The SYNCO Xtalk Master XM4 is a next‑generation wireless intercom system designed for professional teams that demand instant deployment, absolute reliability, and precise real‑time communication. Built on SYNCO’s advanced Mesh Talk MasterFree 3.0 architecture, the XM4 eliminates the traditional master unit entirely. Every headset functions as an equal, intelligent node, automatically forming a self‑organizing and self‑healing mesh network the moment it is powered on. As users move, disconnect, or rejoin, the system adapts instantly, maintaining seamless communication without manual pairing or setup.
The XM4 kit provides a powerful four‑headset core that supports up to eight local users simultaneously, delivering natural full‑duplex communication with ultra‑low latency of approximately 45 milliseconds and a stable working range of up to 500 meters. Intelligent adaptive routing ensures timing accuracy and consistent performance, even in demanding multi‑user environments. This makes the system ideal for film productions, live events, sports, stage direction, broadcast, and complex operational workflows where every instruction must be heard clearly and on time.
To maintain reliability in challenging RF conditions, Xtalk Master features a dual‑band, dual‑antenna design that operates across two independent frequency bands. When interference affects one band, the system automatically switches to the other, ensuring uninterrupted communication where conventional single‑band systems often fail. Audio clarity is further enhanced by ENC 2.0 AI‑powered noise cancellation, capable of significantly reducing wind, crowd, and mechanical noise while emphasizing speech for clear communication in noisy environments.
For professional production workflows, the Xtalk Master XM4 includes a dedicated 3.5 mm monitoring input, allowing users to listen directly to camera or recorder audio without leaving the intercom network. System control and scalability are handled through the SYNCO Audio App, which enables group creation, private one‑to‑one communication, real‑time device and battery monitoring, locating misplaced units, and over‑the‑air firmware updates. Smart A/B grouping and priority PTT mode allow teams to communicate efficiently, ensuring critical messages cut through instantly when timing is essential.
Designed for extended use, the lightweight and ergonomic headset construction minimizes fatigue during long working days. A replaceable 1050 mAh battery provides up to 15 hours of continuous operation, keeping teams powered throughout full‑day shoots or events. When larger operations demand more capacity, the Xtalk Master system supports expansion through base stations, enabling large‑scale team communication and integration with other professional intercom systems.
