In addition to manual power control and power distribution control for different groups and channels, the X1R-N offers high-speed synchronization up to 1|8000s. In mix mode, multiple flash units can be operated simultaneously in both i-TTL and manual modes. With the i-TTL passthrough mode, the TTL signal can be looped through to a flash on the transmitter on the camera. The X1R-N supports 32 channels in five groups. The camera menu allows you to control the flash performance of compatible devices. This allows you to change the flash setting quite easily without running back and forth. High-speed sync lets you control the shutter speed from 1|250s to 1|8000s beyond the normal shutter speed. Take great photos in bright sunlight, capture darn fast movements or almost completely block out daylight. This function is also possible on studio flashes, to operate the X1R-N on a studio flash or Porty, PC sync cable is already included. All modes like i-TTL, manual and also multi or stroboscope flash are supported. You can synchronize the release to either the first or second shutter curtain.
