Operating Instructions
The XTALK Link Signal Boost offers multiple operating modes to suit various communication needs.
Link Mode: Unlimited Connections
In Link Mode, the XTALK Link Signal Boost removes the traditional user limit of the Xtalk system, allowing for an unlimited number of headset connections. This mode is ideal for large gatherings, complex events, or expansive outdoor environments where extensive team communication is required.

Master Mode: Up to 13 Connections with Group Scheduling
Master Mode allows the XTALK Link to function as a central hub for up to 13 Xtalk headsets. This mode supports flexible group scheduling, enabling precise communication management. You can create A/B group communications with various options, including two-group chat, single-group communication, and full-field mute.

Line In Mode
Line In Mode allows the XTALK Link to be wired through its Line In ports. This is particularly useful in complex environments where stable, wall-penetrating signals are crucial. In Line In Mode, the Link can only connect wirelessly to one master unit, providing a robust wired backbone for your communication system.

Seamless Compatibility
The XTALK Link Signal Boost is fully compatible with all SYNCO Xtalk headsets, including XPro and XMax models. In Link mode, it supports mixed-group pairing, offering flexibility to build a customized communication system tailored to specific needs and environments.
