## Summary description

## Long description

The Ulanzi flash trigger 2.4 GHz TX/RX USB-C for studio flash Ulanzi LA10 (model SB11572) is a wireless triggering solution designed to synchronise cameras with studio monolights. Operating on a 2.4 GHz link in transmitter and receiver configuration, it enables remote triggering of compatible studio flashes such as the Ulanzi LA10 and supports USB‑C connectivity for power and fast communication. The device is intended to simplify off‑camera flash setups and provide reliable sync for portrait, product and studio photography.
Advantages
The trigger uses a 2.4 GHz radio channel for stable wireless communication and reduced interference compared with basic infrared systems. With distinct TX (transmitter) and RX (receiver) roles it supports multi‑light setups where one camera‑mounted transmitter fires multiple receivers connected to studio monolights. USB‑C connectivity provides a modern and reversible power/data port, and the compact form factor makes the units simple to position on light stands or camera hot shoes. The design emphasises straightforward compatibility with studio monolights that accept external trigger inputs.
Suitable for
 Portrait photography with one or several off‑camera monolights
 Studio product photography requiring synchronized flash firing
 Controlled lighting setups for small to medium studio environments
 Photographers who need a compact wireless sync solution with USB‑C power
When it may not be suitable
This trigger is intended for use with studio monolights that accept external trigger signals; it may not support TTL or HSS functions if those features are not implemented in the studio flash or the trigger firmware. If full camera-to-light automatic exposure control is required, confirm compatibility with the camera and flash systems before purchase. Very long‑range outdoor applications or environments with extreme RF congestion may reduce effective range or reliability.
Key specifications
 Operating frequency: 2.4 GHz wireless link
 Configuration: transmitter (TX) and receiver (RX) roles
 Connectivity: USB‑C port for power and communication
 Mounting: camera hot shoe compatible transmitter and receiver mounting options for light stands
 Designed use: remote triggering of studio monolights and off‑camera flash units
How to use
Attach the transmitter to the camera hot shoe and mount the receiver to the studio flash or place it on a light stand and connect to the flash trigger input. Power the units using a USB‑C cable and ensure both units are set to the same channel or group. Test fire at short range to verify sync and then adjust flash power and positioning as required for exposure and light shaping. For multi‑light setups, assign each receiver as needed and confirm simultaneous firing from the single transmitter.
What to consider before purchase
 Verify your studio flash accepts an external trigger input compatible with the receiver.
 Confirm whether TTL or high‑speed sync (HSS) is required and whether your flash supports these when used with external triggers.
 Check expected working range and possible RF interference in your shooting environment.
 Ensure you have USB‑C cables or power sources for the transmitter and receiver if not included.
Usage recommendations
Use the Ulanzi 2.4 GHz TX/RX trigger as a reliable manual sync for studio sessions where consistent, repeatable flash firing is required. Position receivers close to the flashes when possible and verify channels/groups before shooting. For critical work, perform test exposures and keep spare power sources and cables available to avoid interruptions.
