The Broadcast Box
Motor Control Excellence for Cine Lenses in Broadcast Workflows
The Chrosziel Broadcast Box bridges the gap between cinematic visuals and broadcast precision. Designed as a versatile, all-in-one motor control system, it allows full remote control of manual cine-style lenses. Its integrated 3-channel motor controller, quick-release baseplate, and robust power management make it ideal for live production environments, remote heads, or Steadicam rigs. Whether in multi-cam studio settings or complex robotic setups – the Broadcast Box brings professional-grade control to every shoot.
- Seamless Integration into Broadcast Workflows: Equipped with dual 20-pin Hirose interfaces for analog/digital Focus & Zoom demands, LANC input, and full wireless control via Chrosziel’s Magnum hand unit.
- High-Performance Motor Control with Auto Calibration: Three independent motor channels for FIZ (Focus, Iris, Zoom) control, compatible with industry-standard motors (Chrosziel, Preston, Hedén, etc.) and intelligent auto-calibration of lens end stops.
- Universal Camera Mounting with Height Adjustability: Quick-release bridge plate with two-stage height settings and 15mm rod support – compatible with a wide range of cameras and rigs.
- Robust Power Management and Future-Proof Connectivity: The built-in power management delivers consistent motor torque regardless of input voltage, while USB-C Power Delivery (up to 20 V), CAN Bus output, and firmware updates via USB-C ensure reliable operation and easy field upgrades.
