The Elinchrom EL-Skyport Transmitter Plus provides photographers with an extra range for triggering and remote power control on all actual Elinchrom units from up to 200 m (656 feet) away. The EL-Skyport Transmitter Plus is designed with a swivel function that enables rotation to optimize reception. Its strong and robust mechanics makes it more durable than ever. In addition, the EL-Skyport Transmitter Plus works with AA batteries, available everywhere.
Sixteen channels are available 8 in Normal and 8 in Speed mode, with 4 discrete groups for different or sequentially triggered lighting setups at distances up to 656'. Channels 1, 3, and 7 are compatible with all enabled EL-Skyport units, while channels 1, 3, 7, 9, 12, 15, 18, and 20 are compatible with the ELC Pro HD flash head and the ELB 400 battery pack system. A 2.5mm sync socket extends the transmitter's versatility to cameras without hot shoes or for hard-wired flash units.
