Blackmagic Design's ATEM 4 M/E Broadcast Studio 4K offers the extreme power of a 4 M/E 20 input 12G-SDI switcher combined with 16 ATEM Advanced Chroma Keyers that handles high frame rate Ultra HD formats, along with advanced creative features for creating the highest quality live broadcast programs. Ideal for challenging work and virtual set applications, this model also includes the latest technology and features such as 2 Ultra HD multi viewers, full 2D DVE, built in SuperSource compositing engine with 4 picture in picture DVEs, full re-synchronization on each 12G-SDI input and much more.

The multi rate 12G-SDI connections automatically switch between all HD and Ultra HD formats up to 2160p59.94 with a single BNC cable. Even if you're not working in Ultra HD now, the ATEM 4 M/E Broadcast Studio 4K has all the power and features for the highest end live production work, while being Ultra HD ready the instant you need it. There are 4 built in media players and a larger media pool with more memory for graphics and video clips and the ATEM 4 M/E Broadcast Studio 4K features 16 built in ATEM Advanced Chroma Keyers, dynamic transitions, a powerful DVE, SuperSource multi layering, power macros, audio mixing, camera control with color correction and much more.

Every input has automatic frame re-synchronization so customers can take any source, even if it’s not referenced, and make clean switches. There are also two balanced XLR audio inputs and outputs for connecting mixers and other pro audio gear. The ATEM 4 M/E Broadcast Studio 4K has both an Ultra HD program output as well as a down converted HD program output, along with 6 auxiliary outputs for sending clean feeds out to giant screens, projectors, recorders or monitors. Dual Ultra HD multi view outputs let customers monitor program, preview and cameras on large screen Ultra HD displays.

The ATEM 4 M/E Broadcast Studio 4K can be controlled using ATEM’s professional hardware control panels or using the ATEM Software Control on a Mac or Windows computer connected via ethernet.

NOTE: Blackmagic does not include IEC cables on this product. We recommend also buying a C2G 03133, a 6’ IEC universal power cable.
