Atomos UltraSync ONE Wireless Timecode and Sync Generator (US/Canada)
The Atomos UltraSync ONE is a wireless timecode, genlock, and word clock generator that keeps cameras and sound recorders in sync over the Atomos AirGlu RF network. Set it up as a transmitter that serves timecode to the set, or as a receiver that follows one.
This US/Canada version uses the radio frequencies for the United States and Canada.
Timecode and Sync
As a transmitter, the UltraSync ONE generates its own timecode or follows an external source, such as house timecode or a broadcast truck’s timecode. Its LTC port sends or receives timecode, and its SYNC port outputs genlock to a camera, word clock to a sound mixer or recorder, or a second LTC feed. It gives timecode to any device with an LTC input. For a device without one, it sends mic-level audio timecode that the device records on a spare audio track.
Running free, its internal clock holds to 0.5 ppm, about one frame of drift in 24 hours. Locked to a master over RF, it holds to 0 ppm. It runs at 23.976, 24, 25, 29.97, 29.97 drop frame, 30, and 30 drop frame.
AirGlu Wireless Network
The UltraSync ONE syncs over a sub-GHz RF network with a range of up to 200 m (656 ft) in line of sight. A receiver that moves out of range free-runs until it is back in range of the transmitter. The link runs both ways, so a Ninja TX, a Ninja fitted with Atomos Connect, or a Shogun in timecode server mode can monitor and control other AirGlu devices on the network.
Several UltraSync ONE units sync with each other or join a wider network with other Atomos AirGlu products. These include the UltraSync BLUE, Ninja TX, Ninja V and V+, Ninja and Ninja Ultra with Atomos Connect, Shogun, Shogun Ultra, and Shogun Connect.
Power and Build
A built-in rechargeable 800 mAh lithium battery lasts a full shooting day on a single charge with RF, genlock, and the OLED display all running, and recharges in 3 hours. The USB-C port charges the battery, powers the unit continuously at 5 V, and takes firmware updates. The UltraSync ONE draws less than 1 W.
The body is ABS polycarbonate and passively cooled. It measures 55 × 44 × 17 mm (2.17 × 1.73 × 0.67 in) and weighs 39 g (1.38 oz). The Up, Down, and Select buttons run the menus on a 128 × 32 OLED display, and the diversity antennas are built inside the case. The back has a dedicated area for a hook-and-loop mounting strip.
Good to Know
Atomos makes optional cables from the UltraSync ONE to XLR, 5-pin LEMO, and right-angle 3.5 mm connectors. They also make silicone cases, one of them with 1/4-inch mounting threads.
