The SMDV Free-7S Professional Radio Slave Kit is a complete wireless flash triggering system designed for professional photography applications. This comprehensive set enables remote activation of 220-volt flash heads from distances up to 30 meters outdoors, providing photographers with enhanced creative lighting flexibility. Operating on the 2.4 GHz frequency band with sixteen standard channels and six separate groups, the system ensures reliable performance in busy environments or when working with multiple lighting setups simultaneously.
The kit consists of two primary components: a transmitter that mounts to your camera's hot shoe using the center contact pin, and a receiver that connects directly to the flash head's power supply. The transmitter operates on a single AA battery, while the receiver functions with 100-240V AC power, making it compatible with international voltage standards.
Key technical specifications include a sync speed capability of up to 1/250 second, omnidirectional signal transmission that allows placement of flash heads even behind walls or obstacles, and individual brightness control for each flash head within the system. The channel selection system helps avoid interference from other radio devices in the vicinity, enabling multiple photographers to work simultaneously in the same studio environment without signal conflicts.
Installation is straightforward, requiring connection of the receiver to the flash head using the included short AC cable, followed by reconnection of the main power cord to the receiver unit. The system's robust construction and reliable performance make it suitable for studio photography, location shoots, and other professional applications where precise lighting control and wireless operation are essential. The black finish provides a professional appearance that matches standard photographic equipment aesthetics.
