The EL-Skyport Universal Plus Set from Elinchrom is the latest evolution of EL-Skyport wireless radio triggers and receivers. 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. Transmitter channels 1, 3, 7, 9, 12, 15, 18, and 20 are only compatible with the ELC Pro HD flash head and the ELB 400 battery pack system, while the same channels accept signals from EL-Skyport transmitter Plus and EL-Skyport transmitter Plus HS. The 2.5mm sync socket extends the transmitter’s versatility to cameras without hot shoes or for hard-wired flash units. Both the EL-Skyport Transmitter and Receiver Plus run on easily sourced AA batteries.
