ARRI ALEXA EXT Distribution Box EDB-1 – K2.72038.0

The ARRI ALEXA EXT Distribution Box EDB-1 (K2.72038.0) is a compact, professional-grade accessory designed to expand the connectivity options of the EXT port on ARRI ALEXA cameras. By providing three additional EXT sockets, it enables simultaneous use of multiple accessories and sync solutions, making it essential for complex multi-device workflows.

Equipped with a built-in short cable for direct connection to the camera’s EXT port, the EDB-1 is engineered for seamless integration with the ALEXA system. Whether you’re working in 3D production, multi-camera synchronization, or advanced motor control, the EDB-1 ensures reliable connectivity without compromising performance.

Why This Box is Essential

The ALEXA EXT Distribution Box EDB-1 addresses a key limitation of single EXT ports on cameras. Instead of choosing between devices, cinematographers can now run 3D Sync and UMC-3/UMC-4 motor controllers simultaneously. Its robust ARRI-certified build guarantees professional reliability on demanding film sets.

Compared to improvised splitters or third-party solutions, the EDB-1 ensures precise timing and flawless signal integrity, protecting both workflow efficiency and image quality.
