NEEWER 16-Channel RT-16 Wireless Flash Trigger

The Neewer RT-16 is a 16-channel wireless flash trigger system that fires compatible studio strobes from up to 30 meters for synchronous, high-speed sync at 1/200s.

Designed for studio and on-location photographers who need reliable remote flash firing, the RT-16 pair (transmitter and receiver) offers simple setup, low power use, and channel selection to prevent cross-talk. It uses a 433MHz radio link and ships with a PC sync cable and adapters so you can connect to a wide range of studio lights and cameras.

How do I set it up with my camera and studio light?

Getting started is straightforward: match the channel selection on both units, plug the receiver into your strobe’s sync jack, and mount the transmitter on your camera hot shoe or connect via PC sync cable. A test button confirms the link before you start a shoot.

• Set transmitter and receiver to the same one of 16 channels
• Insert receiver plug into flash sync port (3.5mm) or use included adapter
• Attach transmitter to camera hot shoe or use a PC sync cord if needed
• Press test on transmitter; verify flash fires

What compatibility and connections does the RT-16 support?

The receiver provides a 3.5mm trigger output and includes a 3.5mm-to-6.35mm adapter, so it works with Neewer S101 series strobes and many other studio lights with standard sync inputs. Cameras with hot shoes work directly; cameras without can use the supplied PC sync lead.

• 3.5mm receiver output with 6.35mm adapter included
• Works with Neewer S101-300W/400W and many other studio lights
• Camera hot shoe or PC sync cord options covered
• Standard 433MHz radio works in most shooting environments

What are the range, speed, and power characteristics?

This trigger pair operates at 433MHz with a maximum open-air range around 30 meters and supports high-speed synchronous firing up to 1/200 second. The transmitter uses a 12V 23A battery; the receiver runs on two AAA cells for economical long-term use.

• Radio frequency: 433MHz; open-area range ~30m
• Sync speed: up to 1/200 second for crisp timing
• Transmitter battery: 12V 23A (included)
• Receiver batteries: 2 × AAA for long service life

How does the RT-16 avoid interference during busy shoots?

With 16 selectable channels, you can isolate groups of flashes or avoid neighboring systems on set. The receiver includes an LED trigger indicator and a dedicated on/off switch so you can control each unit individually and confirm connectivity at a glance.

• 16 selectable channels to reduce cross-triggering
• Receiver LED shows triggering status in real time
• On/off switch on the receiver to conserve power between takes
• Channel selector is accessible on both transmitter and receiver for quick changes

Who is this for: The Neewer RT-16 is aimed at portrait, product, and small-studio photographers who need an affordable, no-fuss wireless trigger to synchronize off-camera strobes. It's also a good match for educators and hobbyists assembling lighting kits, and for professionals who require extra channels to separate lighting groups during multi-photographer shoots. Avoid using it as a substitute for specialized TTL or high-speed sync systems if you need camera-controlled flash exposure; instead, use it where robust manual triggering and simple compatibility matter most.
