Atomos UltraSync Blue Wireless Timecode Sync
The Atomos UltraSync Blue synchronizes timecode over Bluetooth to any camera, audio recorder, or app that supports the timecode-over-Bluetooth protocol, cutting cable runs out of a sync workflow that used to require a wired LTC box on every device. It provides frame-accurate timecode to up to six compatible Bluetooth devices simultaneously from up to 32.8 feet away, and it auto-detects and pairs with supported gear rather than requiring a manual setup pass on each unit.
When a shoot needs more range than Bluetooth alone covers, the BLUE also syncs over RF, pairing with other UltraSync BLUE units or Atomos AtomX SYNC modules across a long-range link of up to 656 feet. A built-in 800mAh battery runs the unit for roughly 20 hours and recharges over USB-C, and once paired, timecode embeds directly into the recorded media so it's already there when the footage lands in an editor's timeline.
