LSAR19 is a 1U, 19-inch rack chassis designed to accommodate up to four LS-Core or LS-Node devices. This accessory enables compact LS deployments, for example a 16-universe node configuration using four LS-Node4 units, or a setup with one LS-Core plus LS-Node2 and LS-Node4 to provide eight direct DMX ports. It is intended for tidy, rack‑mount installation of Lightshark LS systems in theatre, broadcast, or install environments.
