About the course

Automated Voice-Tracking Solution

Bring simple, automated camera switching to podcasts, panel discussions, classrooms, visual radio, talk shows, and creator studios with the VoiceTRX50.

VoiceTRX50 reacts instantly to audio activity from USB mixers, enabling a fully automated multi-camera workflow for creators, educators, and broadcasters. Automatic switching follows the active speaker, delivering clean, natural transitions. With CG subtitle support through Datavideo switchers, it ensures a clear and engaging viewer experience in-room, online, or on-demand.

Designed for simplicity and affordability, VoiceTRX50 integrates seamlessly with a wide range of USB audio mixers—from compact interfaces to multichannel models. Its broad compatibility makes it ideal for creator workspaces, podcast studios, classrooms, panel discussions, and small to medium meeting rooms.

 

Integrate with Your Existing Audio Mixer?

Want to keep your current audio mixer, but it doesn’t support USB multi-track output? No problem.

VoiceTRX50 works seamlessly with your existing setup using affordable USB audio interfaces. Simply connect the interface to your mixer’s auxiliary output, plug it into the VoiceTRX50, and you’re ready to automate voice-activated switching—without replacing any equipment.

Hands-Free Multi-Camera Production

VoiceTRX50 eliminates the need for a production operator.

The system automatically follows the active speaker using audio signals from USB mixers, delivering clean, broadcast-style switching without showing camera movement. When paired with Datavideo switchers, it also supports CG subtitles for real-time speaker identification.

What you will learn

By the end of this course, you'll be a pro at running the Datavideo Voice tracks 50 automated system. You’re going to walk away knowing exactly how to hook up switchers, PTZ cameras, and USB mixers so they all talk to each other over a network. More importantly, you’ll master the "brain" of the system—learning how to map audio tracks to camera presets and using clever tweaks like trigger delays to make the automated cuts feel smooth and natural, just like a real person is sitting in the director's chair.

Background knowledge, skills and tools needed for this course

Before you jump in, you should already be comfortable with the basics of gear—think knowing your way around SDI/HDMI cables and XLR mics. Since the whole setup runs on a network, you’ll need to know how to set a static IP and understand what a CIDR mask is. It also helps a ton if you’ve played around with PTZ cameras before and know how to save a preset. Having the actual hardware, like the Voice tracks 50 and a RODECaster Pro 2, on hand will definitely help the lessons stick.

Who is suitable for this course

This course is a perfect fit for anyone managing a school TV studio or a corporate training setup where you need high-quality, multi-cam video but don’t have a full crew to run it. It’s also a game-changer for solo streamers or Podcasters who want to level up their show with professional, automatic camera switching. Whether you're a system integrator building studios for clients or a traditional director looking to see how AI can handle the heavy lifting, this course will get you up to speed on the future of "hands-free" production.
