Enttec Open DMX USB 70303 – Entry-Level DMX Lighting Interface for Beginners

The Enttec Open DMX USB 70303 is a reliable and budget-friendly interface designed for those getting started with DMX lighting control. Whether you’re a student, a hobbyist, or working on a small-scale production, this compact unit offers everything you need to control your first DMX lighting setup without breaking the bank.

Easy Setup and Simple USB Connectivity

Connecting is easy—just plug the Enttec Open DMX USB into your computer using the included USB 2.0 Type B cable. Once connected, it appears as a virtual COM port or USB serial device, depending on your installed FTDI driver. From there, you can start using a wide variety of compatible third-party DMX software.

512 Channels of DMX Output in a Compact Design

Despite its size, this small-but-mighty device can output a full universe of DMX512 (512 channels) through its female 5-pin XLR output. While it doesn’t include features like opto-isolation or a microprocessor, it’s a fantastic, affordable way to learn DMX or test lighting gear.

If you’re working on professional-grade shows or need features like frame buffering or EMU compatibility, ENTTEC recommends the DMX USB Pro or DMX USB Pro Mk2 instead.
