation is required.
As part of the Clear-Com HelixNet system, the HXII-KB-X4 can be connected through Ethernet or Powerline, depending on the system architecture. It can be deployed with Clear-Com Arcadia Central Station or an HMS-4X HelixNet Main Station, providing a scalable solution for installations that require multiple user stations throughout a facility.
Flexible HelixNet Communication Control
The HXII-KB-X4 provides two programmable keysets that can be assigned to HelixNet communication channels. Shift functionality allows operators to access additional channel assignments, providing convenient control when several intercom channels need to be available from one location.
The station's OLED displays provide clear channel and status information, while the illuminated keys make it easier to identify active functions in dim production environments.
Depending on the installation, the station can be configured for headset or hands-free operation, making it suitable for both dedicated communication positions and locations where users need to communicate without wearing a headset.
Designed for Permanent Installations
Unlike portable intercom beltpacks, the HXII-KB-X4 is designed to become part of the facility's infrastructure. Its four-gang flush-mount format provides a clean installation in walls and other fixed locations.
An optional desktop enclosure can also be used when a portable or tabletop configuration is preferred.
The station supports Ethernet connectivity and Powerline communication, while Power over Ethernet (PoE) provides an additional power option when supported by the system configuration.

When used with an HMS-4X, the system can support up to 64 endpoints, with the available channel capacity expandable from 12 to 24 channels with the appropriate licensing.
Actual system capacity depends on the host equipment, licensing, network configuration, and HelixNet system architecture.
