Overview
The Blackmagic Design ATEM 4 M/E Constellation IP Plus Switcher is a high-capacity 3 RU live production switcher designed for broadcasters, studios, OB environments, venues, and event teams working in SMPTE 2110 IP infrastructures. Built for demanding multicamera productions up to UHD 4K60, it provides 64 native IP video inputs and 52 outputs, including multiview, across redundant 100G fiber Ethernet connections. This makes it a powerful central switching platform for larger IP-based facilities that need substantial channel density, flexible routing, and dependable redundancy.
As part of the Constellation family, this Plus model combines traditional broadcast-style program/preview switching with advanced internal processing and monitoring tools. It features four M/E rows, 16 ATEM Advanced Keyers, two SuperSource processors, and a total of 12 DVEs, giving operators strong creative control for layered live graphics, picture-in-picture layouts, virtual set elements, and complex on-air transitions. The design also includes a front-panel LCD, headphone output, built-in speaker, and USB-C connectivity for local monitoring, software updates, and convenient control access.
In practical production use, the switcher is built to simplify large-format live workflows. Every input includes dedicated standards conversion, so sources arriving in different video formats can be aligned automatically to the switcher standard without external converters. Redundant SMPTE 2022-7 video connectivity, dual IEC power inputs, redundant control and PTP reference networking, and front-to-back cooling with four quiet fans all support reliable operation in continuous professional broadcast environments.
Core Features
- The switcher supports 64 native SMPTE 2110 IP inputs and 52 outputs, including multiview, for large-scale multicamera broadcast and live event production systems.
- Each input includes its own dedicated standards converter, allowing mixed incoming formats to be normalized automatically to the switcher standard.
- Redundant 100G fiber Ethernet ports support SMPTE 2022-7 seamless protection switching for robust signal reliability across separate network paths.
- Four M/E rows, 16 ATEM Advanced Keyers, two SuperSource processors, and 12 total DVEs provide extensive compositing and live effects capability.
- The built-in multiview system can display up to 64 views across four outputs with customizable layouts, labels, tally indicators, and VU meters.
- A rear USB-C webcam output allows the switcher to interface with streaming, conferencing, and presentation software on a connected computer.
- Dual IEC power inputs, redundant network connections, and a four-fan cooling design help support reliable long-duration professional operation.
Built for Large IP Workflows
The ATEM 4 M/E Constellation IP Plus is designed for higher-density SMPTE ST-2110 environments where larger source counts and output capacity are essential. With 64 inputs and 52 outputs, it is well suited to larger control rooms, broadcast facilities, and live production systems that need more scale than the standard model can provide.
Advanced Layering and On-Air Design
Its four M/E rows, 16 advanced keyers, 12 DVEs, and dual SuperSource processors give production teams extensive flexibility for lower thirds, chroma key work, branded show packages, multi-box layouts, and polished picture-in-picture effects. This makes it a strong fit for productions that require dense visual layering and more sophisticated program design.
Monitoring and Graphics Integration
The built-in multiview system supports up to 64 simultaneous views across four outputs, helping operators monitor large productions efficiently from a smaller number of displays. Built-in media players and internal graphics storage also allow stills and animations to be loaded directly into the switcher for faster on-air graphics workflow.
Broadcast-Ready Reliability
Beyond its channel count and effects tools, the switcher is designed for dependable live operation. Per-input standards conversion reduces compatibility issues, while redundant 100G connectivity, dual power inputs, redundant control and reference networking, and front-to-back cooling with four quiet fans help support stable performance in mission-critical environments.
