Sidus Link Pro - Sidus One vs. Sidus Four
Side-by-side comparison of Aputure's two wireless DMX transmitters. Use Sidus One for portable single-universe shoots, use Sidus Four for multi-universe rigs.
Overview
Sidus One and Sidus Four are Aputure's two wireless DMX transmitters for Sidus Link Pro. Both let your iPad control DMX and CRMX rigs wirelessly. The difference comes down to universe count, form factor and console integration.

You run on USB-C power - V-mount with USB-C, AC adapter or a power bank.

Pick Sidus Four If
