Professional HD Live Production

The switcher supports a wide range of HD video formats, including 720p, 1080i, and 1080p up to 60 fps. Every SDI input includes a built-in standards converter and frame synchronizer. As a result, cameras using different video formats can be connected simultaneously without requiring external converters.

10 Standards-Converted 3G-SDI Inputs

The Blackmagic Design ATEM 1 M/E Constellation HD Live Production Switcher provides 10 independent 3G-SDI inputs with embedded audio support. Therefore, you can connect multiple broadcast cameras, PTZ cameras, media players, or graphics systems while maintaining excellent image quality.

Six Flexible 3G-SDI Outputs

The switcher includes 6 configurable 3G-SDI outputs that can function as:

• Program output
• Preview output
• AUX output
• Clean feed
• Multi-view output

Consequently, production teams can distribute video feeds to recorders, monitors, projectors, and streaming encoders simultaneously.

Professional broadcast tools include:

• 1 Mix Effect (1 M/E)
• 4 Advanced Chroma Keyers
• 1 Digital Video Effects (DVE) processor
• 2 Media Players
• 16-way MultiView
• SuperSource support
• Transitions and wipes

These features allow producers to create polished live broadcasts with professional graphics and visual effects.

Built-In Fairlight Audio Mixer

The integrated Fairlight audio mixer offers professional audio control with multiple channels of embedded SDI audio. In addition, each input supports advanced processing such as:

• 6-band parametric EQ
• Compressor
• Limiter
• Noise Gate
• Expander
• Audio Follow Video (AFV)

As a result, your live productions maintain clear and balanced sound without requiring a separate audio processor.

USB Webcam Output

A built-in USB-C webcam output allows the switcher to appear as a standard webcam on Windows and macOS computers. Therefore, it integrates easily with platforms such as Zoom, Microsoft Teams, Skype, and OBS Studio without additional capture hardware.

Ethernet Control and Software Integration

The switcher supports Gigabit Ethernet for remote operation using the included ATEM Software Control application. Furthermore, it is compatible with optional ATEM Advanced Panels, enabling professional hardware control for larger productions.

Compact Rack-Mount Design

Despite its extensive capabilities, the ATEM 1 M/E Constellation HD occupies only 2/3 of a rack width and 1 rack unit in height. Consequently, it is suitable for OB vans, production studios, fly packs, and mobile live streaming systems where space is limited.
