The Spectrum Studio is eMotimo’s first motion control head purpose-built for broadcast. Featuring a built-in network adapter and powered I/O port, it delivers native IP control and seamless integration with our latest beltless dolly kits - scalable to virtually any track length. Built on the proven and reliable Spectrum ST4.3 platform, it supports precise control of pan, tilt, slide, focus, iris, and zoom for camera payloads up to 15 lbs. Operate locally with the included gaming controller for smooth feathered live motion, presets, and looping moves, or take control from the booth using Bitfocus Companion/Stream Deck, Skaarhoj PTZ surfaces, and upcoming eMotimo control options.
